Modelando um Machado Blender (Modeling a simple Axe) "Low Poly" ( How to model an simple Axe) - Duration: 41:16.

Let's trying to model an axe

(Numpad 3)

(Numpad 1)

(To scale is "S" and to Scale with a Axis press "X" or "Y" or "Z" on this Case I press "X")

(To enter edit mode press TAB)

(To cut press "ctrl + R")

I'll do a very simple

For you to be able to modify it anyway you want (Or you can use it without modify too)

(Scale to give the top, bottom or base use the same way Press "S" and Axis "X" "Y" or "Z" on Edit mode too)

Scale

Something you do not understood, you can ask

Let's use this*

So this is ..*

I'll press the "I"

To do it

I'll make a hole here I don't usually use Boolean because isn't good sometimes

because it can get errors in some Engine games**

This one I think I'll put merge

(To merge press ALT + M)

I think is better to merge this here

What I need to do here, I think I'll undo

I think i was not merged this object good

CTRL + Z

Extrude (Press "E") I'll extrude here

Now I'll merge

I'll scale here

I'll press S + Y

I'll check if the mouse cursor is in the center

(Menu of search Press "Spacebar")

(To Wireframe view press "Z")

I'm going to do it in a way to it's easy to put into games too and can modify easily too if you want

There's a many ways to unwrap/texturize this

But I like to do this way

unwrap from "Project from view" tool

(To use the "Project From View" make sure that the faces are aligned correctly with your vision)

This way make a correctly form

Fast and easy

It's just my opinion, you can do as you want*

I'm select others here

I need to deselect others here too

Press "U" and select "project from view"

Now we'll fix this

(To move UV layer press "G" and to Scale UV Layer press "S")

(To rotate this press "R")

(To align axis press "W" and select what you want *)

I'm let this empty space for the cable of the ax

I'll make sure if the UV layout is overlapping one another

Never forget to check this here. it's very important

If not, you can confuse this later.

Let's create a new image

It doesn't have to be a big image, because this is a simple model

Without alpha

I'm going to paint here

Change Light to "Hemi Light" to see better

I'll choose random color here

(That's why we need to make sure if UV layout is not overlapping another)

(LOL)

Let's make some things here and see which ones get better

Yes, now is good

This blender tool is not for that, but ...

To you get the result that you want, Anything goes XD

(The Ambient Occlusion Tool you find In The Bake)

Can get another shadow effect

I think if using the overlap effect gets better

( My dog is barking, sorry about this XD )

In the Image Sampling part you need to check the box Normal Map so blender can understand that it is a Normal Map file

(Keep the photoshop file for you to edit later, in case you need)

I didn't like this thing here

This way get better

Simple

A simple and Low Poly

Did we live in London in 2005?

Did they go away last week?

Did he work in bank 2005 - 2010?

Did she cook soup yesterday?

Did it rain a lot last autumn?

Very often the past simple ends in -ed (regular verbs).

But many verbs are irregular. They do not end in -ed.

In this case you need to learn the list of irregular verbs.

Hi, everybody!

My name is Alisha, today we're gonna be talking about simple past tense.

We're gonna talk about how to make simple past tense statements in English.

So let's get started!

Okay, so first, let's talk about when we should use the simple past tense.

Simple past tense statements for today are for actions that started and ended in the

past, so these are things that both started or began and ended in the past, both of those

must be true to use simple past tense.

The second point for today is these are actions which happened at a specific point in time,

so a specific point in time can be yesterday, it can be an hour ago, it can be last year,

it can be when you were a kid, all of these are a specific point in time, but the key

is that we know when the action happened.

So specific point in time is point two for this grammar point.

Third, we can use simple past tense for repeated actions in the past.

So things you did every week or every month, or every year, every summer, every hour, if

you like, but one point about this, make sure to include a frequency indicator if you want

to talk about an action that repeated in the past.

Frequency indicator, for example, I just mentioned a few, every week, every month, every year.

So frequency, meaning how often, an indicator shows how often you did that.

So you can use repeated actions with past tense to show, let's see, something you did

a lot in the past, for example.

So to give you a visual, the past is down here, now is this point here, and future is

up here.

When we use the simple past tense it's an action that started and ended in the past

somewhere before now, that's one.

It's at a specific point in time, so this action and this action, we know when they

happened, it could be this morning, it could be yesterday, for example, but we know when

these actions happen.

Third, we can use for repeated action, so maybe these actions repeat, but we know when

the repetition happened, we know when we repeated these actions, so it's okay to use simple

past tense to describe those.

Okay, so now we know when we should use simple past tense, we know why we should use simple

past tense, but how do we make simple past tense statements?

So, when you want to use the simple past tense to explain an action that happened in the

past, you need to conjugate your verb, you need to change your verb.

So that means when you're using a regular verb, you do verb + ed.

So verb + ed is the basic form for simple past tense verbs, but keep in mind this is

only for regular verbs, not all verbs are regular verbs.

So, for example, some common ones are talk, which becomes talked; start which become started;

and enjoy which becomes enjoyed.

Please be careful, however, you'll notice that the past tense form of verbs has a few

different pronunciations, so, for example, start becomes started, it has an ID sound

it's not an ED sound, but an ID sound.

You might hear a word like walked, also, which has a sort of T sound about it; walk becomes

walked; started becomes started; an ID sound.

And then there's also a sound like in breathed, a very soft D sound.

So there are three past tense verb sounds to listen for, an ID sound, started; a soft

D sound like breathed; and then a more hard T sound like walked.

So pay attention to that when you're trying to make these past tense verb conjugations.

Ok, but some verbs are irregular verbs.

Irregular verbs do not have a simple rule for understanding past tense conjugation.

How to change them in past tense, there's no rule for these, you simply have to practice,

you have to remember them, read them, listen to them until you can remember the correct

conjugation, the correct way to change these verbs into the past tense.

So, for example, some common ones are eat, which becomes ate; speak becomes spoke; and

make becomes made.

If you see a verb somewhere that seems a little odd, or you're not sure what the present tense

form would be, you can check a dictionary and try to remember it from there.

So, now we've talked about simple past tense, irregular and regular verbs, let's try to

use them to make some sentences.

I've prepared a few example sentences, so let's take a look.

Okay, first sentence, He ______ a towel and sunglasses to the beach.

So the verb here is bring, I want to use the verb "bring."

Bring, however, is an irregular verb, so I can't use the ED rule for regular verbs; the

correct conjugation is brought.

He brought a towel and sunglasses to the beach.

This is the correct conjugation here, so bring is an irregular verb.

Okay, let's go to the next sentence.

They ______ to the gym every day last week.

So here, I'm showing you a repeated action, here I'm using every day, this is a frequency

indicator, how often did I do that action; and last week shows the specific point in

time.

So I'm using both of these two points, in addition to a simple past, the basic simple

past structure here.

So the verb that we want to use here is "go," but go is an irregular verb so we can't use

go-ed, for example.

Go changes to went in the past tense, so went is the correct answer for this sentence here.

Okay, let's try the next one.

I ______ to tell my boss about my schedule.

So the verb I want to use here is "forget."

Forget is a very useful word, I think, to remember.

But again, forget is not a regular verb, forget is an irregular verb, so we cannot use the

ED form.

Forget in the past tense becomes forgot.

Ok, so, I forgot to tell my boss about my schedule is the correct sentence here.

Alright!

Let's go to something a little bit different, here's a negative sentence.

I don't think they _______ a reservation at the restaurant.

Ok, so here I'm using a phrase, I want to use the phrase "make a reservation," to make

a reservation.

So the verb here is "make," this was one of my example verbs for the irregular form.

So make becomes made.

I don't think they made a reservation at the restaurant is the correct verb form to use

here.

All right, the next sentence, we ______ junk food almost every day last month.

So here, again, I have every day, but I have almost here, so almost every day, not every

day but close to every day.

And then last month, last month is my specific point in time in this case.

So here we have junk food, that means that the verb we want to use is probably eat, and

we learned that eat is an irregular verb, there's no rule for conjugating this, we just

know that eat becomes ate.

We ate junk food almost every day last month.

Great.

Okay.

So next sentence has two spaces for verbs, actually.

Okay, so the next sentence that I've prepared I included because a lot of my students asked

about how to report information.

When you want to report information, share something that you heard from a friend, a

past tense action, you need to conjugate the reporting verb, for example, say becomes said,

or hear becomes heard.

You need to conjugate this verb and you need to conjugate the information that you heard.

So there are two past-tense conjugations that should happen when you report information.

Let's take a look.

So here we have She _____ she _____ a great time at the party.

So, here, she ____ a great time at the party, so we used the expression "to have a great

time."

To have a great time, again, have is an irregular verb so we conjugate it to had.

She had a great time at the party.

Okay, but then to report your speech, so someone gave you information, past tense, give becomes

gave you information, so the verb for giving information, a neutral way to pass information

is "say."

So to conjugate say into the past tense, it's an irregular verb, so we use said.

Say becomes said, so she said she had a great time at the party.

Okay.

Please be careful of your pronunciation with the word said, a lot of people I've heard

use say-d.

Say-d is not correct, so please use said.

It sounds like SED, the pronunciation, but it's said, SAID is the spelling.

Say becomes said.

She said she had a great time at the party.

Ok, so last one.

Okay, so the last example sentence for today includes spaces for a few different verbs.

I included this because I wanted to show you that you can use a lot of different information

in one sentence, just by connecting your past tense verbs together.

So let's take a look.

Okay.

Yesterday I _____ late, _____ shopping, and _____ to my mother.

Okay, so the verbs I want to use for this sentence are sleep, "go," and "speak."

These are all irregular verbs, there are no regular verbs in this sentence.

So sleep in past tense becomes slept; go in past tense becomes went; and speak in past

tense becomes spoke.

So here, in one sentence, I have explained three things about my day yesterday.

Yesterday I slept late, I went shopping, and I spoke to my mother.

So you can explain a lot of things with past tense and a few connecting words, in this

case, I've just used "and" to connect the last two things in this sentence.

So please keep this in mind when you're sharing information about your past events.

So today we talked about the simple past tense, and we talked about how to conjugate both

regular and irregular verbs.

It might seem a little bit difficult to understand which verbs are regular and which verbs are

irregular, but with some practice it will become easier.

Past Simple vs Present Perfect • When to use the Past Simple and NOT Past Perfect • Grammar - Duration: 5:40.

in this video lesson we've learning about the five uses of the simple past

tense when you should be using the past simple tense and not the present perfect

simple tense we'll go through five uses of the simple past tense when you should

use simple past tense and not the present perfect simple so that you are

not confusing and mixing these two tenses up when you are speaking in

English let's learn about it together

friends the simple past is a tense we use in the English language to describe

completed actions in the past In our last video lesson we learnt about

the present perfect simple tense which relates past actions to the present but

the simple past doesn't do this the simple past is used to describe

completed actions so that past event is not related to the present at all which

are simply reporting facts about what happened in the past let's go through

five examples so that you can better understand when you should be using the

past simple and not the present perfect tense in our first example we went to

In our first example, we went to Canada last summer here

Here we can see that a certain point in time is defined

Here, last summer is defined! if we define a certain time in the past such as last

week yesterday last year last winter last spring last autumn then we use the

simple past this is because this is a completed it's a finished action in the

past now if you wanted to express how often something happened then we would

use the present perfect simple tense for example I've been to Canada twice

in our second example we have the sentence I bought a bike here the

emphasis is on the action I bought a bike so if you'd like to put the

emphasis on the action then we use a simple past but if we wanted to

highlight the result of buying the bike then we would use the present perfect

simple tense for example I've bought on your bike and now it can go bike riding

every day here the emphasis is on the present and on the result of the past

action the emphasis is not under action happening in the past me buying the bike

the third sentence I finished book five minutes ago we are adding emphasis on a

certain time in the past here the past simple is being used because I want to

emphasize that I finished the book five minutes ago in our previous lesson I'm

when to use the present perfect simple and not the past simple I mentioned that

just and already a signal words for the present perfect simple if we were to

change the sentence and use the present perfect simple I would say I've just

finished reading this book here the emphasis is on the present that I've

just finished it so the emphasis is being put on the fact that I finished it

not long ago I just finished

fourth sentence I knew some Italian back in high school we use the simple past

because it's a finished action in the past so I knew some Italian I don't know

Italian now but I knew some Italian in high school so the emphasis is on me

having known Italian back in high school at the moment I don't know much Italian

but I knew tallien back in high school yeah there is no connection to the

present that's why we don't use the present perfect simple but we use a

simple past tense the fifth and final sentence my great-grandmother

way to Mexico five times we can see again that the action happened in the

past I've mentioned how many times three times and it happened completely in the

past it has no result or no effect on the prison friends they have it after

these two video lessons you should be able to effectively differentiate

between the past simple and the present perfect simple if you are still

struggling when to use the past simple or the present perfect simple tense make

sure to head over to my website for full lesson notes and more practice you'll

find the link just above here click that link

practice more and you'll see with practice and in time that it will get

better also do understand that maybe in your language you don't use the present

perfect simple tense so it can be confusing for you when you have to use

the past simple tense or the present perfect simple takes to finish up

What Separates "Million Dollar Ideas" From "Ideas" - Duration: 10:01.

Hey, what's up?

John Sonmez here from simpleprogrammer.com.

I am in Rome, Italy.

I'm actually in a park here and I thought I'd do a video as a response to one of the

videos that I did, to some of the comments I got on a video where I did this video talking

about my partner Josh Earl and how he had basically brought me the 50K and he had earned

the partnership and congratulating him on that.

I wanted to do a follow-up because I got some interesting comments on that.

I think some of you still aren't getting it.

It's fine.

I don't expect you to necessarily get it, but I want to address a couple of issues,

one of them being the idea that, "Oh, this wasn't what you said.

This wasn't fair.

This wasn't the deal.

This guy was your friend."

The other one being like, "It seems like you're a little bit hesitant, a little bit, maybe

sorrowful about giving away half your company.

You're an idiot.

Why would you give away half your company to this guy?"

First let's talk about the first one, this, "This wasn't the deal."

Of course, this wasn't the deal.

I don't have a standing deal.

I never promised and said that this was the deal.

I said this was an example that Josh had essentially brought me 50K.

He had done more than that, but I was just using that as an example.

What he had done is he had proved himself as someone who could generate—who could

use my resources, my audience, my platform.

Platform is probably the better word, in order to generate more money and to build more revenue

and to grow Simple Programmer.

He proved himself capable of doing that and for that reason I felt like it was worth the

investment to invest in him and to give him the opportunity to become a partner, someone

who I wanted to work with as well.

Some people still have misinterpreted that.

This is the last time I think I'm going to address that.

Here's the thing.

You have to understand this.

When yo come to me, and so many people do, with an idea, an idea is worthless.

I have—when I take a shit in the morning, I've got 10 million-dollar ideas I come up

with just on the toilet and most people could do that.

It's not a big deal.

Coming up with an idea is pretty much worthless.

Execution is what's important.

Not only that, but having the ability and the means to execute the platform, either

the money or the platform, all those other elements.

What I have, what I offer is that I have a huge platform.

I reach millions of developers every single month.

I've got a reputation.

I've got the system, the business, the engine, if you will, that can make money, that can

put out a message, that can do a lot of things.

I've got a very powerful engine, aside from my personal attributes, because those things

don't scale.

As much of a genius I would like to call myself, as charismatic as I would like to be, it doesn't

scale.

I can only make so many videos, I can only write so many blogposts, I can only have so

many ideas and I can only execute so much on my own.

I'm always looking for people to help me to leverage, to expand.

Now you, bringing to the table, what do you bring to the table?

If you don't have a platform you're not bringing—you can't make—when I say bring me 50K.

It's not like you can make that 50K on your own.

You couldn't.

Not to the extent—you see what I'm saying?

You could make 50K.

If you came to me—let me put it this way.

If you came to me with a suitcase, this thing is just—I'm about to just abandon this thing

right now.

If you came to me with a suitcase and you had $50,000 in it and you said, "Hey John,

here's the 50K.

I would like to become an intern at Simple Programmer and I'd like you to hire me or

to do some kind of business together with you."

I would say, "No, thank you.

Take your suitcase of 50K and invest that somewhere else, but don't invest it here because

I'm not interested in the money.

I'm interested in the person that can use my platform to generate 50K."

You see what I'm saying?

I'm interested in the person that takes initiative to create value and to prove that they can

create value before they're asking for some kind of value and return.

Do you see what I'm saying?

A valuable person that can actually leverage, because I don't need 50K.

I don't give a shit.

I don't need 50K.

I mean, what am I going to do with 50K?

I'm not looking for 50k.

That's the whole point.

If you come—I promise you, if you come to me with a suitcase, if you write me a check

for $50,000 I'm not going to hire you.

In fact, that's one way to be sure not to be hired and not to do business with me because

it's not about that.

It's about the ability to generate it with my platform.

You see what I'm saying?

So, I think a lot of you that still think that I'm trying to exploit or scam people,

that's fine, you can think that but you don't have what it takes.

You don't have the mentality and you're never going to as long as you think that way, because

you still think that it's a tit for tat.

You still think that everything that you do you should get paid for and that's fair and

it's a one-to-one and that's how it works.

Why should you make someone else money?

Because you don't understand risk and entrepreneurship and platform, you don't understand the value

of that and how that—the execution of an idea and the risk that you put into making

work is so much more valuable than the idea itself or than some stupid labor.

You can hire anyone to labor.

It's the person who can actually not only—not only come up with an idea, get stuff done,

take the risks involved or build the platform.

You've got to bring some kind of value.

The other value you could bring to me is another platform.

You could say, "Hey, I built this platform.

I reached half a million developers a month.

Let's join forces.

Let's do something.

Let's combine.

Synergistically we can make money."

That's the other concept there.

Anyway, I just wanted to address that so you guys understand.

First of all, like I said, hopefully you understand now what I'm talking about here.

I mean I've explained this several times now.

I mean some of you get it, I understand, but some of you just still don't get it.

You think that I'm trying to exploit people.

it's more of a filtering process.

It's more of—you're not even worth my time if you can't even generate—because the level

of the person that I want to work with and do business with is a person that can generate

50K pretty easily using the—it's not too hard for someone of a high level of skill

to generate, say 50K.

I'm just 50K out as a number, but to generate money using my platform, if you're smart,

if you got ideas.

If you can figure out—if you can't do that, that's sort of like the first step, then it's

not going to be worth my time to invest in you.

That's just how it is.

That's a general filter.

Again, there are other ways to provide this value.

There are other ways to prove your worth, but I'm only working with A players, A+ players.

That's the key.

That's the key to leveraging successfully and to be able to stay small and still have

a lot of momentum.

Those opportunities exist.

This is where we get into the whole Josh issue here which is that he proved himself.

Yes, he was already my friend.

Yes, I already knew him.

I had worked with him in the past.

That got him his foot in the door, but I cautiously hired him to do the copywriting.

I said, "Okay, well, he's doing some copywriting.

Let's see.

Let's look at the results."

I wasn't even thinking about making some kind of deal to offer him half of my company, but

he did such an awesome job and we work well together and I said, "Okay, I don't want to

lose this guy.

I want to make sure that I get him onboard.

I can see him helping me to grow this company because of the value that he's already created

and the value that he's already brought."

That's why that opportunity existed.

Again, it's all kind of the same thing.

There's no—I didn't ever make a video and say, "Here's the rules.

If you bring me $50,000 I will absolutely hire you" and Josh did that.

I never made that kind of a statement.

What I said was that if you basically—like this is the idea, or however you want to quote

me, the intention was that this is the idea, this is the kind of way, this is the thinking—this

is not a letter of the law thing, this is a spirit of the law thing.

This is, like I said, again, if you brought me a suitcase with $50,000 in it I'm not hiring

you.

I'm not doing business with you based on that because I don't need 50 grand.

What I need is a skilled entrepreneur, someone who has not just ideas, but the ability to

that's necessary to succeed in business and to really help me to grow.

Passive Transport: Simple Diffusion - Duration: 2:39.

Welcome to Passive Transport - Simple Diffusion.

Passive transport is the

movement of molecules across cell membranes without using any energy.

When cells use simple diffusion, molecules naturally move from an area of

high concentration, to one of low concentration through a permeable membrane.

The difference between the two sides is

called the concentration gradient.

Because passive transport doesn't require any energy,

the speed at which each side reaches equilibrium is entirely dependent on the

porosity of the membrane.

The more porous the membrane,

the faster the molecules diffuse.

Simple diffusion moves molecules from high to low concentration until

both sides are uniform or have reached an equilibrium.

Oxygen is the one molecule that

moves into cells using simple diffusion.

When the oxygen concentration outside of the cell is high, the molecules are able

to quickly cross the phospholipid bilayer and enter the cell.

The cell doesn't have to expend any energy to get the oxygen in, which is good because all

cells need oxygen to survive.

Let's look at this in action.

Note the difference in the high concentration

of molecules in side A versus side B.

The molecules and water

are permeable to the membrane inside of this beaker.

The molecules move randomly using kinetic energy.

They may collide into the walls and each other, or

they may move through an opening in the permeable membrane.

Because there are more molecules moving on side A,

there are also more collisions, so more

particles move from A to B than from B to A.

The amount of materials moving from

side to side is called net diffusion.

Net diffusion moves down the concentration

gradient from areas of high concentration to areas of low concentration.

The particles continue to move back and forth between side A and B

until they come to equilibrium.

That is, they move until the number of particles

on each side is equal.
