Hi guys and welcome to this new lecture about radiowaves and we are still in Wayfinder polygon and we
want now to look at the stroke and all its controls.
The stroke is about how the wave is drawn.
Let's come to one second or two here we notice now we have only thin lines and we can change the way
the stroke is drawn by using the profile and we have several options.
We can change the color which I will do now and change it to yellow.
I will be called for use it better.
And also we have the capacity to fade in time fadeout time and we had to start with and end with to
appreciate the profile and its options.
We need to start with now to become a bit thicker.
We make the stroke thicker.
So if I take it to 100 that's the maximum value you know is that the stroke are starting at 100.
You notice now that end with is five.
This is totally in relation with the lifespan of the lifespan to seven.
And then when you start reaching the lifespan the end with will take effect and it will disappear.
While it is only five in which you can put it at zero.
Now we have a double disappearance where it goes to zero.
Here you are and then it is completely disappearing.
Fine.
Let's go back to five here.
In fact we should go back to 100.
That would be better to show you the other effects.
Now we go back to profile since we have it with.
We can't really play with the profile.
Square is the default.
And Ill give you like a plain a shape that is a circle or maybe a polygon or 12 Sides whatever you want.
Let's go to triangle triangle is another format to draw the wave and it uses an algorithm that does
give you this kind of drawing where there is shading that is a line in between that has full color and
things like this.
It's up to you to start working with this.
The other nice options is so tooth out.
So now it's to think out or it has teeth to the outside.
If you take it back to 60:40 you will notice even how beautiful it could be.
So tooth in is just the opposite the fading is towards the inside and you have also the motion which
is pretty practical but not this size is a lot.
From the start and end with.
And also you have the bell which is another format that's pretty cool.
If you want to use it you notice the variations here and you have the last one which is signed.
It uses a strong algorithm to give you these kind of waves.
Here we are if we take it back you'll notice what is happening so profile is about how you want your
wave to appear and you have many options which are cool and interesting of course you should always
remember that you can use modes you can play compose on top of other solid layers and use modes and
so on you will have different kinds of waves.
Good.
We saw the color and we changed it.
Let's go to opacity that is that opacity is set to one by default.
The passage here goes from 0 to 1 only it's a factor it's a factor for the opacity of the layer.
For example the layer is at 100 percent capacity and the opacity here is set to 1.
It means it's going to take the full opacity of the layer.
So it's a factor 1 times 100.
This is the capacity that you'll get.
Let's go back to square.
If I put a positive to 0.5 then it's going to take half of the opacity of the layer and become you know
like 50 percent and you have to remember that you have it time and federal time the way they are feeding.
Well look at this now if you change the opacity of the layer at 50 you have a composite here 0.5 times
50.
So you are actually at 25 percent opacity here is very important because also it plays a role in the
fade in and fade out time.
Let's take it back to 100.
And here we also make 100 nobla.
Let's look at fade in time.
You notice that the fit in time by default is zero.
Fade in time is the time it will take the wave to be at full capacity.
So if you put a to one it's going to take one second for the wave to appear at full capacity of one
you notice how when he said one second the opacity here is at its full according to the opacity factor
here.
If you go for example to two and you say fade in time is two.
So it's going to take two seconds to reach the full opacity here you're pretty cool by the way.
And you can do quite some animation quite some tricks here.
That's very fine.
Let's go back to one for faith in time.
Now you have the fade out time the fade out time is directly related to the life span you know that
lifespan is seven.
We have put it there.
It means at seven seconds it will start disappearing completely and it's got the fade out time specifies
the amount of time it takes the wave to fade out of you fadeout time is measured backward in time from
the end of the lifespan meaning from lifespan.
Seven You will go backward to two because we have five minus seven.
That's two.
And this is when you start fading out.
So it's going to take five seconds for it to reach the complete lifespan and fade out completely.
If you put the Fed out time two three then you will have to go backward three seconds.
And this is where you start filling out you notice it is not filling out.
But from four that is seven minus three that is four it start fading out.
So this is critical and you know pretty powerful Let's go to six for example and put her fell time at
one.
So actually your way will be live at full capacity and we start feeding a six second and it's going
to fade pretty rapidly at 7:00.
So really it depends on what you want to do and how you want your animation to go.
Usually five is OK if you don't have anything specific but actually making it six or seven or five or
four whatever you want will be quite useful in feeding them before the lifespan.
Now what happens if you put it at 15 that is now higher than the life span itself.
Well what's going to do is start and you start fading already.
So it's going to remove everything before the 7:00.
So he had to fill out time now because it's higher than the lifespan is going to be seven.
So I start fading from the beginning.
OK.
Here you are and you got this at 7:00.
It goes.
So if you increase the value of federal time higher than the life span then it would take only the remainder
of 15 minus the lifespan and start feeding from there which will be from its birth so this is about
the stroke and how to control the stroke shape fitting in fitting out and with of course the start and
end to it.
But you're not very well when you combine the stroke with the wave motion and the producer point and
so on you can have excelled in the animation.
Thank you very much for listening in the next lecture we are going to look at.
Parameters are set at birth or each frame is going to be pretty interesting.
