Hi guys and welcome to this lecture where we are going to explore the point light.
Now before I move to Point light I just want to bring it to your attention that a parallel light has
a point of interest and the point of interest will determine where the intensity is focused if you move
it out OK.
Not is that the intensity is moving but the light itself still you know focusing towards your 3-D layers.
But so to change the type light sometimes you can come to light options and from here you change to
point or I like doing this is to come to the light like most of the time you come here because you will
have you will have a toilet up and then you change to point light.
Now as soon as you change to a point light.
OK.
Some properties it has the same kind of properties as the parallel light if you this but it's a point
and the point of interest has Zappia what how does it work.
You can imagine the light coming out of the light itself just from here and going towards your 3-D less
what the position of the high intensity is always coming out from the light not from the point of interest.
So let's for example bring it nearer to the layer.
OK.
And that's what's happening here.
It's getting brighter on the point and dimmer around the point of course whatever it is deemed it has
to do with the falloff distance and the radius maybe the radius.
OK you can decrease it or increase it if you like.
So you need to come and play with it.
Actually it's very nice.
It can move your life.
Now I really you have a point you know this is pretty good.
So you can take this point for example and you're doing some I don't know movies about aliens you can
play with this flight or even put it behind something like this is the 3-D layer here.
Let's open its position and take it forward.
OK.
Then you can take your flight over here and put it behind the layer.
Notice how the light is going to become very black.
OK.
You can do a lot of animation.
But the point is this is a point light and it points through that axis by the way you can rotate and
not is that the point of it.
This has Zippy's and you have only the position.
Let's change the color here and take it something nicer.
Just like this.
Actually this is all about the point light.
But but it's applications are very nice.
Thank you very much for listening for Pantelides.
I will see you in the next lecture.
