POINT EXPRESSIONS

This one is less of a tutorial and much more a list of fun experiments.

I have been playing around Mads Hagbarth's  HigX Pointrender since

it has been released and it was always a lot of fun!

If you haven't used it I absolutely recommend to give it a go

as it opens many new possibilities for compositors.

For better understanding of how this super

plugin works I recommend to check out
Erwan Leroy's and Xavier Martin's site.

Here I was trying to explore a less straight forward use of the plugin which is a 

PointExpression node that let's you create really funky shapes

using a same mathematical functions that you would use in 

the native Expression node too. 

So in the following examples I am using simple setups with a turntable

Camera_Around gizmo I made for this plugin earlier

with some additional 2D nodes:

Also in the images you can see the Variables where they should

be in an Expression node but if you want to animate

the shapes you can add a Floating Point Slider.

Here are the steps to do it:

1 - Right click on the Point_Expression node and choose Manage User Knobs...

2 - Next to a list of knobs go to Add then choose the first option, Floating Point Slider

3 - Type the Name and the Label of your knob and choose values you`d like.

Make sure the Name is matching with the variable used in the Expression.

4 - Yay! Now you have a custom knob on your node that you can animate!
Have fun!

Instead of doing manually you can also use a python

snippet to add a knob to your node.
