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.
