Custom compile for PrimitiveTree to generate GLSL code

[David Braun]

I see that gp.compile calls python's eval on the str representation of a PrimitiveTree. Instead I want to compile to GLSL code.

For example, if the expr had been

lambda x, y, z: x+y*math.sin(z)

The GLSL code would be this text:

out float fragColor;

uniform float x;

uniform float y;

uniform float z;

main() {

    fragColor = x + y*sin(z);

}

I would also have functions that exist in GLSL but have no meaning in Python

fragColor = myLookup(x, y) + sin(z);

Has anyone done this kind of custom compilation?
