Detailed Description ​

cpp
class Vp::Shader;

Base class for shaders.

Note that shader objects are just a facade/API for the glsl shaders. They shouldn't store state across frames and should have ALL their variables and uniforms set before each use. However sometimes it makes sense to store values in them. Just be aware that shaders are shared between many objects.
