Description copied from class: PostProcessorEffect

Concrete objects shall be responsible to recreate or rebind its own resources whenever its needed, usually when the OpenGL context is lost. Eg., framebuffer textures should be updated and shader parameters should be reuploaded/rebound.

Specified by:

rebind in class PostProcessorEffect
