Detailed Description

RenderPostProcess class allows you to perform the final post-processing of the scene with a shader.

Values for the following variables are passed to the shader:
uniform sampler2D VSN_SCENE_COLOR_TEXTURE - texture with processed scene
uniform sampler2D VSN_SCENE_DEPTH_TEXTURE - texture containing scene depth buffer
varying vec2 VSN_TEXCOORD - texture coordinates
uniform mat4 VSN_VIEW_PROJECTION - product of projection and view matrices
uniform mat4 VSN_INV_VIEW_PROJECTION - matrix inverse to VSN_VIEW_PROJECTION
uniform vec2 VSN_SCREEN_SIZE - screen width and height
uniform vec2 VSN_INV_SCREEN_SIZE - inverted screen width and height
