Post process shader

Introduction

Post process shader is a shader file format based on GLSL to simplify writing post process stage, where full screen quad is rendered with a custom fragment shader.

This file format is designed to specify this custom fragment code, and specify its input and output.

Format

Structure of the file:

 #using [samplerType] [samplerName]
 #using [attributeType] [attributeName]
 #using out vec4 [outVarName]
 [fragmentCode]

samplerType texture2d ...
samplerName any valid glsl sampler name
attributeType any valid glsl type
attributeName any supported attribute type (see ShaderIn). Currently only ShaderIn.uv is supported
outVarName any valid glsl variable name, except 'fragColor'.

Example:

 // Input declarations
 #using sampler2D diffuseSpecMap
 #using sampler2D lightFactorsMap
 #using vec2 uv
 // Output declaration
 #using out vec4 finalColor
 // Fragment code (don't declare output variable)
 vec4 diffuseSpec = texture2D(diffuseSpecMap, uv);
 vec4 lightFactors = texture2D(lightFactorsMap, uv);
 finalColor = diffuseSpec * lightFactors;
 finalColor = vec4(finalColor.rgb + finalColor.a, 1.0);
