Detailed Description

Encapsulated OpenGL code for executing a specified fragment shader on every raster point in the current render target.

Member Function Documentation

getProgramId()

GLuint gramods::gmGraphics::RasterProcessor::getProgramId

(

)

Returns the program id.

The raster processor must be initialized. Otherwise this method will return zero.

init()

bool gramods::gmGraphics::RasterProcessor::init

(

)

Initialize the raster processor.

run()

void gramods::gmGraphics::RasterProcessor::run

(

)

Execute the raster processor on the current render target.

setFragmentCode()

void gramods::gmGraphics::RasterProcessor::setFragmentCode

(

std::string

code

)

Set the fragment shader code to run in the raster processor.

This must be called before init. This must be set.

setVertexCode()

void gramods::gmGraphics::RasterProcessor::setVertexCode

(

std::string

code

)

Set the vertex shader code to run in the raster processor.

This must be called before init. The default code will set gl_Position to (x y 0 1) where x and y are in the range -1 to 1.
