Description

The vertexProgram keyword instructs Doom 3 to execute the given vertex program to produce the image map for this stage.

Usage

vertexProgram [prog]

Parameters

• [prog] - The vfp to execute.

Example

distort the current frame using the normal map helmet_local.tga and heatHazeWithMaskAndVertex.vfp

{
   program                 heatHazeWithMaskAndVertex.vfp
   vertexParm              0               0                                          // texture scrolling
   vertexParm              1               10                                         // magnitude of the distortion
   fragmentMap             0               _currentRender
   fragmentMap             1               models/characters/sarge2/helmet_local.tga  // the normal map for distortion
}
