keywords	vertex, fragment, geometry, shader

Purpose

Links all vertex, geometry, and fragment shaders encountered so far. Determines all active uniform parameters and uses the shader parameter modules to update the uniforms before the OpenGL shading language program is run. Allows to setup the geometry shader state for the shader program.

Details

Provides the following additional uniform parameters:

• vec4 oiv_ViewPosition - the first three components specify the viewpoint position, the fourth component is 0 for orthographic projection or 1 for perspective projection
• ivec2 oiv_ViewportSize - contains the current viewport size as determined from the Open Inventor state
• vec4 oiv_DiffuseColor - contains the current diffuse color and alpha value (1-transparency)
• int oiv_NumEnabledLights - provides the number of currently active OpenGL lights
