Detailed Description

VSG extension Abstract base class for all uniform shader parameter nodes.

This is the abstract class from which all the uniform shader parameter nodes, e.g. SoShaderParameter1i, are derived.

These nodes allow users to provide uniform parameters to a given shader object, e.g. SoFragmentShader.

Uniform shader parameter nodes are usually added to the shader object's parameter field to affect only that specific shader program. They can also be inserted in the scene graph after an SoShaderProgram. In this case they affect whatever shader program is in effect when a shape is rendered.

Each parameter is defined by the following properties:

See the base class SoShaderParameter to get information about how to specify the name and/or identifier of a parameter.

The following examples show how to set a parameter named "scale" in two different ways.

Shader language.

Deprecated:

Deprecated since Open Inventor 9500
This enum will not be supported in Open Inventor 10.
Enumerator:
VERTEX 

Parameters of the vertex shader will be modified by this node when the shader source type is ARB/CG_PROGRAM.

FRAGMENT 

Parameters of the fragment shader will be modified by this node when the shader source type is ARB/CG_PROGRAM.

Member Data Documentation

ARB and CG shaders allow a vertex and a shader program to use the same name for a parameter.

When the SoShaderParameter is inserted in the scene graph, this field allows you to specify if this parameter applies to the vertex shader or the fragment shader. It has no effect on GLSL shaders. Use enum ShaderType. Default is VERTEX.

NOTE: field available since Open Inventor 6.0

Deprecated:

Deprecated since Open Inventor 9500
CG and ARB shaders will not be supported in OIV 10, please use GLSL instead.
