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:

  • name and/or identifier,
  • value.

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.
