Detailed Description

The SoShaderStateMatrixParameter class is used to define a matrix as shader parameter whose content is derived from the traversal state. Unlike other parameter classes, SoShaderStateMatrixParameter does not have a value field. The value member is protected and updated automatically from the traversal state.

Member Enumeration Documentation

  enum SoShaderStateMatrixParameter::MatrixType
Defines the different matrix types.

  enum SoShaderStateMatrixParameter::MatrixTransform
Defines different transformations that can be applied to a matrix.

Member Function Documentation

  SoType SoShaderStateMatrixParameter::getClassTypeId (void ) [static]
This static method returns the SoType object associated with objects of this class.

  SoType SoShaderStateMatrixParameter::getTypeId (void ) const [virtual]
Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Reimplemented from SoUniformShaderParameter.

  const SoFieldData ** SoShaderStateMatrixParameter::getFieldDataPtr (void ) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
 Returns the SoFieldData class which holds information about fields in this node.

  const SoFieldData * SoShaderStateMatrixParameter::getFieldData (void ) const [protected], [virtual]
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoUniformShaderParameter.

  void SoShaderStateMatrixParameter::updateParameter (SoGLShaderObject * shaderObject) [virtual]

Updates the shader parameter in the OpenGL state with the content of the value field.

Implements SoUniformShaderParameter.

  void SoShaderStateMatrixParameter::updateValue (SoState * state) [virtual]
Updates matrix value from state

Member Data Documentation

  SoSFEnum SoShaderStateMatrixParameter::matrixType
Defines the matrix type value for the uniform shader variable.

  SoSFEnum SoShaderStateMatrixParameter::matrixTransform
Defines a transformation that is applied to the matrix value. The default value of IDENTITY keeps the value unchanged.
