SoBumpMapMatrixElement

NAME

SoBumpMapMatrixElement -

The SoBumpMapMatrixElement class is used to manage the bump map matrix stack.

The bump map matrix is used to transform bump map coordinates before being used to map bump maps onto polygons.

SYNOPSIS

#include <Inventor/elements/SoBumpMapMatrixElement.h>

Inherits SoAccumulatedElement.

Member Function Documentation

void SoBumpMapMatrixElement::initClass (void) [static]Initialize relevant common data for all instances, like the type system.

Reimplemented from SoAccumulatedElement.

void SoBumpMapMatrixElement::makeIdentity (SoState *const state, SoNode *const node) [static]Sets current texture matrix to identity.

void SoBumpMapMatrixElement::set (SoState *const state, SoNode *const node, const SbMatrix & matrix) [static]Sets the current texture matrix to matrix.

This method is an extension versus the Open Inventor API.
