The SoBumpMapCoordinate class is a node for providing bump map coordinates to shape nodes.
When encountering nodes of this type during traversal, the coordinates it contains will be put on the state stack for later use by shape nodes. The bump map coordinates can be used to specify explicit coordinates for a bump map. The SoBumpMap node is used to specify a bump map for the shape nodes.
Note that an SoBumpMapCoordinate node will replace the bump map coordinates already present in the state (if any).
Also note that since the indexed shape nodes have no bumpMapCoordIndex field, the textureCoordIndex field will be used for selecting bump map coordinate indices. You can set the bump map coordinate binding using the SoTextureCoordinateBinding node. Bump map coordinates must therefore have the same binding as the texture coordinates for texture unit 0.
If you supply no bump map coordinates for a shape, the texture coordinates for texture unit 0 will be used.

SoBumpMapCoordinate::SoBumpMapCoordinate | ( | void | ) |
Constructor.
References point, SoField::setDefault(), and SoMField::setNum().
SoBumpMapCoordinate::~SoBumpMapCoordinate | ( | ) | [protected, virtual] |
Destructor.
void SoBumpMapCoordinate::initClass | ( | void | ) | [static] |
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
Reimplemented from SoNode.
void SoBumpMapCoordinate::doAction | ( | SoAction * | action | ) | [virtual] |
This function performs the typical operation of a node for any action.
Reimplemented from SoNode.
References SoMField::getNum(), SoAction::getState(), SoMFVec2f::getValues(), point, and SoFieldContainer::set().
Referenced by callback(), and pick().
void SoBumpMapCoordinate::GLRender | ( | SoGLRenderAction * | action | ) | [virtual] |
Action method for the SoGLRenderAction.
This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.
Reimplemented from SoNode.
References SoMField::getNum(), SoAction::getState(), SoMFVec2f::getValues(), point, and SoFieldContainer::set().
void SoBumpMapCoordinate::callback | ( | SoCallbackAction * | action | ) | [virtual] |
Action method for SoCallbackAction.
Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.
Reimplemented from SoNode.
References doAction().
void SoBumpMapCoordinate::pick | ( | SoPickAction * | action | ) | [virtual] |
Action method for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
References doAction().
Set of 2D points. Contains no points by default.
Referenced by doAction(), GLRender(), and SoBumpMapCoordinate().
