Detailed Description

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.

Member Function Documentation

SoType SoBumpMapCoordinate::getClassTypeId (void) [static]

This static method returns the SoType object associated with objects of this class.

Reimplemented from SoNode.

SoType SoBumpMapCoordinate::getTypeId (void) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Usage example: 

  void foo(SoNode * node)
  {
    if (node->getTypeId() == SoFile::getClassTypeId()) {
      SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
    }
  }

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Implements SoBase.

const SoFieldData ** SoBumpMapCoordinate::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.

Reimplemented from SoNode.

const SoFieldData * SoBumpMapCoordinate::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 SoFieldContainer.

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.

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.

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.

void SoBumpMapCoordinate::pick (SoPickAction *action) [virtual]

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.
