Detailed DescriptionThe SoBumpMapTransform class is used to define 2D bump map transformations. Bump maps applied to shapes in the scene can be transformed by 'prefixing' in the state with instances of this node type. Translations, rotations and scaling in 2D can all be done. The default settings of this node's fields equals a 'null transform', ie no transformation. FILE FORMAT/DEFAULTS: BumpMapTransform {
translation 0 0
rotation 0
scaleFactor 1 1
center 0 0
}

Member Function Documentation
SoType SoBumpMapTransform::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
}
else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {
SoGroup * group = (SoGroup *)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 * SoBumpMapTransform::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 SoBumpMapTransform::doAction (SoAction * action) [virtual]This function performs the typical operation of a node for any action. Reimplemented from SoNode. References SoAction::getState(). Referenced by callback(), GLRender(), and pick().
void SoBumpMapTransform::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 SoBumpMapTransform::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 doAction().
void SoBumpMapTransform::getMatrix (SoGetMatrixAction * action) [virtual]Action method for SoGetMatrixAction. Updates action by accumulating with the transformation matrix of this node (if any). Reimplemented from SoNode.
void SoBumpMapTransform::pick (SoPickAction * action) [virtual]Action method for SoPickAction. Does common processing for SoPickAction action instances. Reimplemented from SoNode. References doAction().
