.SH "Detailed Description"
.PP 
The \fBSoBumpMapTransform\fP class is used to define 2D bump map transformations\&.
.PP
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\&.

.PP
Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for run-time type checking and 'downward' casting\&. Usage example:
.PP
.PP
.nf
void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}
.fi
.PP
.PP
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in \fIall\fP 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 \fBInventor/nodes/SoSubNode\&.h\fP (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine\&.h (for engine classes) and so on\&.
.PP
For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups\&. 
.PP
Implements \fBSoBase\fP\&.
.SS "const \fBSoFieldData\fP * SoBumpMapTransform::getFieldData (void) const\fC [protected]\fP, \fC [virtual]\fP"
Returns a pointer to the class-wide field data storage object for this instance\&. If no fields are present, returns \fCNULL\fP\&. 
.PP
Reimplemented from \fBSoFieldContainer\fP\&.
.SS "void SoBumpMapTransform::doAction (\fBSoAction\fP *action)\fC [virtual]\fP"
This function performs the typical operation of a node for any action\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoBumpMapTransform::callback (\fBSoCallbackAction\fP *action)\fC [virtual]\fP"
Action method for \fBSoCallbackAction\fP\&.
.PP
Simply updates the state according to how the node behaves for the render action, so the application programmer can use the \fBSoCallbackAction\fP for extracting information about the scene graph\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoBumpMapTransform::GLRender (\fBSoGLRenderAction\fP *action)\fC [virtual]\fP"
Action method for the \fBSoGLRenderAction\fP\&.
.PP
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\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoBumpMapTransform::getMatrix (\fBSoGetMatrixAction\fP *action)\fC [virtual]\fP"
Action method for \fBSoGetMatrixAction\fP\&.
.PP
Updates \fIaction\fP by accumulating with the transformation matrix of this node (if any)\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoBumpMapTransform::pick (\fBSoPickAction\fP *action)\fC [virtual]\fP"
Action method for \fBSoPickAction\fP\&.
.PP
Does common processing for \fBSoPickAction\fP \fIaction\fP instances\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SH "Member Data Documentation"
.PP 
.SS "\fBSoSFVec2f\fP SoBumpMapTransform::translation"
Texture coordinate translation\&. Default value is [0, 0]\&. 
.SS "\fBSoSFFloat\fP SoBumpMapTransform::rotation"
Texture coordinate rotation (around z-axis, s is x-axis and t is y-axis)\&. Defaults to an identity rotation (ie zero rotation)\&. 
.SS "\fBSoSFVec2f\fP SoBumpMapTransform::scaleFactor"
Texture coordinate scale factors\&. Default value is [1, 1]\&. 
.SS "\fBSoSFVec2f\fP SoBumpMapTransform::center"
Center for scale and rotation\&. Default value is [0, 0]\&.
