NAME

       SoMatrixTransform -

       The SoMatrixTransform class is a transformation node.

       This class is the most flexible transformation node, as you can use it to accumulate any
       kind of transformation matrix on top of the current model transformation matrix.

SYNOPSIS

       #include <Inventor/nodes/SoMatrixTransform.h>

       Inherits SoTransformation.

Detailed Description

       The SoMatrixTransform class is a transformation node.

       This class is the most flexible transformation node, as you can use it to accumulate any
       kind of transformation matrix on top of the current model transformation matrix.

       FILE FORMAT/DEFAULTS:

           MatrixTransform {

Member Function Documentation

   void SoMatrixTransform::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 SoTransformation.

   void SoMatrixTransform::doAction (SoAction *action) [virtual] This function performs the
       typical operation of a node for any action.
       Reimplemented from SoNode.

   void SoMatrixTransform::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 SoMatrixTransform::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 SoMatrixTransform::getBoundingBox (SoGetBoundingBoxAction *action) [virtual] Action
       method for the SoGetBoundingBoxAction.
       Calculates bounding box and center coordinates for node and modifies the values of the
       action to encompass the bounding box for this node and to shift the center point for the
       scene more towards the one for this node.

       Nodes influencing how geometry nodes calculates their bounding box also overrides this
       method to change the relevant state variables.

       Reimplemented from SoNode.

   void SoMatrixTransform::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 SoMatrixTransform::pick (SoPickAction *action) [virtual] Action method for SoPickAction.
       Does common processing for SoPickAction action instances.

       Reimplemented from SoNode.

   void SoMatrixTransform::getPrimitiveCount (SoGetPrimitiveCountAction *action) [virtual] Action
       method for the SoGetPrimitiveCountAction.
       Calculates the number of triangle, line segment and point primitives for the node and adds
       these to the counters of the action.

       Nodes influencing how geometry nodes calculates their primitive count also overrides this
       method to change the relevant state variables.

       Reimplemented from SoNode.
