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 {
               matrix 1 0 0 0
         0 1 0 0
         0 0 1 0
         0 0 0 1
           }

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.
