The SoModelMatrixElement class is used to manage the current transformation.
SoModelMatrixElement contains the object-to-world matrix. 
The world-to-camera transformation is stored in the SoViewingMatrixElement class.
Note that one thing that can be a little confusing with the API is that SoModelMatrixElement does not contain the same matrix as the OpenGL GL_MODELVIEW matrix.

          | void * SoModelMatrixElement::createInstance | ( | void |  | ) |  |  | static | 
 
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

          | SbBool SoModelMatrixElement::matches | ( | const SoElement * | element | ) | const |  | virtual | 
 
This function returns TRUE is the element matches another element (of the same class), with respect to cache validity.
If the application programmer's extension element has a matches() function, it should also have a copyMatchInfo() function. 
Reimplemented from SoAccumulatedElement.
