Detailed Description
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.
