4x4 matrix class.

This is the abstract base class for all state elements.
Definition SoElement.h:96
Element that stores the current projection matrix in GL.
static void initClass()
Initializes the SoGLProjectionMatrixElement class.
virtual void pop(SoState *state, const SoElement *prevTopElement)
Override pop() method so side effects can occur in GL.
virtual void setElt(const SbMatrix &matrix)
Sets the matrix in an instance. Has GL side effects.
