SPECIFICATION

C

FORTRAN

Pascal
procedure pushmatrix;

DESCRIPTION

pushmatrix pushes down the transformation matrix stack, duplicating the current matrix; i.e., if the stack contains one matrix, M, after a pushmatrix command it will contain two copies of M.  The top copy can be modified.  The stack is eight levels deep in hardware, and extends to 32 levels in software.
