pushmatrix(3G)

pushmatrix - pushes down the transformation matrix stack

As shipped in IRIX 6.5.30. Unchanged since IRIX 6.5.

NAME
     pushmatrix - pushes down the transformation matrix stack

C SPECIFICATION
     void pushmatrix()

PARAMETERS
     none

DESCRIPTION
     pushmatrix pushes down the transformation matrix stack, duplicating the
     current matrix.  For example, if the stack contains one matrix, M, after
     a call to pushmatrix, the stack contains two copies of M. Only the top
     copy can be modified.

     pushmatrix operates on the single transformation stack when mmode is
     MSINGLE, and on the ModelView matrix stack when mmode is MVIEWING.  It
     should not be called when mmode is MPROJECTION or MTEXTURE.
