Pops the transformation matrix stack.
FORTRAN (libfgl.a)
void popmatrix( )
SUBROUTINE POPMAT
The popmatrix subroutine pops the viewing transformation matrix stack.
This subroutine is not valid when the system is in projection matrix mode (mmode(MPROJ);), because the matrix stack is not accessible in this mode.
The example C language program backface.c uses the popmatrix subroutine, to restore the previous transformation matrix after altering it with the translate modeling subroutine.
This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.
