NAME
fglMatrixMode - specify which matrix is the current matrix
FORTRAN SPECIFICATION
SUBROUTINE fglMatrixMode( INTEGER*4 mode )
PARAMETERS
mode Specifies which matrix stack is the target for
subsequent matrix operations. Three values are
accepted: GL_MODELVIEW, GL_PROJECTION, and
GL_TEXTURE. The initial value is GL_MODELVIEW.
DESCRIPTION
fglMatrixMode sets the current matrix mode. mode can assume
one of three values:
GL_MODELVIEW Applies subsequent matrix
operations to the modelview matrix
stack.
GL_PROJECTION Applies subsequent matrix
operations to the projection matrix
stack.
GL_TEXTURE Applies subsequent matrix
operations to the texture matrix
stack.
To find out which matrix stack is currently the target of
all matrix operations, call fglGet with argument
GL_MATRIX_MODE. The initial value is GL_MODELVIEW.
ERRORS
GL_INVALID_ENUM is generated if mode is not an accepted
value.
GL_INVALID_OPERATION is generated if fglMatrixMode is
executed between the execution of fglBegin and the
corresponding execution of fglEnd.
ASSOCIATED GETS
fglGet with argument GL_MATRIX_MODE
