GLMATRIXMODE(3gl)GLMATRIXMODE(3gl)NAME
glMatrixMode - specify which matrix is the current matrix
C SPECIFICATION
void glMatrixMode( GLenum mode )
PARAMETERS
mode Specifies which matrix stack is the target for subsequent matrix
operations. Three values are accepted: GL_MODELVIEW, GL_PROJEC‐
TION, GL_TEXTURE, and GL_MATRIX0_ARB, thu GL_MATRIX31_ARB The
initial value is GL_MODELVIEW.
DESCRIPTION
glMatrixMode 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.
GL_MATRIX0_ARB, thu GL_MATRIX31_ARB
Applies subsequent matrix operations to one of
the program matrix stacks which are used by
vertex and fragment programs.
To find out which matrix stack is currently the target of all matrix
operations, call glGet 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 glMatrixMode is executed between
the execution of glBegin and the corresponding execution of glEnd.
ASSOCIATED GETS
