glmatrixmode(3)
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_PROJECTION, and GL_TEXTURE. The initial value is GL_MODELVIEW.
- Additionally, if the GL_ARB_imaging extension is supported, GL_COLOR is also accepted.
DESCRIPTION
glMatrixMode sets the current matrix mode. mode can assume one of four
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_COLOR Applies subsequent matrix operations to the
- color matrix stack.
- 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.
