1991-2006 Silicon Graphics, Inc. glRotate 3G glRotate multiply the current matrix by a rotation matrix void glRotated GLdouble angle GLdouble x GLdouble y GLdouble z void glRotatef GLfloat angle GLfloat x GLfloat y GLfloat z angle Specifies the angle of rotation, in degrees. x y z Specify the x, y, and z coordinates of a vector, respectively. glRotate produces a rotation of angle degrees around the vector x y z . The current matrix (see glMatrixMode) is multiplied by a rotation matrix with the product replacing the current matrix, as if glMultMatrix were called with the following matrix as its argument: x 2 ⁡ 1 - c + c x ⁢ y ⁡ 1 - c - z ⁢ s x ⁢ z ⁡ 1 - c + y ⁢ s 0 y ⁢ x ⁡ 1 - c + z ⁢ s y 2 ⁡ 1 - c + c y ⁢ z ⁡ 1 - c - x ⁢ s 0 x ⁢ z ⁡ 1 - c - y ⁢ s y ⁢ z ⁡ 1 - c + x ⁢ s z 2 ⁡ 1 - c + c 0 0 0 0 1 Where c = cos ⁡ angle , s = sin ⁡ angle , and x y z = 1 (if not, the GL will normalize this vector). If the matrix mode is either GL_MODELVIEW or GL_PROJECTION, all objects drawn after glRotate is called are rotated. Use glPushMatrix and glPopMatrix to save and restore the unrotated coordinate system. This rotation follows the right-hand rule, so if the vector x y z points toward the user, the rotation will be counterclockwise. GL_INVALID_OPERATION is generated if glRotate is executed between the execution of glBegin and the corresponding execution of glEnd. glGet with argument GL_MATRIX_MODE glGet with argument GL_COLOR_MATRIX glGet with argument GL_MODELVIEW_MATRIX glGet with argument GL_PROJECTION_MATRIX glGet with argument GL_TEXTURE_MATRIX glMatrixMode, glMultMatrix, glPushMatrix, glScale, glTranslate Copyright 1991-2006 Silicon Graphics, Inc.
