GLROTATE(3G) OpenGL Manual GLROTATE(3G) NAME
glRotate - multiply the current matrix by a rotation matrix C SPECIFICATION
void glRotated(GLdouble angle, GLdouble x, GLdouble y, GLdouble z); void glRotatef(GLfloat angle, GLfloat x, GLfloat y, GLfloat z); PARAMETERS
angle Specifies the angle of rotation, in degrees. x, y, z Specify the x, y, and z coordinates of a vector, respectively. DESCRIPTION
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. NOTES
This rotation follows the right-hand rule, so if the vector x y z points toward the user, the rotation will be counterclockwise. ERRORS
GL_INVALID_OPERATION is generated if glRotate is executed between the execution of glBegin() and the corresponding execution of glEnd(). ASSOCIATED GETS
