NAME

6       glRotate - multiply the current matrix by a rotation matrix
7

C SPECIFICATION

9       void glRotated(GLdouble angle, GLdouble x, GLdouble y, GLdouble z);
10
11       void glRotatef(GLfloat angle, GLfloat x, GLfloat y, GLfloat z);
12

PARAMETERS

14       angle
15           Specifies the angle of rotation, in degrees.
16
17       x, y, z
18           Specify the x, y, and z coordinates of a vector, respectively.
19

DESCRIPTION

21       glRotate produces a rotation of angle degrees around the vector x y z.
22       The current matrix (see glMatrixMode()) is multiplied by a rotation
23       matrix with the product replacing the current matrix, as if
24       glMultMatrix() were called with the following matrix as its argument:
25
26       x 2 ⁡ 1 - c + c x ⁢ y ⁡ 1 - c - z ⁢ s x ⁢ z ⁡ 1 - c + y ⁢ s 0 y ⁢ x ⁡ 1
27       - c + z ⁢ s y 2 ⁡ 1 - c + c y ⁢ z ⁡ 1 - c - x ⁢ s 0 x ⁢ z ⁡ 1 - c - y ⁢
28       s y ⁢ z ⁡ 1 - c + x ⁢ s z 2 ⁡ 1 - c + c 0 0 0 0 1
29
30       Where c = cos ⁡ angle, s = sin ⁡ angle, and x y z = 1 (if not, the GL
31       will normalize this vector).
32
33       If the matrix mode is either GL_MODELVIEW or GL_PROJECTION, all objects
34       drawn after glRotate is called are rotated. Use glPushMatrix() and
35       glPopMatrix() to save and restore the unrotated coordinate system.
36

NOTES

38       This rotation follows the right-hand rule, so if the vector x y z
39       points toward the user, the rotation will be counterclockwise.
40

ERRORS

42       GL_INVALID_OPERATION is generated if glRotate is executed between the
43       execution of glBegin() and the corresponding execution of glEnd().
