glRotate(3G) OpenGL Reference glRotate(3G)
NAME
glRotated, glRotatef - 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 computes a matrix that performs a counterclockwise rotation of
angle degrees about the vector from the origin through the point (x, y,
z).
The current matrix (see glMatrixMode) is multiplied by this rotation
matrix, with the product replacing the current matrix. That is, if M is
the current matrix and R is the translation matrix, then M is replaced
with M ⊕ R.
If the matrix mode is either GLMODELVIEW or GLPROJECTION, all objects
drawn after glRotate is called are rotated. Use glPushMatrix and
glPopMatrix to save and restore the unrotated coordinate system.
ERRORS
GLINVALIDOPERATION is generated if glRotate is executed between the
execution of glBegin and the corresponding execution of glEnd.
