NAME

rotate - rotates graphical primitives

SPECIFICATION

C
rotate(a, axis)
Angle a;
char axis;

FORTRAN
subroutine rotate(a, axis)
integer*4 a
character axis

Pascal
procedure rotate(a: Angle; axis: char);

DESCRIPTION

rotate specifies an angle and an axis of rotation.  The angle is given in tenths of degrees according to the right-hand rule.  The axis of rotation is defined by a character, either ´x´, ´y´, or ´z´ (the character can be upper or lower case).  rotate is a modeling command; thus, it changes the current transformation matrix.  All objects drawn after the rotate command is executed will be rotated.  Use pushmatrix and popmatrix to preserve and restore an unrotated world space.
