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: longint; axis: longint);

DESCRIPTION

rotate specifies an angle (a) and an axis of rotation (axis).  The angle (a) is given in tenths of degrees according to the right-hand rule.  The axis of rotation (axis) is defined by a character, either ´x´, ´y´, or ´z´.  (The character can be upper- or lowercase.) 

rotate is a modeling routine; it changes the current transformation matrix.  All objects drawn after rotate executes are rotated.  Use pushmatrix and popmatrix to preserve and restore an unrotated world space.
