rotate Library Method
Short Description: Rotate around given point and axis
Signature: t.rotate (px,py,pz, ax,ay,az)
Group: Motion
Class: transition Class
Makes the object rotate around the point (px,py,pz) with the axis (ax,ay,az).
(px,py,pz) denote the Coordinates of the center point
of the rotation.
px..az must be numbers which can be integer or floating point.
The vector (ax,ay,az) must be a unit vector, i.e. it must have length 1.
For example (ax,ay,az)=(0,0,1) makes the object rotate around the z-axis,
i.e. inside the screen plane.
Per default a full rotation of 360 dregrees is performed. This can be changed using
the rotatePart function. In order to rotate an object around its center
refer to rotateMiddle.
A transition may perform a single rotation and a single motion with constant acceleration.
So only of the rotate or rotateMiddle methods may
be called once per transition. If a motion with constant acceleration is defined as well,
then the center point (px,py,pz) refers to the end point of the
motion with constant acceleration. So conceptually the object is first drawn at the end point,
then rotated, and then moved to the point where
it belongs w.r.t. the motion with constant acceleration.

var a=taccgl.actor("testimg"); a.rotate(a.x0,a.y0,0,0,0,1).start(); | RUN |
var a=taccgl.actor("testimg"); a.rotate(a.x0,a.y0+a.hy0,0,1,0,0).start(); | RUN |
var a=taccgl.actor("pgMiddleColumnTable"); a.rotate(500,500,500,0,1,0).start(); | RUN |
var a=taccgl.actor("pgMiddleColumnTable"); a.rotate(500,500,-500,0,1,0).start(); | RUN |
var a=taccgl.actor("pgMiddleColumnTable"); a.rotate(500,500,-500,1/Math.sqrt(2),1/Math.sqrt(2),0).dur(5).start(); | RUN |
var a=taccgl.actor("pgMiddleColumnTable"); a.rotate(500,500,-500,1,1,0).dur(5).start(); | RUN |
