3DROTATOR PRODUCT VIEWER ADVANCED FEATURES API www.3DRotator.com

	Make a link on your page cause the 3DRotator viewer to rotate or zoom. Great for pointing out a feature on your product or teaching.
	OR Integrate with your flash movie allowing it to control the 3DRotator viewer in real time

		function MoveTo(xdegree, ydegree, xpan, ypan, zoom, time, relative, sharpen, callbackfunctionname)
			- where 
				xdegree and ydegree are in degrees, set to -1 for no change (double)
				xpan	and ypan are in percent, a value of 50 means centered, set to -1 for no change for absolute mode (double)
				zoom 	is how far zoomed in, from 1 to 10 times, set to -1 for no change for absolute mode (double)
				time 	is for rotation in milliseconds, can be = 0 for jump (double)
				relative is true or false, if true - values are change from current, false=values are absolute (boolean)
				sharpen is true or false, if true - the image is sharpened after rotation (boolean)
				callbackfunctionname is string name of javascript function to receive current displayed position of object. leave '' (blank) for no call back (string)

			- examples
				to zoom out, then rotate, then zoom back in to an absolute position use:
					<a onClick="RotatorMoveTo('RotatorViewer',180,60,50,50,5,100,false,true,'RotatorDisplayPosition');" href="javascript:void(0);" onMouseOver="window.status='See this part of the object';return true;">See This Part of the object</a>

				to rotate 20 degrees to the left while keeping the current zoom level, do not sharpen after
					<a onClick="RotatorMoveTo('RotatorViewer',-20,0,0,0,0,0,true,false,'');" href="javascript:void(0);" onMouseOver="window.status='Rotate 20 degrees to left';return true;">Rotate 20 degrees to left</a>

				to zoom to a new spot without rotating
					<a onClick="RotatorMoveTo('RotatorViewer',-1,-1,30,20,2,100,false,true,'');" href="javascript:void(0);" onMouseOver="window.status='Zoom to a particular spot';return true;">zoom to a particular spot</a>

				to zoom out from the current zoom without panning or rotating
					<a onClick="RotatorMoveTo('RotatorViewer',0,0,0,0,-1,100,true,true,'');" href="javascript:void(0);" onMouseOver="window.status='Zoom out';return true;">Zoom out</a>

				to pan diagonally without rotating or zooming
					<a onClick="RotatorMoveTo('RotatorViewer',0,0,-10,10,0,100,true,true,'');" href="javascript:void(0);" onMouseOver="window.status='Pan up-right';return true;">Pan up-right</a>
