Posted is a stack that demonstrates an interesting aspect of polygon graphics, and a way these graphics can be used to create 3D shapes and animations. Be sure to read the explanation included in the stack.
Tutti 3D is available on RevNet and via our Media Panel. Enter the following in your message box:
go url "http://www.tactilemedia.com/tmpanel.rev";
(OK, the stack name is clearly a misnomer. The stack does not cover everything [tutti] 3D. Instead, use a lazy American accent to pronounce 'tutti' and you wind up with 'too-dee', as in 2D. 2D - 3D. Get it?...)

Scott,
Dazzling! Imaginative! Great use of multiple technologies.
Putting the data into custom properties, rather than attempting to create the data natively on the fly, is certainly a great way to achieve speedy graphics. Who would have thought RunRev could produce such effects?
Congratulations!
Jim
P.S.
I don't know if this helps much, but you might be able to speed up the point rotation with the following modification. You don't have to cycle through the point list twice, i.e. "repeat for each" twice.
On rotatePoly theGraphic, thePivot, theAngle put the points of graphic theGraphic into tPoints
put item 1 of thePivot into xPivot put item 2 of thePivot into yPivot
put empty into newPointList
put sin(theAngle* pi/180) into S put cos(theAngle * pi/180) into C
--Set points relative to pivot
repeat for each line tLine in tPoints
put (item 1 of tLine)- xPivot into theX
put (item 2 of tLine)- yPivot into theY
put round(C*theX+ S*theY + xPivot)& comma after rotPtlist
put round(-S*theX + C*theY+ yPivot)after rotPtlist
put return after rotPtList
end repeat
set the points of graphic theGraphic to rotPtlist
end rotatePoly _______________________________________________ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
