> Just think – booleans that work, AND can be animated! < I think Santiago's wish for animated booleans has a fundamental difference from mesh-booleans that you are referring to. Animated booleans are usually calculated more like a z-buffer. Think of the way you can push two obects through each other in 3DS and the intersection is shown correctly when rendered. This is because the z-buffer determines which object is in front at the image level. In this sense, 3DS _does_ have animated _boolean unions_. Santiago's wish is for other boolean functions which work the same way. In the case of subtraction, the Z-buffer is used to determine which object is in back rather than in front. Well, this example is a little oversimplified, but hopefully you see what I'm getting at. — James — Choreo Motion —
