HI All: this list is great, lots of good information so far. ok here's the question: I have a scene in a universe, it a college campus with lots of small buidling models overlayed on a big 3d model. so the big 3d model is just buildings as squares, and we have specific buildings which we details/texture stuck in the scene. we have the big model transparent so it all looks nice. Id like to create an area within the scene in which nothing is rendered. say a cube which i can define and within the cube the view should be blank, so that if i move the viewing platform there i get a clear view towards the closests objects outside the cube. and i can't stick in a solid background color cube becuase then if i move there i would only see solid blank. any ideas would help. ~shlomo =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
