Very interesting question… IXP's give you all the info about the view you need for the z-buffer, but they don't give you access to object information. There's really no way to do it in R2. In R3, you could attach an AXP to each object and each object would dump out it's transformed world coordinates and face information to a disk file. An IXP could then process it with the view information to turn it into a z-buffer. What you _really_ want is access to our internal z-buffer, but since we don't keep it around (to save memory), it's not available. However, you've already given me some bad ideas for R4… Thanks, – G
