I'm curious to know why you're going for the NeXT box over PEX. The NeXT is a nicely integrated system with a great user interface toolkit! It also has 3-D support built in, using the Renderman library. This last is under NeXT 3.0, not out yet, but it should be reasonably soon. (We're developing using a beta version.) NeXTs seem to be in moderately wide use in the mathematical community, which is our main target, though perhaps they're still not as widely used as Suns. > If you're going to go for Sun's Xgl, then you might as well do a PEX > port -- the concepts and terminology is almost virtually the same (not > surprising since Sun's Xgl is lifted from their knowledge of > SunPHIGS). We started on the XGL port a while back, before X11R5 came out. Most of the low-level code for XGL is done. Performance for anything other than wireframe is disappointing, though, which is part of the reason a generic X/PEX port is less appealing than it might be. The NeXT actually does a better job than a Sparcstation IPC with GX card, when we're using shaded surfaces. > > Want to try to convince us? > > I'm game. What does it take to convince you? :-) > > -- Rich So tell me about PEX. We don't have any systems with PEX-equipped X servers at the moment, nor PEX client libraries, though I understand there's something in X11R5. If we were to write for a "generic" PEX implementation, as opposed to something from a particular vendor, what features could we depend on? Is there a well-defined library interface so that we could expect to write portable code? Stuart
