Re: [Jrman-user] current status

[Gerardo h. <ma...@gm...>]

I just did one quick test with Pixie a few months ago so I really
wouldn't be able to make an accurate comparison between Pixie and
jrMan.

From time to time we compara Aqsis and jrMan and we believe that:

1. Aqsis is, by far, a much more complete implementation of the
Renderman Spec. Basically they seem to have implemented almost
everything, while in jrMan we still have a big list of unimplemented
featurees.

2. From our tests it seems that jrMan is faster than Aqsis. When
running both programs on an Intel machine (the Mac OS X implementation
of Java is not as fast as the Sun JDK on Intel) jrMan is faster than
Aqsis, especially if you use the java -server option. On complex
scenes jrMan is about twice as fast as Aqsis.
