A few people have developed custom renderers for DX in the past to drive
immersive devices.  (They participate in this mailgroup, and perhaps would
care to comment.)  In addition, Chikai Ohazama of SGI wrote a custom volume
rendering module about 18 months ago.  He used OpenGL volumizer
specifically to leverage the Onyx hardware for volume rendering.  The last
time I saw it was on a 16-way, multiple IR pipe system at
Supercomputing'98.  I asked him a few month ago if he was interested in
contributing it to OpenDX, and he said he would have to think about it.
Admittedly, there are issues of how relevant this hardware is for specific
types of data, but that's a separate discussion.  Since these were done
with commercial DX, the "closed" route was taken of writing a separate
module.  That approach can still be taken, which has some advantages.  On
the other hand, viewing and interaction is in a separate window...

In addition, Greg Abram added some support for Stereographics (Crystal
Eyes) with OpenGL in OpenDX.  There was some discussion about it a few
months ago and he posted the documentation.

Subject:  [opendx-dev] Is there a "big picture" for the source of ODX



    Hello,

    my question is simple, is there somewhere a document about the
source (directory, description, link between files). We'd like to modify
some parts of the source for 2 reasons.

    1 : we'd like to see if it's possible to use Volume rendering with
hardware option on us SGI Onyx2. By now we are not sure that this is
possible without completly recode the application... so we're looking
for explanations or descriptions of the structure of the source.

    2 : SGI has developped a library (MPU) for use of their cave (and
others periph stereo ...). The purppose is to keep the "same"
application (that genereate OpenGL) and use it independantly with 1
pipe, 2 pipes .... the pipe is the periph hardware on Onyx2 to use for
generating images.

    What do you think of these ideas ? Is it possible for someone who
know OpenGL to recode the parts of OpenDX ?

    Thank you for your answers, please cc to my email adress.
