Well, apparently DEC misleads by omission, not commission. There is a listing in the
SPD that tells what boards are supported by Open3D 4.4 (I downloaded latest version in frustration).
It includes the Powerstorm 4DnnT as well as many others. Then there is a list of OpenGL support.
Then there is a list of PEX support. the 4DT boards are not in this list. And others have informed
me that PEX will probably not be added.
So, when Open3D was first hyped, it supported both PEX and OpenGL (in fact, the initial versions may
have supported PEX only). I guess it would be reasonable to assume anything called Open3D would
continue to do that. Answer is No. Brian Sheehan <sheehan_at_scripps.edu>, quoted AVS:
" We support ANY graphics card you can get DEC Phigs for. Sadly Dec are
no longer supporting Phigs so some of the newer cards are
unsupported. For AVS 5.4 we were hoping to move the DEC platform over
to OpenGL and so newer cards will be supported while older cards will
not (unless DEC produces OpenGL libraries for them)."
Well, my only PEX application is AVS, which has promised to have an OpenGL version Real Soon Now
(end of year). But my maintenance has run out, so I'll have to reinvest just to get a compatible
version to my workstation. Bleeah - have to do additional homework the next time.
By the way, AVS is partly wrong. PHIGS is supported by DEC on this card, using OpenGL for display!
But display support for AVS requires PEX.
