: I have a customer who is trying to run Performer 1.2 on a
: Certain Impact system. He is getting the following error.
:
: Error: Performer warning (2): Unable to determine graphics
: type 15 default VGXT using gfx type mode = 0x8010003
:
: Performer comes up, but it doesn't run. He says it's not hung,
: but the functionality is not there. (He is sending me email
: with the details.)
:
: Right now, upgrading to Performer 2.0 is not an option for him.
: Is there any way to make Performer 1.2 function properly on his
: Certain Impact system ?
Now this is an interesting situation. The customer has a Performer 1.2
application (which uses IRIS GL) and they have bought the very powerful
desktop OpenGL machine, Indigo2/IMPACT, yet switching to the OpenGL
version of Performer (IRIS Performer 2.0 contains both IRIS GL and
OpenGL libraries) is out of the question as far as they are concerned.
My advice is to go back to the customer and explain that porting
to 2.0 is really not that difficult, and that all registered 1.2
users with software maintenance get a free copy, etc., and see if
there is some way to make the transition happen. Point out that the
fast Impact demos (Mekton, Certain Impact, etc.) are Performer 2.0
OpenGL based and *do not use Performer 1.2 in any way*.
If they *really* must get 1.2 to work on their Impact system then
they need to understand exactly what the IGLOO (IRIS SL on OpenGL)
compatability environment is doing right and wrong with their
application. IGLOO seems pretty solid to me now, but has had to go
through several iterations to get there -- perhaps a newer versoion
of IGLOO would be of service.
Warn them that the performance of the Performer 1.2 (IRISGL) -> IGLOO
-> OpenGL route is certainly far from optimal (as opposed to Performer
2.0 in OpenGL directly with Impact/OpenGL enhancements) and that by
clinging to the past they are seriously mortgaging their future.
