I've recently encountered a strange problem after
integrating an OpenGL program into my Performer application.
My performer app uses clipmaps to draw terrain imagery, the
opengl application uses several textured quads to draw a
moving map. When running, the terrain that the clipmap
is supposed to be on, appears to be cycling through the
8 or 9 textures that the opengl moving map uses. It cycles
quite fast so the effect is a flashing terrain. The moving
map displays correctly. I currently have each application
displaying in separate channels, with separate draw callback
functions. In the opengl channel callback, I push the performer
matrix and the performer state, do the opengl thing, and pop
the state and matrix. This has always worked before with
opengl geometry, but I've never tried it with textures.
I don't know where the mailing list archives are now, so
I apologize if my question has been answered before.
Does anyone out there have any suggestions?
My current setup is:
Performer 2.4
Irix 6.5.13
1 - IR3 (2 - channels)
Thanks.
