This is probably my fault, I am just asking if someone would have a
hint...
In my application I am getting my texture memory corrupted when I move
to a different partof my scene hierarchy that has mostly different
textures. The problem clearly has something to do with texture loading,
since nothing weird happens if I start from the offending part of the
scene. I am running on Hing Impact with 4TRAM, IRIX 6.2 and Performer
2.1.
Questions:
1. Should Performer automatically unload textures from hardware tex
memory when all geometry that uses them is out of view/removed from
graph? I have an image billboard that changes from time to time, and
according to Performer statistics, the system starts paging textures
constantly after 5 or 6 texture changes (the texture is 256x256, 8 bit
per component)
2. Should Performer handle correctly situation where all textures don't
fit in HW tex memory?
If you have any other ideas about what could cause texture corruption, I
would be very happy to hear of them.
