Hello Jonathan,
sorry that it took so long to get back to the problem, but I have been
overwhelmed with other work :)
Now I have made some tests to find out why it crashes. I think the reason is
the Octane V12 has a default visual of 30bits colour depth, because that's the
one it grabs in the offscreenrenderer. Tuning the machine down to 24bit is
possible and works around the problem, but I don't think this is the
appropriate solution. Unfortunatelly my knowledge about acquiring Xvisuals is
exactly NULL :(
BTW: Would it be possible to rewrite the Offscreenrenderer to use PBuffers ?
Would this speed up things (i am making about 8-100 screenshots in sequence) ?
What graphics have support for it, I know only SGI and nVidia ? Is the maximum
possible resolution different to the current one ?
Regards
Matthias
