I was looking into the lighting issues Felix reported with the xscreensaver pulsar hack (when running it with the -light option). One side of the planes looks good, the other one is black, so I thought it might be related to two-sided primitives.
Indeed, the hardware TCL code has a fallback for this if the material is different on both sides. If I hardcode that to always trigger (in check_twoside_fallback() in radeon_state.c), pulsar looks good with lighting. So I thought I'd see if this was related to some lighting oddities in bzflag, and I made another interesting discovery: with this fallback, it locks up the chip when connecting to a server, like I reported before for software TCL. In summary, there seem to be multiple problems related to two-sided lighting in the radeon driver, both with hardware and software TCL. I'll keep looking into them, but I hope this information will help someone else find them more quickly. -- Earthling Michel Dänzer (MrCooper)/ Debian GNU/Linux (powerpc) developer XFree86 and DRI project member / CS student, Free Software enthusiast ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
