Thread: Stereo Rendering Problems - nVidia geForce GTX 260M

-

im finding 3d rendering @ standstill due either video card, linux drivers, or who-knows-what. put, until maybe year or ago, able render stuff maya using video card's stereo buffer no problem.

@ point (possibly due kernal update -- seems unlikely), getting horrible artifacts in maya renders. following error message come in maya console, when software rendering rendering via hardware:

warning: unable opengl visual stereo buffer, trying without //.

video card nvidia geforce gtx 260m. using nvidia driver version: 195.36.24 . running glxgears works no jittery results. however, when run "glxgears -stereo" in same command line, following error:
error: couldn't rgb, double-buffered, stereo visual

no idea how might solved. did check xorg.conf file , reads:

code:
# nvidia-xconfig: x configuration file generated nvidia-xconfig  # nvidia-xconfig:  version 1.0  (buildmeister@builder58)  thu apr 22 20:35:23 pdt 2010    section "serverlayout"      identifier     "layout0"      screen      0  "screen0"      inputdevice    "keyboard0" "corekeyboard"      inputdevice    "mouse0" "corepointer"  endsection    section "files"  endsection    section "inputdevice"      # generated default      identifier     "mouse0"      driver         "mouse"      option         "protocol" "auto"      option         "device" "/dev/psaux"      option         "emulate3buttons" "no"      option         "zaxismapping" "4 5"  endsection    section "inputdevice"      # generated default      identifier     "keyboard0"      driver         "kbd"  endsection    section "monitor"      identifier     "monitor0"      vendorname     "unknown"      modelname      "unknown"      horizsync       28.0 - 33.0      vertrefresh     43.0 - 72.0      option         "dpms"  endsection    section "device"      identifier     "device0"      driver         "nvidia"      vendorname     "nvidia corporation"  endsection    section "screen"      identifier     "screen0"      device         "device0"      monitor        "monitor0"      defaultdepth    24      subsection     "display"          depth       24      endsubsection  endsection    section "extensions"      option         "composite" "disable"  endsection
any ideas might problem? far, last 3 new editions of nvidia driver dont seem solve issue know gotta go beyond that.

i thought needed quadro stereo quad buffer - saying used able on geforce!? if so, happened nvidia got wise , disabled in geforce driver.

there's stereo mode option can set in xorg.conf:

, scroll down section on stereo

try
code:
option "stereo" "4"
in "device" section, or other numbers different stereo modes.

how to devide a circle into equal parts

how devide circle equal parts reggie,   depending on version, may able use free divide (length) script available here, setting number,   http://park12.wakwak.com/~shp/lc/et/en_aics_script.html   or may (smart guides friends):   1) use polar grid tool right size of circle, 0 concentric dividers , desired number of radial dividers, , ungroup; 2) extend radial dividers; 3) select circle , use scissors tool @ intersections (smart guides intersect ), may need select remaining parts underway.   or may (smart guides friends):   1) create vertical line through top , bottom (or left , right) anchor points line tool; 2) rotate copies @ relevant angles (to half number of cuts division); 3) select circle , use scissors tool @ intersections (smart guides intersect ), may need select remaining parts underway.
