Category: mesa-core Group: Rendering Error >Status: Closed >Resolution: Out of Date Priority: 5 Submitted By: Sheila Santos (sheila_santos) Assigned to: Nobody/Anonymous (nobody) Summary: osmesa 64 bit problem with gl display lists using glMaterial Initial Comment: We are using osmesa, mesa version 6.0.1, for our software renderer on both 32 bit Intel Xeon machines and 64 bit AMD Opteron machines. I have found a potential 64 bit problem in the gl display list code when defining object material properties. Our code looks something like: glNewList( 1, GL_COMPILE ); glMaterialfv( GL_FRONT, GL_SPECULAR, specularVal ); glMaterialf( GL_FRONT, GL_SHININESS, shininessVal ); glMaterialfv( GL_FRONT, GL_AMBIENT, ambientVal ); glMaterialfv( GL_FRONT, GL_DIFFUSE, diffuseVal ); glEndList(); Later on we excute the list when drawing the polygons. This works fine on 32 bit builds, but on 64 bit builds my polygons are not visible. If I hardcode the glMaterial calls in place of executing the display lists, the 64 bit build behaves as the 32 bit build - polygons visible and properly shaded. This may point to a 64 bit issue in the glMaterial/glDisplayList code for osmesa. Thanks for looking into this. ---------------------------------------------------------------------- >Comment By: Brian Paul (brianp) Date: 2006-05-10 08:56 Message: Logged In: YES user_id=983 I assume 6.4.2 works for you.

I'll try upgrading to 6.2.1 and writing a test app that reproduces the problem. ---------------------------------------------------------------------- Comment By: Brian Paul (brianp) Date: 2005-05-07 10:27 Message: Logged In: YES user_id=983 What OS are you working on? There have been recent check-ins for fixing some 64-bit Windows issues. Otherwise, I'd suggest trying a more recent version of Mesa, such as 6.2.1. Finally, if you could provide a small test program to reproduce the problem, I could run it on 64-bit Linux and see what happens. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100003&aid=1196677&group_id=3 ------------------------------------------------------- Using Tomcat but need to do more?
