------- Comment #2 from [EMAIL PROTECTED] 2007-07-13 07:43 PST ------- Mesa is generating a GL_INVALID_OPERATION in glDrawPixels() when drawing GL_DEPTH_COMPONENT pixels when there's no depth buffer (if you set MESA_DEBUG=1 you'll see the error message). So, the glDrawPixels is a no-op. Now, the GL spec says that drawing GL_STENCIL_INDEX values to a non-existant stencil buffer generates GL_INVALID_OPERATION, but it doesn't say that about depth pixels. I just tried NVIDIA's driver and they generate an error just like Mesa for the GL_DEPTH_COMPONENT case. I guess I should change Mesa to follow the spec, but it's kind of a corner case. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
