If your only using the window management facilities (include context/core context creation) then using FreeGLUT and GLEW is completely sufficient. Do you need any of the fixed-function using FreeGLUT convenience functions?]]> Wed, 11 Jan 2012 23:36:46 PST texure mapping anti-alias http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=308031#Post308031 Posted by malexander:
Multisampling smooths out edges of geometry. I'm not sure what modes are available on iOS, but you need a framebuffer with multiple samples, or a multisample renderbuffer/texture with an FBO.

I'm not aware of any float performance issues (or lack of issues) with Intel, but I have confirmed that uploads to texture resources using GL_RGB10A2 are also stall-free, so it may be the case that the same applies to reads from an FBO (GL_RGB10A2 is]]> Tue, 22 Nov 2011 04:35:54 PST GLUT Window Starts out Minimized http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=302775#Post302775 Posted by Blakeasd:

No, I've traced the problem to how I'm deriving cStrings from Cocoa. I've got a separate loader in C++ that handles the files just fine. I was using a Cocoa setup until I had gotten SDL 1.3 to properly initialize OpenGL 3.2 for Lion, which I have jus]]> Wed, 31 Aug 2011 15:03:59 PDT So what do you guys think of Apple's 3.2 drivers? http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=301110#Post301110 Posted by JoshKlint:
