Jan 17	revised	Is there a global “low resolution” filter for OpenGL? added 154 characters in body
Jan 17	answered	Is there a global “low resolution” filter for OpenGL?
Jan 16	comment	*Retrieve the coordinates of the occluding* (closest/drawn) pixels during 3D overlap, using OpenGL?** Sounds like a problem which could be solved using BSP. I could think of a couple of ways to get the overlapped pixels (using stencil or alpha), but getting back to 3d would be a hassle. With BSP you should be able to calculate the actual overlapping geometry.
Jan 15	comment	OpenGL 3 and the Radeon HD 4850x2 The nVidia and ATI compilers have been notoriously different in the way they accept some small nuances of glsl. Be sure to check any compilation and linking logs.

Jan 14	comment	Is it reasonable to write a game engine in C? C can be understood by mere mortals. C++ seems to have lots of features and edge cases seasoned programmers learn about even after a decade of using it every day for living.
Jan 14	comment	How to go about getting hired by a game company I'd add a fine point, not only make games, but finish your projects. Surprisingly many people have a portfolio of lots of half-finished thingies. Finished projects are much more valuable, even if you have a feeling you want to move on to your next fun idea.

Jan 14	comment	What is the difference between OpenGL ES and OpenGL? ES isn't a straight subset of OpenGL, so your claim that all ES apps work on non ES systems isn't true.
Jan 14	comment	Can you sync screen update on vertical retrace with OpenGL? SDL's swapbuffers won't do anything magical if you set your driver settings never to do vsync.
Jan 14	answered	Custom mesh format - yea or nay?
Jan 14	comment	Changing Palette for Day/Light Mode using GIMP From a glance, it seems like the images are more or less monochromatic, with one using a color ramp tinted to red and the other tinted to blue. So, I'd store the image as greyscale and alter the palette accordingly at runtime.
Jan 14	answered	OpenGL's matrix stack vs Hand multiplying
Jan 14	comment	Make Pong on android using OpenGL-ES Possibly because it looks like homework.

Jan 13	comment	*What is the contents of the buffer after* a call to glSwapBuffers()?** Ok. The only reference I can give, however, is my own experience. I shall be more careful.
Jan 13	comment	*What is the contents of the buffer after* a call to glSwapBuffers()?** Wow, negative votes. I'm serious about what I wrote about though - especially if you're writing for mobile hardware, be sure to include that clear there.
Jan 13	comment	Does swf provide better compress rate than zlib for png image? As a note, the compression algorithm used by PNG is actually zlib. png might include some filtering that causes zlib to compress better than just zipping up the raw bitmap though.
