Modern OpenGL presentation by Mark Kilgard (NVISION 08)

Wednesday, September 24, 2008 in Computer Graphics | No comments

NVIDIA has posted some OpenGL-related presentations from their recent NVISION 08 conference. I found the one on the GeForce 8 features and Cg particularly good with respect to introducing some modern OpenGL functionality and giving a sense of direction for the API.

Also check out the NVSG presentation with has some OpenGL related content.

ATI Catalyst™ 8.9 brings some OpenGL 3 extensions to Windows

Wednesday, September 17, 2008 in Computer Graphics | No comments

AMD has released ATI Catalyst™ 8.9, which includes a number of OpenGL 3 extensions:

  • ARB_half_float_pixel
  • ARB_draw_instanced
  • ARB_instanced_arrays
  • ARB_map_buffer_range
  • EXT_texture_compression_3dc
  • EXT_texture_compression_rgtc
  • EXT_texture_compression_latc
  • EXT_texture_shared_exponent
  • EXT_depth_buffer_float
  • EXT_gpu_shader4

The addition of the geometry instancing extensions and of gpu_shader4 (GLSL 1.20) is particularly significant, as they expose functionality that has been available since DirectX™ 9, and of course DirectX™ 10 features as well.

OpenGL extensions on Google Code

I just stumbled on this Google Code project which is categorizing and documenting OpenGL extensions. It should prove to be a very useful reference, check it out.

Forward-compatible OpenGL 3.0 constants

Sunday, September 7, 2008 in Computer Graphics | No comments

Michael Lucas-Smith posted on his blog a list of forward-compatible OpenGL 3.0 constants. This, combined with my list of forward-compatible OpenGL 3.0 entry points, should help people write future-proof OpenGL code.

Riven X and MPQKit Trac wikis back online

Tuesday, September 2, 2008 in Projects | 4 comments

The Riven X and MPQKit Trac wikis are finally back online. Although development has moved to Launchpad, the wikis still contain quite a bit of useful information, as well as milestone planning and open bugs. In particular, the MPQKit wiki has the MPQ format specification page, which is quite complete.
