Carmack: Direct3D is now better than OpenGL

John Carmack, long time creator of such gamign classics as Wolfenstein, Doom, and Quake, dropped a bombshell on the graphics community in an interview with bit-tech where the announced his newly found favor for Direct3D over OpenGL. Speaking to bit-tech for a forthcoming Custom PC feature about the future of OpenGL in PC gaming, Carmack […]

Equalizer 1.0and Collage 1.0 Alpha now Available

Equalizer, the somewhat next-generation of the massive tiled display system Chromium, has just hit version 1.0 alpha and added a nice API and SDK system called ‘Collage’. The most notable new features in this release are: Full feature set and API of Equalizer 1.0 GPU compression plugins Failure tolerance during initialization Administrative API for runtime […]


Image Processing with OpenGL and Shaders

A great article in The Linux Journal discusses the creation of an OpenGL-based Image Processing system that can analyze video captured from an attached camera in real-time. This article discusses using OpenGL shaders to perform image processing. The images are obtained from a device using the Video4Linux 2 (V4L2) interface. Using horsepower from the graphics […]

Hierarchical-Z map based occlusion culling

Rastergrid is back with more details for their OpenGL4.0 Mountains demo, this time time they update the occlusion culling algorithm to utilitize the Hierarchical-Z buffer technology in new OpenGL4.0 spec. Occlusion culling is a visibility determination algorithm that is used to identify those objects that did reside in the view volume but still aren’t visible […]


OpenGL 4.0 Mountains demo released

Rastergrid has a new OpenGL 4.0 demo released that shows dynamically generated mountains, valleys, and trees all using algorithms in DirectX10 and OpenGL4.  They manage to do level of detail, culling, and and geometry instancing all on the GPU, leaving the CPU almost untouched. The result is a renderer that does little to no scene […]

More Insights into the OpenGL4.1, OpenGLES2.0, & WebGL Situation

Update 8/5: By request from Khronos, I’ve added all the little ™ and ® ‘s. Last week I posted a rather, well let’s just say “sensational”, article about the coincidental announcement by AMD/ATI of their new OpenGL|ES2.0 Driver for Desktops and Khronos’s announcement of the OpenGL® 4.1 spec which offers full backwards compatability with the […]


Khronos SIGGRAPH2010 BOF Presentations Online

If you couldn’t make it to the various Khronos BOF’s at SIGGRAPH on OpenGL, OpenCL, or COLLADA, then you can at least view the presentations online. There’s several to look at: OpenGL BOF: Ecosystem Update GLSL Overview Intro and Overview Jon Peddie Intro SPEC Update gDEBugger Update OpenCL BOF: AMD GREMEDY Intel Intro and Overview […]

AMD Releases Unneeded OpenGLES2.0 Desktop Driver

Update 8/3/2010: Read a followup to this post here. I just got a press release from Khronos about the first OpenGL ES2.0 driver for Desktop systems coming to market from AMD.  Upon further inspection, this looks a bit fishy. At SIGGRAPH 2010, AMD (NYSE: AMD) today announced availability of the first software driver for desktop […]
