Quick Review – GPU Caps Viewer
GPU Caps Viewer is the new I worked on these last days. It’s the successor of HardwareInfos. GPU Caps Viewer is based on the branch v3.x of the oZone3D engine (while HardwareInfos is an oZone3D v.2.x branch based tool). In … Continue reading

NVIDIA OpenGL Extension Specifications
Finally NVIDIA releases the specs of the new OpenGL extensions that come with the gf8800. Great news! :thumbup: These specs are very important for us, poor graphics developers, in order to update our software with the latest cool features. So … Continue reading
Soft Shadows are Great!
I’ve just finihed to implement soft-shadows in the new oZone3D Engine. And I must say that soft shadows bring a huge amount of realism and credibility to 3d scenes. See for yourself: The oZone3D tech demo is available here: Soft … Continue reading
ATI and Depth Map Filtering
I’ve just found in the super paper of ATI, called “ATI OpenGL Programming and Optimization Guide” that all ATI GPUs from the R300 (Radeon 9700) to the latest R580 (Radeon X1900) only support NEAREST (and the mipmap version) filtering for … Continue reading
Depth Map Filtering – ATI vs NVIDIA
Really ATI has some problems with OpenGL. Now I’m working on soft shadows and my tmp devstation has a Radeon X700 (not the top-notch I know but an enough powerful CG). With my X700 (Catalyst 6.6) the soft shadow edges … Continue reading
NPOT Textures
It’s nice to come back to code! I’m currently working on a new and simple framework for my OpenGL experimentations before implementing the algorithms in the oZone3D Engine . RaptorGL is a little bit too heavy for simple tests so … Continue reading
