Occlusion culling technique at its best.
A lot of new technologies were showcased at this year’s GDC. From ray tracing tech to new APIs, the event was the best in years. But if I have to point out one game developer who are pushing video game graphics to an all together different level, then it has to be CDProjekt. The Witcher 3: Wild Hunt looks absolutely phenomenal and it wouldn’t have been possible without Umbra 3, a software that specializes in providing occlusion culling solutions to video game developers.
During GDC, Przemyslaw Czatrowski, Engine Programmer at CD Projekt RED and Jasin Bushnaief, Lead Programmer at Umbra Software gave almost an hour long presentation about Umbra 3. You can check out the entire presentation here or see a small snippet above.The video shows how CDProjekt have integrated Umbra 3 into their game engine, RedEngine 3, which has resulted into reduced memory usage and query times.
