As of mid November the Soleil raytracer is capable of rendering animated scenes in realtime using a Bounding Interval Hierarchy, which is reconstructed every frame for models that have changed. For better performance this operation is performed lazily, which means that only the acceleration structure of models that are actually visible are updated. This video demonstrates a new water effect added to the raytracing demo I posted about the last time on October 7th 2007. It's based on artwork from Raven Software's Star Trek Voyager: Elite Force, so you might recognize the look of the scene (the map's name is 'Reservoir'). Performance drops compared to the purely static scene without water are negligible. Large portions of the video are rendered with activated 'Pixel Doubling'. This means that the scene is rendered at a resolution of 320x240 and subsequently streched to 640x480. Disabling 'Pixel Doubling' results in rendering taking place at the full resolution. The video was captured on 64-bit Ubuntu 7.10 running on a single AMD Athlon X2 3800+ at a resolution of 640x480 pixels.
