Here is a tech demo of our Cuda smoke visualizer software. The software demonstrates real-time interaction and visualization with a smoke data set. It is possible to adjust several parameters such as density and lighting position. To download press HERE.

Fun with Photonmapping

Photon mapping

Our first attempt to use photonmapping in our Cuda raytracer, 300 samples pr pixel, 1200×800, final image rendering time 65 secs.

Here is the famous sponza scene in a 400 pixel pr sample rendering, without and with photonmapping. At this moment this takes a few minutes

to render, but we hope to improve on the rendering time when we learn a little more about CUDA.

Ray marching smoke

Nice real-time smoke visualization, rendered by our CUDA tracer including a clear sky model. The smoke dataset was delivered by Michael Bang and Brian Bunch Christensen from the Department of Computer Science, University of Aarhus.
