We are playing around with our CUDA ray tracing software. The design philosophy is to create a real-time ray tracing experience that allows the user to play with the visual parameters and get an instant feedback. This is not something revolutionary but ray tracing is such a flexible rendering technique, so the basic software can be used in a lot areas. In this demo the user can change and update the material properties at runtime. We finally found a decent…
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.
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.
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.
Today we presented the Onco visible man for the first time, at a workshop at Aarhus University hospital. The prototype features a real time stereo visualization of the “visible human” dataset. And the user is able to navigate, select and remove all the different segments of anatomy.
We have recently begun initial experiments and implementation of a GPU assisted raytracer (through CUDA). Our vision is a progressive global illumination renderer with real time updates.
