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.
The Visible Ear Simulator website is available. Download of the free-ware version will be available soon: http://www.alexandra.dk/ves/
This post will try to explain how to implement a GPU based raycasting render, using open GL and Nvidia’s CG. This tutorial assumes some experiance with OpenGl and vertex-fragment shaders. First of all why do we need this algortihm? Because it is a smart way to achieve high quality volume rendering and the raycasting algorithm is well suited for the modern GPU’s. Esspecially the new 8800 series because of the unified shading system. The reason behind this tutorial is to…
