OpenQVis released on Sourceforge!
OpenQVis is a GPL project for the visualization of 3D volume data on rectilinear grids, as they arise from tomographic measurement and simulation in computational science and engineering. It uses QT and OpenInventor/Coin3D to achieve cross-platform compability. OpenQVis is available for Linux, Windows 98/ME, Windows NT/2000/XP and SGI IRIX. It has been successfully compiled on HPUX. I am currently working on a MacOSX 10.2 build.

Software
Updated Pre-Integrated Volume Renderer to Version 2.1. The renderer now also supports ATi's Radeon8500 graphics card by employing the fragment shader OpenGL extension. On GeForce3-based cards the texture shader and register combiner extensions are used.
Download the new version from the Pre-Integrated Volume Renderer Homepage.

Presentation
A new talk with the title "Using Flexible Rasterization Hardware for Interactive High-Quality Volume Rendering" is now online. The talk was given on 8th of November on the Graphiktag 2001 in Tuebingen. Download the talk via this link (Powerpoint Slides 13.6 MB).

Presentation
Our paper "High-Quality Pre-Integrated Volume Rendering Using Hardware-Accelerated Pixel Shading" has won the "best paper award" on the Siggraph/Eurographics Workshop on Graphics Hardware 2001. The talk is now available for download here.

Research
We have developed a novel texture-based volume rendering approach that achieves the image quality of the best post-shading approaches with far less slices, called Pre-Integrated Volume Rendering. Find details here.

Dr. Bernd Tomandl and me at booth #9305 on RSNA 2000 in Chicago. We showed high-quality direct volume rendering on low-cost desktop PCs using remote visualization and local GForce-based rendering. The remote rendering was done using a SGI Octane MXE located in Stuttgart/Germany.

- Download (14,6 MB)and unzip into the multi-texture demo directory. 
- Then run shell script runme_bob.sh (Linux) or runme_bob.bat (Windows)
- Press "Play" button
Warning: requires a lot of main memory (at least 256 MB recommended)
Hint: Try Isosurface mode for nice effects.

Poster
We'll be giving a talk and exhibition on this years RSNA conference in Chicago (26. Nov. 2000 - 01 Dec. 2000). These are the posters that we show at the exhibition at space no. 9305. We will also give live demos on remote and GForce-based volume visualization.
