The  Project |

The term volume graphics refers to
the visualization of static 3D scalar fields, as they arise from
measurement (computed tomography, magnet resonance imaging)
and simulation. The interpretation of such data fields is considerably difficult
due to their intrinsic complexity. |
In recent
years the value of direct volume rendering techniques for the
visualization of 3D scalar fields has become evident in many
application areas ranging from medicine and natural science to
computational science and engineering. The applicability of high
quality volume rendering, however, was mainly restricted to
expensive special purpose hardware or dedicated workstations with
high-end graphics subsystem and high-speed memory
bus.
Nowadays,
every consumer graphics board provides hardware support for 2D- and
3D-texture mapping. The texturing subsystem of these boards allows
bilinear interpolation of texture samples. Since interpolation
contributes a significant part to the computational cost of volume
rendering, it is desirable to exploit the available hardware
features for acceleration. | |

| The
OpenQVis project implements methods for interactive high-quality
volume visualization on general purpose hard-ware such as commodity
desktop computers with graphics cards designed for computer games
and multimedia. The aim of this project is to achieve high image
quality comparable to traditional ray-casting solutions at
interactive frame rates on inexpensive hardware platforms.
Based on collaborative research projects of the Computer
Graphics Group of the University of Erlangen Nuremberg
and the VIS Group at the University of Stuttgart, Germany,
efficient volume rendering techniques have been developed, targeting
the advanced features of modern PC graphics boards such as
multi-stage rasterization, pixel shaders and dependent texture
lookup.
