Currently, several frameworks exist for volume rendering that support the design of (multi-dimensional) TFs. In this project, we would like to investigate the potential of all available open source frameworks with regard to volume rendering and TF functionality, and to evaluate these frameworks in respect to challenging application domains, such as medicine and life sciences. This includes, but is not limited to rendering of volumetric microscopy data, ultrasound data and multi-modal, multi-scale and/or time dependent 3D imaging data. The project is conducted together with Dr. Katja Bühler from the VRVis Research Center. Upon successful completion of the project, there is potential of remuneration.
