Background

In this project we use GPU particle tracing to visualize 3D diffusion tensor fields. We can integrate and render about half a million particles at interactive rates, and we can select different visualization options like oriented particles of diffusion-dependent shape, stream lines or stream tubes. The proposed method provides an efficient and intuitive means to show the dynamics in diffusion tensor fields and it can thus be applied to explore the diffusion properties of biological tissue.
