We present a novel visualization framework that unifies the models from DTI and HARDI, using a classification scheme for model selection. The data is represented by diffusion tensors or fibers in the Gaussian and HARDI glyphs in the non-Gaussian areas. We exploit the capabilities of modern GPU to optimize the rendering performance and visual quality of the glyphs. All of the visualization parameters are controlled by the user in real time. Different color coding on the glyphs enhance the anisotropy information or highlight maxima. This is the first attempt to give fast and intuitive insight into the complex HARDI data.
