Direct Visualization of Deformation in Volumes

Stef Busking, Charl P. Botha, and Frits H. Post

Enhancing the visualization with texture reveals various properties of the deformation field, such as a rotational component in this synthetic saddle point deformation (1283 ). Colors in the last two figures go from blue (low) to orange (high).

Deformation is a topic of interest in many disciplines. In particular in medical research, deformations of surfaces and even entire volumetric structures are of interest. Clear visualization of such deformations can lead to important insight into growth processes and progression of disease. We present new techniques for direct focus+context visualization of deformation fields representing transformations between pairs of volumetric datasets. Typically, such fields are computed by performing a non-rigid registration between two data volumes. Our visualization is based on direct volumerendering and uses the GPU to compute and interactively visualize features of these deformation fields in real-time. We integrate visualization of the deformation field with visualization of the scalar volume affected by the deformations. Furthermore, we present a novel use of texturing in volume rendered visualizations to show additional properties of the vector field on surfaces in the volume.
