Integrating Dynamic Deformations into Interactive Volume Visualization
Non-linear geometric deformation (or warping) is a useful tool for working with volumes. Unfortunately, the computational
expense of performing the resampling needed to implement volume deformation has precluded its use
in interactive applications. In this paper, we show how non-linear deformations can be integrated into interactive
volume visualization allowing for dynamic deformations to be used along with interactive viewing, exploration,
and manipulation tools. We describe how hardware assisted volume rendering can be adapted to resample volume
deformations, leveraging programmable shaders to compute deformations and the local coordinate transformations
required for shading effects. We describe how volume interaction techniques, such as ray picking and plane
slicing, can be used in concert with our deformation methods. Our methods extend to simultaneous display of
multiple volumes enabling comparisons. We demonstrate dynamic volume deformation at interactive rates on
commodity hardware for interactive deformation control, animated deformations, and volume widgets.
