Abstract:
We present a powerful
morphing technique based on level set methods, that can be combined
with a variety of scan conversion/model processing techniques. Bringing
these techniques together creates a general morphing approach that allows a user
to morph a number of geometric model types in a single animation.
We have developed techniques for converting several types
of geometric models (polygonal meshes, CSG models and MRI scans)
into distance volumes, the volumetric representation required
by our level set morphing approach.
The combination of these two capabilities
allows a user to create a morphing sequence regardless of the model type
of the source and target objects, freeing him/her to use whatever model type
is appropriate for a particular animation.
