My research is in shape modeling, the modeling and analysis of the shape of objects.
These shapes might be digital characters in a Pixar movie (see Wall-E),
buildings from the imagination of an architect (see Frank Gehry),
the latest automobile or aircraft design (see the Boeing 777, which was designed
digitally without physical prototypes),
anatomical models reconstructed from CT or MR images (see hip implants custom
designed for your femur),
or a precise representation of the scene in which a robot must plan motion
(see the Mercedes Benz factory floor).
Areas of current research interest include:
- morphometry
- shape alignment; registration of multiple shape models
- anatomical modeling for biomedical applications
- 3D urban maps
- mesh semantics
- tangent space analysis of smooth shapes, emphasizing dual representations
and the calculation of bitangency
- software suites for shape modeling
- reconstruction of meshes and smooth surfaces from point data
- reconstruction of meshes and smooth surfaces from curve data
- semantic mining of online image databases,
including canonical views and multiple view geometry
- visibility analysis of smooth scenes
- hulls and kernels of smooth shapes
- mesh data structures
- Bezier/B-spline/Hermite curves and surfaces
