Abstract
This paper presents an efficient BSpline surface reconstruction technique for modelling deformable objects. The differences of our methods from previous BSpline fitting approaches are: 1) the reconstructed BSpline patch does not need to be square shaped. This significantly reduces the required number of BSpline patches for reconstruction; 2) the dataset to be reconstructed does not have to be grid data. This is important, especially for 3D scan data, which is unstructured dense point cloud, normally with holes. A compact 3D shape description can be obtained using our approach. This shape representation allows 3D metamorphosis, direct manipulation of free-form deformation, and level of detail control (real time multi-resolution rendering). The demonstrated results are reconstructed directly from the dense point clouds collected from our 3D scanner (based on stereo photogrammetry technique) and example datasets provided by Cyberware.
