In this paper, we propose a novel 3D B-Spline surface reconstruction technique for 3D metamorphosis for animation and entertainment.
The approach allows one-to-one mapping between the object space and a parameter space, and therefore automatic correspondence
between a pair of reconstructed objects. B-Spline-based shape representation also has the a...

... A ( s ) [ Q 0, g ( s ), Q 1, g ( s ), L , Q n , g ( s )] . f and l are shape descriptors of curve F and L , respectively. Shape descriptors have several important properties, including: • One-to-one mapping from the parameter domain to the object space. For each pair of parameter value ( s , t ) , there is a unique corresponding B-Spline surface point in the object space. • Compact representation for 3D objects. Over 90% compression rate is achieved and similar rendering result to that using original polygon representation. Figures 1, 2, 3 demonstrate some reconstructed B-Spline surfaces using our approach discussed above. For comparison, we also applied a previous B-Spline reconstruction method [5] on the same dataset in Figure 3. Rendered single patch B-Spline surface is shown in Fig. 2 ...

In this paper, we propose a framework for modeling and deforming heterogeneous volumetric objects defined as point sets with attributes. We propose to use constructive hypervolume objects, where the function representation (FRep) is used as the basic model for both object geometry and attributes represented independently using real-valued scalar fu...
