Adjustable speed surface subdivision
We introduce a non-uniform subdivision algorithm that partitions the neighborhood of an extraordinary point in the ratio σ : 1 − σ, where σ ∈ (0, 1). We call σ the speed of the non-uniform subdivision and verify C continuity of the limit surface. For σ = 1/2, the Catmull-Clark limit surface is recovered. Other speeds are useful to vary the relative width of the polynomial spline rings generated...
متن کاملSubdivision surface watermarking
This paper presents a robust non-blind watermarking scheme for subdivision surfaces. The algorithm works in the frequency domain, by modulating spectral coefficients of the subdivision control mesh. The compactness of the watermarking support (a coarse control mesh) has led us to optimize the trade-off between watermarking redundancy (which ensures robustness) and imperceptibility by introducin...
متن کاملSubdivision Surface Simplification
A modified quadric error metric (QEM) for simplification of Loop subdivision surfaces is presented. The suggested error metric not only measures the geometric difference but also controls the smoothness and well-shapedness of the triangles that result from the decimation process. Minimizing the error with respect to the original limit surface, our method allows for drastic simplification of Loo...
متن کاملSubdivision-Based Surface Representations
Subdivision can be thought of as a natural extension of existing patch-based surface representations. In this view, subdivision algorithms effectively bridge the gap between patchbased and polygonal mesh representations. Using subdivision also naturally leads to useful multiresolution representations of surfaces. Such representations can be used for a variety of applications, most importantly, ...
متن کاملImplementing Subdivision Surface Theory
In my previous article "Subdivision Surface Theory" , I explained what subdivision surfaces were and why game developers should be interested in them. I also covered a couple different kinds of subdivision surfaces in their mathematical forms and briefly discussed their benefits and detriments. Most everything was in English, and the rest was expressed using equations. There were no code listin...
