Surface Design Using Locally Interpolating Subdivision Schemes
نویسنده
چکیده
Non-uniform multivariate subdivision schemes are constructed, which generate limit functions interpolating some of the initial control points. Our schemes diier from the known interpolatory subdivision schemes, in that only some of the original control points are interpolated, and not the control points in every level. These new schemes are combinations of a non-interpolatory schemes with diierent local schemes near some of the original control points. They generate smooth surfaces interpolating given points, using stencils of small support. Next, it is shown how to modify known subdivision schemes so that the limit surfaces generated by them interpolate given normal vectors at given interpolation points.

Subdivision Schemes for Thin Plate Splines
Thin plate splines are a well known entity of geometric design. They are defined as the minimizer of a variational problem whose differential operators approximate a simple notion of bending energy. Therefore, thin plate splines approximate surfaces with minimal bending energy and they are widely considered as the standard “fair” surface model. Such surfaces are desired for many modeling and de...
متن کاملNormal Control using N-adic Subdivision Schemes
This paper presents simple and efficient deformation methods based on a new class of interpolating N-adic subdivision algorithms. Our N-adic scheme is a natural extension of a standard dyadic scheme – each face of the mesh is more generally divided into sub-faces – and geometric properties are similar. This framework enables us to locally deform the surface using different tools by either modif...
متن کاملSurface interpolation of meshes by geometric subdivision
Subdivision surfaces are generated by repeated approximation or interpolation from initial control meshes. In this paper two new nonlinear subdivision schemes, face based subdivision scheme and normal based subdivision scheme, are introduced for surface interpolation of triangular meshes. With a given coarse mesh more and more details will be added to the surface when the triangles have been sp...
متن کاملCombined subdivision schemes for the design of surfaces satisfying boundary conditions
We present a new kind of subdivision schemes, which we call combined subdivision schemes. Such schemes are used to reene a given control net, taking into consideration boundary conditions on the limit surface. Several schemes are presented that generate limit surfaces interpolating given boundary curves and cross boundary derivatives. The interpolated boundary curves are arbitrary parametric cu...
متن کاملInteractively Morphing Irregularly Shaped Images Employing Subdivision Techniques
The morphing or metamorphosis of images is often used to generate special effects in films and animation. In many cases only a part of an image will be affected by the morph, and often that part has an irregular shape. This work presents a new interactive technique for performing morphs based on locally interpolating subdivision surface schemes. The technique allows the definition of morph prob...
