Efficient GPU-Based Texture Interpolation using Uniform B-Splines
This article presents uniform B-spline interpolation, completely contained on the graphics processing unit (GPU). This implies that the CPU does not need to compute any lookup tables or B-spline basis functions. The cubic interpolation can be decomposed into several linear interpolations [Sigg and Hadwiger 05], which are hard-wired on the GPU and therefore very fast. Here it is demonstrated tha...
متن کاملGeometric Algorithm for Curve Interpolation with Non Uniform B-splines
The interpolation of a sequence of points is an important task in Engineering. In this work, three different interpolation methods are studied and expanded. The first method is the conventional interpolation Spline. The second method is a subdivision based geometric algorithm. The third method interpolates a given set of points with additional point normal constraints. The last two methods were...
متن کاملEfficient Cubic B-spline Image Interpolation on a GPU
Application of geometric transformation to images requires an interpolation step. When applied to image rotation, the presently most e cient GPU implementation for the cubic spline image interpolation still cost about 10 times as much as linear interpolation. This implementation involves two steps: a pre lter step performs a two-pass forward-backward recursive lter, then a cubic polynomial inte...
متن کاملHigh order interpolation and differentiation using B-splines
We present a methodology of high order accuracy that constructs in a systematic way functions which can be used for the accurate interpolation and differentiation of scattered data. The functions are based on linear combination of polynomials (herein B-splines are used). The technique is applied to one-dimensional datasets but can be extended as needed for multidimensional interpolation and dif...
متن کاملA Hole-filling Algorithm Using Non-uniform Rational B-splines
A three-dimensional (3D) geometric model obtained from a 3D device or other approaches is not necessarily watertight due to the presence of geometric deficiencies. These deficiencies must be repaired to create a valid surface mesh on the model as a preprocess of computational engineering analyses. This procedure has been a tedious and labor-intensive step, as there are many kinds of deficiencie...
