Fast Catmull-Rom Spline Interpolation for High-Quality Texture Sampling
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
It is well known that cubic texture filtering can be efficiently implemented on the GPU by using a method published by Sigg and Hadwiger [SH05], which simplifies the evaluation to a linear combination of linear texture ...
Cosine-Weighted B-Spline Interpolation on the Face-Centered Cubic Lattice
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Cosine-Weighted B-spline (CWB) interpolation [Csé13] has been originally proposed for volumetric data sampled on the Body-Centered Cubic (BCC) lattice. The BCC lattice is well known to be optimal for sampling isotropically ...
