Abstract

This article presents uniform B-spline interpolation, completely con- tained 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 interpo- lation 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 that the cubic B-spline basis function can be evaluated in a short piece of GPU code without any conditional statements. Source code is available online.
