Detailed Description
template<Size D>
class LutKernel< D >
A look-up table approximation of the kernel.
Can be constructed from any SPH kernel. Use this class exclusively for any high-performance computations, it is always faster than using kernel functions directly (except for trivial kerneles, such as TriangleKernel). The precision difference is about 1.e-6.
