摘要: The paper presents a splatting algorithm for volume rendering of curvilinear grids. A stochastic sampling technique called Poisson sphere/ellipsoid is employed to adaptively resample grid with set randomly distributed points whose energy support extents are well approximated by spheres and ellipsoids. Filter kernels corresponding these ellipsoids used generate the rendered image conventional footprint evaluation algorithm. Experimental results show that our approach can be regarded as an alternative existing fast techniques
