Automatic size and variance determination for better surface splatting quality on close-up view
Surface splatting has been proven to be a viable alternative to traditional polygon rendering for highly detailed models. In terms of rendering performance, surface splatting has surpassed polygon rendering when it fully exploits today's graphics processing units (GPU). However, in terms of rendering quality, surface splatting could still be inferior to polygon rendering when the model is viewed close-up and when the size and variance of each splat is not computed properly. In this paper, we present a method that improves the image quality of surface splatting to the level comparable to polygonal rendering by automatically finding a suitable size and variance for each splat.
