This is part of the original method from "Volumetric Methods for Simulation and Rendering of Hair". The current filter is a simple box filter. Other energy-preserving filters such as gaussian filtering can be implemented later. The filter size is currently given as a cell count. This is not ideal, rather it should use a geometrical length value, but this is too abstract for proper artistical use. Eventually defining the whole grid in terms of spatial size might work better (possibly using an external object). |
