A General Scattering Phase Function for Inverse Rendering. (arXiv:2209.13875v1 [cs.CV])

We tackle the problem of modeling light scattering in homogeneous translucent
material and estimating its scattering parameters. A scattering phase function
is one of such parameters which affects the distribution of scattered
radiation. It is the most complex and challenging parameter to be modeled in
practice, and empirical phase functions are usually used. Empirical phase
functions (such as Henyey-Greenstein (HG) phase function or its modified ones)
are usually presented and limited to a specific range of scattering materials.
This limitation …
