...
- It can compute single scattering effect in addition to multiple scattering.
- It doesn't need any pre-computation and works well with IPR.
- It is easier to get light blockers inside geometry to have interesting volume shadowing effects.
- It has a smaller memory footprint.
- It works well on scenes of large scales - a big problem in the point-based version.
- Apart from sampling noise at lower sample counts, the The overall look is very close to the point-based version and can be used as a drop-in replacement.The semantics are almost exactly the same
Cons of Ray Tracing SSS
- At lower sampling counts it produces more sampling noise than the point-based version.
