Separate RNG states are used for the following sampling domains during
|
| 22 |
photon distribution:
|
| 23 |
|
| 24 |
- source partition
|
| 25 |
- emission direction
|
| 26 |
- emission counter fraction
|
| 27 |
- mean free distance in medium
|
| 28 |
- scattering direction
|
| 29 |
- russian roulette.
|
| 30 |
|
| 31 |
In addition, each photon map also has a local state randState used for
|
| 32 |
distribRatio during distribution and for bias compensation during
|
| 33 |
gathering.
|
| 34 |
|
| 35 |
The random seed randSeed can be added to each initial state with
|
| 36 |
pmapSeed() so the RNGs can be externally seeded if necessary.
