Optional
constantThe constant water droplet diameter for the Henyey-Greenstein + Draine phase function.
If useConstantDropletDiameter is false, this parameter is ignored.
Defaults to 3.4;
Optional
useIf this is true, a constant droplet diameter will be used throughout the atmosphere renderer's lifetime. Otherwise, the diameter is set dynamically each frame using Mie.phaseParam.
Defaults to true.
Parameters for the Henyey-Greenstein + Draine (https://research.nvidia.com/labs/rtr/approximate-mie/) approximation of the Mie phase function
