How to create and use noise_filter_path for both rain and snow.

[ralflizard]

Hi,

After reviewing the code, I haven't been able to replicate the creation and use of noise_filter_path for the rain and snow functions.

I was able to run the code for both using the DistributionRanges option, but it doesn't really account for existing high density area points in the point cloud which leads to points existing in areas that shouldn't. I'm trying to generate noise filters that take into account these high density areas to avoid generating rain/snow there but haven't figured out the correct way to name the files so the underlying code picks it up.

Can you provide examples of the noise filter file generation and the naming of each?

Thank you.

You can use one of the correct function overload for rain/snow and a noise filter will be generated as part of that function call as can bee seen here. The documentation further describes the parameters for that.
The available distributions are also in the documentation.

The alternative would be a path to the directory containing the npz file. The filename should be nf_N=<n>_R=<r>.npz, where
<n> and <r> are randomly generated based on num_drops_sigma (n) and precipitation_sigma (r) to pick between multiple files.
I unfortunately don't have an example for that right now but the implementation can be found here.

I apologise for the late reply and I hope that helped!
