Document lod format

[tomasparks]

Can the sog octree/lod format be document?

[slimbuck]

Once we're satisfied the format is stable we definitely will!

I'm a bit confused about the actual functionality. Can splat-transform generate lods from a single input splat or do we need to generate the separate lods ourselves?

[slimbuck]

For now you must provide the separate lods yourself.

We may work on an automatic decimator for generating the lods in future, but so far we've only seen much worse results from decimators compared to training (understandably, can't beat the trainer).

If you have an xgrids LCC file, these already have lods available and splat-transform can use those.

I just noticed README.TXT was missing the --lod action, I've just added it.

So to generate a streaming SOG dataset, you can do something like:

splat-transform ./lod0.ply -l 0 ./lod1.ply -l 1 ./lod2.ply -l 2 scenes/lod-meta.json

what if i have a environment.ply too, do i simply put it as the last one ?

You need to tag the environment with lod -1, but I see the CLI doesn't allow this. I will will fix this asap!
