[X3D-Ecosystem] Gaussian Splat data (from Aaron) negative scale data

[Bergstrom, Aaron]

That could be, I didn’t look at the raw files. I saved what SuperSplat generated.

However, I provided the same files to the AOUSD emerging geometries group, and the feedback was positive.

Subject: Gaussian Splat data (from Aaron) negative scale data

I looked again at the gaussian splat data from Aaron, and I discovered that there were negative scale values!' Ouch.

That might mean that the file is corrupted, my reader is bad, or negative scales are normal,

If anyone is looking at the data from the PLY files, can they confirm or deny?

Thanks,

John

Don had a cool way of sorting Points into PointSets by scale, but if we can't get the right scale, that's going to be problematic.
