Exported PLY is mirrored #133
Description
I noticed in Unity, the GuassianSplats object has a scale of "1, 1, -1", ie in the Z it has a negative scale.
However in Unity the splat displays correctly.
If I export the PLY from Unity, and load it into any other viewer, the result is mirrorer. This must be due to the -1 negative Z scale, however if I remove the negative scale in Unity, then in Unity it displays mirrored and its harder to line things up to other things. This does fix the mirror in loading the PLY back into other viewers, but if I set the origin to somewhere specific for example, then because thigns get mirrored, it no longer lines up.
I also dont know if this is messing up the Spherical Harmonics....
