Python S3O module and optimizer

[Muon]

Suggestions to handle these cases? Perhaps a lower limit on the number of vertices before it decides to optimize.

[Beherith]

Yeah, don't optimize under 16 vertices. The gain negligible there anyway.

[Muon]

Hm. Is there perhaps any more reliable way of detecting this? Optimizing 16-vertex meshes would still be a performance improvement if they were drawn often.

I tried it on XTA, since it uses Mr D's core vehicle models, and the result was only 2 or 3 files out of ~20 got optimized. When I tested the performance of those optimized units, there was no FPS gain and I was even sure that in case of CORE Cloakable fusion power plant I saw a FPS reduction.

Ask Nemo what he did when fixing the issue in S44, it was something trivial afaik.

Hm, I should probably make the decision whether or not to save the optimized S3O depending on whether or not the ACMR goes down, rather than file size.

EDIT: Okay, updated. Now it commits anyway, because it may have optimized drawing regardless of the change in file size. I should point out that the vertex cache optimizer only works on triangles, but not quads or tri strips.

EDIT EDIT: I've run the optimizer on that model, and the ACMR goes from 2.009901 to 0.982673, which means it *should* yield a performance improvement.

I would say anything under 4 vertices can definitely be left unoptimized.
Btw I use your s3olib extensively. Its super nice and well built!

Anything you could contribute back to the repo?

In what quantum reality is Upspring reliable?

Upspring 1.54 is very reliable. It has it's quirks, but it is more or less rock solid. I have far more trouble with spring doing stupid shit to models than upspring.
