ply2vrmesh limits ?

[raxto]

thank you guys, now i can convert 618M poly from ply to vrmesh in 27min and then render it to 40.000x40.000 [1.6Gpix] in 18min on renderfarm and it not takes more than 10GB RAM.

What are you rendering? These are some serious numbers.

Hi Vlado,

it's a vertex colored mesh of building created from combination of laser scans data and photogrammetry and we doing some hires ortho renders for architects.

Hi, very similar problem again, maybe same.

I tested it with two versions, both same result 1kb vrmesh.
I am sending ply file to support @ chaosgroup.com, this time it's 5.5 MB zipped only.

first version tested:

I tested it, but maybe new bug there, i am sending new file again at support.
When i import generated vrmesh file from file i sended to support to maya, it again fill-up RAM and crash.

Thank you very much for the files.
We'll update you when we have some news about it.

Nice, it's working ! thx

Btw. i have new problem, some time ago we reached near 2³² limit,
and we will go over soon.

[vlado]

The limit if 2^32 what? Triangles?

Best regards,

Hi vlado,

little mistake, our latest mesh was 2.030.399.206 triangles.
We are now at 2³¹, with actual ply2vrmesh we can go at 2³², right ?

Best regards,
Rasto

[vlado]

It looks like 2^31 is a limit right now. We can extend this to 2^32 relatively easy, if you need it. It should not be too hard to do even more. However would it not make sense to split the geometry into several .ply files instead? It might be easier to manage things.

Best regards,
Vlado

[raxto]

Our mesh with 2.030.399.206 triangles was imported into Maya in 3399 vrmesh parts. It's was about 1.5M per part.
Ok, if we will stay in this workflow, we maybe don't reach the limit, but who knows.

btw. vlado, we are now using vertex colors, we wana try to use textures and do some tests, is there some news with this thread ?

Hi Vlado, here is preview model, it's about 500M poly:
