Low resolution of meshes? about cork HOT 5 OPEN

That's very strange. Can you tell me what order the coordinates your model uses are? Is it very far from the origin?

There is a slight quantization for the purposes of arithmetic, but it a should be at the 10^-6 scale relative to the largest coordinate value, so it should be unnoticable.

Hi,

After successfully compiling and running cork (Windows 7 64) I was quite surprised to see the very coarse resolution of the objects: in the screenshot the result for the sample geometry (difference of ballA.off and ballB.off) is shown. Is there a setting of grid size or samples I have missed? Similarly coarse results occur for other custom meshes, too.

Thanks and regards,
Matthias

Thanks for answering: actually, the depicted example uses the sample data included with cork (ballA|B.off). My own data is somewhat translated from the origin, but in the range of 50-150 units.

Ahh, I just noticed you're on Windows. In all likelihood there's something weird about how MPIR is being used that's breaking the code. This is very likely to be an arithmetic bug, so that's the obvious problem area.

Yes, only MeshLab was running on Mac. Any chance to narrow it down? MPIR seems no fun... Do you have a prebuilt test binary for windows available? Thx

Did you verify that MPIR is working? I don't have a test binary ready. I can try to poke around my windows box later.
