Mesh imperfections
« on: September 02, 2016, 04:26:34 PM »
Hi there,

I've been doing some work in Photoscan recently and started noticing 'imperfections' in the form of a number of overlapping faces on the meshes. I've attached an image showing what I mean. I'm using a typical workflow so I doubt it's anything I've introduced. Meshes generated will often have tens, possibly hundreds of these overlapping, dodgy tri's.

The problem is that it then causes issues when viewed in shaded mode, and later in rendering too. This means I have to export into another package and retop or fix the offending parts of the mesh, reimport into Photoscan and recalculate textures.

I've not experienced or noticed this before so I assume it's a bug, though I'd like if someone could clarify/corroborate this?

Cheers

Alexey Pasumansky

Hello rocklobster,

Which version of PhotoScan you are using and do you see any problems mentioned in Tools Menu -> View mesh statistics dialog?
Best regards,

Apologies for the long delay, I've been out of office since the original post.

I was using the latest version available for download, and the minor version before that to build the meshes in the original project. I updated with the hope that it would address these mesh issues but it didn't help.

I will look at the diagnostics dialogue tomorrow to see if anything appears. I also tried building with and without OpenCL enabled but that didn't help either.
