Improving mesh quality?

Hi,

I’ve been playing around with RC for a week or so, but I’m having trouble getting a good looking mesh.

The point cloud looks quite detailed, but when it comes to building the high quality mesh it just looks really bad.

Example video export here:

The images used are 6k, so detail shouldn’t be a problem. I have even added a few control points on door edges etc to try and get better definition but doesn’t seem to help.

Any ideas?

Thanks.

Hi Nope
Looking on the video, is the room a synthetic 3D rendered scene or is it a REAL room ?
The main problem here is the “feature-less” subject, so white rooms, without any structure ( features to match ) are always problematic to do. For this sort of rooms is preferred to use a laser scanner and alternatively combine it with photogrammetry part to get good textures…

Yes, it’s a 3d model i’m trying to get working. Rather than baking textures and exporting multiple meshes to ue4 I am trying to get a single photogrammetry mesh that keeps the scene looking as much as the render as possible.

Is this just a bad example (mostly white interior), or is getting a clean mesh out of a rendered image pretty impossible? Or is an exterior a better choice to try out.

Would some sort of marker help Reality Capture produce something workable?

Thanks for your help.

Hi Nope
For this sort of workflow it is not good to use RC or photogrammetry in general, it is because you can solve this with other solutions and do not need to recalculate the models…
what sort of issues you have there ? in the texturing or in mesh output ? ( UE4 imports )

Hi Wishgranter,

It’s mainly down to the time and effort involved in baking textures for use in ue4 from 3dsmax. I would have to strip down the models to simplify, clean up the textures so they don’t have anything too complex, then bake the maps (and even with a renderfarm that takes time)

But using a photogrammetry method in a virtual scene, I was hoping I could get a far more streamlined approach (example attachment was done in 35 renders)
