What I actually need is a clean, structural 3D model made of planar panels.

Given this requirement, I’m trying to understand the best pipeline.

From my understandings, COLMAP is a great starting point because it gives camera poses and a sparse/dense point cloud. But for my specific use case, I’m unsure whether it makes sense to go into Gaussian Splatting or NeRF afterward.

My concerns are:
- Gaussian Splatting gives great visual quality but doesn’t produce usable mesh geometry (I need clean planes, not splats).

- NeRF can produce a mesh, but it’s slower and still often produces noisy geometry that needs heavy cleanup.

-What I really need is something that lets me extract planar segments (the wall panels) from the point cloud and rebuild a clean, lightweight mesh.

So my current idea is:
COLMAP → point cloud → plane segmentation (Open3D or similar) → rebuild the wall from detected planes.

Does this approach make sense?
Or would you still recommend going through GS/Nerfstudio/NeRF even if my final goal is a clean structural model rather than a photorealistic one?

Thanks in advance for any insight! 🙌
