The point cloud is actually the vertices of the mesh from RC. As for textured model, here is the upper section. https://skfb.ly/KUE9. If you have blurry, stretched parts of a model it’s due to misalignment and /or incorrect distortion parameters. For image sequences with small intervals between shots the results usually optimise quite easily but when you get more complex geometry and multiple camera paths things can go wrong.
I’ve processed a few building shot with a GoPro and everything worked fine but a larger, more complex building shot with the same camera exhibited weird “ghosting” of misaligned components due to incorrect distortion parameters. This was largely due to the selection of camera paths by the pilot not suiting the algorithms used by RC. Using the process I described here, I got it to align nicely as well as could be expected with just 2 alignments, and had a complete model after adding a few CPs to join the 2 components produced.
I generally don’t get “blurry areas” any larger than the blurry areas seen in the sketchfab model you posted, which is fine if it’s a model of grass or rocks, but when it’s a detailed frescoed or painted interior or vault, they are quite noticeable. Unfortunately, I think it’s just a part of the stretching and blending that both Photoscan and RealityCapture do to the photos when they make the texture.
