Hi Sir, thank you very much! May i ask what if i have some sample data of a building point cloud, but it has some open ends i think, making the mesh generate result has the warning: [Open3D WARNING] [SimpleShaderForTriangleMesh] Binding failed with empty triangle mesh. How could we overcome this? thank you!

Hmmm, the approach should work for any type of comple point clouds, therefore, it may be a good idea to investigate! You can reach me on learngeodata.eu, or in the discord channel and I will check out your dataset 😉

@moshuchitu203 5 ай бұрын

Maybe if the open ends are planar, with known shapes, maybe write a random point generator function will be sufficient?

Thanks, very interesting... Your point cloud voxelization to mesh approach is also very interesting, thanks 👌🏻👏🏻

do you think this procedure would also work well for less dense point clouds?

@FlorentPoux 11 ай бұрын

Yes it would! You just need to adjust the radius of your ball

Hi Sir, thank you for your videos and your effort I'm now working on a XYZ file format of a point cloud of neom area, and the file is about 500MB and also the file has the format of XYZ RGB and the Normals, but the normals are all zeros in all the rows. every time I run the code the kernal just dies, do you know the reason behind that? the file works fine in cloudcompare software but in the code does not as I said the normals are all zeros and the RGB values are between 0-255, and xyz just float numbers

Sir, is there any way to export the mesh as one of these files? I am trying to model in ABAQUS using point cloud data and am trying really hard to bridge the gap with an efficient process.... FILES: Nastran (.bdf, .dat, .nas) ANSYS (.cdb) STL (.stl)

@amartious2123 Жыл бұрын

Hello, at 4:25 you show that the Point Cloud you captured has proper normals. Hos did you get these? Did you estimate them after acquisition or were they computed during the capture? Actually, I'm really interested in learning about your capture method, and if it's possible to use a similar process for dynamic point clouds (volumetric video).

@FlorentPoux Жыл бұрын

Hey @amartious2123 ! These where computed afterwards, as the initial ones where not properly oriented. The capture method is Photogrammetry, so I will make a video on that to show my process to get such point clouds and 3D meshes! It is indeed possible to capture dynamic point clouds, but the data volume will be on par :)!

Thanks! You have some ways but it is a bit broken (you have to compile from scratch). I would advise getting to work with an isolated environment with Python 3.9

Hey paul! I will make a video on installing open3d with conda then (else I recomment pip: pip install open3D), as with the new version it looks like they do not have ithe possibility with conda.

Thanks! Yes indeed, but then you would have to transfer the vertex colors to the faces, which will a bitdegrade the quality of the texture. I will make another episode on point cloud meshing with texture creation

If we don't have normals, how can we compute them? I use pcd.estimate_normals(search_param=o3d.geometry.KDTreeSearchParamHybrid(radius=0.1, max_nn=30)), but the result is very bad

@FlorentPoux 10 ай бұрын

If you do not have normals, then, an approach like morphological deformation is better suited. I will do a video on it, on how to avoid computing normals. But maybe your point cloud has a geometry type that makes normal computation complex? Do not hesitate to share more on learngeodata.eu, we can deep dive your issue 🌞
