Point cloud ok but no mesh generated

Hi, just using ptx to rebuild a mesh (already done with a statue) but here, the alignement is generated but the mesh generation take 30sec and I have no mesh at all …

here is wath it gives

Poit cloud

Mesh

Is there an option that make impossible to render in mesh my point cloud (space between points or smthg else) ?

Manythks

I have tried Mesh Calculation -> Minimal distance between two vertices and change the number from 0,000002 to 10 and no mesh was generated …

Hi acheljay2

I have tried Mesh Calculation -> Minimal distance between two vertices and change the number from 0,000002 to 10 and no mesh was generated …

To understand this right, you changed it from 0.0002 to 10.0000 ?
If yes, then you set minimal sampling distance to 10m to get say 4-6 triangles max. What was the reason to change it to this value ?

Just trying to have a mesh (I have changed step by step to watch if there is a result and not directly from one to another). It never make a mesh instead …

Just a question, is it possible to determine the density of the cloud point aligned by CR to export it to Geomagic Studio for example to make the meshing as it give me nothing on CR (have tried the export point cloud but it seems that the cloud point is really decimated) ?

Hi acheljay2

Please set the setting back to default value 0.002000 (22 sampling distance from point to point ) to get normal results.

THe PTX data are from Faro Scene or what application ?

That stay the same : no mesh generated (there is 35 cloud points totalising more or less 2 billion points in ptx format rectified from a Faro scanner). I don’t understand why it perfectly align scans but don’t make the mesh and crash every time I want to texture …

Hi acheljay2
So have you changed the minimal sampling distance back to the default value of 2mm and still no results ?
Send the data to my email address for inspection, best if you use WinRAR to pack it to upload it faster.

Hi, yes I change it. I can try to send you one part of the scan in ptx the lightest scan part is about 300Mo (or 67mo rar). I’ll watch to share it by google drive

I have send you the shared file. Don’t hesitate to ask me others if it’s needed.

Many thks for your help

Hi acheljay2
As mentioned in our email communication, you need to reset RC’s setting back to normal as there was too many settings changed to unreasonable values and probably without proper planning-feedback what they do…
The radius of scan data was set from 150 meters to 1 cm ! that is why it could not reconstruct anything + few more issues regarding settings…

Perfect, it process the 32Go point clouds in 3h26min in high details (149 clouds), now it colorises and after I’ll make a texturize. the viewer shows really superbs details !!!

Many many thks

PLEASE share your results (if you can) when you will finish.
Thanks

Texture is OK (it work at night) now saving and after suppress some meshes and mesh the high def before making the low def :sunglasses:
