Missing dense point cloud #26

Open Vynikal opened 2 years ago

Vynikal commented 2 years ago

Hello, in 0.8.0 version, I am unable to locate the densePointCloud.abc file, as seen in the node MultiviewStereoCL and the command window. Is it a bug, or am I missing something? My objective is to export colored point cloud, but I can't find how.

Hi @Vynikal, the "densePointCloud.abc" file will only be created if you enable the "Compute Visibility" option in the MultiviewStereoCL attributes (it is turned off by default).

If you just want a file with your reconstructed color point cloud, then I'd recommend using the file named "fused.ply" which is always created and is located in the same folder (.../MeshroomCache/MultiviewStereoCL/xxx/fused.ply). Creation of the "densePointCloud.abc" file is disabled by default because it requires extra time and RAM to generate, since it contains visibility data in addition to the point cloud data.

Yes, it took several hours and whole RAM. Then it froze and BSoD'd 😄 The resulting file is 6GB big JSON. Don't know why or what to do with it.

Yes, I'd recommend that you just ignore the "densePointCloud.abc" and big JSON files.

Does the "fused.ply" point cloud file work for you?

Yes, it's ok, CloudCompare is able to import it.
