Point Cloud from cc_HObject #208
Description
title: Generate point clouds for child components of a mesh using CloudComPy
labels: question, enhancement
Description
I'm working with a .obj file that contains multiple components, structured like this:
A
- B
- C
- D
I'm using the CloudComPy API to convert this mesh to point clouds. However, I'm encountering difficulties when trying to generate point clouds for each child component (B, C, D).
python
import cloudComPy as cc
cc.initCC()
mesh = cc.loadMesh("path/to/.obj")
child = mesh.getChild(1)
The child object is a cc_HObject, which doesn't seem to contain mesh or point cloud information.
Questions
Is it possible to generate a point cloud for each child component of the mesh?
If so, can we set properties like colors and normals for each respective point cloud?
This is possible in CloudCompare, by selecting each child component and sampling a point cloud for each child component.
Additional Information
The .obj file is obtained from a Siemens NX CAD drawing.
Expected Outcome
Ability to:
Access each child component (B, C, D) of the main mesh (A).
Generate a point cloud for each child component.
Set/Get properties (colors, etc.) for each generated point cloud.
Any guidance or examples would be greatly appreciated.
Thank you!
