Creating a Coordinate System from Three Planes in CloudCompare

[amosfuegel]

Hello, I have three planes defined in the software and would like to use them to establish a new coordinate system. Specifically, I need to:

- Determine the origin from the intersection of the three planes.

- Create new coordinate axes based on the normals of the planes.

- Apply this coordinate system to existing point data or 3D models.

Is there a way in CloudCompare to do this correctly? Thanks.

Not directly...

Well, the normals of the 3 planes are simply the 3 first columns of your 4x4 transformation matrix that would transform any point in your local coordinate system into the global one. But for the origin, I don't think there's a clean way to extract it in CC.
