Description
This method 'unrolls' a point cloud from a cylindrical (or conical) shape onto a plane:


Procedure
Select a cloud then start this tool.
Cylinder
To unroll a cylindrical shape, the parameters are:
- axis of revolution (X, Y or Z)
- radius
- and optionally a point on the axis (otherwise CloudCompare will try to guess it by computing the cloud gravity center)
Cone
This method unrolls a cone in a way that preserves surfaces.

To unroll a conical shape, the parameters are:
- axis of revolution (X, Y or Z)
- half angle (this is the aperture angle at the cone apex - in degrees)
- the cone apex position
Straightened cone
This method actually unrolls a cone-shaped cloud as if it was a cylinder, by first 'straightening' the cone walls.

To unroll a conical shape, the parameters are:
- axis of revolution (X, Y or Z)
- half angle (this is the aperture angle at the cone apex - in degrees)
- the cone apex position
