from a closed LineSet to a 2d mesh

[zonderr]

Is there a way to go from a closed LineSet to a 2d mesh?
update : the 2D mesh being the surface inside the closed LineSet.

There is unfortunately no direct function for triangulating polygons. LineSet has some functions for extrusion but not sure if that can help in your case.

From the documentation for LineSet.extrude_rotation

import open3d as o3d

line = o3d.t.geometry.LineSet([[0.7,0,0],[1,0,0]], [[0,1]])
spring = line.extrude_rotation(3*360, [0,1,0], resolution=3*16, translation=2)
o3d.visualization.draw([{'name': 'spring', 'geometry': spring}])
