Pointcloud Normals

Hi,

I’m trying to convert an Open3d pointcloud to a Compas pointcloud. From the Pointcloud API, I understood that it only accepts points and name properties.

Is there a way to include normals, colors or any custom attribute (ex. labels) as well?

Thanks,
Soroush

Short answer no:

github.com/compas-dev/compas

src/compas/geometry/pointcloud.py

main

from __future__ import absolute_import
from __future__ import division
from __future__ import print_function

from random import uniform

from compas.geometry import Geometry
from compas.geometry import KDTree
from compas.geometry import Point
from compas.geometry import bounding_box
from compas.geometry import centroid_points
from compas.geometry import closest_point_in_cloud
from compas.geometry import transform_points
from compas.tolerance import TOL


class Pointcloud(Geometry):
    """Class for working with pointclouds.

    Parameters

This file has been truncated. show original

It would be great if this data structure would have
a) points
b) normals
c) colors

and all in numpy .

Maybe someone could do a pull-request for this?
