Reimplementing PointCloud.segment_plane on Python

[evbernardes]

I am trying to re-implement PointCloud.segment_plane in pure Python following the C++ implementation here. The reason for that, is that as a second step I am going to create other types of segmentation methods that follow a similar procedure. I imagine this is the only implementation available since the Python hooks are generated automatically, am I right?

However, I haven't been able to find a way to call many of its internal methods/classes on Python. For example, the Python equivalents of RandomSampler, or EvaluateRANSACBasedOnDistance.

Is there a way for me to call these functions, or are the hooks for internal functions like those not generated?

@evbernardes The hooks are not generated automatically. There is /Open3d/cpp/pybind/ directory which generates python bindings for code in /Open3d/cpp/open3d/.

For e.g. - See https://github.com/isl-org/Open3D/blob/master/cpp/pybind/geometry/pointcloud.cpp#L199 binds C++ method PointCloud::SegmentPlane to new python method segment_plane.

I did quick search, but it looks like there is no binding for RandomSampler or EvaluateRANSACBasedOnDistance.

P.S. - Feel free to add a PR for this.
