Retrieve vertex indices from EdgePoint

[MerlinBieling]

Hello,

I am using mrmeshpy.computeGeodesicPath to generate a geodesic path in python.

Mrmeshpy.computeGeodesicPath returns EdgePoints. I would like to retrieve the topological information of that EdgePoint, e.g. I would like to know the vertex indices of the corresponding vertices and the t-value indicating where the EdgePoint lies on the Edge.

Is it possible to directly call this in python?

Thank you!

Hello!

You can use same function available in c++:

MeshLib/source/MRMesh/MREdgePoint.h

Lines 20 to 21 in ec2cdf8

	/// returns valid vertex id if the point is in vertex, otherwise returns invalid id
	[[nodiscard]] MRMESH_API VertId inVertex( const MeshTopology & topology ) const;

from meshlib import mrmeshpy as mm

def printEpStatus(tp : mm.MeshTopology, ep : mm.EdgePoint):
    v = ep.inVertex(tp)
    if v.valid():
        print("Edge Point is in vertex: ", v,sep="")
    else:
        print("Edge Point is on Edge: ", ep.e,"  From: ",tp.org(ep.e),"->",tp.dest(ep.e)," at [0:1]:",ep.a)
