How to Implement Distance Compare option in c++

[cometKim96]

Hello Devs,

I'm trying to implement Distance Compare function in MeshInspector UI.

Is there any example code I can follow?

Thanks in advance

Hello!

You can use this function:

MeshLib/source/MRMesh/MRPointsToMeshProjector.h

Lines 53 to 60 in d64341c

	/// Computes signed distances from valid vertices of test mesh to the closest point on the reference mesh:
	/// positive value - outside reference mesh, negative - inside reference mesh;
	/// this method can return wrong sign if the closest point is located on self-intersecting part of the mesh
	[[nodiscard]] MRMESH_API VertScalars findSignedDistances(
	const Mesh& refMesh, ///< the distances to this mesh will be returned
	const Mesh& mesh, ///< the distances from valid vertices of this mesh will be returned
	const MeshProjectionParameters & params = {},
	IPointsToMeshProjector * projector = {} ); ///< if projector is not given then CPU's computations will be used

with CPU or GPU progector:
