how to resolve STL Mesh Export: Inconsistent Triangles, Duplicate Vertices, C++?

[JihoKang24]

I used the code below to add specific points before loading this file

`

for (int i = 0; i < iNumPoints; i++)
{
        vxdouble3 d3PosHitWS = pvtrCurvePoints->at(i);
        vxfloat3 f3PosHitOS;
        vxfloat3 f3PosHitWS = d3PosHitWS;
        VXHMTransformPoint(&f3PosHitOS, &f3PosHitWS, pmatWS2OS);
        vtrPoints[i] = Vector3f(f3PosHitOS.x, f3PosHitOS.y, f3PosHitOS.z);
        if (vtrPoints[i] == Vector3f{})
        {
            continue;
        }
        
        auto res = mesh.findClosestPoint(vtrPoints[i]);
        if (res.has_value() && useImprintVertices[vtrPoints[i]] == false)
        {
            useImprintVertices[vtrPoints[i]] = true;
            auto eSplit = mesh.getClosestEdge((*res).proj);
            auto eId = mesh.splitEdge(eSplit, vtrPoints[i]);
            usetImprintEdges[eId] = true;
        }
}

`

then I load stl file I got this warning message how to resolve this errors use meshlib c++

64 triangles were skipped as inconsistent with normals.
43 vertices were duplicated to make them manifold.

thank you for your helps

Hello!

This messages in MeshInspector basically mean that loaded mesh was not manifold. So we duplicated some vertices and skipped some triangles in order to keep loaded mesh manifold (using this function).

MeshLib/source/MRMesh/MRMesh.h

Lines 36 to 42 in 852a95d

	/// construct mesh from vertex coordinates and a set of triangles with given ids;
	/// unlike simple fromTriangles() it tries to resolve non-manifold vertices by creating duplicate vertices
	[[nodiscard]] MRMESH_API static Mesh fromTrianglesDuplicatingNonManifoldVertices(
	VertCoords vertexCoordinates,
	Triangulation & t,
	std::vector<MeshBuilder::VertDuplication> * dups = nullptr,
	const MeshBuilder::BuildSettings & settings = {} );
