UE::Geometry::IsSphereMesh

Detect if input Mesh is a meshed approximation of an analytic Sphere, and if so return best guess in SphereOut.

Windows

MacOS

Linux

Syntax

namespace UE
{
    namespace Geometry
    {
        bool UE::Geometry::IsSphereMesh
        (
            const FDynamicMesh3 & Mesh,
            FSphere3d & SphereOut,
            double RelativeDeviationTol
        )
    }
}

Remarks

Detect if input Mesh is a meshed approximation of an analytic Sphere, and if so return best guess in SphereOut. Fits a sphere to input points with several rounds of incremental improvement, then measures chordal deviation of edge midpoints.

Returns

true if mesh is a Sphere and SphereOut is initialized

Parameters

Parameter	Description
RelativeDeviationTol	distances from edge midpoints to sphere surface are allowed to deviate by 2RadiusRelativeDeviationTol
