FVector2d ChangeBasis ( const FVector2d& Vec,
int32 EdgeIndex
) const

 Express the vector in terms of a basis that is aligned with the EdgeIndex edge of the triangle. Operations/MeshGeodesicSurfaceTracer.h  

double DistanceToEdge ( int EdgeIndex,
const FVector2d& Point
) const

 EdgeIndex = 0, 1, 2. Operations/MeshGeodesicSurfaceTracer.h  

FVector3d GetBarycentricCoords ( const FVector2d& PoinInTri2
) const

 Barycentric coords for this point in the tri2d. Operations/MeshGeodesicSurfaceTracer.h  

FVector3d GetBarycentricCoordsInSrcTri ( const FVector2d& PoinInTri2
) const

 Convert a point on this tri, to Barycentric coords in the un-rotated source triangle. Operations/MeshGeodesicSurfaceTracer.h  

double ProjectOnEdge ( int EdgeIndex,
const FVector2d& Point
) const

 Closest Point on the edge, given in terms of 0,1 parameter measured along the edge (EdgeIndex = 0, 1, 2) Operations/MeshGeodesicSurfaceTracer.h  

Vector3Type ReorderVertexDataForSrcTri3d ( const Vector3Type& DataOrderedForTri2d
) const

 Convert vertex data ordered for this FTangentTri2 into vertex data ordered for the source 3d triangle. Operations/MeshGeodesicSurfaceTracer.h  

void Reset()

 Reset just invalidates Tri3ID Operations/MeshGeodesicSurfaceTracer.h
