Detailed Description

template<typename MeshType>
class walberla::mesh::TriangleDistance< MeshType >

Adds information required to compute signed distances from a point to a triangle.

The class adds vertex, edge and face normals to mesh. The normals are calculated according to [Baerentzen2005] to allow for a numerically stable sign computation. To compute the point<->triangle distance, we use the rotation method described in [Jones1995]. Some data is precomputed to allow for faster computations and is stored at each face in an object of class DistanceProperties. The numbering of vertices, edges and voronoi regions in the rotated triangles are shown here:

A rotated triangle in the planar coordinate system. The vertex numbering is shown in red, the edge numbering in blue and the numbering of the voronoi regions in green.

The class offers multiple methods to get the distance/signed squared distance from a point to a single triangle or the whole mesh. Please note that the distance computation for whole meshes is rather inefficient. Instead you should an object of this class into a mesh::DistanceOctree reduce the computational complexity from \(\mathcal O(n)\) to \(\mathcal O(\log n)\), where \(\mathcal O(n)\) where \(n\) is the number triangles.

Additionally to the signed squared distance you can also retrieve the closest point on the triangle or mesh to your point of inquiry. You may also retrieve the corresponding normal and the closest voronoi region.

Template Parameters

MeshType The type of the mesh, e.g., mesh::TriangleMesh.
