 # TriangleMeshDistance
 Header only*, single file, simple and efficient C++11 library to compute the signed distance function to a triangle mesh.
 
-The distance computation to the triangle collection is accelerated with a sphere bounding volume hierarchy. The sign of the distance is resolved with the method presented in *"Generating Signed Distance Fields From Triangle Meshes"* by Bærentzen, Andreas & Aanæs, Henrik. (2002).

The sign of the distance is resolved with the method presented in *"Generating Signed Distance Fields From Triangle Meshes"* by Bærentzen, Andreas & Aanæs, Henrik. (2002). Assuming triangle normals point outwards from the enclosed volume, the sign of the distance will be positive outside and negative inside.

 ## What you need to know about TriangleMeshDistance
 - The input triangle mesh must be fully connected and watertight. Triangle soups and meshes with holes will return the correct distance but the sign will be undefined.
+- Triangle winding (consistent normals orientation) is not verified. The input mesh is required to have consistent normals.
 - `TriangleMeshDistance` keeps a copy of the vertex and triangle data.
 - The pseudonormals required to compute signed distances are calculated and stored at building time.
 - `TriangleMeshDistance` can be declared empty and constructed multiple times with different meshes. If the new mesh needs less memory than the curent one, memory allocations will be avoided.
