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