 This is an example implementation of the *closest point on mesh* algorithm. Given any 3D point and any mesh, it should find the closest point on the mesh to the given point in a maximum given radius. A GUI comes with it to demonstrate the results and performance. Automated tests are available in the program. They test the low level methods of the algorithm.

 # Performance
 
-Here are some performance results of my implementation. Tests were made with an AMD Ryzen 5 3600 3.59Ghz. The implemntation only use one core.
+Tests were made with an AMD Ryzen 5 3600 @ 3.59Ghz. The implemntation only use one core.
 In the following tests, all vertices were normalized in the range [-1, 1].
 
 The obj files I have used are available in [common-3d-test-models](https://github.com/alecjacobson/common-3d-test-models).
