+# HE_Mesh
+
+Is 3D Geometry java library for processing by [Frederik Vanhoutte](http://www.wblut.com/) see http://www.wblut.com/he_mesh/ sketches in this folder are expected to work with version 5.0.3. The library has changed a lot over the years and not necessarily for the better (dependencies seem to be expanding exponentially, this cannot be a good thing, just look at the disaster that is ruby-on-rails)
