+Export meshes to mr.doob's three.js 3D Engine.
+Currently supports UVs. If the model doesn't display correctly
+you might need to reverse some normals/do some cleanup.
+
+More details on the engine here:

+
+Have fun!

+Usage:<br>
+	Select a mesh to be exported and go to "File->Export->three.js" .
