From 0a446d7276e74e3c8472453948204ca6463d158e Mon Sep 17 00:00:00 2001 From: Luca Rood Date: Thu, 22 Dec 2016 02:13:03 -0200 Subject: Add 3d to 2d plane mapping functions to math lib This adds two functions to project 3d coordinates onto a 3d plane, to get 2d coordinates, essentially eliminating the plane's normal axis from the coordinates.
