December 10th, 2018 - Modeler gets its (temporary) raytracer
... and after 9 long and brain-melting hours of intensive programming (from scratch), a bunch of cups of tea (and countless cuddles of my better half), I have a working raytracer that actually bounces "light beam placeholders". Now to debug and fix what needs to be fixed tomorrow, and the biggest milestone will be behind me! Phew!! Now for a well-deserved nights' sleep!
