I'm proud to announce a new Cemetech project that I have been working on over the past two weeks or so, ever since I because obsessed with the insanely good Blockland and the TBM mod that goes with it. It is called Brix Builder, an is a fully 3D toy brick CAD program for all TI-83 and TI-84 series calculators. What makes this revolutionary is the first true perspective/axionometric, wireframe and hidden line hybrid rendering engine ever to be created in TI-BASIC, a very efficient engine that will soon be released separately as the ReaL3D Engine v3.0. It sores data in highly compressed lists that allows huge models to be created even wtihin the miniscule RAM of the TI-83/84 series graphing calculators. The first version of the hidden line render had several flaws that I fixed with a not-quite-finished second version; you can see screenshots from each and from elsewhere in Brix Builder below. Feel free to post in the Brix Builder forum topic.
