4:24 These simple 3D mazes are easy to write; they can even be done in BASIC. I experimented with this kind of maze, but never turned it into a full game. I wrote more complex 3D effects on both the TS1000 and TS2068, but since they were in BASIC, they took forever to render.
On the TS1000, I created a rotating oscilloscope with a 3D projection. I did this on the TS2068 as well. On the TS1000, I was able to animate it by storing 16 screenshots in memory and switching the screen pointer. It looked incredible. On the TS2068, I implemented a kind of ray casting that created a 3D chessboard with an infinite number of squares projected out to the horizon. I also created a 3D pyramid projected in a 2.5D isometric view.
Unfortunately, I sold all of these effects—along with some simple BASIC games—as a product called The Great Game and Graphics Show. It sold well, but in hindsight, it was closer to a demo than a fully realized product. It was 1984, and I was just getting my feet wet writing software for personal computers.
