It has absorbed me more than any other project I have worked on, it has alternately driven me almost insane with frustration and astounded me with its ease of implementation, it is my most graphically impressive, smooth running and well optimised project; and hence I have decided that my 3D engine, the longest running, and in many ways most sucessful of my obsessive endeavours, deserves its own section on this site. In the case of Trooper II, its ownly rival in terms of scale and programming labour, I can estimate a figure with regard to the number of hours I spent putting the game together: this is impossible with the 3D engine. There have been many times when I have forgotten about the whole thing for months, only to return more ardent to improve the perspective, to make the texture mapping more realistic and the engine slicker. The engine has appeared in three different incarnations, with only its very core central to all of them: firstly in my BGI 3D version, which was blessedly simple compared to the hulking complexity of my modern work: in the faux-textured mapped version using MCGA, and in the modern; genuinely texture mapped with lighting effects and dynamic loading of 3D models; version, which has taken me countless hours to refine, and which I have only so far used for graphical demos. I have attempted to represent this work on these pages, and to make available to you all the tools I use for making my simple 3D demos, if in the unlikely case you want to employ my libraries to make your own 3D game. The history section consists of the early 3D descriptions in the early projects section, which I feel is extensive enough to satiate my users' incessant curiosity. I have split the information on the actual mechanics of the engine into two parts: the perspective and 3D engine, and the texture mapper, which you can access on the submenu to the left. The 3D library units, and the tools I use to create my 3D models and 3D world can be downloaded in the Units and Tools section; and my most recent 3D demo is available for download in the ultimate section of these pages. Copious screnshots, of both the antiquated engine and my most recent demo are also accessible from this menu. I hope all this is comprehensible; if you are interested in developing your own engine, I suggest you build it from scratch as I did (my own code is not very instructive), but make use of tips I'll include in the description of the function of the engine. Happy modelling, Jon
