I would like to create a 3D program with simple graphics in TI-BASIC.  I do not expect it to be very fast at all, but I just want to have the concept down for the future.  What I want to make is something that looks like a first person shooter.  I already decided that to make it work, you need a big matrix of graphics locations and 4 coordinates; X and Y for the location coordinates, W and Z for the view coordinates.  However, while I get how to do the the X and Y graphics, I cannot seem to figure out an effective algorithm for the W Z coordinates' graphics.  Does anyone have experience with this?  Thanks in advance for the help!   

No, this is my first 3D program.  I am trying to learn the concept for the future, though.  Can you help?

Moved to TI-BASIC sub-forum, because it's kinda misleading in the projects section (I had my hopes up thinking it was a new 3D project with screenshots and stuff).

I complete 3D system involves a fair bit of groundwork. That said you can make simple enough 3D projects if you dont require full 6-degrees-of-freedom movement. Luckily an FPS doesnt require this which is why you can get away without the need to store orientation in matrices/quaternions etc.

Yeah that would work, although maybe with a slightly smaller view depth, to save speed.

Now that you are in this topic, I wonder if just displaying a large bunch of 8x8 sprites using xLIB chained sprites method would be fast enough compared to drawing a bunch of lines? That would allow better graphics while still not taking too much space.

Oh I meant the BASIC line drawing commands. To be honest, they are kinda slow compared to many other stuff

Sorry, I didn't read this tread for a while...     The 90º turn angle would work well, but how would you store the data?  I guess a matrix could work, but I wonder if another method is faster, such as a list or an appVar.
