 Ray Tracing for the TI-84 CE

A ray tracing engine written in C++/ASM for the TI-84 CE. This engine
is capable of

  * Scenes of arbitrary sphere and plane primatives
  * Difuse and reflective shading
  * Texture mapping
  * Dithering
  * Gamma correct rendering and HDR tone mapping
  * Global illumination through radiosity

and can render the scene shown below (at standard resolution) in
about 12 minutes.

Check out this video for more information and to see the renderer in
action.

 Try It Yourself

Note: Due to reliance on some eZ80 hardware instructions, this
program can only be run on CE or later model calculators from the
Ti84 family.

 1. Download the binary here.
 2. Download the CE C Standard Libraries.
 3. Load both onto your calculator using the TI Connect(tm) CE software.
 4. Run the ASM program either with Asm(DEMO) or your favorite
    graphical shell.
 5. The renderer will take a few minutes to compute radiosity.
 6. When the graphics have completed rendering (usually takes about
    12 minutes) press any key to exit to the OS.

Warning: This program takes a while to complete, and once started
cannot be interrupted until it is finished. Every once in a while, it
can also freeze up. If for any reason you need to quit the program,
you will need to reset your calculator, which will clear any
unarchived data in RAM. Make sure you don't have anything unarchived
that you wouldn't be willing to lose before running this program.

 Building Locally

This program appears to have some compatibility issues with the
latest version of the toolchain, however version 9.1 still appears to
be functional.

---------------------------------------------------------------------

Looking for the older TiBASIC version, instead?

This was written using the CE Programming C SDK Toolchain.
