This is 256 line C++ tinyraytracer by Mr. Dmitry V. Sokolov (ssloy) ported to several higher level game engines.
Some older ones (but still quite popular) and some more recent ones.
All projects are made to display execution time in milliseconds, so that performance could be measured.
Operations include: trigonometry, vector math and data structure handling.
It is unoptimized - no lookup tables, no fixed-point, inlining, etc.,
which presents more life-like model and evens out the playing field.
Shaders are not used.
Drawing routines are not timed.

- OpenGMK, RGDirect and MKXP are runtime replacements for already assembled binaries.
- Execution times below 1 sec. reported with higher precision.
- Digital Mars C = Symantec C = Zortech C
I added for reference timings from MS DOS16/32 version using various compilers and extenders,
running on Am5x86 133, which is basically a beefed up 486. They used to rate them as Pentium 75 or 90,
but that was marketing - they were noticeably weaker than those. I'll probably come back to this
and update it with optimized version - lookup tables/fixed point math, which would be typical
for this hardware. Probably won't do assembler optimizations though.
These projects could also be useful as a 'Hello World!' programs, when moving from engine to engine
and you want to familiarize yourself by jumping right in, instead of going through tutorials.
Enjoy!
