Blast from the past: Turbo Pascal raytracer

PaweÅ‚’s recent post reminded me of a veeeeeery old raytracer I wrote in years 1985/89. (Yes, young ones, we had computers then!)

Header states:

1985-07-10:
  Computer: VAX-11/750
  Language: Pascal V2
  Graphics: VT100

1988-02-03:
  Computer: IBM-PC
  Language: Turbo Pascal 4.0
  Graphics: EGA 640 x 350 x 16

1989-07-03:
  Computer: IBM-PC/AT
  Language: Turbo Pascal 5.0
  Graphics: VGA 800 x 600 x 256

Quite a blast from the past – the 800 x 600 in 256 colors (out of a great palette of 262144 colors!) was more or less the greatest graphic card which you could get for PC at that time. And the first version was running on a VT100 terminal with an additional graphics board. Sadly, I don’t have that code anymore :(.
