Atari ST Raytracing (Part 1)

In the early 1990's ST Format gave away the POV (Persistence of Vision) raytracer on one of its cover disks.  ST Format 49 - August 1993.

Being too dumb at the time to understand the raytracing script, all I did was spend days rendering the accompanying sample pictures.

The below images weren't rendered on the ST (I unscrupulously 'borrowed' them from the Internet), but they're the samples provided with POV back on that old ST Format cover disk. 

All were rendered 160x100 or 320x200 back in the day - would take hours upon hours!  POV would spit out targa image files that I'd then import into Spectrum 512 - which allowed 512 colours to be displayed on screen at any one time.  Which in the early 90's, was pretty swanky.  Probably won't mean much to anyone unless you also had that cover disk!

Car - I remember this one took the longest by far, 24hrs +

Chess - This one also took ages 18hrs+ but it was worth the wait!

Pool - this one didn't take as long, maybe under 6 hrs

Pacman - this was also a quick one, could get it rendered in a morning!

Earth - probably the quickest one to render, could do it in a few hours

  2. By the way. Check out "Atari Forum" if you like this.

    I just joined a month ago, and I am having fun looking at some of the old things that made me happy as a kid. Especially music and 3D art like this. So many fun things on these retro computers, make modern ones look boring!! lol
