Links to 0.962 and 0.973 added to the OP, thanks for pointing that out Cooleo8bit.

Question what is the latest version that would work on Intel HD 3000 Graphics-which use Open GL 3.1 on Windows?

SE 0.971 works reasonably well. At the moment, I'm mainly working with this.

So Jack, if she gets that version she can see planets and land on their surfaces and stuff?

It should. But do not expect miracles. SE generally does not work well with Intel graphics and especially with this card.
And it is very very slow.

Thanks Jack, what's a good resolution and LOD setting to use for it?  4 GB RAM of which 1.7 GB is used for Video Memory.  Can a resolution of 1024x700 be used with LOD of 0? Is that what you use?

This is the first CGI rendering of a complex landscape (with 3D clouds, islands and water). It was done in 1981. I saw it today and it reminded me of SE. In some sense this is the beginning of it all.

This is very impressive for the time period it came from.

I'm curious, how much time it took to render that video, and on what kind of hardware. And, maybe more interesting, what software was used, and how long it took to create it and setup the scene.

The info I was able to gather says that this was rendered by a raytracing algorithm in FORTRAN using a Cray-1 supercomputer, a 5.5 tons monster with 8MB of RAM and a 64-bits system. The graphic memory was of 2MB, enought to store 2 frames of the movie at any time, these were then stored in magnetic tapes. Apparently they made the decission to render only the lower part of the frame after the first still image of the islands since the important changes were ocurring only there (water waves). Because of the simplicity of the periodic motion of the water waves only a few frames were needed for this part and replayed in a loop. The ambient and atmospheric colors were added after that by another computer. The Moon and the Sun are also post-processed as far as I understand the original paper.
For a typical frame of the video:
  • 34 seconds of computation time on the Cray-1
  • 5 minutes to record it on a Dicomed D-48 color film recorder
  • 45 seconds to backspace the tape twice between color passes
So the entire movie probably took something like a day or two to render.


I didn't read it carefully so you might want to check the original paper:

I remember a time when the planet Bloop orbited Rigil Kentaurus (Alpha Centauri) B, before being replaced with a planet candidate that, to my knowledge, was never confirmed. I miss Bloop.

Messier, you can just rename it.  In my Alpha Centauri addon, I think its part of the Avatar addon but need to check, it has those planets still but renamed to proper exoplanet names.

lol yes, I must restore it, maybe in the Avatar addon :)

Please do, that'd be amazing! And quite nostalgic too!
