Hi all,
I've been absent a l-o-n-g time.
As usual I'm after easy answers :rolleyes:
2 projects.
No.1 project needs a fairly accurate rail-modeled path of motion of an object on Earth - say, in England - as the Earth moves through our Solar System (including the motion of the Sun on whatever path it is moving in) over a period of 100 years.
No.2 project needs to know how to render a 3D object as an anaglyph (red-green filter glasses viewable).
Is anything else needed other than trueSpace 7.5.1?
Here's hoping both are really not that difficult :jumpy:
Love, Rob |

Maybe some Indian Sitar music.:p
=======================
Sounds like an interesting project, look forward to the replies and suggestions offered. |

Hmm, not sure about project 1. But if you wanna make a stereoscopic video you simply need to render 2 passes of the same thing, but each render should be from a different camera, By which I mean, you need to position 2 cameras right next to each other, at a distance similar to that of each of the human eyes. Then you need to composit both renders together, using adobe premier you can select a stereoscopic filter, ill try show u an example |

This (http://www.arachnoid.com/raytracing/anaglyphic_3d.html) tutorial isn't for truespace, but it covers the theoretical aspects nicely. |

The orbit tracking could be done with procedural animation if you have 7.51. (input formulas)
Here's a nice page with graphics of early observers about orbits.

My honours project was a piece of software that plotted objects around bodies in the solar system. There's a fairly simple way to work it out that isn't exactly how it happens but a good estimate and the formula is fairly basic.
Unfortunately, that was like 13 years ago and I can't remember a thing...
Things I do remember is that the planetary orbits are not circular and not on the same plane, Earth is roughly circular. The orbits are not elliptical but more an egg-shaped orbit, with an apogee (furthest point) and perigee (closest). Also, there's an elevation factor, again earth I think is level but not sure. You then have the rotation and orbit periods. Earth is actually roughly 23 hours and 57 minutes rotation and 365.23 days for 1 orbit. Then when you want to make it more accurate, and this actually affects satellites more than planets, you have perturbations which, if I remember correctly, is the affect that atmospheres, solar wind and solar flares have on bodies in space.
I have pretty comprehensive notes on this but back in Scotland... |

If you only need the sun, you can use this sunposition calculator:
http://forums1.caligari.com/truespace/showthread.php?t=2282
If you need the other planets or from an other place in solar system, it
will be very difficult. And if you need 100years, I think TS is not exact enough.
You would need hundreds of sin cos etc terms.
Maybe you can use an astronomy program with export function of the
ephemerides. Then you can import these textfile datas with a script.
and transform the ephemerides to a position in the TS world.
Still not easy. |

:banana: WoW! :banana:
What a great response from all of you. Thanks a million times.
I'll be busy for a few weeks digesting all of the tips. :)
Particularly, I think the whole anaglyph rendering thing could be quite an interesting avenue to pursue.
I'll post anything that looks decent, but it will take a few months what with day-job and lots of other backlogs.
So, does anyone have any '3D Stereoscopic' render .wmv's to show off?
Cheers,
Rob |

Reminds me of my first 3d software love, "Imagine" - had an anaglyph render option right there on the render requester. I know I did some experiments in those days - god knows where they are now. |
