phew! Just submitted mine now, with 30mins GMT time to go

great screenies/demos guys, they surely look a whole deal better than mine :oops:

Good luck everyone! :D

I don't think it uploaded, I can't see it in the FTP directory... Can you send me a link by email or something?

Yep I've got it.
Also for anyone else who might have been punished by my crappy upload form, see the other announcement thread

Wow impressive guys original and polished stuff. Looks like the compettion will be very close.

If you want modern rendering techniques learn how to make them or go to the engine next door =p

Those boids could be very good for racing game ai, the target would be the next part of the track while the boids code will give enough variety in the motions to prevent all the cars from hitting each other or finishing first every time.

I submitted... 8)
Actually I'm quite happy about the motivation I had, no matter the outcome... Hope you guys like it.
Can I post a link to it here, or should I wait ?
EDIT:
Anyway... just in case that bitplane dump didn't work...

and now...

EDIT2:
can't stop playing with it :) should be sleeping... drawing pirouettes around the sun... Bouncing from orbit to orbit around the solar system... This text that I found yesterday describes the gravity simulation pretty accurate actually...
from
The math needed to calculate accurately the motion of objects within a gravity field (in one, two or even three dimensions) is actually quite simple. We'll be using an iterative method to solve what's called the "two body" problem. We simplify the problem even further to assume the smaller particle has no effect on the black hole.

For each moment in time, we update each particle's position based on its current velocity vector. Next, we calculate the square of the distance between our particle and the black hole. We use this as the (possibly scaled) denominator of a gravity constant to find the force of gravity being felt by the particle, thus implementing the inverse-square-law of gravity (and most other forces). The particle's current velocity vector is then updated to include the force of gravity (the vectors are added together). Lastly, we trim a small amount of velocity away from each particle, in order to simulate a slow decay of the orbits.

This simple algorithm produces true orbital dynamics which subscribe to Kepler and Newton's laws, providing the particles don't approach the singularity too closely. As seen in the image above, the orbits are ellipses, as first realized by Johannes Kepler in the early 1600s after studying the orbits of the planets. Newton later came up with his law of universal gravitation, and showed that orbits can also be parabolic or hyperbolic. Both of the latter orbit forms are "open" (the particle escapes), and can appear in our simulation.
and from my readme:
Our Solarsystem is a vast place.
This model has proportional planets and orbits, but their distance to the sun is scaled by 1/100000. In reality those planets would be 100000x farther away...from here you wouldn't be able to see them, not even a pixel. Also the sun's radius is divided by 50. The planets masses, thus gravitational attractions are altered. Except for that, it's as real as it gets. The planets position is calculated by painfully hard maths (I really dont get it), and supposedly accurate for many centuries ahead, The gravitation simulation is somewhat simplified. The maths is painfully easy, even for me, but it obeys newtons laws.The distance you can read down-right is real, so is the speed.

W-A-S-D controls your craft...
W moves your ship straight up, S moves down,
A moves your ship left, D moves right,
think of them as thrusters in 2 axis, up-down, left-right.
It is important to understand that we're moving in zero G. That is nearly zero gravity, because right now...we are chaotically orbiting earth. The blue circle you can sometimes see is your flightmarker, if you look at it and press the left mouse button you will see we're accelerating !!! If you press the right-button your reverse thruster ignites, so it's a truely 3-dimensional movement, still unlike any aircraft you might have ever flown. It can get a little confusing, but you'll get used to it. Search for your flightmarker to understand your movement.

The easiest way to get into an orbit with a planet or the sun is keep looking at it and adjusting your ellipse and distance. Or just sit back and watch Keplerian dynamics unfold...
enjoy...
EDIT3:
Well... hmm I've been working alone on one system... runs smooth on my macbook and on my toshiba, also GL... Its just a core duo with nvidia go7600...
@tecan...
turn off all tangent meshs and normal maps and kick earth atmosphere... but you can't possibly

Code: Select all

	 scene::IBillboardSceneNode* earthBill = smgr->addBillboardSceneNode(0,core::dimension2df(80,80));
//	earthBill->setMaterialFlag(video::E_MATERIAL_FLAG::EMF_LIGHTING, false);
//	earthBill->setMaterialType(video::E_MATERIAL_TYPE::EMT_TRANSPARENT_ADD_COLOR);
How's that going to look :roll:

I love the sound of irrSolarSystem cause it's from BladeRunner :D my fav -SciFi-Movie!
Controlling the Craft is really strange I think...but it's really nice altogether

I vote for zillion42's project, its top quality, what better way to display motion than with a simulation of satelite orbit. I hope this project is fully developed into a space game, it would be awesome.

omaremad's project won't download...
