Title: Is there any kind of "physics simulator" for the Amiga?
Post by: AmigaMance on March 15, 2007, 07:16:00 PM: Hi.
Let me explain what i'm looking for...
I'm looking for a program that let's you set a scene of objects/particles and allows you to set various attributes of each object like mass, velocity, elasticity speed and global attributes like acceleration of gravity, wind, friction etc, etc and then produce some sort of 2D or 3D animation out of it.
I have only found some simple "gravity simulators" like gravity well on aminet.

If I remembered the name maybe a google search would find it? Then you could port it to AmigaBASIC...

Let me retrieve the backup logs from my longterm memory to see if I can come up with something.

Post by: AmigaMance on March 16, 2007, 08:38:02 PM: That would be nice, hotchalupa. Thanks. Although my knowledge on BASIC is limited, i could give it a try.
Now that you mention it, i remember that i stumbled upon an AMOS basic program while browsing my Amiga magazine CDs... It was called "Super-Magnet" or something and it could produce some very impressive 2D animations of flowing water, explosions etc. Iirc, the executable was not included, only some animation demos. :-( It was on a AF or CU CD. I have a lot of them so it will take me a while to find it.
Does anyone remember of this program?

Actually, now that I remember it, I think it simulated light/lasers acting on prisms, etc.

I think they want to avoid terrorists from learning physics. :crazy:

It does all the physics simulations you refer to, and even has its own programming language (FORTH based).

I imagine other 3D rendering software such as Cinema4D and Imagine would be able to do nearly the same, but Real3D was the most advanced 3D software for the Amiga.

Post by: asian1 on March 17, 2007, 03:27:09 PM: Perhaps you can use Java Applet with Linux PowerPC on AmigaOne/Pegasos, Ode Physics SDK, or Free Physics from Sourceforge.

Is it possible to port the open source programs to AmigaOS?

IIRC there was a cover disk from Amiga Computing magazine in the UK that had some physics type stuff on, I know the stuff you mean. It was dead clunky as I remember.

I don't remember any rendering programs for Amiga that did any sort of physics, built in. Not even Lightwave. Are you saying that the programming language for Real3D allows people to program their own physics effects or are there some already built in?

I've programmed particle simulators. The hardest part is collision detection. I remember reading about techniques developed even back in the 70's where the key to three-dimensional collision detection was not to have any concave objects. Anyhoo, Real3D has that kind of functionality?

Post by: SamuraiCrow on March 18, 2007, 01:33:16 AM: I think what Real3d had was called a "kinematic motion module" that would allow simulation of 3d physics but not in realtime.
