Hi,

I'm a new user of Povray. It's an amazing program!!.I would like to know if
it is posible to create a physicals moldels with PovRay, like for example a
simple pendulum.

Thanks

It's not possible with the official version, but there's an unofficial 
patch called SimPOV, which can be found at

http://www-public.tu-bs.de:8080/~y0013390/simpov/

It does exactly what you're looking for :)

Of course you can render a simple pendulum in official POV-Ray, either 
by precalculating the movement and rendering it or by doing a simple 
simulation in POV-SDL (in fact for a pendulum this would be way more 
efficient than using the Mechsim patch because you can do it in 1D while 
Mechsim can only simulate it in 3D).

Yeah. I know that. Of course you can render all kind of stuff in 
POV-Ray, and model the correct behaviour either by SDL, by hand or by 
3rd-party apps. But that's not the point IMHO. Andres searches a 
possibility to "create physical models". I think the pendulum was only 
an example. And you're the last person one has to tell that SDL is not 
the best way to create those (more complex) models ;)

But you're right, I should have pointed out that one could also do the 
calculations in pure SDL...

Thank you very much for the quick answer!!!

Excuse me, I don't understand what is SDL and IMHO. But I have been seen
that sim-Pov in Christoph's Page is very very interesting and I want to
study in more detail.

Thanks again!!!

Yes, Cristoph's website is very useful, not least because of his
Sim-PoV.

SDL = scene description language, the language .pov files are written
in.

IMHO = in my humble opinion. It just means that the writer is offering
his opinion, not a generally known fact.

I didn't finish it yet, but you may take a look at a system I'm developing
for robotics simulations (actually rigid-body dynamics). There are some
videos at:

http://www.inf.ufrgs.br/~dmbasso/phi/

There you find the source code for the newton cradle (3 pendulums) too.

Cheers,

Daniel

Ohhh!! It's great your link. It's just what it was looking for. But I'm
lost. What version of PovRay did you used? You used Megapov or SimPov? I
have tried to compile your source file of newton simulation and I have
several problems. I used Megapov version 1.0 and Povray 3.6 but they seem
there are incompalible on a Windows XP machine.

Thanks.

Thank you :)

I use povray 3.5 for rendering, but the physics are done through my
framework (that uses the Open Dynamics Engine library).

Those source files are in Lua syntax, and are read by Phi (my robotics
framework) to get the scene description. It's not an extension to the
PovRay SDL, so indeed it couldn't be successfully read by povray or
megapov.

Once Phi is ready for the masses you'll be noticed ;)

Cheers,

Daniel
