Approaching orbit

[grimvisions]

Hi all,

I was wondering how some of you would approach a shape orbiting another.

I've explored using wave generators so far and have made some...progress.

Open re-entering the scene the orbit resumes a diagonal back and forth trajectory. If i reset the wave generator moving either axis this resumes a sort of orbit motion, however I have no actual control over it's path.
Any advice would be greatly appreciated. :)

Cheers
Ed

@grimvisions

Could you share the patch you have, so we do understand a bit better what you want and what you already have?

Best Michel

Sure Michel, thanks for your response.

I'm working with isi 1 still. Upgrade is a Christmas treat, so have included a print screen.

The trigger's on the stage background are a clear way of watching the path...thought it would help.

Cheers

you need to adjust the phase on one of the wave generators. set it to 25 will create circle path. 75 will reverse the direction

Thanks @LPmode

I will post a JS solution shortly.

I forgot how to format code here in the forum..

so I added a page to my blog. http://www.dusxproductions.com/blog/javascript-based-orbits-in-isadora/

hope that helps  !! (**sorry**.. only just now noticed you have Isadora 1, this JS solution of for Isadora v2 )

Hey DusX,

Thanks for such a brilliant mini tutorial.

I'll be upgrading to Isi 2 in December. (Can't wait)

I'm really keen to try some java script so will definitely give this a try.

The math in the Javascript is pretty straightforward.. it would be pretty easy to build it using standard Isadora actors (math etc..)

It would probably run much faster since the native actors run as C++
