I don't think I understand what you want to do exactly. What kind of point you need? Inside or outside the sphere? you need to draw it as a point? Please post your patch so we can help you further.

The points must be on the surface of the sphere or in it,they simulate some speakers wich can be moved. The sphere simulates the space in wich the speakers are.

I recommend the Cosm objects. This is practically done for you in the examples and you can set it up to work with your specific speaker configurations.

Hope this helps.

thank's for help!

actually I'm not able to use Cosm object but I'll try to use it!

...what I need to do is something like the image attached...I have to control speakers position but I need to have a visual feedback of it...hope I explain better!

have you seen this patch (did a simple search to find it)?

it's from this thread http://cycling74.com/forums/topic.php?id=12184 and was contributed by Zachary Seldess

Hi, thank's, i haven't seen it before!

but...i need to give points an exact position on sphere's grid (through coordinates), not a sum of random points on it...!

how are you planning to control the placement of the red circles on the sphere surface?

I have to admit that I didn't look into the example in detail, but I figured since you are learning how to do this it stands to reason that once you know and understand how you can place them randomly on the sphere you should be able to figure out a way to do it in any location... good luck!

Hi tissi_88,

This might help get you started. You'll need to download the attached abstraction for it to work.

best,

Zachary

thank you very much!!!!

Hi everybody!

is there a way to do something like a button in the patcher that add a "point" just clicking on it?

add a point where? you can do something like that with lcd (or the jitter variants of it)
