hey Siggmuss,

very nice patch, yup, it's the problem of the separator, I've edit the patch a bit and play around. If you change the translateXYZ, there's no change of the whole structure.

cheers,

I think there's a "seperator" object that does that, if I understand your question correctly. I can't get PD in front of me at the moment so I can't double check.

hi Peter and list many thanks for your help and examples, im making some awesome stuff with this!!!

well i have a new question... maybe you can help me: the idea of the patch is a camera that travels to weird places, i have a problem with this because if i change the parameters of the translateXYZ , rotateXYZ, it affects the whole structure, and i was wondering if there is any way of affect just the incomming ones. for example i want that when i change those parameters , begin affecting to geos that are far away (not all the structure at the same time) , so all the structucture will change progresively . i have no idea of doing this. any idea would be nice thanks

here is the patch!

ive tried putting the "separator" object. I think maybe you dont understood my question I know how to rotate or translate the image without affecting its structure using separator objects. What im trying to do is to affect the structure, but not the whole at the same time)all the balls). what i want to do is for example : when i change translate or rotate, begin affecting the balls that are far away no the ones that are near of the screen. So all the structure will change in a "progressive" way.

many thanks siggmus

That may sound simple logically, but with the current structure of the program, it doesn't really work so easily. It's important you realise that all of the positions are calculated pretty much fresh every frame. In fact, I can't stress enough how useful it is to thoroughly understand which calculations are computed in which order, and with the results of which other ones etc. The structure (roughly what I implemented) in the patch you're working on is a fairly specific case, I think, and maybe not a good one to work from.

Assuming you carry on using my algorithm, you could perhaps try something nifty with tables... as the function iterates and the index increases, you read different values for [rotate] / [traslate] for each iteration. Off the top of my head, you should increment a write pointer once per frame, and use the index for the read pointer. I think. That would take a bit of programming, but could achieve the desired result, and by the time you manage it you'd have a far greater understanding.

As for moving the camera, you need to use view messages to the gemwin, (which involves computing what the messages should be).

p.s. you do realize that the 90 in [pd fmod 90] has no effect on the program - it was misleading of me to post a patch where it looked like that was an argument for substition. If you look inside, too, there is no $1, so nowhere for that number to be plugged (not that this would happen in a subpatch, anyway). Frank just posted on this, but I don't know if you read that / clicked. This is why you had overlapping elements, rather than one long line.
