from particles to forms

April 10, 2009 | 8:59 pm

Hi everybody,
I’ve been using Max for 4/5 years, but I’m a perfect newbie at Jitter.
I’d like to use the particles’ system (p family) but I’d like it to produce some other forms than points…
I’m sure it wouldn’t be so difficult, but I can’t figure it.
Would someone be kind enough to post a very simple patch that demonstrates how to do this, with 2d or 3d forms?
(English is not my mother language, so an example would be so better for me.

Many thanks in advance,

Eric

i recently made this patch for a student.
demonstrates an efficient way of using particles with gl shapes. the basic idea is to send the position info from p.shiva to gl.multiple. multiple has a target gl.mesh, which gets initialized with vertex data from the matrixoutput of whatever gl shape object you wish.

Hi Eric,

Here’s a patch that I posted last year using particle to gl.multiple. Hope it helps.

best,
Zachary

Many thanks Zachary! It seems complex, but it shows me the way. Sure I’ll be able to manage with this.
More: the patch produces very nice results, and is fun to use.

Many thanks again.

Many thanks for this one too. I guess it is possible to ‘drive’ some pieces of ‘bitmaps’ too. Or perhaps I should prefer to apply texture on the 2d forms.
All this seems to cost a lot in term of graphic card utilization?

Cheers,

Eric L.
