Feb 6^th, 2006, 3:40am new version of my particle system stuff at: http://www.cs.princeton.edu/~traer/physics new stuff: attraction/repulsion kill particles with automatic deletion of associated forces fast inverse sqrt new examples better docs comments and suggestions appreciated.

Would it be possible to feed/ initalize your particle
system with vectors taken from a svg file or similar,
and then use these in a similar way to the tendril
sketch, where different tendrils would represent
different paths or some such. I'm not clear about this
at the moment, as the idea is rooted in discourse
around drawing, more than it is Physics.

I've emailed you with a smiliar question, but thought I'd offer it to the general community too!

I made a small variation of tendrils, which does something similar, but instead of SVG it uses glyphs as the feed.

Click on the applet to get focus and type characters with the keyboard:
chartendril

I currently don't have time but if someone could help making or recycling a SVG importer into Geomerative it could be possible to do what you propose, mark.

cheers

Reply #4 - Feb 23^rd, 2006, 7:07pm oooh that's nice ricard! i have another version somewhere that adds another set of springs b/w every second particle which helps maintain the original shap a little more, it'd be neat to see what that looked like w/ the letters...

hey traer!!
I'm having a look at your library and it's really fantastic.

I would very much like that other T3ndril class, if you find it please post it, and I'll try to hack up a new calligraphy to post it in Caligraft.
If you don't have it handy, let me know and I'll include myself the springs to every second particle.
Although I think that I'll have to work something a little bit more complicated, since characters with more than one contour will decompose, even if the contours keep their original shapes more or less.

I've done a new version of chartendril called stringdrils where I make complete words and they are only deformed when the mouse is pressed.

Hi Ricard,

I've got the SVG importer working, and I've added strokeweights to it.

Also I've modded the AIExport to work with it too.

I implemented a follower array too and a proximity test for the heads of paths, so that a magnetize type of effect means you can pickup and shake off tendrils.

It won't applet at the mo' but I can send code if you want (bit rough at the moment, but functional).

Java Swing also uses a class called Spring, so you can't import both at the same time. Is there perhaps a way around this?

you have to either not import javax.swing.* and just import the necessary classes specifically so that it doesn't pick up the Spring class, or you have to specify which one you want in the code by using the full package name instead of just the class name.. i.e.

javax.swing.Spring spring = new javax.swing.Spring()

or whatever...

Thanks traer for an excellent library!

One question so far: What is the license on your library - the last version you didn't include the source code. Is this the same LGPL as the rest of the core Can I redistribute this library

traer YaBB Newbies Offline Posts: 16	Re: traer.physics version 2! Reply #11 - Jul 5^th, 2006, 5:55am Ooops haven't looked back here in a while. Yeah sure redistribute, just maybe put a link to the page too so people who get it from you can get updates in the future if you don't keep up. Glad you enjoy it!
