p5particles - new particle system library
May 25th, 2010, 7:19pm  
Hello all,

  I have created a new particle systems library which I have dubbed p5particles.

http://code.google.com/p/p5particles

I made it mostly out of curiosity and for fun, but I also felt a need for it as I found that the Traer library was too general and not "javaish" enough. I know that was his goal, but I thought something should be made with only Processing in mind. This is why mine internally uses the PVector class and relies on overriding an extensible Particle class to define your particles. I am not planning on doing much with it unless I have a partner or 2 to help improve it and get it past this hacky stage. The examples suck. I have some nice ones on the backburner w/ some walkthrough documentation but don't feel like putting them out atm. Check it out and tell me what you think!

Hi,

the p5particles.jar is missing in the download zip.

Jesus I can't believe I missed that. A little too hasty I guess. Thanks for the heads up. I replaced the file in the downloads section.

Awesome! Wish I had this last month.. would have saved me a ton of work. Smiley  Very nice - I'll be using it!  

Issues...
Attraction_3d_GPGPU example gives an error:
Cannot find a class or type named "GLTextureFilterParameters"
I'm using the latest GLGraphics v0.9.3.3

MagneticForce_test example gives me this error:
2010-05-26 11:00:32.120 java[814:180f] *** Assertion failure in -[CocoaAppWindow _changeJustMain], /SourceCache/AppKit/AppKit-1038.29/AppKit.subproj/NSWindow.m:9470

Thx!

I can't exactly recall which version of GLGraphics I used with the GPGPU example and I am not in front of my home machine at the moment. I think it was an older one like 0.8 or something. I also think I stole the shader from memo so maybe you can browse his site. Search for something along the lines of GPGPU DOF shader. It isn't the most exciting example honestly but I can reply back with more info later.

As for the Assertion failure, I have no idea what that is. It looks too deep to be my problem (or at least anything I can trace). It just started popping up. Didn't seem to cause any problems for me though.

Glad to see at least one person wants to use it! I will add some more examples and maybe update a few of the current ones either tonight or tomorrow.
