Hey, I'm currently playing with 3D particle systems. In the past I have used shiva/vishnu, java code and now gen (tanx for the samples Wes!). I'm looking for a way to draw conditional connecting lines between particles. A basic case would be to connect all particles that are within range x from each other. While I can see this done in java I'm unsure about ways to do it with regular objects and/or gen.
I think I'd need a way of iterating through the particles and build a command list for jit.gl.sketch, or to format a vertex position matrix for jit.gl.mesh.
Any ideas for efficient approaches?
