It’s nice when you’re able to apply the stuff you experiment with during freetime in real live projects. Just that was the case with the Coke X-Mas banners I made for argonautenG2. I combined my spline and particle engines to be rendered through a shared interface which produced these light-trails:

Sehr schick, ich finds nur etwas komisch dass der Strahl immer wieder zurück “hüpf” cool wäre dass er so magnetisch kommt :) trotzdem cool

Fantastic light trails, nice work you have done. The same light effect i plane to make in 3d game studio. Did you use any formula for that and can you explain details?

Thanks. There isn’t one special formula I used, more a mixture of several. I’m afraid that I can’t publish the source because this was a client project.
The basic way I set this up was having a chain of particles. Each particle has a position and directed speed and tries to follow its predecessor with a slight easing so that the movement is delayed.
If the mouse moves, the first particle in the chain will start heading in that direction and the others will just follow it as usual.
If the mouse doesn’t move, there’s another separate particle that just bounces off the edges and through the stage like a ball. This is the particle that makes the whole trail move independently.
Hope this helps a little.

Hello.
more links for that topic?
And Bye.

What exactly do you mean? I didn’t really have any resources or references for this project.

thanks for your reply. i’ ll try.
