AlphaVFX has posted a video showcasing its Object Velocity Plugin for Max. It calculates velocity vectors that can be used to drive FumeFX simulations, lights and many other things. To watch the video you can head over to the AlphaVFX Vimeo channel. There you can also find a link to download the plugin.

I’m not sure I understand this. Why do we need a plugin and a pre-calculation? Couldn’t it just be replaced by a float_script controller which goes
multiplier * ((at time t (obj.pos)) – (at time (t-1) (obj.pos)))
?
I mean yeah you could do that. This is just the way I like to do it and it exposes the Position Velocity and Angular Velocity. Also since its animated you don’t have to override anything with an controller. You can have a light depend on velocity then lets say at frame 220 you want to change it manually you can.
This is just a tool I use and thought someone else might find a use for it 😀
You’re right, I see the advantage in it. The FumeFX example is particularly cool!
sorry, that should go
multiplier * (distance (at time t (obj.pos)) (at time (t-1) (obj.pos)))
