3d heading?

Hello friends

I was trying to get a 3d heading of a moving object in 3d, like the help patch of particles, using its heading output, with polar coordinates and rotation. How can i get a 3d heading of a simple moving object ? ?

tahnkss

you can patch your own heading with the framedifference node …

sorry, got no windows reachable at the moment so i can’t produce a helppatch/example

how should I map the frame difference value to a rotation value ?

I get this working, but don’t know how to go on

helos,

iirc the girlpower\RollercoasterLookAt.v4p demonstrates the non-trivial realisation of a 3d heading.

Here is the 3d heading. Its taking framedifference to former position as a vector. Normalize this vector. Mix it with some saveNhold stuff and voila your direction ;)
Oh, and taking this into a polar node as you see inside ray (3d) subpatch.
Edit: Ive made it a little more clear in the second zip. Sorry for the mess.
