points to particles

[Owl]

hi there

i have animated points and i would like to convert them to particles in order to do a additional simulation.

how (if?) can i do that?

Hi, you can try using your animated points as the source points to which your particles get generated. Use Source POP. The important thing is that your animated points have velocity attribute (v) to which your particles can take off from. If you need the particles to conform to the animated points instead, check out Position POP to force the particles to move as the animated points do.

HTH.

thanks, tried attribute transfer (velocity) but haven't noticed position pop

[TheUsualAlex]

actually, Source POP should pick up velocity attribute automatically when it's birthing off from those point sources, so you shouldn't need attribute transfer unless you're doing something else with it.

yes it picks up the initial velocity but i need it on every frame until certain frame

hi Owl, As TheUsualAlex suggested, "Position POP" works pretty well. If you need to use velocity to control the motion, you may need to use "trail" SOP to calculate the velocity first, and then use "Velocity POP" to reference those values

Hope it helps,
