Surface Force should work with other particles as vertices - MatthiasM - 04-02-2019
right now i can already use vertex as sample method for my surface force, if this would also work with particles from another tyFlow as vertices, that would be really helpful for things like upresing particle simulations and make them look more crisp and sharp
amazing work so far!

Hey MatthiasM,
"Point force" is probably what you want if you want particles to act as little force fields.
However, for upresing simulations, there is already a dedicated operator: particle force. You input a separate flow and it will advect your current flow with the linear/angular velocities of the input flow based on a set radius. It was specifically designed to do upresing.

yes thats exactly what i am doing but for more detailed simulations the upresing from interpolated proximity velocitys alone tends to become blurry by the nature of its functionality so i want to slightly pull the particles towards the reference particles at the same time. Also "point force" only works in a self related way and not for negative/attracting values like the surface operator right? I imagine attracting and repelling my particles towards/away from particles of another flow

Which build are you using? I added the ability the set negative force values on point forces earlier today

thx this helps a lot!
