Attract Particles to the Closest Point of an Objects Surface | Houdini 19.5

In the last video we looked at the theory behind attracting particles to the surface of an object. This video builds upon that knowledge and looks at attracting particles to the closest point on an objects surface in Houdini 19.5.

You answered the exact question I had, thank you. I thought I was going to be spending a lot more time hunting around for this solution

[@InsideTheMindSpace]

Happy to help!

[@YuI-tj4nl]

Nice work!

[@mtk2productions143]

thanks man, great style of teaching :)

[@InsideTheMindSpace]

Thank you! Glad you found it useful

[@Deepin2soul]

thank you very much!!!!!!!!!!!!!!!

Hi, thanks for the follow up. A question though, do you have to get the position using the primuv function ? After all you are getting the mygoalprimuv from the xyzdist function and the pop attract is asking for a goaluv. Just curious what the difference between the mygoalprimuv and the position from the primuv function is.

[@InsideTheMindSpace]

Thats somewhat of a complex thing to answer. You can certainly try it but I don't believe that works. I would recommend watching some things on the xyzdist function and primuv since that isn't necessarily the focus of this video and a dedicated video would give a better understanding than what I could give in a comment.

[@shivdholakia]

great tutorial! if you had a particle sim with the forces and right behavior how would you convert them to rigid bodies?

[@InsideTheMindSpace]

I'm not sure that you would really be able to easily since rigid bodies interact with each other and push themselves around and particles wouldn't have that interaction. You could maybe try to find a way to make a velocity field from your sim and get somewhat similar behavior but it wouldn't be exact.

08:16 you didn't assign a value to i@mygoalprim and v@mygoalprimuv, and then you define variables "goalprim" and "goalprimuv" without using them anywhere else in the code.. am I missing something?

[@dinosaursneverexisted8985]

ok so apparently the xyzdist function will assign values to these variables/attributes for you... my bad!
