kitsch Posted February 18, 2020 Share Posted February 18, 2020 Hi, So i'm trying to reproduce this effect, just for fun: So he says in the comments it's a bunch of curves resampled every frame. I can do that and it works fine. But i'm lost on two things: the actual shape of the curves (how to make them more bubbly), and it looks like they have some kind of collisions, since they do not intersect much and mines do it a lot (he also says, there's no vellum). For the shape i've tried using the "curveu" attribute to give it the bubbly shape, but it's not quite the same. This is as far as i got, wich is a cool result but not exactly what i'm aiming for. Obviously there's room to play with the pyro sim so the lines get advected in different ways, but there's something else that i'm missing, so any pointers are greatly appreciated. advectedcurve_test.hipnc Quote Link to comment Share on other sites More sharing options...
Mohanad Posted February 19, 2020 Share Posted February 19, 2020 Hi, cool setup! Seems like your particles don't avoid each other so I added a "pop interact" nod in your popnet and since pop interact needs particle scale to work right I moved your "shape_curves1" wrangle upstream before the popnet and just added @pscale = @width. So far I see no obvious intersections. Hope this helps. Cheers! advectedcurve_test.hipnc Quote Link to comment Share on other sites More sharing options...
kitsch Posted February 19, 2020 Author Share Posted February 19, 2020 So adding a mountain node and subdividing it got me a similar enough shape. What i'm struggling now is with the collision. How do you think it's the best way to go about it? I tried using a multisolver with a RBD/vellum solver to no avail... Quote Link to comment Share on other sites More sharing options...
ThomasPara Posted February 20, 2020 Share Posted February 20, 2020 Its differential growth, so its not that complex realy. Theres a thread on this forum about it. Basicly its pointrelax set to 3d space, noise in pscale and a resample inside a solver. I think Entagma also has a tutorial about it. 3 Quote Link to comment Share on other sites More sharing options...
kitsch Posted February 21, 2020 Author Share Posted February 21, 2020 Thanks! Yes i have actually seen the post and the entagma tutorial, but i thought it was not exactly the same... Probably i have to mess a lot more with the noise. Thanks a lot! Quote Link to comment Share on other sites More sharing options...
