Laplace growth & Dielectric Breakdown Model with a fast simulation algorithm (Lightning creation) July 19, 2018, 5:41 p.m.

Hello Kulli,
You don't mind sharing with me the hip file? I'm currently exploring this effect using the above algorithm as well.


this is my (hopefully) last post regarding to this Project. I have successfully finished, as mentioned before, the Solver, and was also able to create a digital asset with different options:

1) Create a Grid (2D or 3D) which will work as the point cloud for the pattern to grow. The user also can plug in a given point cloud (Created on a geo surface e.g.), but those points shouldn't be placed randomly all over and should at least have an even distance to each other for being physically accurate (although I find results with at least a little randomness visually more powerful!)
2) Create Obstacles like boxes or spheres or other geometry. (The user simply needs to plug them in). Different values can be set for the rejection effect. This allows the user to optimize the simulation
3) Create a point as “aiming location”. This way, the user can add a point and set different values for the amount of attraction. Being able to do so will lead a lightning or other sim in the given direction.

This is it! A video about the creation can be found here [vimeo.com]. Another one showing a lightning bolt [vimeo.com].

There are a ton of other possibilities for the pattern. I am experimenting in a 3D growth behavior and a RBD object breaking apart according to the growth pattern (This is gonna be a nice one!).

well, I'm still not quite sure where the file is, can someone just post a file link so I can download it right away, thanks.

default skin shader displacement error March 31, 2018, 11:07 p.m.

well, it would seem that I have solved the problem by manually adding the displacement global variable to the shading network tabs
