algorithmic modeling for Rhino
Still new to Grasshopper and using fields & attractors. I'm trying to use several point attractors to pull other random points towards the attractors based strength by distance (simple enough, right?). I understand (kind of) how the point attractors can be used to modify the scale of circles, for example (like most basic tutorials show). However, I can't seem to get the random points to move towards the attractors properly. I'm sure it has to do with vectors and adding vectors, but I don't really understand how they work.
if you are feeling lazy you can use my add-on Nudibranchwhich has embedded an automated multiple attractor component.
Please refer to the examples especially the point attractor one.
Thanks, I'll give it a try.
wow. Marios. It is really impressive. Espeically reaction and diffusion part. Thanks a lot for the good work.
Thank you for the feedback.
There is going to be a major update on Nudibrach (hopefully soon :) ), that deals with bug fixes and also introduces a few new components.
Hi, I just found this discussion. I am pretty much in the exact same position as mark was. I looked at nudibranch, but I have no idea how it works. I am dealing with a surface that I have applied a popgeo battery. I cant really figure out how to use attractor points or curves to create a swarms of density in isolated areas.
I haven't had a chance to look at your files, and this might not work for what you are doing, but I had some luck (with varying results) by grouping points by proximity to the attractor point(s). Once grouped, I could move the point towards the attractor using a two point vector and some math.
To really get the result I wanted (again this might not work for your purposes), I ended up using a random cull by distance to the attractor point(s) and bumping the original point count way up. The result gave me a clumpiness of points that dispersed by distance.
Thanks Mark, Would you happen to have a definition I could look at? I am still pretty new to all this and dont entirely understand how everything works.
I don't have anything here with me now (I'm at work) but I'll post some definitions tonight when I get home. If you don't here back from me, send me a reminder. In the meantime, check out this link and see if it helps at all. This is what I used to learn the grouping technique.
Great thanks mark! I'll check this out.
glad it helps :)
Forgot the file. Typical.
