#grasshopper attractors

[miled72]

In this third part of the Grasshopper series on attractors for beginners, we will learn about another component called Curve Closest Point, another alternative way to have attractor points affecting your shape. I recommend you also watch the first two videos in the series to have a better understanding about the attractors' logic, even though this video, by itself alone, presents a good explanation on its own. In the video description, you can find the links for the other two videos, also a link to download the demo file used in the second part that I used as a starting point for this tutorial.

video compression crunched this one pretty bad unfortunately! i'm still pleased with it though.

this is an icosahedron being rotated in 3D, then converted to 2D polar coordinates and back to cartesian with z-offset generated with simplex noise and the polar radial distance. colors are determined by point proximity to attractors, as are the sizes of the circles. i built this sketch in grasshopper and have been spending a lot of time playing with it - small tweaks produce very different effects.

here is the same set of points (without the simplex noise) viewed from the top, with only the hue determined by an attractor (as opposed to an RGB value constructed from three attractors). hue is a value from 0 to 1, so if you map it to a bigger domain (this was around 0 to 70), it wraps around and produces a high-frequency gradient. i tried animating this one but it was very flickery and hard to look at!

Experimenting with attractor based densities in grasshopper with outputs then taken from biomorpher. Next step is applying this to our generated site boundary.

Mantid, scorpion, grasshopper from Zion last fall. Idk which, cry about it to Dr. Phil, incels. Oh and some nice geology. Mantids are cockroaches are sibling taxa, thats neat. Got some ootheca pics from a few places for later. I saw a mule deer here too. Go watch Ellis' new vid if you havent already. Nothing to do with anything, just a good video. Better posts coming when I feel better. I am a klein bottle of excuses, a Lorenz attractor of rhetorical dodges. #obscurity #comforting #zion https://youtu.be/xU1ffHa47YY (at Zion National Park) https://www.instagram.com/p/B3K26GuAUJw/?igshid=ui62yu01v2zg

Parametric design - Week 2

Part 2

On further exploring grasshopper I generated a tile that consists of hexagonal projection with higher embossing on the centre and descending depths toward the edges following youtube tutorials.

Trial A 

In Grasshopper, I scaled down the attractor curve to gradually change the array of shapes on each layer. This change in dimensional variations created a type of gradation.

In this Grasshopper tutorial for Beginners, we will learn about the Closest Point component. This component expects two collections of points, and it will go through the first collection one point at a time, measure its distance with all the points in the second collection, and place a point on the point with the shortest distance. It will also output the distance values. We will see how to use the distance values to create interesting shapes. We'll keep this tutorial very simple.

Rhino Grasshopper Create Patterns with Curve Attractors

Project 2, Stage 2 Surface Detail Problems

Of course since all of the previous stages of making my master model were problematic this stage had to be too. 

As a test piece I set up a Voronoi pattern to project onto the top surface of the orthotic.

Typically this is done by creating a flat pattern and using surface morph to project this onto the surface however this wasn’t working and I couldn’t find any solutions that would get it to work.

I found another strategy to achieve similar results using the map to surface tool.

After a lot of messing around to get it to work it did project the pattern down to the surface, however it was always over-sized. I tried various solutions and data culling strategies to try to fix this to no avail. 

I didn’t just want to project the flat pattern straight down onto the surface because I was worried at how this would deal with the near vertical side and back walls of the orthotic, but after no other solution worked I had to just go with projection. 

It gave a surprisingly good result even though it was the bottom of the pile of considered solutions.

I could then use a trick to extrude these projected shapes so they could be used for cutting ventilation and patterns into the surface of the orthotic. This would simply be done by booleaning the resulting forms. However both Grasshopper and Rhino would fail r crash when trying to boolean these shapes. I then tried exporting these shapes and using Meshmixer and Netfabb to do this (Netfabb has incredibly powerful boolean tools and will often manage operations that other software can’t) however both failed since the mesh that was being produced in Rhino’s export came out broken.

So I had to rethink what was possible to do for this project since I was now out of options and out of time. I decided to simplify the user customisation to just using curve and point attractors to make surface patterns.
