# 2- Multiple Attractor Points

In this Grasshopper tutorial, we will understand what happens when we use two or more points as an attractor and how it affects our grid of points.

**20 Minutes**

**80 MB**

In this Grasshopper example file, you'll discover how to create a circle packing design originating from a collection of random points. Additionally, you'll learn to shape a 2D metaball curve surrounding them.

In this Grasshopper tutorial, you can learn how to model a parametric barrel vault from scratch by defining a rectangle

In this Paracourse lesson, you can model a parametric 2d truss from scratch by defining a series of points.

In this Paracourse Lesson, we will learn how to use the "Substrate" combined with the "Sort List" component to sort the random areas of the substrate pattern and give them a gradient color.

In this Paracourse Lesson, we are going to morph a 3D module into a target surface by defining the number of division in the u,v direction.

In this Paracourse Lesson, we are going to convert a single curve to a network surface by Learning how to use the Orient tool.

In this Paracourse Lesson, we are going to model a parametric tensile structure using the Kangaroo plugin.

In this Rhino Grasshopper tutorial, we can use the Parakeet's "Complex Transform" component to deform a simple square grid and convert it into a parametric Window.

In this Paracourse Lesson you will learn how to model a parametric wavy facade by using the graph mapper component and also shifting the pattern for each level.

In this Paracourse Lesson you will learn how to model a simple tensegrity structure by using the Kangaroo2 Plugin

In this grasshopper tutorial, you will learn how to model a zigzag parametric facade in Grasshopper.

In this Beginner Rhino Grasshopper Tutorial we are going to model a polygonal concrete Planter from scratch and then use the Pufferfish plugin to give it a thickness.

In this Paracourse lesson we will use the spatial deform component to design a parametric freeform surface pavilion.

In this Paracourse Lesson, we will model a series of rotating strips to make a Parametric Lamp and finally extract the intersections to use the curves for fabrication.

In this Paracourse Lesson, we are going to model a parametric smooth mesh using the Weaverbird Plugin. Then we are going to use some advanced techniques to convert the mesh into a building with frames/windows and slabs.

In this Rhino Grasshopper Tutorial, you can model a series of twisting boxes by defining rectangular sections and then use the graph mapper to extract the non-linear distribution of the sections. In the end, you can extract the fabrication details needed and finally nest them on the ground.

In this Paracourse lesson we are going to model a parametric helix in grasshopper from scratch.

In this Paracourse Lesson, you will learn how to convert a sphere into a series of reciprocal strips. First, we are going to use the Kangaroo plugin to model the baselines, and then multiple techniques have been used to extract the final strips.

In this Paracourse Lesson, we are going to model a parametric Nurbs stair from scratch. First, we are going to take a look at the algorithm and how we can model the stairs as easy as possible.Then we are going to model the base lines and finally the stairs.

In this advanced lesson, we are going to convert the relaxed mesh into a NURBS surface and learn how to penalize it using Weaverbird, Kangaroo, and Lunchbox.

In this Paracourse Lesson, we are going to model a Parametric Roof from scratch. First, we are going to model a simple rectangular plane for the base of the roof and then we are going to use a parametric curve to control the overall shape of the model.

In this Paracourse Lesson (25 Minutes), You can learn how to model a parametric vase by using a Perlin Noise Graph mapper. First, we are going to explain how to model the base surface of the vase by using Graph Mappers, and then we will use the Flow command to move a patterned curve to the Vase.

In this Paracourse lesson, we are going to model a parametric chair which is defined by a backbone curve and a series of wooden parts sitting on it. First, we are going to model the wooden part and then find the difference between the backbone and the sections.

In this Paracourse Lesson we are going to model a parametric weave pattern on a ring. First I will teach you some techniques to have a smooth nice-looking form and then we are going to talk about some technical ways to have a seamless result.

Good afternoon! On time 00:49, how did you delete all the nodes and connections and still managed to keep the “Group of points” intact? When I delete, the relationship is lost and the “group of points” is simply vacant. Thank you!

Hi,

I think you accidentally deleted the real points in Rhino!

You can lost the relation only if you delete the component or clear the value inside the component

Good luck!

## Cowportal

Its ok I figured it out. I had to right click on the “group of points” node and click “internalize data” in order to keep the rectangular array and the 20-by-20 count. Thank you.

Hi,

Yes! that’s great.

Good Luck!

MultipleAttractorsTutorial.jpgHello

In this tutorial I had a hard time figuring out how to get a grid of points with just one point component, it would be awesome if you explain that at the beginning.

I am attaching a jpeg image because I can’t get the surface right. When I put the 25 U Count in the Number slider I get nothing and only at two I get numerous surfaces. Please explain, thanks

Teresa-multipleattractors.zipHi Teresa,

you have add one unit to the U Count because when you’re extracting point from the surface, the U Count in the Divide Surface means number of slices not number of rows or columns so you have to add one unit to generate surface from points

I’ve also attached a file which can explain more

Many thanks.
