In this video tutorial, I will explain how to use image sampler to produce a complex form based on an image in grasshopper. The image sampler tool will use u,v point mapping to extract the brightness and we can use it to manipulate geometry.
8- Based on height

8- Based on height

In this grasshopper tutorial, I will model a facade louver system based on scaling. First I will divide the facade into louvers and then I will extract the lines and scale them based on the height of the surface. then we will remodel the louvers with another technique and use point attractor and image attractor to affect the facade.
9- Based on colour

9- Based on colour

In this tutorial, I will explain how you can use Gradient to color a set of panels based on their height.

10 – Attarctor triangles

In this Paracourse lessons you can use a series of point attractors to change the scale of a square grid and then connect the corners to the middle of the scaled border.
11- Paneling Attractors

11- Paneling Attractors

In this Paracourse Lesson, we are going to use different attractors in Paneling tools to model a parametric grid that deforms with Point/Curve/Random and surface curvature. Finally, we are going to smooth the result.
12- Parametric Hexagons

12- Parametric Hexagons

In this Paracourse Lesson, we are going to model a series of hexagons which scale based on point attractors. We are also going to study how to fix the cells on the closed Nurbs surface seam.
13- Rotating Panels

13- Rotating Panels

In this Paracourse lesson, we will model a series of rotating panels which extrude until they reach their neighboring surface. We will use three different techniques :

14- Paneling Tools (List)

In this Paracourse lesson, we will use the Paneling Tools plugin to cover a Nurbs surface with a series of modules. We will use point attractors to distribute the modules and in the end, we will count each module and export them in different layers.
Single Point Attractor

1- Single Point Attractor

In this Video tutorial, you will learn how to use a single point attractor in your design. By understanding the concepts you can get ready for more complicated attractors and how to control them in the next tutorials.
