# 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.

In this grasshopper definition by offsetting and scaling one of the Parakeet's Tiling components (patterns) you can create different patterns. this grasshopper definition uses Parakeet and Weaverbird plugins.

In this grasshopper definition by creating relative tangent spheres which revolve around each other you can create different spirograph patterns in 3d space you can also use Dendro plugin to convert these complex curve to volume.

In this definition we have remodeled the Rising Chair by Robert van Embricqs in Grasshopper3d. First we have made a rectangle and then by two parametric curves the bending of the parts will be defined.

In this definition you can make a simple Waffle bookshelf without using any plugins, First, the 3d boxes are modeled based on thickness and depth and then the details are modeled in several steps.

In this definition we will use Perlin noise as the base deformation of a sphere. Perlin noise is a type of gradient noise developed by Ken Perlin in 1983.

In this definition we will use some geometrical transformations to model a 3d wall panel. First we will model the rectangles and then we will turn them in to 3d.

In this definition you can learn how to optimize a bounding box of a solid by using Galapagos and by rotating it around the x,y,z axis. Finally you can use a few simple commands to visualize some of the Data in the rhino viewport.

In this definition we have used the Mesh+ Thatch weave command to produce a parametric weave pattern on an untrimmed Nurbs surface.

In this definition we have made a pattern based on a rotating and scaling square grid which the center connects to the middle of the edges and then by following a geometrical algorithm we reach the final pattern.

In this definition we will use the node points of a series of geodesic lines to find the best plane for the cylindrecal connections.

In this definition we have used the Anemone plugin to model the Apolloian fractal. In mathematics, an Apollonian gasket or Apollonian net is a fractal generated starting from a triple of circles, each tangent to the other two, and successively filling in more circles, each tangent to another three.

This grasshopper definition is generated by putting simple scaling and rotating into a loop through Anemone Plugin, however it is quite different from the method that mathematician generate the Hilbert Curve fractal. A Hilbert curve is a continuous fractal space-filling curve.

In this definition a set of gene pools are used to create the main surface and then data tree has been used to extract three sets of curves to create the pattern.

In this grasshopper definition we will model an Erwin Hauer pattern based on the "Still Facing Infinity" exhibition.

In this exercise you can learn how to divide a Nurbs surface into a non-linear division by using graphs.

In This grasshopper definition you can learn how to model a series of random rectangles on a circle. For example this can be used to model a circular mirror.

In this grasshopper definition you can learn how aggregation method works by creating a loop with the Anemone plugin. In each iteration, the faces of the meshes will generate a new face.

In this grasshopper definition you can use the point attractor technique combined with Heteroptera plugin to model a wavy like surface.

In this grasshopper definition we have modeled two series of 3d patterns based on a square grid which can be controlled parametrically.

In this grasshopper definition you can model a parametric form by cutting a series of curves with a plane and then joining them with the mirrored result.

In this grasshopper definition you can model a parametric shape by defining a series of circles with a Perlin noise function controlling the radiuses. At the end we will use the Dendro Plugin to voxelize the final shape.

In this definition we have used agent based modeling to simulate growth of the agents and reaching the food source by using the Physarealm plugin.

In this grasshopper definition a 2d pattern panel is created using the diamond panels of the Lunch box plug-in and different variants of the diamond panel is created using basic components to control thickness and shape.

In this grasshopper definition we have used the Rabbit Plugin to produce a parametric L-System by defining rules and number of agents (Turtles). The Starting position has been found on a sphere

question.jpgI have a problem, if I created a surface in Rhino which had some crown on it and an irregular shape ( I did a square then projected curves and trim it) seem Grasshopper is reading the complete surface and not the trim part, how could I add the edges of the surface?

Hi Edgar

Remember that Rhino/Grasshopper is a NURBS modeling software and if you have watched the basics we have explained that a Trimmed surface will be paneled on the untrimmed surface. Grasshopper uses u/v network to make the panels so you should try to make a pure NURBS surface if you want to fit it on the whole surface. You can also trim the overhanging edges.
