# Rising Chair

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.

# Waffle Bookshelf

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.

# Perlin Noise Sphere

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.

# 3D Wall Pattern #1

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.

# Lorenz Attractor

In this grasshopper definition you can create the Lorenz attractor by using the differential equations and using the Anemone plugin to simulate the growing curve.

# Mesh+ Example #1

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

# Swarm Fashion

In this grasshopper definition we have used the Quelea plugin for agent base modeling. By changing the agents behaviour you can have different conceptual models.

# Key Pattern

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.

# Box-Sphere Pattern

In this definition we will find the solid difference between a box and a series of spheres on the corners and the face centers. then we will morph the module into a Nurbs surface.

# Geodesic Nodes

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

# Rhodonea Equation

In this definition you can learn how to use the Point Polar in Grasshopper to Model the Rhodonea equations (sin((n/d)*x)). By changing the parameters you can produce different curves.

# Attractor Loft

In this Grasshopper definition you can extrude and scale a series of squares based on a parametric point attractor. You can also control the height and scale by changing the graphs.

# Apollonian Fractal

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.

# Hilbert Curve Fractal

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.

# Arched Pattern

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.

# Erwin Hauer Pattern

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

# Non-Linear Isotrim

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

# Spiral Spikes

In this definition by using a parametric helix and modeling a series of triangles on the path you can make spiral spikes. You can also change the graphs to get different results.

# Sierpinski Pyramid

In this example you can model a 3d sierpinski fractal by using the recrusive behaviour of the Anemone plugin and then you can use the weaverbird plugin to smooth the results.

# Pinch & Spread Box

In this definition you can learn how to pinch or spread a mesh box with random points by using the Pufferfish Plugin + Weaverbird.

# Random Rectangles

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.

# Loft Point Attractor

In this grasshopper definition by using an attractor point we will model a parametric twisting surface and then use Lunchbox or Pufferfish or Weaverbird to model a series of patterns on this base surface.

# Surrounded Patterns

In this grasshopper definition by using a surface which is created from Loft and a single variable function which is controlled by Graph Mapper, you can generate a pattern that surrounded the surface thorough the function.

# Basic Aggregation

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.

# Parametric Wave

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

# Grids Juxtaposition

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

# Mirror Cut Curve

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.

# Perlin Noise Pottery

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.

# Physarealm Simulation

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.

# Diamond Panel

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.
