In this Kangaroo Grasshopper tutorial, we will use a simple method of a collision that collides a series of spheres with a solid, based on gravity! We can also add a floor to the definition and let the particles bounce on the floor!

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.

During the process, advanced computational modeling and simulation tools, such as Grasshopper and Ecotect, were utilized.

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 article Heike Matcha and Ante Ljubas employ the possibilities of parametric modeling software and customized mass production machinery to develop a design for adaptable multifunctional temporary medium size buildings made from recyclable lightweight materials and build a prototype from cardboard.

In this Lunchbox Grasshopper Tutorial, we will model a space frame structure by defining a freeform surface. Then we will project it onto the ground and use the lunchbox “space truss structure 2” to model the lines.

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 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.

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.

This paper by Wissam Wahbeh will discuss the recent use of parametric design tools as Grasshopper and DynamoBIM within BIM process. Furthermore, how the geometrical solutions could be arranged to optimize the interactivity of the final models.

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

Digital design and fabrication tools now allow us to create highly flexible building façade systems that can be customized for different con- texts as well as optimized for particular performance objectives. This thesis by Peter C. Graham develops a prototype for a flexible façade system using parametric modeling tools.

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 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.

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.

In this article the authors: John E. Harding and Paul Shepherd, propose a new approach called Meta-Parametric Design, combining graph-based parametric modelling with genetic programming. The advantages of this approach are demonstrated using two real case-study projects

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.

This thesis by Sara Torki Baghbadorani focuses on surface articulation of a shell structure constructed through a generative, parametric, modular design process. The shell form uses vault topology that adapts to varying site conditions such as topography and shape and that serves as contemplative space.

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

Resonant Chamber, an interior envelope system that deploys the principles of rigid origami, transforms the acoustic environment through dynamic spatial, material and electro-acoustic technologies. The aim of rvtr is to develop a soundsphere able to adjust its properties in response to changing sonic conditions.

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.
