# Loxodrome

In this grasshopper definition by Laurent DELRIEU you can model a symetric loxodrome on a sphere. It simply can be done in any revolution object. Laurent used equations from a wikipedia page.

# Undulant Portrait

In this grasshopper definition by Junichiro Horikawa you can model an undulant portrait using Image Sampler.

# Cycloid

This grasshopper example by Tuğrul Yazar is a Cycloid-like family of curves, generated by its classical description: a rolling circle. There’s no need to roll the circle but divide its path, utilizing data lists to simply rotate and evaluate it.

# Image to Curve

In this grasshopper definition, you can easily convert an image to a series of curves by using the Rooster plugin.

# Optimized Vase

In this grasshopper definition, you can connect your geometrical parametrs to the “gene” input of Biomorpher Plugin. After that, you can select between different designs and choose the preferred generated parent.

# Closest Vector loops

This grasshopper definition by Mike Pryor uses closest vector fields to model swarms inside of a closed boundary.

# Dodecahedron Structure

In this grasshopper definition by using a force diagram from the “3D graphic static” plugin you can model a parametric Dodecahedron structure.

# Random Subdivision

In this grasshopper definition inspired by Arturo Tedeschi, you can create random patterns by splitting a planar surface recursively with a series of rotating lines.

# Noise Wave

In this grasshopper definition, you can map different parametric noises on a surface by using the “4d noise” plugin.

# Structural Wave

In this Grasshopper definition, you can model a wave-like structure with graph mappers. Then you can use the Millipede plugin to analyze the form. This will give you an overview of which surfaces will give you a better parametric roof structure.

# Rotating Strips

In this grasshopper definition, you can model a series of parametric rotating strips that can cover a circle when they lay on the ground.

# Mesh Color

The Mesh Color definition by  Curvature applies a vertex color based on the average or upper value of the angles between adjacent faces.

# Triangle Holes

In this grasshopper definition by Junichiro Horikawa you can model a triangular 3D pattern.

# Sun Path Circles

In this grasshopper definition, we will use the Ladybug Plugin to import the sun path based on an epw file and the n rotate a series of circles towards the sun.

# Rotating Parts

In this algorithm you can simulate a series of rotating parts which fit together after closing. Number of segments, rotation degree and some form parameters can be changed.

# 3d Static Bridge

In this grasshopper definition by designing a force diagram instead of designing a form diagram of a bridge you can generate an optimized structure by using the 3D graphic static plugin.

# Skewed Lines

In this grasshopper definition by using a rectangle’s diameter and extracting two points on it you can generate a series of skewed lines.

# Lunchbox Truss

In this grasshopper definition by modeling two series of parametric curves and then using the Lunchbox plugin you can model a parametric truss.

# Spiral Staircase

Luis Gil who is currently a candidate for a Master in Design Studies (MDesS) degree at Harvard University’s Graduate School of Design, developed a useful tool to dynamically create and edit staircases via Grasshopper.

# Wavy Joint

In this grasshopper definition by Junichiro Horikawa you can model a series of wavy like curves with different distribution along the X axis.

# Creased Surface

In this grasshopper definition you can model a parametric creased surface by changing the scale of the base curve and also using different graphs in Graph mapper.

# Rotating Mechanism

In this grasshopper definition you can model a simple parametric rotating mechanism. you can actually change the handle’s length , width and also control the rotation speed.

# Emitted Berries

In this grasshopper definition by using Stella3d for particles simulation ,you can move a series of geometries around a defined NURBS curves while they get bigger as they move forward.

# Scaling Circle Fractal

In this definition you can model a parametric fractal based on circles.In each step the circles scale down and cover a portion of the circle’s circumference.

# 3D Printing Joints

In this definition you can model a parametric joint connection for a network of lines. The connection can be 3d printed and by defining sleeves for the pipes you can insert them in the nodes.

# Step Wall

In this definition you can model a Step wall in Grasshopper. For the base unit you can control the height, count, width and depth of the stairs.

# 3D Wall Pattern

In this definition you can model a parametric 3D wall pattern based on scaling edges of a rectangle grid and also moving the center of these edges.

# Rotating Tower

In this Grasshopper definition you can use the Anemone Plugin to rotate a tower around itself. First we will define the rotation and scaling factor and then we will extrude the base square to model the tower.

# Triangular Subdivision

In this Grasshopper Definition by using the Anemone plugin you can model a recursive pattern that connects each corner of the face to the center. You can also Mesh+ & Weaverbird to prepare a mesh or a Nurbs surface for the division process.

# Islamic Pattern

In this definition you can model a parametric Islamic Pattern which is based on connecting the center of Triangular grid to a point located on edges and then connect that point to their neighboring corner.
