In this grasshopper definition, you can create noise on any surface by using the Tundra plugin. For example we have used the Mobius surface component by Lunchbox plugin.

In this grasshopper definition, by using the Fox & Pufferfish plugin you can model different expressions of minimal surfaces.

In this grasshopper definition, you can create a voxelized shell shape by subtracting two volumes and finally model a Triply Periodic Minimal Surface.

In this grasshopper definition you can create a 3d sine iso surface by using the Axolotl Plugin.

In this grasshopper definition by using standard minimal surface equations, you can create different minimal surfaces and also use Align vertices to avoid generating an invalid mesh.

In this grasshopper definition by using the PerlinNoise component of the Noise 4d plugin you can produce a changing value for a iso surface which is generated with Millipede.You can also subdivide the mesh surface to have a smoother result.

In this grasshopper definition you can create a surface which is based on the Chladni equation. You can also make the mesh faces colorful by a gradient and Subdivide the surface by Weaverbird plugin to have a smoother mesh.

In this grasshopper definition you can create a grid of boxes and change their oreintations by using the CurlNoise Component.

In this grasshopper definition you can use the “facet dome” component to cover a sphere with voronoi cells and then move the centroid in the normal direction to finish the model.Finally you can use the weaverbird plugin to smooth the geometry.

In this grasshopper definition by exploding a mesh sphere and by using the Pufferfish plugin you can extrude the faces towards their normals controlled by a sine wave.

In this definition you can model a fractal based on a square which builds two smaller squares on one of its edges.

In this definition you can make a fractal rotating polygon by using the Anemone plugin. First we are going to explode the curve to its segments and then evaluate a point on the edges. This recursive algorithm will produce the final rotating polygons.

In this grasshopper definition you can model the shadow of a hypercube(tesseract). In geometry, a hypercube is an n-dimensional analogue of a square and a cube.

In this grasshopper definition you can model a parametric 3d curve by giving a base curve.

In this grasshopper definition by using the 3d Maurer rose formula and combining it with Dendro plugin you can create a parametric form. In geometry, the concept of a Maurer rose was introduced by Peter M. Maurer.

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 grasshopper definition by creating relative tangent circles which revolve around each other and create different spirograph patterns.

In this definition you can use the expression a*(sin^b)*(cos^c) to produce a parametric mathematical curve and then loft three of these curves to make the final surface.

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.

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.

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.

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

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.
