GRASSHOPPER

ADVANCE CAD _ COURSE DOCUMENTATION

The natural world is an endless playground of ingenious solutions to problems that have evolved
over hundreds of millions of years.

 

In this course, I am working on the Grasshopper to generate complex forms that I inspired from nature and translate them into my design works.

Natural forms are a result of a collection of constraints and parameters. Using the AskNature.org, the Library and the Nature Lab, research one aspect of a biological or
inorganic morphology that occurs in nature with the goal of understanding how and why these
forms emerge. The forms can be either microscopic or macroscopic. 

- PART 1

- Present (2) options for your proposed topic of inquiry, images, and sources.

- Create a sketch of your specimen from life

- Create a diagrammatic drawing(s) explaining the morphology you are investigating. Pay particular attention to what the defining parameters are.

Topic:  Fungus

I choose the fungus as my research topic, for their rich variety of structural compositions and attractively appearances. 

To begin with, I did some pre-researches of diiferent types of fungus. Most of them have linear structures, while others look totally different. Therefore I divide my research into to parts: the linear type and the other strange types.  

・ The linear type

The first structure I researched is the linear texture under its cap, the gills.

The parameters that define the structure are quantity, diameter, thickness... Other factors such as the degree of bending, the spacing & dense and the height.

Some mushroom grows together. The way they arrange 

can also be an important factor.

・ Other types

Among these strange fungi, I am most interested in the structure of Calvatia sculpta. I can't believe it belongs to the family of mushroom. 

Steps of structure-forming,and the parameters

1. the size 

2. the number of surfaces

3. the height

4. the angle, curvature or further detail structures

02 Research

I was impressed by how the form of Calvatia scuIpta grow and transform. As It also has the linear texture on its surface, which makes its shape more interesting and challenge for me to rebuild and redesign. Therefore I chose the form of Calvatia scuIpta to go deeper research.

・ About Calvatia scuIpta

Calvatia sculpta, commonly known as the sculpted puffball, the sculptured puffball, the pyramid puffball, and the Sierran puffball, is a species of puffball fungus in the family Agaricaceae. Attaining dimensions of up to 3.1 to 5.9 in tall by 3.1 to 3.9 in wide, the pear- or egg-shaped puffball is readily recognizable because of the large pyramidal or polygonal warts covering its surface. It is edible when young, before the spores inside the fruit body disintegrate into a brownish powder. The spores are roughly spherical, and have wart-like projections on their surfaces.

・ Structure

The overall shape of Calvatia sculpta is a solid ellipsoid with pyramidal or polygonal warts covering its surface. It has a large sphere shape on the top and a relatively smaller bottom attach to the ground.

・ Stages

According to the surface texture transformation during different life period of a calvatia sculpta, I  divide it into four stages. 

Stage 1 - Bump up: In this stage, the overall body ellipsoid shape formed with tiny pump-ups on the surface.

Stage 2 - Polygons grid texture appear: The small dots on the surface continue to bulge outward, and the contact part between the dots form a line. The whole surface appears polygons grid texture.

Stage 3 - Pyramid form: Polygon faces continue to grow and become pyramids

 

Stage 4 - Crack: Continue to grow, the pyramids then crack, releasing the spores in the mushroom.

Crack and release spores

・ Parameter

For whole surface:

The pyramid textured surface is construct firstly by how many number of points , which then deicide each polygon’s size and edge.

For each pyramid:

The shape of each pyramid are deicide by the height , the curve of the axis,  twist or not, and the surface texture of the faces (which can be manipulated by the side edge or layer)
