Week 10 Data Manipulation 👩🏻‍💻

Notes:

• Simplify Tree: simplify a tree by removing the overlap shared amongst all branches
• Tree Branch: Retrieve a specific branch from a data tree
• Param Viewer: a viewer for data structures — help you to understand data tree
• Line SDL: create a line segment defined by start point, tangent and length
• Merge: Merge a bunch of data streams
• Entwine: flatten and combine a collection of data streams
  • Q: What is the difference between merge & entwine? | reference link
    • Merge: when you “don’t really care about the individual lists” within the master list (or they’ve already been setup proper into their own branches). You just want to combine the lists together so you can perform an operation on only that list without having to repeat that operation for the individual lists, so it’s for clarity and speed. 
    • Entwine: keep the individual lists separate, and in their own branch
      
• Graft Tree: graft a data tree by adding an extra branch for every item
• Flip matrix: flip a matrix like data tree by swapping rows and columns

• Relative item: retrieve a relative item combo from a data tree
  • Wrap paths/ Wrap Items: wrap paths/ items when the shift is out of value
    • this can be used in the construction of the roof part in my project 2. Instead of using list, I can use this
  • Offset
• 
  • Reference Link —  The Sets-Tree-Relative Item enables you to extract 2 lists from a single list. The output of the component is dictated by the Relative Offset input. The offset has two components . The branch offset and the item offset. 
• Tree Statistics + Text Tag 3D: display the path
• Populate Geometry: to produce random points on the surface — when you connect a population to a plane, it is a XY Plane
• Surface Closet Point: project these points on the base surface
• (CP surface tool: to convert the XYZ data to UV data)

Homework Exercise

 

• My major take-away from this exercise is how to construct new surfaces on the poly surface. I also become more familiar with the Populate Geometry. Not so sure if I will use them in my final project, but it’s nice to explore more functions in the grasshopper. 

Final Project Proposal

Data: 2023 Gender Social Norms Index (GSNI) | link

Gender bias is a pervasive problem worldwide. The Gender Social Norms Index (GSNI) quantifies biases against women, capturing people’s attitudes on women’s roles along four key dimensions: political, educational, economic and physical integrity. The index, covering 85 percent of the global population, reveals that close to 9 out of 10 men and women hold fundamental biases against women. 

Data: Progress on the Sustainable Development Goals: The gender snapshot 2023｜enlace

• • At the current rate of progress, the next generation of women will still spend on average 2.3 MORE HOURS per day on unpaid care and domestic work than men.
  • For each DOLLAR men earned in labour income globally, women earned only 51 CENTS.
  • Each year around the world, 245 million and older are victims of physical and/or sexual violence perpetrated by an intimate partner.

Sketch & Concept Proposal

Sketch 1:Chinese Hair Pin

Hairpins have a longstanding association with cultural traditions and customs in China. In ancient times, the hairpin symbolized the rite of passage for marriage. 

• For me, although I don’t know how to use a Traditional Chinese Hairpin, I always think it is a very attractive accessory with immense cultural characteristics. Despite its original meaning, I am not using this object to criticize the marriage tradition in ancient China. I think it represent the feminine beauty. ✨

Sketch 2:Pasta Spoon

Why Pasta Spoon? 

• My inspiration comes from this video I watched from last semester’s class: Martha Rosler – Semiotics of the Kitchen 1975. When I talked about gender stereotypes with my friend, she told me she once saw online that some people would prepare those cleaning robots for their mums as birthday present while prepare tea pots for their dads. 

“Women belong to household work.” …? 

• This heartbreaking reality reminded me of the gender gap. Yes, in nowadays’ society, despite all the work done, there still exit many gender stereotypes, either conscious or unconscious. So I though about the video I watched last semester. I want to relate my data to some household object to better present the gender gap. 

Sketch 3: lamp 

A lamp with the pattern of Traditional Chinese Embroidery pattern – butterfly

Why Butterfly Pattern？

• I sourced my inspiration from patterns in the traditional Chinese embroidery among the ethnic minorities in China. The embroideries are mainly made by women. I’ve seen in documentaries that women of the ethnic minority groups gather together to finish a piece together. I am really impressed by this kind of human connection. These pieces are always embedded with love and best wishes. I also think they represent the tenderness and wisdom of women. (I read about it somewhere that most of the patterns were designed by women. I am really amazed by all these intrinsic designs!!)
• Embroidery is a signature of Chinese culture, and different minority groups have their own way of embroidery and own design of patterns. However, due to poor protection, these techniques are severely endangered.

I want to present the concept of gender inequality, especially biases against women. They say women can not undertake leadership position. They say women belong to household work. They say the major responsibility of women is to take care of her family. But I say, WE CAN DO ANYTHING. I want to celebrate feminine beauty while revealing the harsh gender gap.
