Birthday bracelet

This idea came from the process when I thought about the parameters. They control the final shape and different variable quantities can have different results. It seems like gene and DNA. It is a magic process for us and make us different. Therefore, I tried to use information that has the closest relationship with us. Birthday came to my mind. It’s number so that it is a perfect medium to combine people and bracelet.

I define the day, month and year in grasshopper, which are responsible for the shape and pattern of the bracelet. You can also change the wrist size depending on yourself. The most important of my design is remap, which can help me to control the parameters in an appropriate range so that we can get variable results in perfect shapes. Everyone can get their special bracelet typing their birthday in grasshopper.

What’s more, I tried to print 5 families at the end. It’s wonderful to see my own work in realistic world. However, the process is painful. I need to test the material and thickness in many times to get the perfect shape and make sure there’s no problems in printing process. Fortunately, I get a great five families and I feel this is totally worth it.

This is the first practice of parametric. My 2D interior is about the relationships. The first relationship is about hexagon and surface. The second one is about hole and curvature and the third one is thickness and curvature, so I got four variable quantities, which are surface changing, size & numbers of hexagon, size of holes and thickness of every pieces.

For the curved surface, I divide the control points in to four groups which control different parts of surface, so you can control the surface through changing these four elements. However, how to put hexagon on the surface is a very difficult step. In grasshopper, I use discontinuity and deconstruct vector to achieve that, so if you want to change the number and size of the hexagon on the surface, you can just change the grid.

For the size of hole and thickness I use planar to look for the centers of every hexagons and to find the curvature of centers, and use it to become the variable quantity of holes and thickness. Then I use remap to control the size of hole and use multiplication to control the thickness.

I use these 4 variable quantities to control the final works, but I still have a question about the thickness and vector. The extrude comes from the front and back. I know it may because of the curvatures, which are plus or minus. I was wondering if there is a way to make them all plus?

I try to create holes in the hexagon, and each size is based on the curvature of the surface. I cannot create a surface on the curved surface based on the hexagon grid. I tried to extrude the curve and then cap it, but it is very wired that it didn’t create surfaces. It is more like a 3D-cube. My laptop becomes lag because of that.

Here are mythree attempts.

1.UV & Surface

2. Hexagon & Porject

Neither of them are similer with the project I found.

I was wonderting if it is related to isocurve as .

3. Isocurve & Hexagon

Surface – Isocurve – Points – Hexagon?

It is different with the system I choose because it is a little bit difficult for me. I can feel that the change is following the isocurve of surface and the curvature of the surface but I couldn’t make it, so in this week I did a practice of the distance and radius. I will keep working on it.
