Skyscraper

The creation of a basic skyscrapper using Rhino 6+Grasshopper

Curves and Arches

What originally started as a normal curve was later scaled on both the x and y axis. The later colouring part was made to show the peaks the lows of the height of the curves with the shorter (cooler one as blue) and the higher (hotter one as red).

Cityscape

I was told not to use two attractor points too late…

Double Attractors

While the previous time I used double attractors but using the same function twice, it can actually be simpler

I kind of like this new colour scheme, it looks subtly comic booky.

Also, played with fields and vectors

Tried to model this

While I was able to make the general pattern, out and eventually move the geometry into a certain height. The problem arose when I started to divide the polygons into segments. There must be a way to snap the triangles into the sides of the polygon. I’m still finding out how to align the triangles, and have them align according to its length. The polygon tool allowed for regular triangles. Still I believe it can be done. There are functions that I probably have not thought of, or mathematical work arounds…

Got to try out meshes today. We spent time understanding the basics of meshes using 2D and it was quite cool to see things being generated into triangles.

After the initial creation, I was quite bothered by the fact that the mesh is flat depite it giving an illusion of depth due to the triangles. One of the things I remember from a behind the scene of the newer Star Wars animation was the creation of the deathstar using polygons… it’s not quite a mesh I think but I thought it would be nice to try out.

It was a bit blocky for two reasons… I was not aware of a mesh sphere function, so I had to find my way around it by making individual planes and divide surfaces on a sphere… but it looked not too bad I guess… with a couple thousand more points and tangential planes, it’ll be smooth in no time.

But then I was told there was mesh sphere…So..

It’s not quite done, there was not enough time to reconcile the mesh faces. But I think it is smoother already… except that it looks like a space discoball now…

Got to deal with Kangaroo today and the arches turns out to be quite cool. Especially when made into a small volcano.

Sun

Today we tried to model a sun that has petals that are attracted to a point. There were some hiccups on the way but eventually, it was done. However I felt that the script I had made was very inefficient. I don’t know why but I felt like the whole thing could be done with a lot less functions, but I had to find work arounds to things… causing the script to bloat up.

Surfaces, their segments and Egg Waffle

We were playing with the surfaces and dividing them into segment. In the end we were told to do something with each individual segments. There are complex geometry and there are tasty ones. First thing that came to ny mind was these Taiwanese Egg waffles, so I populated the surface with spheres, and we have a grasshopper egg waffle.

Exercise

Nothing much, just exercise
