ARCH655 Project 1: Modeling of thallus installation
DESCRIPTION OF ARCH655 PROJECT 1: the modeling of thallus installation
The production of this model mainly relies on grasshopper
and kangaroo to complete. There are three main steps in the modeling process.
1. Simulating the curve pattern.
I started it with a basic curve in Rhino and I divided the curve into a series of points. Now, the curve was a collection of many lines. Then, tether the curve to geometry boundary by using mesh.
In this stage, I started to use the Kangaroo plugin to achieve
the physics simulation. The first one is Bouncy Solver. I also need to set up
the Button, Dumping, Toggle and Strength. Then, I settled the Segment Length
for curve which will influence the result.
For avoiding the Crossing Curve, I used the Collision. It
will give the curves a force to push each other away.
Then, I also need to set the angle goal to ensure that Line Segments
are smooth and flat. Therefore, set the value to zero to ensure that there is
no angle between them.
Next, I adjusted all the parameters to make sure the pattern
looks similar to the sculpture.
2. Establishing the basic shape and surface of the
sculpture.
First, build an enclosed cylinder in grasshopper.
For creating the arching effect of the cylinder, I used the
Graph Mapper to change the shape of it.
According to the appearance of the target sculpture, I need
to maintain the shape of the bottom of the cylinder while distorting the top. Simply
put, what I need to do is changing points on the bottle except the start and end
points of them.
Finally, putting all values together then using Nurbs Curve
and Loft to generate the basic surface of sculpture.
3. Mapping the pattern onto the surface of the sculpture.
I used the Map to Surface to achieve this goal. Then, connecting
it with Loft (surface of sculpture) and the Lines (curve patten), thus, the
curve pattern on the plane is projected onto the columnar surface.
To get a better outcome, I also replaced the original curve
line with a more complex curve.
After adjusting all the parameters, the ideal shape was
formed. Next, stop the simulation and visualize the curves by using Mesh Pipe. Finally,
using Custom Preview to see the effect, of course, you can also bake them
directly.
So far, the modeling of the original version is complete.
Through adjustment of parameters, the model will also undergo interesting
changes and generate brand new sculptures.
