1. Project Information
Pavilion / stage for “Nature Concert Hall” is designed as an art
object that unifies all
main atmosphere making components of the event – space,
light, video and music.
Under the roof of the pavilion is a place for academic symphonic chamber orchestra
of 20 people and Nature Concert Hall music band. The elevations of the pavilion
serves as a screen for video and light
projections. Architectural volumes are referring
to existing elements in the nature. The structure of the pavilion is made in a way to
reduce the amount of
points touching the protected biotope meadow.
2. Design Objectives
The design purpose is to learn about parametric model while
constructing the
pavilion by Grasshopper in Rhino environment. The main
challenges include the
building the structural frame and controlling the
rotating curtains. To make the
model efficiently and correctly requires a
better understanding of data tree structure.
3. Build the Parametric Form
3.1 Construct the structural
metal frame
Begin with a square, I get the base lines for the structures by
moving and finding
midpoints. All the work is done by grasshopper, which allow
me to change the
dimensions of the structure.
Add more details to the structures by connecting the top and bottom ends.
After get all the structural frame base lines, I construct the section for each line,
and
give them volume to make them look more realistic.
3.2 Construct the fabric shade
roof
For the roof, I pick up the structure lines as edges, and get
them to form 8 triangular
by changing the tree structure of the data. Then use
the boundaries to form the roof
surface.
3.3 Form and rotate the curtains
First, I get the all the curtain surface by extruding. Then
divide the surface by UV
numbers and get the basic points on the corners each
curtains.
To follow the original design, each curtain are formed with the
top two corners fixed
on the structures and the bottom two corners not fixed on
the structures and ready
to be rotated.
Following steps are the keys for controlling the rotating
curtains. The top part is to get
bottom line of the curtains and to rotate these line with a series of
degrees around the
certain axis, which are set from the midpoint of each bottom
lines and points to the Z
direction. And the bottom part just to get the top
lines of the curtains with the right
tree structure.
The last step for the rotating curtains is to simply loft all
the full curtains with the top
and bottom lines. The rotating degrees and the
number of curtains being rotated can
be changed by the sliders.
3.4 Construct the base platform
The base part is extruded by the same square that forms the
whole frame structure.
4. Create the Physically-Based
Part of the Model
Create a mesh plane and add spring force and Z-direction U-force
to it with the
points on boundary and diagonal as anchor points. Then attach these anchor points
to the roof
structure to get a physically-based roof shape.
5. Analyses
Curvature analysis shows the red parts as the most twist part, which might let
more sunshine into the structure. And as I move the slider to adjust the
rotating
degrees of each curtains, the
colors would present a synchronized change.
