covering conditions
The following presentation is a result of an exploration of various covering conditions in traditional outdoor settings. Mainly focusing on triangles and triangulation, I have learned much about the variability of triangles and its use of application through trial and error. The first half of the presentation shows the form finding approach of a specific triangular geometry and then having it repeat as a covering condition. The second half of the presentation yields the analysis of creating triangulated surfaces in Rhinoceros and Grasshopper 3D in order to create variability of the covering conditions. The result(s) were successful and unsuccessful depending in what condition I was applying the covering conditions in. A continued approach to Grasshopper will be taken beyond this project in order to further investigate its potentials in parametric design.

initial form generation
experimental forms regular twist boolean truncated
line analysis regular corner vertical
complete final form boolean fabricated surfaces
The careful study of triangles for the interim submission resulted in the variation of a specific triangular geometry that will base the canopy form. The initial use of triangles resulted in an improper way of organization in which the structure would not allow itself to flow within a surface and provide proper stabilization.

Problems with triangulation of triangles resulted in improper organization. In orger to formally have a sound system, a diagrid needed to be implemented for progression.

now that the grid is resolved I was able to create a proper diagrid for the canopy condition

after proper triangulation, I added the structural members of the resulting triangles

canopy generation
Using Rhino, and the specified geometry, I was able to test the limitations of the program in order to derive a solution for a canopy or covered scenario.
I then took my findings into grasshopper and began to formulate a definition that would allow for the geometry I had in mind while locating the center of each subsurface of the diagrid. I had complications involving the normal vector of each surface, as you can see form the bottom left hand image of the screenshot.
Basic Grasshopper definition of surfaces and subsurfaces.
Other iterations and attempts at creating a triangulated surface from points and finding the center of each subsurface, and then puncturing a hold at a specified radius.
I attempted to place the structural members on another curved form similar to a vase to see how it behaves and how those triangles would be applied to its surface. The result is a diagrid with slightly oblong circular ring that was deformed after the transformation.
Using the definitions in grasshopper, I started to apply it to curved surface to see the results. I then started to design more of a small pavilion and sheltered area rather than a canopy, which then started to switch my focus of a covering condition...
After completing the covering condition, I decided to further investigate the potential forms of my covering sheltered condition in order to realize a more realistic form that would embody the space underneath it. By using the diagrid as the structure made of steel, I can then place my triangular geometry within the space between the intersections.

By removing the bottom half portion of the shelter, I began to see what the canopy may look like from a vertical condition.
By taking those forms and applying them to varying planes I was able to see it move along various surfaces along with add materials to the geometries.
Towards the end I started to offset the structure that would hold the triangular panels to see what results I came out with. The two forms posed to be an intersting relationship.
