Surface Subdivision & Geometrical Transformation in Grasshopper

by Jan Buthke & Rune Brauer, OOOJA Architects

Folded Structures investigates the transformation of surfaces into spatial sheet/plate structures, based on parametric modelling principals in Grasshopper.
The introduced method of folding is based on plane structural surfaces, which gain their special structural behaviour through their arrangement along a surface, to achive self-supporting spatial structures of architectural interest.
By combination of structural folding principles and Grasshopper as the parametric engine, it is possible to control large folded systems and locally adjust them to specific contextual or functional conditions.
Folded Structures investigates the relationship between the overall structure and the subdivided parts by introducing parametric based geometrical transformations of points, lines and surfaces.
This logic is introduced to Pier 2, on the Aarhus harbour, to reorganize and develop temporary, artificial landscapes and structures. Pier 2 represents a centrally located urban space, which through a period of several years will remain untouched, due to temporary restructuring.
Folded Structures challenges this problem through the development of architectural landscapes and structures, that form a temporary space for recreational activities for the local citizens.
The workshop will involve both digital and physical constructions produced in Rhino, Grasshopper and on a laser cutter.

Assignment

The main assignment is to develop a design proposal for a temporary reorganization of Pier 2 at the Aarhus harbour.
The design proposal should investigate the spacial qualities of structural folds by introducing temporary, artificial landscapes or buildings constructed by spatial sheet/plate structures.
The site can be reorganized as one whole continiuos landscape/surface or as a series of specific interventions.
The proposal should allow access from the neighbouring pier at the indicated areas.
A lookout point and a public area at sea level(ig. open air swimming pool) should be established at the indicated areas.
A spatial route should connect the area(see example below).
The final proposal is represented by lasercut and folded models of the entire site at a scale of 1:200.

Surface Subdivision Concepts

An Introduction to creating surfaces in Rhinoceros, and importing them to Grasshopper, and later subdividing surfaces. Presentation of interface and tools, as well as different parameters for subdivision, such as: linear/even subdivision, uneven Bezier Graph-based subdivision and potentially growing subdivisions.

Geometrical Transformation Concepts

Introduces the elements of a surface (face, line/edge and vertices/points), and different possibilities of manipulation of surfaces, through vectorbased transformations. As the elements are constructed the transition to multi-surface-panelling is presented.

Attraction Concepts

In order to make Context-aware transformations, the idea and function of an attractor is introduced. Both a point and a curve is used as attractors, and makes it possible to parametrise transformations as rotation, scaling and extrusion. Furthermore the possibilities of if/else-statements are tested through the Dispatch component.

Export To Laser

In order to export to the lasercutter, you will need to export the model, to the Un-Fold program Pepa Kura, and afterwards changing the numeric font in order to optimize the lasercutters workflow.

Sketch Model

The sketch model is our example of a combination of the different elements that are introduced. Produced in 40×40 cm, this model contains all the different elements, such as Even Subdivision combined with Subdivision though Attractor Points and if/else-dispatch components, and geometrical transformations based on Attractor Points.

Then the model is “Baked” and exported, lasercut and folded into shape.
