M3 / LIGNUM PAVILION

The task was to construct a pavilion on the MPavilion Queen Victoria Garden site using Rhinoceros' Grasshopper plugin. "Lignum" means timber in Latin. This is my first full Grasshopper-modelled project; none of the modelling processes were done on Rhinoceros.

Grasshopper modelling processes are displayed on the right-hand side of the page.

Click on the images of the script for a detailed breakdown.

Software utilised:

- Grasshopper = pavilion modelling

- Unreal Engine 4 = rendering and VR (virtual-reality)

- Adobe Illustrator = graphic details

- Adobe inDesign = pin-up sheet layout

Project start: 17th April 2018

Project end: 24th May 2018

All individually done by Geraldo Lewa.

- Move

- Negative

- Unit X

- Unit Z

- Brep (surface)

Rotate planes in accordance to an attractor point, form lines from the planes, loft the lines, and move the surface upwards in the Z-direction.

SOLID

Form solid elements of the Lignum Pavilion, which consist of: waffle studs, seats, stage, bracing, and glazing.

- Discontinuity

- Plane 3Pt

- Offset

- Negative

- Fillet

- Line

- Boundary Surface

Extract parts of the twisted surface, contour the surface fragments, extract the end points, form the waffle polylines, offset the waffle polylines inward, fillet the inner waffle polylines, form boundary surfaces from the offset waffle polyline, and extrude the waffle surfaces in both sides to form solid waffle studs.

Extract a part of the twisted surface, contour the surface fragment, extract the end points, move the points inwards by half the waffle depth, move the points inward using a Graph Mapper to form the seat depth, generate a bounding curve of the larger seating platform, solidify the larger seating platform, move the inner curve upwards, offset the elevated inner curve outwards, generate a bounding curve of the smaller seating platform, and solidify the smaller seating platform.

SOLID / STAGE AND BRACING

Extract a part of the twisted surface, contour the surface fragment, extract the end points, move the points inwards by half the waffle depth, move the points inward using a Graph Mapper to form the stage depth, generate a bounding curve of the stage, solidify the stage, move the outer curve upwards, offset the elevated outer curve inwards, generate a bounding curve of the bracing, and solidify the bracing.
