We are happy to announce the second Perth Computational Design Group event, with two excellent speakers doing some amazing things!

The event was hosted at AUDRC on Tuesday 10th Sept, 2019 with a turn out of 58 attendees.

Charlie Boman - Roland Snooks Studio

Charlie Boman is graduate architect at Roland Snooks Studios and a research assistant and sessional tutor at RMIT.

Studio Roland Snooks explores the complexity of the contemporary social and natural world through the creation of objects, installations, public art and architectural projects. This work draws on an understanding of the underlying processes of formation that give rise to these contemporary conditions. The studio redeploys these processes through algorithmic techniques in the creation of highly detailed and intricate forms.

At RMIT, Charlie is involved in a body of research that explores advanced manufacturing processes. such as innovative ways of 3D printing. Charlie is currently researching cmt welding as a means of metal printing.

Implementing GIS Workflows for Architectural Visualisation by Daniel Giuffre

Previous Post: GIS meets Architecture - why?

In Western Australia, there is a wealth of geometric data collected on everything from landscape topography, building footprints, road networks to seasonal flood mapping. This powerful repository of data is mostly made available to the public through open data initiatives like data.gov.wa.

At ifLAB we work with GIS data within Architectural modelling environments to assist in both decision making and visualisation processes. Our GIS software of choice, the open source QGIS has some 3D capability, but compared to 3D modelling software, it is not a productive environment to work on new designs. We prefer workflows that utilise each software package for the task it best suited for, so while QGIS is excellent as aligning different types of Data, when it comes to 3D modelling, Rhino is our tool of choice.

An example of how we are using GIS data in practice is generating an accurate topological mesh with a high-resolution texture generative from satellite imagery. When we download satellite imagery, we get the option to download a text file that contains information about its geographical coordinates. We use QGIS to align the image with other datasets we have downloaded from data.gov.wa (for example, topographic contours). This avoids having to convert between mapping projections manually.

Exporting everything as a shape file, we bring the information into Grasshopper with our current GIS Plugin on choice; Meerkat. Meerkat has an interface to trim down shape files to a given area. By setting the area to be larger than the downloaded satellite image, we can get all the information we need without processing data from the entire state and overloading the system.

[Figure 2: Mesh and Aerial Texture overlay

Within Grasshopper we make a mesh of the points brought in from the contours, and trim it down to the extent of the satellite image. Using the excellent mapping tools from the Human Plugin, it’s simple work to give the new mesh planar mapping, set to the location and dimensions of the original Satellite Image bounds. Within grasshopper we programmatically make a new material with the original image and bake the mesh with the new material and the correct mapping.

The output is similar to a Google Earth 3D model, only because we control the sources of data we use, we have control over the process, and can use it for modelling the way we would use any other piece of geometry in Rhino. We can also rely on the result to be as accurate as the sources of data that we use.

The end result with other sources of data overlaid becomes a useful tool to see how designs respond to their context, with a range of other applications.

Responsive Lighting with Arduino, Firefly and Grasshopper by Daniel Giuffre

With the advent of technology, the line between the real and the virtual is becoming progressively blurred. We interact with the virtual on a day to day, hour to hour, minute to minute basis -smart phones, software and the web have become a woven and essential part to the way we live.

The Green Bridge concept proposal enabled us to explore basic principles of interaction and communication between the virtual and the physical, which is crucial in realising the possibilities buildings of tomorrow have in responding to their users, to programmatic requirements and to changes in climate throughout any given year.

Our concept proposal for the Green Bridge public artwork in the Gold Coast was the first step in exploring these themes. The video above demonstrates an effort to begin to understand the potential of responsive buildings through exploring one way of interacting with the digital model.

The prototype was developed using an Arduino, an open-source micro-controller, with an ultrasonic sensor for measuring distance. The sensor emits an ultrasound which travels through the air, and if it hits an object it will bounce back to the sensor. The distance is then calculated by considering the speed and travel time of the ultrasound.

 The lighting was intended to be actuated through sensors on the bridge, enabling the bridge to interact and communicate with the heart of the cultural centre, HOTA.

As people cross the bridge to enter the precinct, their movement will create effects through the lights. This acts as a beacon that communicates to those already within the cultural centre that people are entering.

Pedestrians and cyclists pass through a gateway threshold as they approach Gold Coast’s Home of the Arts Precinct. The ribbon like structure wraps around the bridge and continues on overhead to create a sense of welcome, identity and presence.

The artwork aims to form a point of arrival as an activated beacon within the precinct, celebrating the views over the lake towards the HOTA site.

Optimisation of Facade Panels for The Crest Apartments by Daniel Giuffre

The adoption of computational design enables smaller teams of designers to compete with the larger practices, by implementing digital workflows into their everyday. This is also true for fabricators who will inevitable find themselves pressured by demands for realising complex geometry and advances in technology.

Automated Modeling + Drawings from Site Measurements by Daniel Giuffre

if/Lab has created a workflow for automating the modeling and documentation of panels from site measures that saves time and increases accuracy without the need for costly scanning technology- just a pen and a tape measure.

For the Forrest Chase redevelopment in Perth’s CBD, if/Lab has assisted Denmac with the documentation of sheet metal panels by creating a seamless workflow that takes site measurements and outputs models, drawings and laser cutting files.

Shop Drawing Automation with Rhino and Grasshopper by Daniel Giuffre

At if/Lab, digital workflows underpin our daily practice. We are continually looking to develop our tools which include optimising information from digital design models to speed up traditional shop drawing processes and achieve new levels of efficiency and accuracy in the digital design workflow that support the complexities of construction.
