Sketching Dynamic Geometry

Lately, I’ve been exploring the intersection between sketching, coding, and parametric modeling.  I’ve been working on an app for the iPad that relies on some interactions that will hopefully lead to a balance between “manual” and parametric modeling.

Grasshopper and SketchUp are two of my favorite design applications, so, if you know those beautifully crafted softwares, you will see where I’m going with this.  At this point, I’ve only just scratched the surface, and I thought I’d share a little bit of what I’ve been up to…

More to come.

ARchitecture Hall

architecturedemoARchitecture Hall is an interface in which Augmented Reality meets Building Information Modeling.  I created during (around June 2007) of my MS in Design Computing in the Design Machine Group, in the College of Architecture and Urban Planning at the UW.  It is intended to be a simple, intuitive, Tangible User Interface with a MagicLens for viewing BIM models interactively.  It was published in and presented at eCAADe 2008 in Antwerp, Belgium.

The interaction was quite fluid and the polygon count very high: somewhere around 200,000 polygons displayed at 30 fps.  Multiple stencil-buffers were employed for the lens effect (thanks to Julian Looser for his inspiration on this one).   A simple Head’s Up Display (HUD) allows the user to toggle layer visibility.  Check out this video of the basic interaction…


MxR Architecture

mxr-figure02MxR Architecture, my MS thesis project, mixes physical and virtual models together in a single interface. Using Mixed Reality, virtual models can be superimposed over real models in real-time, allowing the designer/user/client to make changes, simulate sun angles, run agents studies, add components as well as transition to a fully-immersive VR view at any time.

Check out the this video for the basic interaction…


MxR – pronounced “mixer” – is a Mixed/Augmented Reality system intended to support collaboration during early phases of architectural design.  MxR allows an interdisciplinary group of practitioners and stakeholders to gather around a table, discuss and test different hypotheses, visualize results, simulate different physical systems, and generate simple forms.  MxR is also a test-bed for collaborative interactions and demonstrates different configuration potentials, from exploration of individual alternatives to group discussion around a physical model.  As a MR-VR transitional interface, MxR allows for movement along the reality-virtuality continuum, while employing a simple tangible user-interface and a MagicLens interaction technique.
