Blog: 2012-05-27. With the arrival of the Nvidia GTX 680, more things opened up for us on our journey to have real-time graphics that are astoundingly believable and impressively immersive. The Nvidia's Kepler GTX 680: Powering the Next Gen article on GameSpot by Mark Walton does a great job of bringing us the videos and info behind the scenes. First up, I really love this image of the GTX680 die, gorgeously techie. [Nvidia GTX680 die via Gamespot] Here are the 3 videos from the article, first Unreal's demo of some wonderful facial and character goodies as part of a full sequence that really shows where we are at with respect to real-time cinematics.
Paper Foldings by Andrea Russo. Italian paper artist Andrea Russo has generated numerous beautifully textural paper foldings that dabble with a van Gogh portrait, some pendant lampshades, origamic cylinders and arm accessories. Check out these picks taken from Andrea’s Flickr set: pendant lampshades van Gogh origami portrait You can view Andrea’s extensive portfolio on his Flickr page: Andrea Russo. Polyscene's Photostream.
Digital Fabrication: Parallel Pleat Forms | Smart Art. As part of a four person team, I have been exploring parallel pleats to create forms that will aggregate into a "big" self standing structure. This class, taught by Maciej Kaczynski, is linked to generative computing (taught by Glen Wilcox). Some previous blog posts look at the work being done in that class. Our team has been looking at parallel pleats to create hyperbolic paraboloids (aka Hypar, although Dr. Demaine at MIT has written a paper on the true nature of these forms) that will vary in size and/or shape to aggregate into this self standing structure. Cameron Stewart, one of the team members, put together this (beautifully made) presentation of the models we designed and created as test studies.
Since the previous week we had heavily focused on general forms and plastic options, we decided to look more specific at the form options available from parallel pleats of octagons and by shared edges.

Hi everyone, I would like create some grasshopper definitions of paper models that we are making by hand and to be able to change them in 3D (and compare the results) by changing the 2D geometry (the unfolded pattern). I think I would like to achieve something like the software Rigid Origami does, but using Rhino+Grasshopper instead.
Although being an architect myself I am a beginner in Grasshopper and therefore I would like to ask you for some advice on where to start, how to define the paper folding behavior in GH. I am doing some research into paperfolding and make paper models with the students at the Brno University of Technology Faculty of architecture: I found this website of Tomohiro Tachi very inspirational, especially this article: Thank you. Jiri. Matthew Shlian. Matthew Shlian works within the increasingly nebulous space between art and engineering. As a paper engineer, Shlian’s work is rooted in print media, book arts, and commercial design, though he frequently finds himself collaborating with a cadre of scientists and researchers who are just now recognizing the practical connections between paper folding and folding at microscopic and nanoscopic scales.
(via The Ghostly Store) Hyperbolic Paraboloids | denise. Erik Demaine, Martin Demaine, and Anna Lubiw A hyperbolic paraboloid is an infinite surface in three dimensions with hyperbolic and parabolic cross-sections. A couple of ways to parameterize it and write an equation are as follows: z2 = x2 – y2 orx = y z The plots shown to the right use the first equation. Hypars We use the term hypar to mean a hyperbolic paraboloid shape, or more formally a partial hyperbolic paraboloid, cut from the full infinite surface. We are particularly interested in how hypars can be joined together at their edges to make interesting sculpture.
Hypars in Architecture Hypars and joining hypars in a few special ways have been used extensively in architecture. Folding Pleated Hypars It is amazingly easy to fold a hypar from a square piece of paper. More detailed diagrams are available. Hats There are many ways to glue hypars together edge-to-edge. In particular, you can close a k-hat up onto itself to make a k-star. Hyparhedra Like this:
