KMODDL - Kinematic Models for Design Digital Library. How-To: Mix and Mold GFRC. Concrete, as most folks know, is strong under compression but weak under tension, and is commonly strengthened by casting it around, e.g. a grid of steel reinforcing bar (“re-bar”).
Glass Fiber Reinforced Concrete is, well, pretty much exactly what it sounds like: concrete reinforced with glass fibers. As in most composite materials, the fiber elements in GFRC can be carefully oriented, or randomly distributed, in the solid matrix. The nice thing about the latter method is that you can just mix the reinforcing fibers into the bulk concrete and don’t have to pre-position them in the mold.
GFRC concrete panels can be much thinner and lighter than metal-reinforced slabs, and the glass fibers are not subject to corrosion. If you’re interested in experimenting with GFRC, however, you may have noticed that practical how-to information is a bit scarce online. In the first, Brandon details three different concrete mix recipes used in the casting of a GFRC bathroom counter with integral sink. Digital Wood Joints. Wood Joints are fascinating!
They embellish old furniture and wood constructions of ancient Japanese temples alike. Everytime we come across them, we are filled with admiration: Admiration for the skill of the master craftsman, as their creator, but also admiration for the balance between function and beauty, which turns the furniture or temple into a work of art. With the onset of industrialisation, the traditional wood joints have been banned more and more to the background. Manufacturing has to be above all efficient, so there is no more room for traditional wood joints. Or is there? As computer-controlled wood processing machines move into the cabinet-makers' workshops, the way two pieces of wood are joined together in a construction needs to be reconsidered. The result of this research are 50 digital wood joints, divided into frame joints, board joints and carcass joints.
We are looking forward for the submission of your modifications and pictures of implementation.
Metal. Woodworking. Plastics. ICT Graphics Lab. Live 3D Teleconferencing Introduction: The Graphics Lab at the University of Southern California has designed an easily reproducible, low-cost 3D display system with a form factor that offers a number of advantages for displaying 3D objects in 3D.
The display is: autostereoscopic - requires no special viewing glassesomnidirectional - generates simultaneous views accomodating large numbers of viewersinteractive - can update content at 200Hz The system works by projecting high-speed video onto a rapidly spinning mirror. While flat electronic displays represent a majority of user experiences, it is important to realize that flat surfaces represent only a small portion of our physical world. Abstract: We describe a set of rendering techniques for an autostereoscopic light field display able to present interactive 3D graphics to multiple simultaneous viewers 360 degrees around the display.
