Enrico Dini: Large Scale (6m x 6m x 1m) 3D Printing

May 7th, 2009 No Comments

Large scale 3D printing using sand and epoxy resin. The results resemble sandstone, with strength comparable to reinforced concrete. The process sounds simular to the way Zcorp printers work, though with a different scale & resolutions (25 DPI).

Rheoscopic Resources

May 5th, 2009 No Comments

Rheoscopic fluids allow you to current flows — think of a bottle of pearlescent shampoo.
Paul Matisse created a number of Kalliroscopes, which use rheoscopic fluid to display fluid flow.  Info on Matisses’s work, and has rheoscopic fluid for sale.

Smoothstep interpolation for motion control

March 8th, 2009 No Comments

“Adding little smoothness to all kinds of movement, be it actual movement of the camera, some object, fading of lights, fading in and out etc, makes things much more enjoyable to watch. Sharp movements and changes are jarring and should be avoided.

For example, X ranges between points A and B in N steps.
With linear interpolation:
