Prisms. A prism is a 3D shape which has a constant cross section - both ends of the solid are the same shape and anywhere you cut parallel to these ends will give you the same shape.. For example ...

In a cross-section of a chambered shell, the segmented shapes appear to have corners, but the 3D geometry of the chambers does not have any. Krisztina Regõs and Lajos Czegledi. The team ...

But 3D shapes with curves can fill space, ... Zebra stripes, river estuaries, cross sections of onions, seashells, heads of wheat, red blood cells, plants and fungi all resembled 2D soft cells.

For the last three decades, biologists and computer scientists have dedicated significant effort to quantifying the 3D shape of cells and analyzing their interactions.

3D printers build objects by cross-section, one layer at a time from the ground up—gravity is the limiting factor. But what if it wasn’t? Using proprietary 3D printing materials, Petr Novikov and Saša ...

Using a photolithography process, scientists have created flat polymer sheets that bend themselves into three-dimensional shapes when exposed to water.

This Stanford team is working on a way to display 3D information, like in a CAD or modeling program, ... allowing more complex shapes, like moving cross-sections, to be expressed as well.

Shape-programmable 3D microfluidic structures formed from a bilayer of PDMS/SMPs. (A) ... “Box” structure, with optical and SEM images of the cross section of the SMP/PDMS interface. Scale bars for ...
