Graphics & User Interfaces
In a step toward controlling vibrations, researchers have created an algorithm that automatically optimizes the shape of 2D and 3D objects to control the frequencies and amplitudes of the sounds generated when those objects vibrate.
Deployable 3D Linkages with Collision Avoidance describes a method for creating Hoberman-like mechanisms out of arbitrary 3D models. The method, which requires little user input, automatically avoids collisions among parts so object can expand and contract.
Researchers create an algorithm that computes a reflector shape to boost signals for desired indoor areas while weakening them elsewhere. The reflector can be 3D-printed for $35. Limiting signal coverage also helps prevent nearby cyberattacks.
