UT Dallas computer scientists have developed a technique to make 3-D images that finds practical applications of a theory created by a famous mathematician. This technique uses anisotropic triangles – triangles with sides that vary in length depending on their direction – to create 3-D “mesh” computer graphics that more accurately approximate the shapes of the original objects, and in a shorter amount of time than current techniques. These types of images are used in movies, video...

MIT team discovers way of making perfectly ordered and repeatable surfaces with patterns of microscale wrinkles. The wrinkles on a raisin result from a simple effect: As the pulp inside dries, the skin grows stiff and buckles to accommodate its shrinking size. Now, a team of researchers at MIT has discovered a way to harness that same principle in a controlled and orderly way, creating wrinkled surfaces with precise sizes and patterns. This basic method, they say, could be harnessed for...
