A versatile approach to assist animators in enhancing their craft.

MIT researchers have developed a technique that might allow animators to have more control over their creations. It leverages mathematical functions known as barycentric coordinates to define the way 2D and 3D shapes bend, stretch and move. It gives artists significant flexibility, allowing them to select functions that best fit their vision for the animation.…

A versatile answer designed to assist animators in enhancing their artwork.

Researchers from MIT have developed a method that could provide animators with greater control over their animations. This new technique generates mathematical functions known as barycentric coordinates, which define how 2D and 3D shapes can bend, stretch, and move through space. This allows the artist to determine the movements of animated objects according to their…

An adaptable approach designed to assist creators in enhancing their animation skills.

MIT researchers have developed a technique that could revolutionize the animation industry by giving artists more flexibility in how they animate characters. Instead of sticking to a single conventional measurements or mathematical functions called barycentric coordinates, the new method allows the artist to experiment with different movements and expressions, specific to each individual animation. This…

A computer scientist advances the limits of geometry.

Over two thousand years ago, Greek mathematician Euclid revolutionized the world with his groundbreaking work in geometry. Today, MIT Associate Professor Justin Solomon is using contemporary geometric techniques to solve intricate problems, which often don't appear to be related to shapes, albeit heavily correlate with data arrangement in a high-dimensional space. Solomon, who is also a…
