Metaballs
Metaballs, not to be confused with meatballs, are organic looking squishy gooey bl obs. From a mathematical perspective they are an iso-surface. They are rendered using equations such as f(x,y,z) = r / ((x - x0)2 + (y - y0)2 + (z - z0)2). Jamie Wong has a fantastic tutorial on rendering metaballs with canvas. We can replicate the metaball effect using CSS & SVG by applying both blur and contrast fi

Computational Design of Mechanical Characters
We developed an interactive design system that allows non-expert users to create animated mechanical characters. Given an articulated character as input, the user iteratively creates an animation by sketching motion curves indicating how different parts of the character should move. For each motion curve, our framework creates an optimized mechanism that reproduces it as closely as possible. The r
