SDF used to Deform Geometry

Building upon that collision detection, we can also use the SDF to deform the object upon the collision. Using the SDF value and some math, the grid can be deformed to create footprints stamped on by the Torus.

SDF (Signed Distance Field) used to Detect Overlapping Objects

SDF is short for signed distance field and describes the interior volume of an object. How thick an object is from the middle to the surface? How deep does the cylinder extend? From any point inside an object, using the SDF, it is possible to easily grab the distance to the surface of the object in order to know the depth.
