Abstract: An input device encodes motion using a laser self-mixing velocimeter. The laser beam is directed at a disk or other moving member. As light from that beam is reflected back into the emitting cavity of the laser, the beam power output fluctuates because of the self-mixing effect and generates a beat signal. The beat signal frequency is used to determine the speed of the member's motion. The direction of motion is also determined based on the beat signal. A difference frequency analog phase locked loop filters the beat signal. A zero-point control disables motion detection when the average beat signal amplitude falls below a threshold. A triangle modulator generates a triangle wave for the laser bias current, with the triangle wave frequency being a submultiple of the beat signal frequency.

Abstract: A method of globally analyzing intersections between objects in computer animation includes providing objects represented by meshes, with each of the meshes being formed by a set of vertices, where a set of pairs of vertices defines a set of edges of the mesh. All edges of the meshes are checked to determine if the edges intersect with any of the meshes.

A polarity of each of the contained vertices is set to indicate that those vertices are contained within the intersection path. The analysis forms the backbone of a collision-response algorithm for unoriented objects such as cloth that is better than previous existing algorithms. The analysis also allows objects to be simulated even when hand-animated elements of the simulation have extreme amounts of interpenetration.

Abstract: A complex procedural surface can be expressed based on some constructive solid geometry operations performed on primitive procedural surfaces. The domain based representation of the complex procedural surface includes implicit curves of intersection. During pre-processing, the parts of the domain based representation to be triangulated are first sub-divided into simple triangles not bound on any side by an edge related to the parameterized regions of the implicit curve and curve visibility triangles. The coarse pre-processed triangulated mesh is later refined during runtime by further sub-dividing the coarse mesh to add triangles with curve based edges and non-curve based edges to generate a mesh of sampling triangles. The more refined sampling triangle mesh is further refined by applying geometry instancing to map appropriate instance meshes into the appropriate sampling triangles to create an even more refined triangulated mesh at runtime for rendering.
