In accordance with the teachings of the present invention, a method for selecting a server to provide content to a client is presented. A media controller receives a request from a client for content. The media controller instructs a plurality of servers each storing the content required by the client to perform a bandwidth measurement referred to in the disclosure as a bandwidth probe. The result of the bandwidth probe is communicated to the media controller. The media controller selects a server (i.e., an identified server) for communication with the client based on the result and communicates the selection in the form of a redirect command to the client. The client then communicates directly with the identified server.

A method for performing layout verification involves identifying feature centerlines in a mask layout, and then performing lithography simulation along the centerlines to generate a set of intensity distributions. At each local maxima or minima in the intensity distributions, further lithography simulation can be performed to determine an exposure pattern width at those local maxima / minima (check positions). The exposure pattern widths can then be evaluated to determine whether an actual pinch or bridge defect will be generated at those locations. If defect generation is likely (based on the lithographical simulation) at a particular location, the corresponding portion of the mask layout can be redesigned to avoid defect generation during actual production. In this method, accurate layout verification can be performed with a minimum of time-consuming lithography modeling.

Simulating dynamics (e.g., physical effects of inertia, forces, wind) on strands (e.g., hair) during computer based animation requires quick and accurate approximations of mathematical curves. Each strand is initially represented as a B-spline curve. Line segments approximating the curve are created by using affine combinations based on the curve's control vertices. Dynamics simulation is performed on the line segment approximation. Once an approximated strand is simulated, it is converted back into a B-spine curve representation for downstream processes, such as rendering. The rendering process displays the simulated strand to the animator.
