Abstract: A method and apparatus for rendering shadows. A pre-rendering process implements a two dimensional array or map of depth-based functions, such as a visibility function in z. During rendering of an object scene, these functions are accessed via lookup operations to efficiently determine the function value for a sample point at a given depth. The use of visibility functions allows for partial light attenuation effects. Each visibility function is computed by filtering multiple transmittance functions obtained by casting sample rays from a light source onto an object scene. The visibility function is implemented as a sequence of vertices. Colored shadows are modeled by vertices comprising a depth value and separate visibility function values for red, green, and blue light at a given depth value. Compression is achieved by minimizing the number of vertices needed to represent a visibility function within a desired error tolerance.

Abstract: Accordingly, embodiments of the present invention provide circuits, methods, and apparatus that improve utilization of storage buffers by overwriting data in them as soon as the data is no longer needed. An exemplary embodiment employs a counter to add each time a particular unit of data is needed by a circuit. The counter also subtracts each time the data is actually used by the circuit. When the counter reaches zero, upstream circuitry is checked to see if a command allowing the particular data to be overwritten has been issued. If it has, the command is not waited for, rather the data may be overwritten immediately. Embodiments of the present invention may also make use of one level of indirection to mask physical storage buffer locations from upstream circuitry. In this way, utilization can be improved.

The markers are centering and aligned when the frame/field alignment and the color and/or sample portions of the signals correspond in time. Tabular data, distinct coloring and alarms also are depicted.
