Apparatus and method of providing textured surfaces for computer-generated images comprises embedding a procedural description corresponding to a bit-map representation of a texture in a hybrid file module that also includes the bit-map representation. The hybrid file module may be transmitted to a player over a data communications medium. Once received, the player extracts the procedural description from the hybrid file module, with the procedural description then being used to render the texture.

A video conference method and apparatus for pruning mode commands received from an endpoint of a video conference so as to minimize the repetitive establishment and tearing down of video, audio and data streaming channels is described. Received mode commands are not immediately processed during call establishment of a video conference, but rather, the mode commands are stored in at least one data queue until the second phase of the capabilities exchange (i.e. initialization) is complete. The received mode commands are categorized into mutually exclusive groups of mode commands based upon the functions caused by each mode command. As the system removes the mode commands from the queue for processing, the system efficiently prunes the commands by processing only a selected sub-set of the grouped mode commands and ignoring the rest.

The present invention discloses a method and system for streaming an information stream from a producer to N consumers in a multi-process environment. An inter-process communication (IPC) channel containing a shared memory is provided between the producer and at least one of N consumers. The information stream is written into the shared memory by way of a producer-side interface. The information stream is read from the shared memory by way of a consumer-side interface.

Apparatus and method of rendering a texture comprises computing a set of initial pixels to produce an initial version of the texture, which has a low resolution as compared to a final version of the texture. The initial version is scaled using an algorithm wherein each of the initial pixels corresponds to a group of final pixels. The scaling algorithm creates interpolated values for the final pixels in each group. Actual values for the final pixels are computed following a predetermined ordering in which the final pixels in each group are ordered in accordance with a first pseudo-random sequence, and the groups are also ordered in accordance with a second pseudo-random sequence. The interpolated values of the final pixels are progressively replaced with the computed, actual values to arrive at the final version of the texture. An intermediate version of the texture, which includes the set of initial pixels plus a portion of the actual values computed for the final pixels, is provided to a graphics device for texture mapping in accordance with the progressive rendering process.
