Abstract: A method for providing a beveling effect to a video polygon a second polygon is generated in a plane parallel to the first polygon. The second polygon is an expanded copy of the first polygon. Vertices of the first polygon are connected to corresponding vertices of the second polygon according to a predetermined beveling function.

Abstract: A method of and apparatus for enhancing an audio signal to reflect positional information of a sound emitting object in a simulation are described. The method includes determining a parameter describing a location of the sound emitting object. A setting for the audio signal is adjusted based on the first parameter by sending an adjustment command to an audio interface device. Either the whole audio signal, or a portion thereof is transferred to the audio interface device after the adjustment command. The apparatus includes a processor, a memory, and an audio interface coupled to a bus. The memory contains an audio adjustment routine which, when executed by the processor, sends an adjustment command to the audio interface device to adjust a characteristic of an audio signal. The adjustment command reflects a spatial location of an emitter in a simulated environment.

Abstract: A browsing system for multimedia uses a polyhedron to display multiple multimedia sources simultaneously. A user or software can rotate the browse polyhedron to make visible faces of the polyhedron which are hidden and can rotate the polyhedron to change the orientation of visible faces. On each face, the system renders a different video stream from the multimedia data source based on the orientation.

Abstract: A real-time media driver for scheduling and mixing media in a multimedia environment. Implemented to operate in conjunction with a non-real-time operating system, the real-time media driver comprises a wave driver which controls a predominant percentage of the operations of the media hardware device and a mini-device driver which is software provided by the vendor of the media hardware device to support functions unique to the particular media hardware device. Furthermore, the real-time media driver comprises a media scheduler which (i) synchronizes multiple media streams prior to being input into a mixing/splitting device of the media scheduler; (ii) allows reconfiguration of attributes of media streams without loss of content prior to and after operations by the mixing/splitting device; and (iii) appropriately mixes media to produce multi-channel media according to a certain "prioritized sharing" policies.
