The present invention provides a motherboard that uses a high-speed, scalable system bus such as PCI Express® to support two or more high bandwidth graphics slots, each capable of supporting an off-the-shelf video controller. The lanes from the motherboard chipset may be directly routed to two or more graphics slots. For instance, the chipset may route (1) thirty-two lanes into two ×16 graphics slots; (2) twenty-four lanes into one ×16 graphics slot and one ×8 graphics slot (the ×8 slot using the same physical connector as a ×16 graphics slot but with only eight active lanes); or (3) sixteen lanes into two ×8 graphics slots (again, physically similar to a ×16 graphics slot but with only eight active lanes). Alternatively, a switch can convert sixteen lanes coming from the chipset root complex into two ×16 links that connect to two ×16 graphics slots. Each and every embodiment of the present invention is agnostic to a specific chipset.

A panoramic annular lens system (PAL), a unitary video camera and a PC-based software system that unwraps a 360° video image into a seamless, distortion free horizontal image image in real time. The PAL system of the preferred embodiment has a 360° horizontal field of view and a 90° vertical field of view in a 40 mm diameter compact package. The invention is not limited to any particular type of lens system. In fact, there are numerous lens systems for providing a 360° panoramic view. The video camera may be a CCD or CMOS based device having a pixel resolution of either 1280×1024 (high resolution) or 720×480 (NTSC). The unwrapping system is a radiometric ray tracing program carried out using a computer's graphics card capabilities to produce highly efficient regional transformation while minimizing software overhead. The result is real time, high resolution 30 fps conversion from a spherical distorted image to a flat panoramic image in Cartesian coordinates.

Systems and methods for network transmission of three-dimensional graphical data are disclosed. A single graphical application instance can virtually and efficiently exist on multiple local or remote display systems by directly sharing its raw rendered framebuffer memory information among all local or remote graphics accelerators, thus avoiding the need to re-render any application information again on each node. An internal graphics card is used to scale the rendered data prior to transmission. This graphics scaling eliminates the need for data compression or image compression and achieves an adaptive, hardware-accelerated reduction in network bandwidth. Furthermore, since all memory and remote processing support tasks are performed within the graphics card, the CPU, system bus, and memory bandwidth remain available to the system and other applications.
