Abstract (en)
[origin: WO2005078665A1] The invention relates to a device for the photorealistic representation of dynamic complex three-dimensional scenes by means of ray tracing. Said device comprises at least one programmable ray tracing processor in which are implemented: special traversing commands; and/or vector arithmetic commands; and/or commands for establishing ray tracing acceleration structures; and/or at least one decision unit (mailbox) which prevents objects or triangles that have already been intersected by a beam during launching thereof when performing ray tracing from being intersected several times by said beam. The inventive device is organized such that several threads can be processed in parallel and several threads can automatically be processed in a synchronous manner, the device being provided with an n-level cache hierarchy and/or virtual memory management and/or a direct link to the main memory.
