Abstract: Embodiments of the present disclosure provide a method and apparatus for data scheduling based on ray tracing, a system, a device, a storage medium, and a computer program product. The method comprises: determining a first target storage block in a first memory and a target storage block group in a second memory, the first target storage block and the target storage block group respectively storing ray data and block data having a correspondence relationship; reading the ray data from the first target storage block; and reading the block data from the target storage block group in two scheduling cycles, said data read scheduling using write-priority mode in the first scheduling cycle and read-priority mode in the second scheduling cycle, respectively.
