贴图延迟渲染的数据驱动方法及装置
摘要：
一种贴图延迟渲染的数据驱动方法及装置，其中，该方法包括：在移动设备构建渲染对象的层次Z缓冲数据(S202)；将所述层次Z缓冲数据传输至所述移动设备的贴图存储区的层次Z缓冲区中(S204)；将所述层次Z缓冲数据从所述贴图存储区传输至所述移动设备的图像处理器GPU(S206)；在所述GPU中基于所述层次Z缓冲数据对所述渲染对象进行视锥体剔除和/或遮挡剔除，得到贴图数据(S208)；将所述贴图数据从所述GPU传输至所述贴图存储区的可见缓冲区中(S210)。解决了相关技术在贴图延迟渲染时系统内存占用和带宽开销过大的技术问题，均衡了GPU驱动通道中的内存分布，提高了整个GPU驱动的数据传输速度和画面渲染速度。
摘要（英）：

A data driving method and apparatus for tile based deferred rendering. The method comprises: constructing hierarchical‑Z buffer data of an object to be rendered at a mobile device (S202); transmitting the hierarchical-Z buffer data to a hierarchical-Z buffer area of a tile memory area of the mobile device (S204); transmitting the hierarchical-Z buffer data from the tile memory area to a graphic processing unit (GPU) of the mobile device (S206); performing view frustum culling and/or occlusion culling on said object on the basis of the hierarchical-Z buffer data in the GPU to obtain tile data (S208); and transmitting the tile data from the GPU to a visibility buffer area of the tile memory area (S210). The technical problems in the related art of system memory occupation and overlarge bandwidth overhead during tile based deferred rendering are solved, memory distribution in a GPU driving channel is balanced, and the data transmission speed and picture rendering speed of the entire GPU driving are increased.
