A 3D GS scene hybrid rendering method, device, equipment and medium

Abstract

This application provides a method, apparatus, device, and medium for hybrid rendering of 3DGS scenes, including: performing frustum clipping on multiple 3DGS scenes participating in hybrid rendering, and storing all selected nodes to be rendered in a list of nodes to be rendered; splitting each node to be rendered in the list of nodes to be rendered into one or more data segments the size of a tile according to its data size, and writing each data segment sequentially into the free tile of the virtual texture; based on the page table structure, traversing all 3DGS primitives loaded into the virtual texture, and globally sorting them according to the depth value of each primitive to determine the sorting index sequence; according to the sorting index sequence, sequentially accessing the corresponding primitive parameters in the virtual texture, and performing per-primitive rendering in the GPU using a semi-transparent blending method without writing to the depth buffer, thereby solving the rendering problem caused by abnormal sorting of high-order primitives in each scene during multi-scene rendering.
