Abstract

The invention discloses a cross-layer scheduling method and system for rendering a 3DTiles model based on OSG, and electronic equipment. The method comprises the following steps: loading 3DTiles model data; in an OSG frame cycle, aiming at each frame in the 3DTiles model data, updating a loadable model rendering state set in a viewport; and setting rendering state attributes according to the types of the model nodes in the loadable model rendering state set, and adding the model nodes with the set rendering state attributes into a rendering queue. According to the method, when the OSG loads the 3D Tiles model data, the child nodes and the father nodes are loaded at the same time by updating the loadable model rendering state set in the viewport and setting the rendering state attributes, the loading and rendering display speed of the 3D Tiles model data in the OSG is increased, the model display effect is smoother, and the user experience is improved. And the problem that data of the child node model and the father node model are mutually overlapped and influenced when being loaded at the same time is solved.

Description

technical field [0001] The invention relates to the field of OSG three-dimensional rendering, in particular to a cross-layer scheduling method, system and electronic equipment for rendering 3DTiles models based on OSG. Background technique [0002] When loading models in the traditional OSG (OpenSceneGraph) 3D rendering engine, layered loading is achieved through LOD (Levels of Detail, multi-level of detail), but the data loading of LOD nodes will be slow due to network speed or system scheduling problems, and the scheduling of parent nodes When rendering data with child nodes, the replacement of the LOD parent node is to wait for all its child node data scheduling to be completed before loading the child nodes at one time, and then replace the parent node, resulting in slower scheduling and rendering speed. [0003] Moreover, even if the parent node and the child node are loaded at the same time, because the LOD level of the parent node and the child node are different, the...
