Data processing method and device for three-dimensional model and electronic equipment

The invention is applicable to the technical field of three-dimensional model data display, and provides a three-dimensional model data processing method and device and electronic equipment. The method comprises the steps that a first thread determines a to-be-displayed scene model and a model file corresponding to the to-be-displayed scene model according to position information of a current viewpoint; according to the visual cone of the current viewpoint, performing visibility judgment on all nodes in the to-be-displayed scene model, marking a visible node entering the visual field range ofthe visual cone of the current viewpoint, and mounting the visible node to a detail level paging PageLOD; traversing visible nodes mounted on the detail level paging PageLOD, reading LOD models of different levels, performing LOD visibility judgment on the visible nodes mounted on the PageLOD, and storing data request information into a data request list according to a judgment result; and enabling the second thread to lo
