3D Zoom Method of determining zoom level of visualization system for 3D modeling

摘要

Method and apparatus for determining maximum zoom level of LOD of 3D modeling visualization system. An area of a panoramic image that determines a camera virtual view of a 3D modeling object is variably determined, and a camera virtual view exists in the determined area. When the 3D modeling visualization system is visualized by matching the user virtual view, the camera virtual view closest to the user virtual view is determined, and the maximum zoom level is determined based on the X-Y plane of the corresponding camera virtual view. At this time, the maximum zoom level is higher than the LOD zoom level of other 3D objects nearby.
