Three-dimensional engine boundary limiting method and device based on meta universe and storage medium

The invention relates to the technical field of three-dimensional engine meta-universe models, in particular to a meta-universe-based three-dimensional engine boundary limiting method and device and a storage medium, and the method comprises the steps: reading the grid attributes of a to-be-detected model, carrying out stroke processing, obtaining all vertexes, and forming a vertex set; traversing the vertex set, converting all vertex coordinates into world coordinates, projecting all world coordinate vertexes to the ground to obtain projection coordinates, and forming a stroking dot matrix; acquiring a central point projection point of the to-be-detected model; taking a central point projection point of the to-be-detected model as a plane coordinate central point, and calculating a slope and a distance relative to the plane coordinate central point according to projection coordinates of points in the stroking dot matrix; under the same slope, selecting a projection coordinate which is farthest from the centr
