Abstract

The invention provides a vertex recognition method and device in a three-dimensional scene, and the method comprises the steps: carrying out the projection of a target three-dimensional model in the vertical direction, and obtaining a height projection map of the target three-dimensional model; determining a vertex to be rendered from the height projection map, and generating a first vertex set; sequentially checking whether the flatness of the surrounding area of each vertex in the first vertex set meets a condition or not, and deleting the vertexes which do not meet the condition to obtain asecond vertex set; sequentially loading each vertex in the second vertex set, determining other vertexes of which the distances from the current vertex are smaller than or equal to a distance threshold, and removing vertexes with non-maximum height values in a vertex set formed by the current vertex and the other vertexes to obtain a third vertex set; and marking the vertexes in the third vertexset so that the manual discharge work can be saved, and a large amount of manpower consumption is saved.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a method and device for identifying vertices in a three-dimensional scene, a computing device, and a computer-readable storage medium. Background technique [0002] In 3D games, there is a need to recognize the vertices in the scene, such as the spire of the building in the 3D scene. When the protagonist or other characters, such as birds, move to the spire in the animation, it involves the precise positioning of the spire question. [0003] The positioning method in the prior art is to manually calibrate the position of the apex: place markers on the vertices of the 3D model for calibration. This requires manual placement of markers, which consumes manpower. When the scene is very large, there will be a plurality of such spiers that need to be placed and identified in one scene, and the method of the prior art will cause huge manpower consumption.
