Abstract

The invention discloses a method for rapidly constructing a complex polygon plane based on Unity 3D, and the method comprises the steps: S0, selecting any vertex of the vertexes of the polygon plane,numbering all the vertexes in sequence, and entering the step S1; S1, judging the convexity and convexity of a polygon plane, classifying polygons, and then entering the step S2; S2, performing triangulation on the polygonal plane to generate a triangular plane (including position coordinates and vertex serial numbers), and then entering the step S3; and S3, carrying out plane filling according tothe generated triangle position coordinates and the vertex serial numbers, and finally a complex polygon plane is obtained. According to the method provided by the invention, the construction of a complex polygon plane can be simplified, manual triangle division is not needed, and the efficiency of Unity 3D modeling is improved.

Description

technical field [0001] The invention relates to the field of modeling, in particular to a method for quickly building complex polygonal planes based on Unity3D. Background technique [0002] With the development of 3D modeling technology, 3D models are indispensable in digital cities, augmented reality, game development and other fields. In practical applications, 3D models are becoming more and more complex, and building 3D models requires a lot of manpower and time costs. In the process of building a model in Unity3D, the first consideration is how to build a complex polygonal plane. The traditional method is to artificially triangulate the polygon, and then use Unity3D to fill the triangle surface to construct a polygon plane. Therefore, the traditional method of building complex polygonal planes based on the Unity3D platform is not only inefficient, but also has error-proneness for triangulation of complex polygonal planes. [0003] Faced with the increasing demand for...
