Three-dimensional stretching modeling method and device

Abstract

An embodiment of the invention relates to a three-dimensional stretching modeling method and device and solves a problem that modeling methods of a majority of modeling software are comparatively complex in the prior art. The method includes determining the shapes of a basic two-dimensional image input by a user and the relative position of the two-dimensional image in a three-dimensional model to be established; determining a plurality of vertexes of a triangular sheet according to the shape of the three-dimensional model to be established, the shape of the basic two-dimensional image and two-dimensional data points constituting outline of the basic two-dimensional image; connecting the vertexes to be connected among all the vertexes to form a plurality of triangular sheets, so that the three-dimensional model is established. By adopting the three-dimensional stretching modeling method, the required three-dimensional model can be established with the single basic two-dimensional image and does not need to be formed by the combination of basic three-dimensional models preset in software. Therefore, the implementation method for three-dimensional stretching modeling becomes simple.

Description

technical field [0001] The invention relates to the field of three-dimensional modeling, in particular to a method and equipment for three-dimensional stretching modeling. Background technique [0002] In a 3D scene, all 3D primitives can be split into basic graphic structures, such as a cylinder can be split into two discs and a circular surface. And each basic graphic structure can be split into triangular faces one by one. [0003] In most 3D modeling software, there are basically many basic model structures, including 2D models (such as discs, rectangles, curved surfaces) and 3D models (such as spheres, cuboids, cylinders), and then Scaling, splicing, or merging operations are performed on these basic 3D models, and then combined into various 3D models, and the implementation of modeling is relatively complicated. This modeling method can basically complete most of the modeling work, but it is very inconvenient to operate. It is necessary to adjust the parameters and p...
