Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0039] Such as Figure 4 The illustrated embodiment is a line shape correspondence method considering the local topology, comprising the following steps:

[0040] Step 100, based on the local topology of the relative positional relationship of the lines

[0041] Such as figure 1 As shown, given two line shapes, called source shape and target shape respectively. where the source shape consists of a set of lines, let The target shape consists of a set of lines, let

[0042] Step 110, for each line in the source shape If another line in the source shape If its distance is less than a given threshold, the default value of the threshold is 18, it is called a line for lines Neighborhood lines, also known as lines The set of all neighborhood lines of is the line The local neighborhood of ; according to each line in the source shape ...

Abstract

The invention discloses a line shape corresponding method considering local topological structures. Two planar shapes formed by lines are given, the one-to-one corresponding relationship between linesof the two shapes is automatically established, and the local topological structures of the shapes are considered in the corresponding process. The method is advantaged in that corresponding accuracyof the lines of the shapes is substantially improved, and a line shape corresponding problem is lastly solved.

Description

technical field [0001] The invention relates to the technical fields of two-dimensional character animation technology and two-dimensional line shape interpolation, in particular to a line shape correspondence method with good practicability considering local topological structure. Background technique [0002] With the strong support of the government, the domestic animation industry has developed rapidly in recent years, and the output of animation has also increased significantly. However, traditional hand-drawn 2D animation requires a lot of production time and high production costs. In order to assist the production of 2D animation, many commercial software for 2D animation production have been developed at home and abroad, such as Adobe Flash, Toon Boom Studio, etc. These commercial software mainly implement the so-called "paperless cartoon" function, that is, to convert the traditional animator's drawing on paper to let the animator draw on the computer through the d...
