Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] like Image 6 The illustrated embodiment is a motion controllable shape interpolation method comprising the following steps:

[0042] Step 100, isomorphic triangulation generation of source shape and target shape

[0043] given a figure 1 A source shape and a target shape are shown, the user places polygonal boundaries on the source shape and the target shape respectively, and uses the isomorphic triangle algorithm to generate a pair of isomorphic triangulations for the source shape and the target shape. The isomorphic triangulation contains the source triangle mesh The lattice and the target triangular mesh, the vertices of the triangular mesh and the target triangular mesh have one-to-one correspondence, and have the same connection edge structure;

[0044] Among them, the source triangle mesh covers the source shape, and the target...

Abstract

The invention discloses a motion controllable shape interpolation method. A source shape and a target shape are given. An initial shape transition sequence is generated by using a shape interpolation method based on triangularization. A local or global skeleton is defined on the source shape by the user, and the corresponding skeleton position is automatically derived for the intermediate transition shape and the target shape. The skeleton is edited on any transition shape by the user, and the skeleton change is enabled to automatically work on the whole transition sequence by the algorithm so as to generate the required motion dynamic. The simple and visual motion attitude control method is provided, and the user is allowed to edit the motion attitude in the whole shape transition sequence through simple skeleton operation so as to generate the more vivid animation sequence.

Description

technical field [0001] The invention relates to the technical field of two-dimensional character animation, in particular to a motion-controllable shape interpolation method. 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, it takes a lot of time and high production cost to produce 2D animation by traditional hand-drawn methods. Many 2D commercial animation software have been developed at home and abroad, such as Adobe Flash, Toon Boom Studio, etc., to assist in the production of 2D animation. 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 digital board, so as to facilitate the editing and management of materials. However, animators still need to draw 2D a...
