Embodiment Construction

[0039]The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] Such as figure 2 , image 3 The illustrated embodiment is a structure-preserving two-dimensional shape interpolation method, including two source shapes and target shapes that are respectively composed of lines and are stored in a computer. Both the source shape and the target shape are two-dimensional shapes; Inserting a transition shape between the source shape and the target shape includes the following steps:

[0041] Such as Figure 4 as shown,

[0042] Step 100, constructing a source space frame and a target space frame corresponding to the source space frame:

[0043] set in computer is the set of corresponding lines in the source and target shapes, be the lines in the source shape, for the target shape and The corresponding line, i is the serial number of the line in the source shape and the target shape;

[0044] Ste...

Abstract

The invention discloses a structure-preserving interpolation method of two-dimensional shapes. The structure-preserving interpolation method comprises the following steps: respectively arranging two-dimensional shapes such as a 'source shape' and a 'target shape' in a computer; firstly, introducing a simple structure to represent the space layout relation between adjacent lines in the source shape, and naming the structure as a 'source space frame'; similarly, adopting similar structures to represent the space layout relation between adjacent lines in the target shape, and naming the structure as a 'target space frame'; and then interpolating the source space frame to the target space frame, and finally realizing natural transition from the source shape to the target shape. The structure-preserving interpolation method disclosed by the invention has the characteristic that not only can significant geometrical features of single lines be maintained, but also the space structure relation between the adjacent lines can be maintained, so that the semantic features of the source shape and the target shape can be maintained in a transition shape sequence, and finally a visually-beautiful shape transition sequence is generated.

Description

technical field [0001] The invention relates to the technical field of two-dimensional animation, in particular to a structure-preserving two-dimensional shape interpolation method capable of maintaining shape feature semantics. Background technique [0002] With the development of digital media technology, many digital entertainment applications have emerged, such as movies, networks, games and so on. Two-dimensional animation is an important content in these applications. Therefore, in order to further promote and popularize these applications, it is necessary to design and provide corresponding tools so that users can intuitively and quickly produce desired 2D animations. [0003] Two-dimensional shape interpolation is an important technique in the field of computer animation. Given the shapes of any two adjacent key poses of an object (referred to as the source shape and the target shape), the technique obtains intermediate poses between key poses by automatically gene...
