Motion editing method based on four-dimensional spherical trajectory

Abstract

The invention discloses a motion editing method based on a four-dimensional spherical trajectory. The motion editing method include selecting a high-level semantic feature, namely a skeleton rotation direction, of a motion as a feature of an editing algorithm to input, and mapping a variable domain of the feature to the continuous four-dimensional spherical trajectory to perform parameter editing to realize style editing of motion capture data. The motion editing method has the advantages that conciseness, visualization and high efficiency are realized; animators can create animation products with unique styles on the condition of selecting proper skeleton and curve parameters by the method, and workload is lowered; through correction of displacement data of root joints of the whole global schedule, a root joint motion trajectory of a human body conforms to physical laws, so that the problem of motion distortion in existing correction algorithms is solved.

Description

technical field [0001] The invention belongs to the technical field of motion capture, in particular to a motion editing method based on a four-dimensional spherical trajectory. Background technique [0002] In recent years, the animation industry represented by animation, comics, and online games has become a new economic growth point in developed countries. The world's animation industry is mainly concentrated in Europe, America, Japan, and Korea. The United States is one of the earliest and major developing countries. Its animation industry has taken the lead in the global animation industry; Japan, as a major exporter of animation products, occupies an important position in the international market with its strict industrial chain structure and mature operating mechanism. In developed countries, the animation industry is not only important, but also It is one of the pillar industries, and the total annual market is tens of billions or even hundreds of billions of dollars...
