Problems solved by technology

[0003] At present, the 3D software can complete the action playback of the trajectory of the character animation, which needs to be inserted into the game through a third-party plug-in to complete it, but it is not applicable to transplant the walking trajectory of this character into the game engine developed by itself.
[0004] In the process of realizing the present invention, the inventor found that there are at least defects in the prior art such as cumbersome operation process, high cost and small scope of application.

Embodiment Construction

[0036] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0037] A Bézier curve is an approximation-based parametric curve that seems to be defined by a set of Bézier characteristic polygons, and a Bézier curve is always done through the first and last control points. The start point and end point of the curve coincide with the view point and end point of the polygon, and the multi-expression first side and last side represent the tangent vector direction of the curve at the start point and end point respectively. The shape of the curve tends to be a polygon, and the polygon can be defined by its vertices. These vertices are called control points. As long as the control points are given, a Bezier curve can be generated.

Abstract

The invention discloses a method for achieving role treading track animation by using Bezier curve. The method mainly includes: storing animation object parameters into one or more animation channels; in each animation channel, setting a series of key frames for the animation to impel the motion state of the animation in the default time; performing interpolation calculation among the animation key frames in each channel, thus enabling a role to walk along an appointed curve, and thereby forming a vivid role animation effect. The method for achieving role treading track animation by using Bezier curve can overcome the defects that the prior art is tedious in operating process, high in cost and small in application range, thus achieving the advantages of concise operating process, low cost and wide application range.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for realizing animation of a character's walking track by using a Bézier curve. Background technique [0002] Computer animation integrates computer graphics, especially realistic graphics generation technology, image processing technology, motion control principles, video display technology, and also involves robotics, artificial intelligence and other fields. At present, it is more used as a comprehensive application of computer graphics. In computer animation, it is necessary to design the motion trajectory of objects, and it is the same in games, in order to express smooth curved motion. [0003] At present, the 3D software can complete the motion playback of the trajectory of the character animation. It needs to be inserted into the game through a third-party plug-in to complete it. However, it is not applicable to transplant the walking trajectory of this character into th...
