Problems solved by technology

Usually the start and end actions are different between two different animations. If the above-mentioned "snapshot and replace" transfer behavior is used, the end action of the first animation is directly transitioned to the start action of the second animation without intermediate transitions. Movements, prone to incoherence between movements

Embodiment Construction

[0022] The specific structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] The smooth transition method between the animations of the present invention refers to that in the animation production process, the last posture (end posture) of the previous action and the beginning posture (starting posture) of the next action are connected together, so that the transition between the two actions can be achieved. smooth transition between.

[0024] Such as figure 2 As shown, the smooth transition method of the present invention is realized through the following steps:

[0025] (a) Obtain the bone position value of the last pose of the previous action, represented by matrix Matrix1; and the bone position value of the start pose of the next action, represented by matrix Matrix2;

[0026] (b) The posture matrices Matrix1 and Matrix2 of the above two actions are disassembled into three components of scaling (Scaling1,...

Abstract

The invention discloses a method for realizing smooth transition among animated cartoons, which comprises the steps: (a) respectively getting a last posture matrix of a previous action and a beginning posture matrix of a next action; (b) respectively disassembling the posture matrixes of the two actions into three components: zooming, rotation and translation; (c) carrying out interpolation calculation on the three components of zooming, rotation and translation to obtain new components of zooming, rotation and translation; (d) integrating the components of zooming, rotation and translation obtained after interpolation calculation into a posture matrix of a middle action; and (e) applying the posture matrix of the middle action into action postures for smooth transition. The method has the obvious characteristic that animated cartoons do not get distortion in middle transition and have a coherent and smooth transition effect.

Description

technical field [0001] The invention relates to computer image processing technology, in particular to a method for realizing smooth transition between animations. Background technique [0002] In the animation design process, we can regard character animation as a sequence of key actions of a character, and the key actions created by motion capture or human hands have different starting poses and ending poses. Therefore, the smooth transition technology between animations is to achieve a coherent and smooth transition effect between key actions. In the prior art, the computer can be used to calculate the transition animation between the two actions based on the start and end postures of the key actions of the character, so as to realize the smooth transition between the animations. [0003] If you need to smoothly transition from one animation to another, interpolate the bone position of the current action and the bone position of the next action, and then calculate the in...
