Automatic generation method of 2D animation based on skeletal action library

Abstract

The invention discloses a method for automatically generating two-dimensional animation based on a skeletal action library. The steps include: creating bones and skeletal actions and saving them in the skeletal action library; drawing animation shapes, and drawing modeling graphics according to the appearance requirements of the shapes; binding Skeletal actions and modeling graphics, call the skeletal actions from the skeletal action library, bind the skeletal actions and modeling graphics, map the skeletal actions to the modeling graphics; animation interpolation, interpolate the skeletal action frames according to the animation requirements, and obtain the animation sequence. Through the above method, the method for automatically generating two-dimensional animation based on the skeletal action library provided by the present invention improves the efficiency and quality of two-dimensional animation production and effectively saves production costs.

Description

technical field [0001] The invention relates to a method for generating animation, in particular to a method for automatically generating two-dimensional animation based on a skeleton action library. Background technique [0002] Different from traditional vertex animation, skeletal animation is a computer 3D animation that drives the movement of 3D vertex mesh models through moving "skeletons". It takes the skeleton as the research object, extracts the data of the individual's bone motion characteristics and the uniqueness of its motion, uses the skeleton to drive the muscles, and determines the motion trend of the simulated individual. [0003] However, the defects of the skeletal animation technical scheme in the current two-dimensional animation production process mainly lie in the following points: 1. The role of the skeleton as the driver of the modeling movement cannot be brought into full play, and because it is used as an adjustment tool, it cannot Saving the adjus...

Problems solved by technology

[0003] However, the defects of the skeletal animation technical scheme in the current two-dimensional animation production process mainly lie in the following points: 1. The role of the skeleton as the driver of the modeling movement cannot be brought into full play, and because it is used as an adjustment tool, it cannot Saving the adjustment process of the bones will not be able to guide and refer to the modeling actions of the bones, which is a waste of the use of the principles of skeletal animation

2. The existing technical solutions cannot well reflect the roles of personnel at different levels in the animation production process, so it is impossible to achieve the best work combination and obtain the greatest benefits

3. In the current skeletal animation technology scheme, after the drawing of the modeling graphics is completed, the attachment relationship between the two is realized by manually drawing the bones. It is only an additional adjustment tool based on hand-painting, which basically belongs to traditional hand-painting. In the category of animation, the automatic generation of motion process animation cannot be realized, and it cannot meet the actual needs of intelligence and automation in the current computer two-dimensional animation production process, nor does it meet the current industrial requirements for high-efficiency and high-quality two-dimensional animation production. The future development of animation is unfavorable
