2.5 dimension rope distortion animation generation method

Abstract

The invention discloses a 2.5 dimension rope distortion animation generation method. The method includes the following steps: (1) establishing a rectangular plane coordinate system, defining a dome curve which has periodical changes as an upper end contour in the coordinate system; overturning the upper end contour in symmetry and moving so as to determine a lower end contour, wherein the lower end contour is composed of the upper end contour which overturns symmetrically and the path along which the upper end contour moves; (2) constructing an enclosed region with an outer contour, dividing the region into a plurality of sub-regions, and marking the sub-regions; determining the range of the sub-regions by using the boundary of the region, and constructing four-edge grids in sub-regions; (3) inputting a texture filling of a rope, and determining the filling texture of the sub-regions based on the marks; then determining the mapping relationship between the summits of the four-edge grids within the sub-regions and texture coordinates; (4) and continuously changing the outer contour of the rope, outputting image frames upon rope distortion, and generating animation of the rope distortion. The method has simple principle, is easy to realize, and has excellent animation generation effects.

Description

technical field [0001] The invention relates to a method for generating 2.5-dimensional animation, which belongs to the technical field of computer animation, in particular to a method for generating 2.5-dimensional rope twisting animation. Background technique [0002] In the field of computer animation, animation can be divided into the following three types according to the differences in animation production skills and presentation effects: plane animation, three-dimensional animation and 2.5-dimensional animation. [0003] Chinese patent CN103065348A, titled "A method for automatically generating two-dimensional animation based on a skeletal action library", this type of technology first saves the created bones and skeletal actions in the skeletal animation library; then draws modeling graphics according to the appearance requirements of the modeling; Secondly, the skeletal action is called from the skeletal action library, and the skeletal action is bound to the modeli...

Problems solved by technology

Compared with the traditional 3D human pose modeling method, this technology can effectively support the animator to design and edit the pose of the animation with the method of 2D sketching, but the 3D animation rendering involves a large amount of data calculation and takes a long time
