Problems solved by technology

However, in 3D software, an independent weight system is often generated for each secondary controller, and then these control systems are processed sequentially, and dozens of secondary controllers are often added when debugging expression animations, causing animators to debug animations The deformation of the animation will be very slow, and it is difficult to see the animation effect interactively

Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] A kind of fine animation production method based on the secondary controller of the present invention, comprises the following steps:

[0026] Step 1. Bind the secondary controller set in the animation to the corresponding polygonal surface in the polygonal model, and determine the centroid coordinates of each secondary controller on the respective polygonal surface; wherein, the centroid coordinates are defined as follows : For any polygon in space, let v1, v2, v3...vn denote the coordinates of n vertices of the polygon in the global coordinate system, then the coordinates of any point P in the polygon are expressed as: x1×v1+x2×v2 +x3×v3+…+xn×vn, and x1+x2+x3+…+xn=1, that is, the centroid coordinates of point P on the polygonal surface are: (x1, x2, x3,…, xn);

[0027] The global coordinate system is defined as: any Cartesian coordinate system fi...

Abstract

The invention discloses a fine animation manufacturing method based on secondary controllers. A polygon where all the secondary controllers are located and local coordinates in the polygon are determined; weight data of all the secondary controllers are exported and combined into a single weight system, and thus the speed of debugging an animation can be increased; meanwhile, after the animation is bonded through a skeleton, a displacement rotation transformation matrix M of the secondary controllers relative to the local coordinate system of the secondary controllers is recorded, then the transformation effects of all the secondary controllers are accumulated according to the weight of the secondary controllers to all vertexes on the polygon model, and the fine animation effect controlled by the secondary controllers is achieved. Compared with secondary controllers in existing three-dimensional software, nodes for updating positions of the controller and nodes for the controllers to adjust the positions of the vertexes of the polygon model are established, and otherwise directed annulate images can be formed. Thus, the method further solves the problem that role animation debugging becomes slow after the multiple secondary controllers are added in the existing three-dimensional software.

Description

technical field [0001] The invention relates to the technical field of three-dimensional animation, in particular to a fine animation production method based on a secondary controller. Background technique [0002] Three-dimensional animation technology is a new technology that has emerged with the development of computer software and hardware technology in recent years. It can conveniently and quickly produce three-dimensional animation or film and television special effects shots that meet the needs of directors. [0003] The production principle of 3D animation is generally as follows: First, use 3D animation production tools (such as 3ds Max, Maya or Houdini) to build a virtual world in the computer; then, add scenes and 3D cartoon characters to the virtual 3D world. 3D model; finally, set the animation curve of the model, the trajectory of the virtual camera and other animation parameters, and render the character animation. [0004] Because 3D animation technology has...
