Rapid generation method of role hair style in three-dimensional animation

Abstract

The invention provides a rapid generation method of a role hair style in a three-dimensional animation. The method comprises the steps that the outline of a strand of hair in a non-braid zone is established, any curve Y on the outline is converted into a single piece of hair S in a hair manufacturing tool, and a set S' of single pieces of hair corresponding to all strands of hair is obtained; in the same way, a set W' of single pieces of hair corresponding to all strands of hair in a braid zone is acquired; a single piece of hair Z is established in the hair manufacturing tool along the center line of a braid, and skeleton nodes are established along a curve Z and provided with binding weights; after role movement of a current frame, dynamic resolving is carried out on the single piece of hair Z, then dynamic resolving is carried out on the set S' and the set W' to obtain a curve set X1 and a curve set X2 respectively, multiple hair curves are generated with all curves in the curve set X1 and the curve set X2 serving as path curves in an L system, and then the role hair style of the current frame is obtained. The hair style dynamic system adopted in the method is high in resolving speed, and the generated braid does not get loose easily.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional animation, and in particular relates to a method for rapidly generating character hairstyles in three-dimensional animation. 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 software (such as 3ds Max, Maya or Houdini) to build a virtual world in the computer; then, add scenes and 3D models such as 3D cartoon characters to the virtual 3D world ; 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 anim...

AI Technical Summary

Problems solved by technology

[0010] A) Using the L system can provide flexible control of the hair trend, and can quickly and conveniently create various hairstyle effects, but does not support dynamic calculation

[0011] B) The hair making tool provides a variety of control over the hair shape, such as combing strands into braids, the rendering effect is better, and it also supports dynamic calculation, but it is difficult to shape the desired hairstyle, and the hairstyle It is also difficult to maintain, for example, braids are easy to diverge under dynamic simulation
