A real-time motion simulation method for collision between hair and objects

Abstract

The invention discloses a real-time hair object collision motion simulation method. Based on a small amount of pre-calculated training data, the method generates an adaptive simplified model for a virtual hairstyle, which is used for real-time selection and interpolation, and performs collision correction, thereby realizing real-time high-quality hair Object collision motion simulation. The method mainly includes the following steps: 1) Simplified model precomputation: Based on the pre-calculated simulation data, select representative hair and generate a simplified model; 2) Real-time motion simulation and interpolation: cluster the representative hair in real-time simulation, select the simplified 3) Collision correction: Perform collision detection and apply the correction force to the representative hair to correct the collision situation. The present invention proposes a real-time hair object collision simulation method for the first time, which can achieve similar effects to offline simulation while greatly reducing calculation time, and can realize high-quality collision motion simulation for complex character hairstyles, which is superior to existing methods and has strong versatility , Easy to use and so on.

Description

technical field [0001] The invention relates to the field of computer motion simulation, in particular to a method for real-time motion simulation of virtual character hair. Background technique [0002] The relevant research background of the present invention is briefly described as follows: [0003] Realistic virtual hair motion modeling and simulation has very important applications in computer animation, virtual reality and other fields. From the early work that did not consider the interaction between hair strands at all (Rosenblum, R.E., Carlson, W.E., and Tripp, E.1991. Simulating the structure and dynamics of human hair: modeling, rendering and animation. The Journal of Visualization and Computer Animation2,4,141–148.) (Anjyo, K.-I., Usami, Y., and Kurihara, T.1992. A simple method for extracting the natural beauty of hair. In ACM SIGGRAPH Computer Graphics, vol.26, ACM, 111–120.), hair motion simulation has been a hot research topic. [0004] The most common app...

All such heuristic models are essentially a compromise between effectiveness and efficiency, and there is no guarantee that they can achieve effects similar to high-precision simulation while greatly reducing computational overhead, so their quality will usually be greatly affected

[0007] Recently, a real-time hair motion simulation method based on motion simplified model (Chai, M., Zheng, C., and Zhou, K. 2014. A Reduced Model for Interactive Hairs. ACM Transactions on Graphics, 2014, 33 (4)) can do to real-time hair motion simulation, but cannot accurately handle fine collisions with objects
