具有沉浸感的毛笔书写行为实时仿真
Real-Time and Immersive Simulation of Chinese Calligraphy Brush

提出一种毛笔书写行为的实时仿真技术.在毛笔的几何外形方面，采用了骨骼蒙皮的建模方式，并提出一种骨骼旋转参数的快速算法，从而实现了笔头在运动过程中的弯曲和扭转两种变形效果；在水墨效果方面，采用了基于粒子系统的墨水扩散模型，能够灵活地控制墨迹在纸面上的浸染效果.基于上述技术，使用头戴显示器和力反馈设备，实现了一个毛笔书写仿真系统，具有很好的实时性和沉浸感.
A real-time simulation technique for writing behavior of Chinese calligraphy brush was presented. In terms of the geometric shape of brush, the modeling method of the skin-skeleton was adopted, and a fast algorithm for the rotation parameters of the bone was proposed, which realized the two deformation effects of the pen head during the movement process; in terms of the ink effect, the ink diffusion model based on the particle system was adopted, and it could flexibly control the effect of ink on the paper surface. Based on the above techniques, using a head-mounted display and a force feedback device, a brush writing simulation system was implemented. Results show the better real-time and immersive feeling
