| 摘 要： | 提出了一套虚拟投篮系统设计架构，建立一个虚拟现实场景，其中包括球场、运动员和篮球，并为篮球添加运动和弹性形变两种物理模型. 文中设计的系统模拟了篮球从出手后到落地静止的整个运动过程，描述了篮球出手后在空中的飞行轨迹以及篮球与篮板、地板碰撞时发生的弹性形变. 实验结果表明，文中所采用的算法模拟投篮过程，效果逼真，能满足系统实时性的要求，在具体应用中可以提高运动员的训练效率.

| Abstract: | A set of construction of virtual basketball shooting system is designed. A virtual reality scene is established including a basketball court, athletes and a basketball. It provides models for the movement and elastic deformation of the basketball. The entire process of the basketball movement, from shooting to stopping, is simulated by describing the ball’s moving traces, and the elastic deformation in its collision with ground. Experimental results show that the proposed algorithm is efficient in simulating the virtual shooting process and is applicable to improve the athletes training efficiency. |
