基于WebGL的牙颌模型交互控制与实现

目前三维模型的可视化主要是基于OpenGL和DirectX实现的,但传统工具最大缺点是存在跨平台的兼容问题。随着互联网技术的发展,浏览器平台的兼容性越来越好。针对上述问题,提出一种基于WebGL的牙颌模型交互控制方法。该方法具有良好的跨平台性,解决了传统工具对插件或第三方组件的依赖,可直接在浏览器上实现牙颌模型的平移、旋转和缩放功能;利用四元数实现旋转算法,大大减小了存储空间,降低了计算过程中的复杂性;同时避免旋转中常见的万向节锁问题。最后通过实验证明,该方法可以展现给人一种清晰、直观、流畅的鼠标控制效果。

Interaction Control and Implementation of Dental Model Based on WebGL

At present, visualization of 3D model mainly based on OpenGL and DirectX, the biggest drawback of traditional tools is the existence of cross-platform compatibility issues. With the development of Internet technology, the compatibility of the browser platform is getting better and better, according to the above problem, this paper proposes a interactive control method of dental model based on WebGL. The method has a good cross-platform, theSsolutionsSofStraditional toolsSareSdepended on plug-in or third-party components, on the browser can make dental model to complete the translation, rotation and scaling function, using quaternion to achieve rotation algorithm, savingSspace, reducingScomplexity of the calculation process, while avoiding gimbal lock in the rotation. Finally, through the experiment proved that the method can show a clear, intuitive, smooth mouse control effect.
