摘　　要：船闸作为水利枢纽中重要的组成部分,其复杂的建筑构成决定了船闸处场景展示需要更真实的渲染效果。对此,利用Web图形库(Web graphics library,WebGL)支持浏览器端3D硬件加速渲染的优势,使用Web3D图形库Babylon.js构建了广东北江航道的枢纽船闸处的场景。根据船闸工作过程,提出了船闸动态交互方法,实现了船舶通过船闸的沉浸式动态展示。开发了船闸处的视点、天气、模型的控制以及船舶模拟行驶、水上水下一体化的辅助功能,以多角度多层次展现船闸环境。研究表明,构建的Web三维场景能够全方位展示船闸枢纽,同时具有一定的应用性,能够对船闸处的规划设计提供思路与参考。As an important part of the hydrojunction,the complex architectural composition of the ship lock determines that the scene display of the ship lock requires a more realistic rendering effect.In this regard,we take advantage of Web graphics library(WebGL)to support browser-side 3D hardwareaccelerated rendering,and use the Web3D graphics library Babylon.js to construct the scene at the ship lock of the Beijiang Channel in Guangdong.According to the working process of the ship lock,a dynamic simulation method of the ship lock is proposed,which realizes the immersive dynamic display of the ship passing through the ship lock.The control of viewpoints,weather,and models at the ship locks,as well as auxiliary functions for ship simulation driving and integration of water and underwater,have been developed,which can display the environment of the ship lock at multiple angles and levels.Provide construction methods for 3D scene simulation of the ship lock,and provide ideas and references for planning and design of the ship lock.
