【摘要】：基于WebGL的在线3D建模系统,是一个在线网页版3D建模平台,是一个旨在帮助用户在短时间内完成3D建模作品的在线设计工具,而基于浏览器的3D建模系统降低了普通用户使用3D建模所需的技术要求,帮助非专业技术人员参与3D设计。系统采用WebGL技术对3D模型进行显卡加速渲染,且无需在客户端安装庞大的建模软件,用户只需打开网页进入系统,即可使用简单快捷的建模工具,真正做到大众化的特点。同时,对于完成的模型及场景还可以进行导出导入,用户之间可以对彼此的模型进行交换与修改,真正做到可用性与实用性。本文通过对基于WebGL的3D建模关键技术的研究,介绍了3D场景设计、模型渲染与操作、场景数据处理等方法,并提出模型文件预加载、文件压缩传输等优化系统性能的方法。在有限带宽的条件下将3D数据在浏览器端实时渲染,确保用户在建模过程中数据的导入导出的正确性,充分提高系统的交互性与可用性。
[Abstract]:The online 3D modeling system based on WebGL is an online web version 3D modeling platform. It is an online design tool designed to help users complete 3D modeling works in a short time. The browser-based 3D modeling system reduces the technical requirements required by ordinary users to use 3D modeling and helps non-professional technicians to participate in 3D design. The system uses WebGL technology to speed up rendering 3D model, and does not need to install a huge modeling software in the client, users only need to open the web page to enter the system, can use a simple and fast modeling tools to achieve the characteristics of popularity. At the same time, the completed models and scenarios can also be exported and imported, users can exchange and modify each other's models, so that the usability and practicability can be achieved. Based on the research of the key techniques of 3D modeling based on WebGL, this paper introduces the methods of 3D scene design, model rendering and operation, scene data processing and so on, and puts forward some methods to optimize the system performance, such as pre-loading of model files and file compression and transmission. Under the condition of limited bandwidth, 3D data is rendered in the browser in real time, which ensures the correctness of the user's data import and export in the process of modeling, and fully improves the interaction and usability of the system.
