| 摘 要： | 随着Web 3 D技术和大数据的发展,三维模型在Web端的传输和可视化成为迫切需求.面对Web端大数据实时传输这一挑战,超图三维团队在多年技术积累下,对倾斜摄影模型、3 DMax建模、BIM、矢量、三维管线以及单体化、实例化等内容进行整合,最终形成了海量三维数据规范——S3 M(SuperMap 3 D Model).通过这种高效、易扩展、可协作的数据规范,解决了三维数据传输和解析延迟问题,并通过WebGL支持硬件加速的可视化渲染技术,兼容多终端(移动、浏览器、桌面)的跨平台特性,最大限度地满足了用户需求.

| Abstract: | With the development of Web 3D technology and big data, there is huge demand on the delivery and visualization of 3D models through Web. To deal with the challenge of real-time transmission for 3D models, SuperMap 3D team integrates diverse as-pects including oblique photogrammetry, 3DMax Model, BIM, vector, and 3D pipeline as well as contents of singularity and instance et al. with technological accumulation over years to create a 3D format standard. The format is called SuperMap 3D Model (S3M) and it supports the delivery and visualization of massive 3D data. The format is efficient, easy to extension, co-operated, and helps to solve the latency during the delivery and parser of large 3D modes on Web. It also supports WebGL rendering based on hardware ac-celeration and is compatible for multi-platforms including mobile devices, Web browsers, and GIS desktop software, satisfying as many as practical needs as possible for all and potential users. |
