基于OSG的三维GIS功能的封装技术研究与实现

Research and Implementation of 3D GIS Function Packaging Technology Based on OSG

OpenSceneGraph(以下简称OSG)使用OpenGL技术开发,是以C++作为开发语言的应用程序接口(API),它让开发者能快速、便捷地交互式图形程序。在三维GIS领域,使用OSG作为底层渲染是不二之选。本技术研究拟从如何将底层基于OSG使用C++开发的功能进行封装(ActiveX技术),从而对C#和JavaScript等二次开发语言调用等方面进行研究,实现定制化开发和功能扩展,实现应用项目想要的功能。

OpenSceneGraph(OSG) adopting OpenGL technology uses C++ as the development language for application programming interface(API). It is a fast and convenient interactive graphics program for developers. In 3D GIS,the use of OSG for the underlying rendering is the best choice. This paper discusses a method for packaging the underlying OSG technology by using using C++ as the development language(ActiveX),thus C# and JavaScript development language calls can be implemented to realize customized development and expansion of functions,and achieve the desired function of project application.
