It should be noted that, OpenSceneGraph is a high performance three-dimensional image rendering engine of increasing income, and the LGPL agreement (OSGPL) based on amendment is freely issued, and is widely used in the fields such as visual simulation, virtual reality, scientific visualization and modeling.To become the OpenGL of industrial standard for underlying platform, use portable ANSI C++ to write and form.On the basis to encapsulation, set up an OO framework, make programmer can break away from numerous and diverse modeling of bottom, be more convenient for Develop Application System and management.Possess cross-platform characteristic, can run on each type operating systems such as Windows, Mac OS X, UNIX/Linux, Solaris, FreeBSD and AIX.OpenSceneGraph additionally provides many useful kits so that more fast program development in addition.OpenSceneGraph is just based on scene graph technology the most prevailing in the world, and oneself has the exploitation carrying out graphic package more than 1000 developers based on OpenSceneGraPh now.OpenSceneGraph is with its powerful function, and perfect development mode and development transplantability are subject to by force the general favorable comment of industry.OpenSceneGranh graphics engine is adopted to overcome traditional shortcoming that OpenGL and the Direet3D construction cycle is long, difficulty is large, solve commercial engine cost of development such as using OpenGVS, Vega too high, be unfavorable for the problem of product promotion, more meaningful the angle of practicality.Had much successful application based on OSG at present, as Delta3D, 3DVRI, Remo3D, osgPlanet, Virtual Terrain system, vehicles analogue system etc., effect is not second to business vision rendering software.If want independent development vision rendering software, be that best architecture is selected.OpenSceneGraph is open source code, and its user's license method is the wide general public licence of GNU (GNU Lesser GeneralPublic License, LGPL) revised.OpenSceneGraph adopts the secret sharing of form of increasing income to possess many advantages:
1, fast Development: OpenSceneGraph scene graph kernel encapsulates most OpenGL physical layer interface, and supports up-to-date extended attribute at any time.Center of gravity can be placed in the essentiality content of three-dimensional program development and the mutual method of various scenario objects by Develop Application System person, and no longer too much pays close attention to bottom code.
2, high-quality: OpenSceneGraph is carried out checking, test and improving by many members of OSG community repeatedly.Participate in core code exploitation directly and the personnel that contribute to some extent have exceeded 200 people.
The core code of 3, high-performance: OpenSceneGraph supports several scenes tailoring technique, level of detail node, rendering state sequence, vertical array, display list, VBO, PBO, FBO, OpenGL shading language etc.; And text importing, particIe system, shadowing systems, the Specially Effect Simulations such as rain, snow, flame, smog, the dynamic dispatching of scene, multithreading such as to play up at the various mechanism.Improve program quality: write high-quality program, developer needs extremely to understand oneself kit used.If this kit not open source code, the exploitation information relevant to it is just closed, and user can only obtain exploitation information by the document of developer and customer support.Open source code makes programmer can check and debug the source code of kit used, fully understands code internal information.
4, extendability: based on the expansion thought of scene graph, OpenSceneGraph provides powerful expandability, comprise various types of extended node (NodeKits, node tool box), expansion renderer property, expansion readjustment, expansion alternative events processor etc., the program development for user provides tenability flexibly.
In sum, the disposal route of the three-dimensional geographic information of first embodiment of the invention, solve the problem that three-dimensional geographic information disposal route in prior art causes three-dimensional geographic information picture display rate slow, and then reach the effect of the display speed promoting three-dimensional geographic information image.GD-Earth three-dimensional geographic information platform based on the disposal route of the three-dimensional geographic information of first embodiment of the invention supports the terrain data of TB level, multithreading render engine and model data dynamically add offload scheduling, the fluency that the program that ensure that is run, decreases the stand-by period of the network user simultaneously.
The disposal route of the three-dimensional geographic information that the embodiment of the present invention provides, by detecting whether there is three-dimensional geographic information load request, if three-dimensional geographic information load request detected, has loaded three-dimensional geographic information; In the process loading three-dimensional geographic information, the 3-D view that drawing three-dimensional geography information is corresponding, and output 3-D view, solve the problem that three-dimensional geographic information disposal route in prior art causes three-dimensional geographic information picture display rate slow, and then reach the effect of the display speed promoting three-dimensional geographic information image.
Fig. 3 is the process flow diagram of the disposal route of three-dimensional geographic information according to a second embodiment of the present invention.Fig. 3 can as a kind of preferred implementation embodiment illustrated in fig. 1.As shown in Figure 3, the method comprises following step S301 to step S307:
Step S301, detects whether there is three-dimensional geographic information load request.
This step, with above-mentioned steps S101, does not repeat them here.
Step S302, if three-dimensional geographic information load request detected, has then loaded three-dimensional geographic information.
This step, with above-mentioned steps S102, does not repeat them here.
