Brief description of the drawings
Fig. 1 is the flow chart of the implementation method for 720 degree of panorama players for possessing view angle switch function.
Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
It is shown in Figure 1, the realization side of 720 degree of panorama players for possessing view angle switch function in the embodiment of the present invention
Method, specifically include following steps：
S1：The deployment security sandbox file in streaming server (Adobe Media Server)：In configuration file compressed package
The middle configuration for determining connection streaming server；The operating right of the video flowing of configuration file compressed package is arranged to open, with after an action of the bowels
Phase operates to video flowing.
S1 idiographic flow is：
S101：The configuration file compressed package (main.far) in streaming server is decompressed, obtains master configuration file
(main.asc)。
S102：Master configuration file is opened by text, the configuration of connection streaming server is determined in master configuration file, is opened
In master configuration file after the operating right of video flowing, master configuration file is preserved.
In S102 " configuration of connection streaming server is determined in master configuration file, opens video flowing in master configuration file
The specific implementation program of operating right " is：Application.onConnet () method is found, opens p_
Client.audioSampleAccess="/"；And p_client.videoSampleAccess="/" annotation.
S103：Master configuration file after preservation is compressed, obtains new configuration file compressed package；Generate new configuration
The file name of compressing file bag, after original configuration file compressed package to be replaced with to new configuration file compressed package, restart stream
Server.
It is by the idiographic flow that the master configuration file after preservation is compressed in S103：Looked into instrument (tools) file
Packing (far) instrument is looked for, strapping tool is run in dos systems master configuration file is compressed；Generate new configuration file
The idiographic flow of the file name of compressed package is：Input far-package-archive main-files mian.asc
Applicatio.XML。

Program is View.camera.lens.far=2000 (i.e. distance is 2000 pixels).The purpose of the step is：By tradition
2D play mode show and be set as 3D play mode, the normal play of convenient 720 ° of video flowings below.
S3：3D visual angles ball is created in panorama player, the textures material in the ball of 3D visual angles is arranged to two-sided considerable
See and (inner side and outer side can be watched simultaneously), the texture of textures material is created as picture texture.The purpose of the step is：Wound
3D balls are built, exactly in order to simulate the 3D worlds, top dome is sky, and ball bottom is the earth.
S4：3D visual angles ball in 3D cameras in S2 and S3 is bound and (3D cameras are placed in the ball of 3D visual angles
Portion)；Mouse event is monitored, enables a user to operate mouse to watch the texture of 3D visual angles ball.
Camera (people) is set among ball by S4, that is, is simulated and come 3D worlds middle, such user's can
It is normal to go to experience the material that the simulation 3D worlds provide).
S5：According to the configuration that streaming server is connected in S1, panorama player is attached with streaming server；Caching is set
After time, DST PLAYER (Video) is created to play video flowing, Video is not loaded onto 3D scenes.The purpose of the step
It is：The Streaming Media on streaming server is obtained, and simulates the source material for coming the 3D worlds.
S6：Panorama player obtains the video flowing that streaming server returns, and periodically intercepts the picture (cycle in video flowing
Time is less than 40 milliseconds, is 30 milliseconds in the present embodiment).
The idiographic flow of picture intercepted in S6 in video flowing is：(used by BitmapeData Draw methods
Vector renderer draws source on bitmap images and shows object when Flash is run, and source is exactly that target shows object) come
Obtain the stream picture of bitmapedata forms (bitmap image format).The purpose of the flow is：Because the 3D generation simulated in S4
Boundary's material setting is bitmap, so the convenient tiling of the bitmap inside the video flowing parsed in S6 is into the 3D worlds of simulation.
S7：By the picture refreshing intercepted in S6 to 3D visual angles ball so that the picture on the ball of 3D visual angles regards for newest 720 °
Frequency stream picture, watching live user only needs to operate can rotary viewing visual angle by right mouse button, the 3D of viewing simulation in real time
The newest scene in the world.
