Fig. 2 shows a kind of flow chart for Real-time windows target generation method that first embodiment of the invention is provided, and refers to figure
2, methods described includes：
Step S310, creates a single document engineering based on MFC.
Wherein, the MFC is the abbreviation of Microsoft Foundation class libraries, is the c++ class libraries that Microsoft realizes, predominant package
Most windows api functions.MFC in addition to being a class libraries, or a framework there is provided it is powerful based on
Windows application framework, and abundant window and incident management function.
Step S320, the zsVegaView classes that a Vega is provided are imported in the single document engineering, described
ZsVegaView classes are corresponding with the Virtual Marine cabin model pre-established.
Because Vega provides the application programming interfaces with C language, provided for software designer soft to greatest extent
Part is controlled and flexibility, therefore designer is usually entered using standard Win32 Console programs (Console Application)
Row programming.
Wherein, the zsVegaView classes are the derived class of MFC application program CView classes, the zsVegaView classes
Basic function is to open a thread, and Vega colorings are put into the View windows based on MFC application programs.
Step S330, is invoked at the zsVegaView in MFC application program CView classes::RunVega () function opens line
Journey.
Step S340, calls vgInitWinSys () function, vgDefineSys () function and vgConfigSys () function

As a kind of specific embodiment, referring to Fig. 3, step S340 can include：
Step S341, calls vgInitWinSys () function, and by creating, shared memory field and signaling zone are to Vega systems
System is initialized.
Step S342, calls vgDefineSys () function, by call definition file, reads described define in file
Data and the database for loading correlation, create the class needed and event is defined to Vega systems.
Step S343, calls vgConfigSys () function to configure the example of the class of the needs.
Step S350, calls Vega primitive recursive functions, obtains current in each circulation of the Vega primitive recursive functions
The ship what comes into a driver's figure at moment, ship what comes into a driver's figure and multiple nodes pair in the model of the Virtual Marine cabin at the current time
Should.
Wherein, Virtual Marine cabin model can be the three-dimensional in the Virtual Marine cabin set up by Creator instruments
Model, Virtual Marine cabin model can be stored using OpenFLight forms and with the structure of stratification,

The directed acyclic graph being made up of multiple nodes in the model of the Virtual Marine cabin.
The input information, can be the click information of mouse, the key information of keyboard or the corresponding gesture letter of touch-screen
Breath etc..
In addition, can no longer carry out the acquisition of follow-up Real-time windows target figure if described exit if flag bit is 1, directly exit
The ship Scene wandering system.
Wherein, the vgFrame () function includes pfCull () function and pfDraw () function, described to call
The ship scene graph at current time is rejected and drawn described in vgFrame () function pair, obtains the ship what comes into a driver's at current time
Figure, can include：

The node outside visual line of sight answered, and by each node in the ship scene graph at the remaining current time and its corresponding
Render instruction associated storage；PfDraw () function is called, the related data difference wash with watercolours in the render instruction and database
Contaminate corresponding node in the ship scene graph at the remaining current time, and the ship at the current time after rendering
Scape figure is plotted on display device as the ship what comes into a driver's figure at the current time.
Wherein, reject in the ship scene graph at the current time in the corresponding visual line of sight of the current view information
During outer node, each node of the ship scene graph at the current time can be traveled through, by judging the current time
Whether the node in ship scene graph is in observation body (being used for the imaginary solid for representing the corresponding visual line of sight of view information)
Portion, to determine which node is visible for current view point, rejects and adjusts sightless node in current view point visual line of sight
.In addition, each node in the ship scene graph at the remaining current time and its corresponding render instruction are associated
During storage, it can be stored in the form of a list in internal memory, and the list is only effective in this circulation, is performing next time
It is eliminated during circulation.It is understood that the mode of storage does not constitute the limitation to the embodiment of the present invention.
Related data in the database can include corresponding with each node in the model of the Virtual Marine cabin
The data such as polygon, texture, color, the effect of shadow of storage.
