The present invention utilizes message management engine that playing up of three dimensional object in three-dimensional picture engine moved and managed the opportunity of playing up, and has further optimized the work efficiency of three-dimensional picture engine, has reduced the complexity of the three-dimensional graphic object exploitation of embedded software.
In one embodiment, described motion message management module comprises mobile messaging unit, convergent-divergent message elements, rotation message elements, desalination message elements, inverted image message elements and the transforming message unit, visual angle of respectively object being played up action control.
In one embodiment, described message call administration module comprise for start calling of playing up start module and for close play up call end module.
In one embodiment, in transforming message unit, described visual angle, include eye position, alignment point and direction vector data.
In one embodiment, described in call and start module and call to finish module and also comprise enabling of sending for control message, only start module and start and call and finish the message that module sends between starting and just come into force calling.
In one embodiment, call and start when module starts also to comprise the action that locks, while calling the startup of end module, also comprise release action.
The attribute of object mainly comprises the sign whether three-dimensional coordinate of object present position, the three-dimensional size of scaling, the degree of desalination demonstration, three-dimensional anglec of rotation size, the height of inverted image and the transparency of inverted image, object show.
The management system of three-dimensional graphic object of the present invention, comprises above-mentioned three-dimensional picture engine and above-mentioned message management engine, and described message management engine carries out message management to described three-dimensional picture engine.
Below, with a preferred embodiment, be elaborated:
1. object message management
Each object comprises a message queue, comprising movable informations (also referred to as motion message) such as movement, convergent-divergent, rotation, desalination, inverted image and visual angle conversions, and by calling beginning (EVGEBegin) and finishing (EVGEEnd) function and control the serial of above-mentioned action or walk abreast.
The instruction sending according to calling program by message mechanism control object changes action and plays up mode.When object message queue is sky, when receiving message, carries out object at once.Different start and finish function and send to the message of single object serial to carry out, different time sections sends to the message of different objects can executed in parallel, but does not guarantee that the message energy serial of different objects carries out.
Message in described graphics engine comprises object message and global message, the message queue of an object of each object maintenance, and global message is safeguarded by a message queue.In described graphics engine, have one to play up thread and move always, play up thread according to the content of the attribute rendering objects of object the Frame Buffer to display frame, allow message carry out in playing up thread simultaneously.
Object message bag is that the height of alpha value the 3 d scale of the 3 d scale of the three-dimensional coordinate of the present position in object properties, convergent-divergent, rotation, desalination, inverted image and transparency and each are played up the variable quantity of object properties in the cycle and be packaged together and form.The message of object has comprised the motion message such as movement (EVGEMove), convergent-divergent (EVGEScale), rotation (EVGERotate), desalination (EVGEFade), inverted image (EVGEReflect), demonstration hiding (EVGEShow), and the state attribute value that the parameter of object function message will be reached by object handle, message and the frame number of playing up needing form.
Global message is mainly visual angle transforming message (EVGELookAt), and message comprises eye position, alignment point, direction vector.Global message bag is that the variable quantity (being called for short every frame increment) that these attributes and each are played up to attribute in the cycle is packaged together and forms.
Start and finish function and be used for enabling of control message transmission, the message only sending between starting and finishing just comes into force, and the while locks when beginning, and during end, release is to guarantee the safety of Multi-thread control.
In described graphics engine, also comprise that the caller that call back function offers in calling program is used, message bag calls the call back function of calling program appointment after carrying out and finishing.Described call back function is the function that described graphics engine offers user's registration function and parameter, and user can utilize this function specified function name and parameter to described graphics engine, and described graphics engine utilizes the parameter of appointment to carry out the function of appointment.
2. the interpolation of message
As Fig. 1 shows, after calling beginning function, start to add message.If the motion message of adding is global message, described motion message is directly joined to the end (if queue is for empty, adding into head of the queue) of global message queue.If the message of adding is object message, described motion message is joined to the end (if queue is for empty, adding into head of the queue) of the message queue of this object, and call end function.
In order to strengthen the stability of described graphics engine, described graphics engine has been stipulated the message number of each message queue maximum, if the message number in queue surpasses restriction, abandons message to be added.
3. message is carried out
As Fig. 2 shows, play up the maintenance of queue and controlled by timer, after described graphics engine starts, first start timer and to playing up function, send out event 60 times p.s., each event is carried out something, is lockable release if play up lock.Execution is played up in the process of function, can go traversal to play up each object in queue, and being confirmed whether will be according to the state of information updating object.As long as have message in the message queue of object, carry out the head of the queue message of this message queue, delete this message after executing this message.The visual angle transforming message of the overall situation is also the same.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes instructions of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
