Embodiment
By specifying technology contents of the present invention, structural attitude, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
Message management engine of the present invention; Be used for the three-dimensional picture engine is carried out message management; Said three-dimensional picture engine comprises interpolation object unit, render objects unit, deletion object unit, upgating object unit and object queue unit; Said interpolation object unit is used for adding object to the object queue unit; Said render objects unit is used for render objects reaching the three-dimensional motion effect, and said deletion object unit is used for the object of needs is no longer deleted from the object queue unit, and said upgating object unit is used for the attribute of each object of upgating object queue unit; Said message management engine comprises the message call administration module on the motion message management module of playing up action that is used to control the render objects unit and the opportunity of playing up that is used to control the render objects unit.
The present invention utilizes the message management engine that playing up of three dimensional object in the 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 three-dimensional graphic object complexity of developing of embedded software.
In one embodiment, said 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, said message call administration module comprise be used to start play up call the beginning module be used to close play up call the end module.
In one embodiment, include eye position, alignment point and direction vector data in the transforming message unit, said visual angle.
In one embodiment, the said beginning module of calling finishes module and also comprises enabling of being used for that control messages sends with calling, and only starts and calls and finish the message that module sends between starting and just come into force calling the beginning module.
In one embodiment, also comprise the action that locks when calling the startup of beginning module, call and finish also to comprise when module starts the release action.
The attribute of object mainly comprises size, the degree that desalination shows, three-dimensional anglec of rotation size, the height of inverted image and the transparency of inverted image of the three-dimensional coordinate of object present position, three-dimensional scaling, the sign whether object shows.
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, be elaborated with a preferred embodiment:
1. object message management
Each object comprises a message queue; Comprising move, movable informations (being also referred to as motion message) such as convergent-divergent, rotation, desalination, inverted image and visual angle conversion, and through calling beginning (EVGEBegin) and finishing (EVGEEnd) function and control the serial of above-mentioned action and perhaps walk abreast.
The instruction of sending according to calling program through the message mechanism controlling object changes action and plays up mode.When the object message formation is sky, when receiving message, carries out object at once.Different beginnings and finish the message that function sends to single object and can serial carry out, different time sections send to the message of different objects can executed in parallel, but does not guarantee that the message of different objects can carry out in serial.
Message in the said graphics engine comprises object message and global message, and each object is safeguarded the message queue of an object, and global message is safeguarded by a message queue.There is one to play up thread and move always in the said graphics engine, plays up thread, let message in playing up thread, carry out simultaneously according to the content of the attribute render objects of object Frame Buffer to display frame.
The object message bag is that height and transparency and each of alpha value, inverted image the 3 d scale of the 3 d scale of the three-dimensional coordinate of the present position in the object properties, convergent-divergent, rotation, desalination played up in the cycle variable quantity of object properties and be packaged together and form.The message of object comprised and moves (EVGEMove), convergent-divergent (EVGEScale), rotation (EVGERotate), desalination (EVGEFade), inverted image (EVGEReflect), shows and hide (EVGEShow) the motion message of etc.ing, the state attribute value that the parameter of object function message will be reached by object handle, message and need the frame number of playing up form.
Global message mainly is visual angle transforming message (EVGELookAt), comprises eye position, alignment point, direction vector in the message.The global message bag is to be packaged together the variable quantity (be called for short, every frame increment) that these attributes and each are played up attribute in the cycle and form.
Beginning and end function are used for enabling of control messages transmission, and the message of only between beginning and end, sending just comes into force, and the while locks when beginning, the safety of release to guarantee that multithreading is controlled during end.
Comprise also in the said graphics engine that the caller that call back function offers in the calling program uses, call the call back function of calling program appointment after the message bag is carried out and finished.Said call back function is the function that said graphics engine offers user's registration function and parameter, and the user can utilize this function specified function name and parameter to give said graphics engine, and said graphics engine utilizes designated parameters to carry out the function of appointment.
2. the interpolation of message
Show like Fig. 1, call after the beginning function, begin to add message.If the motion message of adding is global message, then said motion message is directly joined the end (if formation is then added into head of the queue for empty) of global message formation.If the message of adding is object message, then said motion message is joined the end (if formation is then added into head of the queue for empty) of the message queue of this object, and call the end function.
In order to strengthen the stability of said graphics engine, said graphics engine has been stipulated the maximum message number of each message queue, if the message number in the formation surpasses restriction, then abandons message to be added.
3. message is carried out
Show like Fig. 2, play up the maintenance of formation and control that after said graphics engine starts, at first start timer and send out incident 60 times to playing up function p.s., each incident is carried out something, is lockable then release if play up lock by timer.Execution is played up in the process of function, can remove to travel through each object of playing up in the formation, and whether confirm will be according to the state of information updating object.As long as in the message queue of object message is arranged, then 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 also is the same.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes instructions of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
