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.
See also Fig. 1; The three-dimensional picture engine that is used for Object Management group of the present invention; Comprise and add object unit 10, render objects unit 11, deletion object unit 12, upgating object unit 13 and object queue unit 14; Said interpolation object unit 10 is used for adding object to the object queue unit; Said render objects unit 11 is used for render objects to reach the three-dimensional motion effect, and said deletion object unit 12 is used for no longer object 14 deletions from the object queue unit of needs, and said upgating object unit 13 is used for the attribute of upgating object queue unit 14 each object.
The present invention utilizes the three-dimensional picture engine that three dimensional object is managed, and reduces the three-dimensional graphic object complexity of developing of embedded software, and improves the development efficiency of embedded software and the ease for maintenance that strengthens embedded software.
In one embodiment, said interpolation object unit is added object through internal memory, picture address or video handle path.Said graphics engine provides a handle for each object; Calling program is through handle identification and call three dimensional object; Said graphics engine couples together object queue of formation to the object that will manage with the mode of chained list, controls these objects through timer and carries out playing up for 60 times to reach the three-dimensional motion effect according to the attribute per second of each object.
In one embodiment, when said deletion object unit is deleted from the object queue unit at the object that will no longer need, also discharge the shared video memory space of this object simultaneously.
In addition, when the special efficacy object is handled, be achieved in that
Be to realize the special efficacy requirement of digital entertainment equipment, said graphics engine also provides independently the special effect processing function to realize complicated special efficacy needs.In OpenGL; Sometimes need draw the picture material of appointment to subject surface; Said picture material just is called texture; Said texture must be placed in the surface space (the video memory space is called for short in Embedded video memory space below) and the texture numbering of binding an OpenGL just may be plotted in the surface of object.The texture apex coordinate is the mapping that texture arrives subject surface, is plotted to the surface of object through texture apex coordinate control texture.Adopt object to bind more textures summit, and in playing up thread, go control to play up thread each texture vertex information in service, realize the special efficacy that three dimensional object is more complicated according to content in the video memory space of object.
Four summits that common object is only bound rectangular area as shown in Figure 2 are the texture summit; Said special effect processing function active said object cutting is become the summit and the face of prescribed level as shown in Figure 3 and the binding of optimization objects and summit computational algorithm.For example, want to realize special efficacys such as Aladdin and His Lamp, need refinement texture summit, the summit control function of the mode of motion of design Aladdin can reach the drafting of special efficacy process.
The number of vertex of object is many more, and it is just big more that hardware is played up complexity, and frame frequency is played up in influence.
In playing up thread, add calculating and method for drafting to every kind of special efficacy of each object, go to control the motion on these summits, playing up of per second tens frames can produce a lot of three-dimensional special efficacys attractive in appearance of more extremely dazzling in the thread through playing up like this.
If the special effect processing that do not unbind function, the special efficacy object is just the same with the operation of common object.
