Specific implementation
Three-dimensional rendering method and three-dimensional rendering device according to the embodiment of the invention are described below with reference to accompanying drawings.Be to be understood that: the embodiments described herein only is illustrative, and should not be interpreted as limiting the scope of the invention.
Illustrated among Fig. 1 playing up that the vertical array/coordinate in the 3D model carries out.Usually, in display device, for scene of game, it all is to play up by the OpenGL mode that general picture is realized, plays up pipeline by OpenGL and enters into the video card buffer memory after playing up again, and then exports.
Yet, as described in the background technology, although in game is used, scene of game has been set up the 3D model, there is the 3D apex coordinate for each summit, but still only presenting the 2D picture in actual displayed, only is that each object in this 2D picture looks to have the different depth of field.In other words, in game is used, do not produce respectively the image that is used for left eye and the image that is used for right eye, do not realize that certainly real 3D shows.
Figure 2 illustrates the image that is used in accordance with the principles of the present invention left eye and the image that is used for right eye.As shown in Figure 2, for a cube that is placed in face of the people, the effect that the effect that left eye looks and right eye look can be along with different and different with respect to this cubical visual angle of human eye.

Next, in conjunction with Fig. 3 three-dimensional rendering method 300 according to the embodiment of the invention is described.
Three-dimensional rendering method 300 according to the embodiment of the invention begins at step S301.
At step S310, obtain the vertex data in the scene.
Use for game, each scene has been carried out the 3D modeling, and correspondingly also generated the vertex data of object in each scene.Therefore, in the present invention, do not consider how to produce the vertex data of object in each scene, and only consider how to utilize the vertex data that has generated to produce for the image of left eye and be used for the image of right eye, thereby realize that real 3D presents.
At this, for scene to be shown, obtain by this scene being carried out the vertex data of object in the described scene that three-dimensional modeling obtains, described vertex data has the coordinate figure (X, Y, Z) in the three dimensions.
At step S320, vertex data is rotated the first predetermined angular to obtain first group of vertex data.At step S330, the second predetermined angulars that the vertex data rotation is different from described the first predetermined angular are to obtain second group of vertex data.This first group of vertex data is the used vertex data of image that is used for left eye for generating.This first group of vertex data is the used vertex data of image that is used for right eye for generating.
Should be appreciated that, have at least one summit in scene, needs rotate the first predetermined angular and the second predetermined angular to the vertex data on each summit respectively.Therefore, step S320 and S330 can carry out simultaneously, also can successively carry out.For example, for each summit, while execution in step S320 and S330, perhaps priority execution in step S320 and S330.Alternatively, first for all summit execution in step S320 again for all summit execution in step S330; Perhaps first for all summit execution in step S330 again for all summit execution in step S320.

Should be appreciated that, can generate respectively the OpenGL that OpenGL for left eye plays up pipeline and be used for right eye and play up pipeline.Alternatively, only exist an OpenGL to play up pipeline, it plays up to present the first image for left eye to described first group of vertex data first, then described second group of vertex data is played up to present the second image for right eye; Perhaps, it plays up to present the second image for right eye to described second group of vertex data first, then described first group of vertex data is played up to present the first image for left eye.
Then, at step S360, utilize the first image and the second image that generate to carry out three-dimensional rendering.Can use existing any 3D to present/display packing, for example, shutter 3D Display Technique and polarization type 3D Display Technique utilize the first image and the second image that generate to carry out three-dimensional rendering.The present invention is not presented/restriction of display packing by concrete 3D.
At last, the three-dimensional rendering method according to the embodiment of the invention finishes at step S399.

Can be with this vertex data in the scene that obtains with first apex coordinate that act on left eye, at this moment, this vertex data in the scene that is equivalent to obtain is suitable/be rotated counterclockwise 0 degree.On the other hand, this apex coordinate in the scene can be rotated counterclockwise 20 the second apex coordinates of spending to produce for right eye.
Should be appreciated that, the above has only provided the example of rotation mode and the anglec of rotation, the invention is not restricted to above-mentioned concrete example.
Rotation mode according to top the first example to the four examples, in the situation of the upper left corner as the initial point in the cross section of each depth of field/degree of depth with scene, namely, (X in the position, the upper left corner of scene, Z) coordinate is (0,0) in the situation, is equivalent to Z axis in the XZ plane of scene as the rotary reference axle.
In the case, can calculate postrotational apex coordinate (comprising the first apex coordinate and the second apex coordinate) according to following formula.
Apex coordinate can be represented as usually
The projection matrix M of apex coordinate can be represented as

For example, in the situation that select in the XZ plane the corresponding line of X=X0 as the rotary reference axle, can be first with the corresponding line of X=X0 in this XZ plane as new X-axis, and correspondingly change X coordinate figure in the apex coordinate, and then be rotated conversion.Particularly, can at first the X value of this apex coordinate be changed into X-X0, and then be rotated conversion.
Similarly, also can similarly change for Z axis, no longer give unnecessary details at this.
In the situation that with the corresponding line of X=X0 as the rotary reference axle,
The first example:

The second example:
First apex coordinate that the arbitrary apex coordinate in the scene can be used for left eye with respect to this rotary reference axle clockwise (the first direction of rotation) rotation 5 degree (first anglec of rotation) with generation, and can be with this apex coordinate in the scene with respect to this rotary reference axle counterclockwise (the second direction of rotation) rotation 25 degree (second anglecs of rotation, at this moment, be not equal to first anglec of rotation) to produce the second apex coordinate that is used for right eye.
The 3rd example:
First apex coordinate that the arbitrary apex coordinate in the scene can be used for left eye with respect to this rotary reference axle counterclockwise (the first direction of rotation) rotation 2 degree (first anglec of rotation) with generation, and can be with this apex coordinate in the scene with respect to counterclockwise (the second direction of rotation of this rotary reference axle, at this moment, with the first direction of rotation) rotation 20 degree (second anglecs of rotation, at this moment, be not equal to first anglec of rotation) to produce the second apex coordinate that is used for right eye.
The 4th example:
Can be with this vertex data in the scene that obtains with first apex coordinate that act on left eye, at this moment, this vertex data in the scene that is equivalent to obtain with respect to this rotary reference axle suitable/be rotated counterclockwise 0 degree.On the other hand, this apex coordinate in the scene can be rotated counterclockwise 20 the second apex coordinates of spending to produce for right eye with respect to this rotary reference axle.
