Below in conjunction with specific embodiment concrete realization of the present invention is described in detail:

Embodiment one:

Fig. 1 shows the realization flow of the disposal route of the Application Program Interface that first embodiment of the invention provides, and details are as follows:

In step S101, obtain the original interface length breadth ratio and the target interface length breadth ratio of application program.

In the practical implementation process; Because the original interface of same application often pre-sets an original best-fit screen resolution; And this application program often need be installed in the middle of the different systems; All might there be the perhaps length breadth ratio of different interface display of different resolution in the different interfaces of same system platform or the different interfaces of different system platform; If the display interface with the different resolution of different system platform is an example; When pre-setting this application program one original best-fit screen resolution; This best-fit screen resolution can adaptive a certain system platform, and when on the system platform that this application program is installed to another concrete different resolution, the disposal route that then need utilize the embodiment of the invention to provide is at first obtained the original best-fit screen resolution of this application program; And the resolution of from current system platform, obtaining the target device physical screen; Such as 720P, 1080P etc., then can obtain this target interface length and width ratio easily according to the resolution of target device physical screen, the resolution of this target device physical screen or title target interface resolution are meant the screen resolution of the portable terminal support that this system platform is installed.Generally speaking; In this application program use; Can detect the resolution of the display interface that obtains physical screen automatically, if can not obtain through the application program interface function of calling system platform according to interface function; Generally speaking, it is identical with the screen physical resolution manual this target interface resolution to be set.And the step of obtaining the original interface length breadth ratio of application program is specially the original interface length breadth ratio of obtaining application program according to original best-fit screen resolution, promptly can obtain screen aspect ratio according to the long dimension of this resolution and the Pixel Information of wide dimension.

In step S102; When the original interface length breadth ratio of judging this application program and this target interface length breadth ratio not simultaneously; According to the magnitude relationship between this original interface length breadth ratio and this target interface length breadth ratio, obtain the displacement parameter of object in visual coordinate system on the original interface of this application program.

In the practical implementation process; Need to judge whether this target interface length breadth ratio that gets access to is identical with the original interface length breadth ratio of this application program; When being judged as when identical; Then need not make any change this moment to the coordinate figure of the object on this Application Program Interface in the view plane coordinate system; Can be the view plane coordinate with the current coordinate projection of the object on this Application Program Interface in this visual coordinate system directly, be tied to the coordinate transform relation of target interface screen coordinate system again based on the view plane coordinate, be this target interface screen coordinate with this view plane coordinate conversion; The original best-fit screen resolution of the target interface resolution of current system platform for this application program perhaps directly is set, so that the target interface of Application Program Interface and system platform adapts.

In step S103,, adjust the coordinate of this object in this visual coordinate system according to this displacement parameter.

In this step S102:

Length, the width of remembering original interface are respectively Lp, Wp, and the length of target interface, width are respectively Ls, Ws, if judge Lp/Wp and Ls/Ws all greater than 1 or all less than 1 o'clock, this displacement parameter is (Lp/Wp)/(Ls/Ws);

Then this moment, this step S103 specifically may further comprise the steps:

If (Lp/Wp) greater than (Ls/Ws), then adjusting the Y axial coordinate y of this object in visual coordinate system is y ', y '=y * displacement parameter;

If (Lp/Wp) less than (Ls/Ws), then adjusting the X axial coordinate x of this object in visual coordinate system is x ', x '=x * displacement parameter.

As the present invention's one instance, this step S102 is specially:

Length, the width of remembering original interface are respectively Lp, Wp, and the length of target interface, width are respectively Ls, Ws, if judge Lp/Wp and Ls/Ws one of them greater than 1, another was less than 1 o'clock, this displacement parameter is (Wp/Lp)/(Ls/Ws);

Then this moment, this step S103 specifically may further comprise the steps:

If (Wp/Lp) greater than (Ls/Ws), then adjusting the Y axial coordinate y of this object in visual coordinate system is y ', y '=y * displacement parameter;

If (Wp/Lp) less than (Ls/Ws), then adjusting the X axial coordinate x of this object in visual coordinate system is x ', x '=x * displacement parameter.

In embodiments of the present invention; For convenience; Below with the original interface of this application program or claim that length, the width at the interface that the best-fit screen resolution is corresponding represent with Lp, Wp respectively; And the target interface of this application program system to be installed or physical screen length, width represent with Ls, Ws that respectively then this original interface length breadth ratio and this target interface length breadth ratio are represented with Lp/Wp and Ls/Ws respectively.

Particularly; If original best-fit screen resolution size 720P that application program is preset; This application program is installed in the goal systems platform that target interface resolution is 1080P; The perhaps current interface of application program size 1080P is installed in the situation in the goal systems platform of 720P with it, if corresponding interface length breadth ratio and this target interface length breadth ratio of original best-fit screen resolution that should be preset is 16: 9; Then because their length breadth ratio is identical; The ratio (Lp/Wp)/(Ls/Ws) of this current interface length breadth ratio and this target interface length breadth ratio is 1, and the displacement parameter of object in the view plane coordinate system on this Application Program Interface is the ratio of this original interface length breadth ratio and this target interface length breadth ratio so, and also promptly this displacement parameter is 1; Thereby need not make any change to the coordinate figure of this object in the view plane coordinate system, only need directly carry out the coordinate step that the imaging of this application program on the view plane is converted on the target interface screen and get final product.

Particularly; When this original interface length breadth ratio and this target interface length breadth ratio all greater than 1 or all less than 1 the time, if also promptly Lp/Wp and Ls/Ws are divided into following two kinds of situation all greater than 1 perhaps all less than 1 o'clock; Suppose that the coordinate of object p under visual coordinate system is (x; Y), adjusted coordinate is (x ', y '):

1) if. Lp/Wp is greater than Ls/Ws; Explain that then this application program is on the screen of broad that compares, to move; If do not do any operation this moment, then final effect such as the same fat person who shows drawn high by broad ways, and this moment, camera camera remained unchanged from the distance of view plane; Because Aspect Ratio changes Ls/Ws into, need the ordinate y value of this object in visual coordinate system increased.Therefore the object of view frustums the inside should be done corresponding mobile; Be appreciated that for actual object move to y ' position along Y axial coordinate direction, otherwise possibly can't show that is: displacement parameter is (Lp/Wp)/(Ls/Ws); Y '=y * (Lp/Wp)/(Ls/Ws); And the x value is constant, and adjusted respective coordinates is (x, y ').

2) if. Lp/Wp is less than Ls/Ws, and then explanation is will operate on the relatively narrow screen to move, if do not do any operation this moment; Then final effect that shows such as same lean person by along length to elongation, for head it off, need the x value of this object is diminished; Therefore the object of view frustums the inside should be done corresponding mobile, otherwise possibly can't show, reduces X axial coordinate value; That is: x '=x * (Lp/Wp)/(Ls/Ws); And the y value is constant, the coordinate of adjusted correspondence in visual coordinate system be (x ', y).

Particularly, in this original interface length breadth ratio and this target interface length breadth ratio one another is greater than 1 o'clock less than 1, if also promptly there is among Lp/Wp and the Ls/Ws one also to be divided into two kinds of situation less than 1 o'clock, as following greater than 1, one:

In this preset original interface length breadth ratio and this target interface length breadth ratio one less than 1; Another was greater than 1 o'clock; If also promptly have among Lp/Wp and the Ls/Ws one greater than, one less than 1 o'clock, also is divided into following two kinds of situation; Then at first need be with the object in 3D or the 2.5D Application Program Interface; Be the axle center to anticlockwise 90 degree all with view plane normal vector direction as shown in Figure 2 (camera coordinates is the Z axle), then this each object again with separately center Z axle be the axle center to right rotation 90 degree, carry out as judging after being provided with:

1) if. Wp/Lp is greater than Ls/Ws, explains that then this application program is will operate on the screen of the broad that compares to move, if do not do any operation this moment, then final effect such as the same fat person who shows drawn high by broad ways.Camera remains unchanged from the distance of view plane at this moment; Because Aspect Ratio need change Ls/Ws into; Therefore the object of view frustums the inside should be done corresponding mobile, otherwise then possibly can't show, so only need the y axial coordinate is increased; Be adjusted into: y '=y * (Wp/Lp)/(Ls/Ws), the x coordinate figure is constant.

2) if. Wp/Lp is less than Ls/Ws; Then explanation is will operate on the relatively narrow screen to move, and this moment, camera remained unchanged from the distance of view plane, because Aspect Ratio need change Ls/Ws into; Then need the object of view frustums the inside should be done corresponding mobile; So only need the x axial coordinate is diminished, be adjusted into: x '=x * (Wp/Lp)/(Ls/Ws), the y coordinate figure is constant.

And then, can obtain the coordinate of all objects after the renewal under the visual coordinate on this Application Program Interface.
