Embodiment two
Fig. 2 is the flow diagram of the methods of exhibiting of point of interest provided by Embodiment 2 of the present invention.The present embodiment is with above-mentioned
It optimizes based on embodiment, in the present embodiment, is turned the position of the point of interest according to the position relationship by described
Screen coordinate is changed to, is specifically optimized for：Rotation translation unit matrix is established, and sets the ginseng of the rotation translation unit matrix
Number, the parameter include view center, viewpoint and vector definition upwards；According to the orientation to the rotation translation unit matrix
Rotation transformation is carried out, and translation transformation is carried out to the rotation translation unit matrix for completing rotation transformation according to the distance；It establishes
General perspective unit matrix, and according to the viewport parameter setting of setting general perspective unit matrix six face parameters；According to
It completes the translation of the rotation after translation transformation unit matrix, general perspective matrix and viewport parameter and determines conversion parameter；According to described
Conversion parameter determines the screen coordinate of the point of interest.
Correspondingly, the methods of exhibiting of point of interest provided in this embodiment, including：
Step 210 determines point of interest and the position relationship of terminal, and the position relationship includes：Range-azimuth.
Step 220 establishes rotation translation unit matrix, and sets the parameter of the rotation translation unit matrix, the ginseng
Number includes view center, viewpoint and vector definition upwards
Conversion for coordinate mathematically can be defined and realized using the method for matrix operation.With expression matrix
Formula is come when calculating these conversion, translation is that matrix is added, and rotation and scaling are then matrix multiples, and p ' can be expressed as by integrating
=m1*p+m2 (m1 rotates scaled matrix, and m2 is translation matrix, and p is former vector, and p ' is the vector after conversion).The rotary flat
It is a kind of default matrix provided in Android (Android) system development bag to move unit matrix, is usually the unit of a 4*4
Matrix.It can be the matrix for being converted to the virtual world in screen.If will to the object in virtual world into
Row rotation, transfer or change in size are required for translating unit matrix using the rotation.Wherein, the rotation translation unit square
3 components in battle array are used to represent X, Y and Z component under three-dimensional system of coordinate.It is 3-dimensional to carry out a script using the 4th component
Vector is represented with 4 dimensional vectors.Usually there are X=x/w, Y=y/w and Z=z/w.Mark three-dimensional corresponding one of the mark of making
Amount, is a unit matrix.Any one point v, coordinate v '=Mv after coordinate transform in corresponding space.
Further, since it is to need to be converted to screen coordinate, it is necessary to set the ginseng of corresponding rotation translation unit matrix
Number.The parameter of the rotation translation unit matrix can include：View center, viewpoint and vector definition upwards.The viewpoint can
To be the position of user's viewing, since the position of user's viewing influences the arrangement of image, it is therefore desirable to define viewpoint.Due to terminal
Distance with the point of interest is d, then can be arranged to viewpoint ((0,0 ,-d)).View center determines the center of rotation,
It therefore, can be centrally disposed for (0,0,0) by view.And under normal viewing, user head-up, corresponds to screen
Positive direction of the y-axis, so in this case, it is therefore desirable to which definition vector definition upwards is worked as specifically, could be provided as (0,1,0)
So (0,1,0) is a unit vector.
Step 230 carries out rotation transformation according to the orientation to the rotation translation unit matrix, and according to the distance
Translation transformation is carried out to the rotation translation unit matrix for completing rotation transformation.
Due to point of interest with terminal there are gun parallax, it is necessary to be rotated to it.Therefore, can be calculated according to the above method
Obtained orientation carries out rotation transformation to the rotation translation unit matrix.Illustratively, the rotation can be translated unit
Matrix is rotated in X-direction, and the angle of rotation is the corresponding angle a in the orientation.It, can be according to institute after completing to rotate
It states point of interest to be translated with the distance between terminal d, since d is relative distance, can be carried out by affine transformation
Translation transformation.Illustratively, the rotation for completing rotation transformation can be translated unit matrix to be multiplied by array (0,0, d, 1) complete
Into translation transformation in the Z-axis direction.Illustratively, the rotation translation unit matrix after completion rotation transformation is multiplied by array
(0,0, d, 1) can obtain array F1=(f0, f1, f2, f3)
It is because if first being translated, in the view of the rotation why by the way of first rotating and translating afterwards
The heart is accordingly changed, and the result rotated is different from first being rotated the result translated afterwards.In view of reality
In the process, revolved view center should not convert, it is thus impossible to using first translating the calculation rotated afterwards.
Step 240 establishes general perspective unit matrix, and the general perspective unit according to the viewport parameter setting of setting
Six face parameters of matrix.
Similar, the general perspective unit matrix is also a kind of default matrix provided in Android system development kit,
The usually unit matrix of a 4*4.The purpose of projection be equivalent to three-dimensional geometry body is converted into one kind can be as two dimensional image
The form rendered.The general perspective can be that all projection lines are all vertical with final drawing surface.The reality of object is big
Small and projection size remains unchanged.Using general perspective unit matrix, the three-dimensional coordinate of point of interest can be projected to screen
On position.The general perspective unit matrix needs to set six face parameters, and the effect of the six faces parameter is one cuboid of setting,
Object only in cuboid can be just projected on screen.Six face parameter can be determined according to viewport parameter.The viewport
It can be the size of the client area in screen for viewing.The viewport parameter can be the height and width of client area.Optionally, root
Viewport parameter is set according to screen size.In the present embodiment, for display effect the considerations of, is typically carried out with state all over the screen
Display.Correspondingly, the screen of setting screen a height of w, width h, under state all over the screen, six set face parameters are specifically as follows
(- 0.25,0.25, -0.25/w*h, 0.25/w*h, 0.1,2*d), wherein, -0.25 is the left side of the cuboid, described 0.25
For the right side of cuboid ,-the 0.25/w*h is the bottom surface of cuboid, and the 0.25/w*h is the top surface of cuboid, described 0.1
For nearly face, the 2*d is remote face, why remote face is arranged to 2*d, it is contemplated that the cuboid is allowed for the interest
Point is included, and therefore, is set as 2*d, to ensure the point of interest in the cuboid.
Step 250, the rotation translation unit matrix according to after completion translation transformation, general perspective matrix and viewport parameter are true
Determine conversion parameter.
The conversion parameter can be model (M), view (V), the synthesis for projecting (P) three kinds of matrixings.I.e.
MVPMatrix=PrijectionMatrix*ViewMatrix*ModelMatrix*vertex.Each point is equivalent to first to carry out
Model conversion (rotation of translation scaling) carries out view transformation and projective transformation again.
Illustratively, the rotary flat completed after translation transformation that the general perspective matrix and the above method can be obtained
The array F1 for moving unit matrix is multiplied, and obtains another array F2 (f4, f5, f6, f7).Then, f7 is subjected to assignment again, by f7
It is assigned a value of 1/-f2.If f2 is 0, illustrate the coordinate of the point of interest not in screen.By the f4, f5, f6 respectively with
F7 after duplication is mutually multiplied, and obtains new f4, f5, f6.The position of the point of interest can be calculated using aforesaid way
Correspondence of the coordinate after translation transformation and projection with screen coordinate.But above-mentioned parameter is to carry out computing according to unit to obtain
, therefore, it is also desirable to be converted into corresponding screen coordinate system.Therefore, it is also desirable to which viewport parameter determines conversion parameter.Example
Property, array V=(0,0, w, h) is established according to the height and width of the viewport, the w is Viewport height, and the h is wide for viewport
Degree.When carrying out display all over the screen, the w can be screen height, and the h is screen width.
Step 260, the screen coordinate that the point of interest is determined according to the conversion parameter.
Illustratively, the screen coordinate of the point of interest can be calculated in the following way：
X=(f4*0.5+0.5) * V [2]+V [0], y=V [3]-((f5*0.5+0.5) * V [3]+V [1]).
Why the calculation formula of X-coordinate needs to be multiplied with V [2] i.e. W, is because above-mentioned f4*0.5+0.5 is a normalizing
The coefficient of change, for numeric distribution between (0,1), therefore, it is necessary to be converted into screen coordinate.Such as：Using situation all over the screen as
Example, f4*0.5+0.5 0.7, the height of the screen is 1000, then corresponding screen x coordinate is then 700.And calculating y's
In the process, since coordinate (0, the 0) point of screen is located at the upper left corner of screen, therefore, it is necessary to its height subtract the coefficient with
The product of height.
The position of the point of interest is converted to screen coordinate by the present embodiment by described according to the position relationship, specific excellent
It turns to：Rotation translation unit matrix is established, and sets the parameter of the rotation translation unit matrix, the parameter is included in view
The heart, viewpoint and vector definition upwards；Rotation transformation is carried out to the rotation translation unit matrix according to the orientation, and according to institute

Step 320 establishes rotation translation unit matrix, and sets the parameter of the rotation translation unit matrix, the ginseng
Number includes view center, viewpoint and vector definition upwards.
Step 330 obtains screen turning steering magnitude by being configured at the gyroscope of terminal.

Step 340 carries out rotation change according to the orientation and screen turning steering magnitude to the rotation translation unit matrix
It changes, and translation transformation is carried out to the rotation translation unit matrix for completing rotation transformation according to the distance.
In user's using terminal, especially in gait processes, it is difficult to ensure that terminal is in a normal placement state,
The normal placement state can include：The screen vertical of terminal is in horizontal plane, and terminal screen upper and lower side frame is parallel to level
Face.When terminal is in and deflects or is tilting, since screen generates offset, the screen coordinate of the point of interest also can phase
Variation should be generated.Therefore need to turn to magnitude according to the screen turning and the method determines the screen coordinate of point of interest.
When terminal rotates, the three-dimensional coordinate that can be regarded as the point of interest is rotated, therefore, can basis
The orientation and screen turning turn to magnitude and carry out rotation transformation to the rotation translation unit matrix.Illustratively, according to above-mentioned
It is respectively (r0, r1, r2) that method and step, which can determine that screen turning turns to magnitude, then the rotation is translated unit matrix exists respectively
[1,0,0], [0,1,0], [0,0,1] rotation r1+a, r0, r2.
