Specific embodiment
The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although the disclosure is shown in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
Completely it is communicated to those skilled in the art.
Two-dimensional image or three-dimensional image, image are made of in itself many picture points, picture point
Quantity generally determined by the pixel quantity of painting canvas.In visual angle, picture point is in two-dimensional image
Coordinate and the coordinate in three-dimensional image, between the two with correspondence, this correspondence can be by picture material
Practical significance determine, can also be obtained by artificial or program setting.Such as in world map shown in Fig. 1, two dimensional surface
The image point coordinates of Madagascar is corresponded in map, corresponded to three-dimensional image Madagascar image point coordinates it
Between just as belong to same longitude and latitude place on practical significance and with correspondence；In chart shown in Fig. 2, two dimension
The image point coordinates in the corresponding square lower right corner tries hard to correspond to the image in the cube lower right corner in image with three-dimensional in flat image
Point coordinates, the two belong to the same apex angle of cube structure, therefore with correspondence on practical significance.The present embodiment is
It is the correspondence based on image point coordinates, all picture points in image is synchronously carried out path movement, so as to fulfill figure
The transition switching of picture.For ease of expressing and understanding, the embodiment of the present invention will subsequently be carried out by taking a picture point in image as an example
Explanation.
An embodiment of the present invention provides a kind of model space geometric image switching method, as shown in figure 3, this method includes：
301st, first coordinate of the picture point in former dimension image and the second coordinate in target dimension image are obtained.
In the present embodiment, former dimension image can be different from the image dimension of target dimension image, such as former dimension image
For two-dimensional image, target dimension image is for three-dimensional image or on the contrary.By to former dimension image and target dimension
Two-dimensional image transition can be switched to three-dimensional image or cut three-dimensional image transition by the setting of image
It is changed to two-dimensional image.In addition, former dimension image can also be identical with the image dimension of target dimension image, such as by one
Three-dimensional graph switching (transformation) for another three-dimensional graph or switches over different 2-d plane graphs.
As previously mentioned, picture point has corresponding close in two-dimensional image between the coordinate in three-dimensional image
System, in drawing image, not only it needs to be determined that the coordinate of each picture point, it is also necessary to correspondence between above-mentioned coordinate into
Row mapping.In a kind of feasible realization method, have and manually establish the correspondence, it should be noted that this correspondence
The foundation of relationship is not to be directed to each picture point (workload is excessively huge), but by computer program in image
Hold the relationship that structure carries out to establish.For example, establish a line respectively in two-dimensional image with the position in three-dimensional image
It puts correspondence or to establish house overall profile corresponding with the position in three-dimensional image in two-dimensional image respectively
Relationship etc..And in another implementation, dedicated drawing tool pair in the specific function library in drawing software can be passed through
Picture material in two-dimensional image and three-dimensional image carries out automatic identification, and pass through meter on the basis of content recognition
Calculation machine program carries out the foundation of correspondence automatically.
It should be noted that when carrying out the switching of identical dimensional image, the picture point that is not necessarily in two images
With the identical practical significance similar to longitude and latitude, such as when three-dimensional square is switched to three-dimensional sphere, in sphere image
There is no the concept of cube apex angle, homogeneity of the coordinate based on certain practical significance without requiring two images is closed
Connection.In practical application, it can be manually set between the first coordinate and the second coordinate according to the switching deformation effects for wishing to obtain
Correspondence.
In the present embodiment, when carrying out the switching of across dimension image, either two-dimensional image or three-dimensional image,
Established in same coordinate system.The purpose established in same coordinate system is to facilitate between two kinds of dimension images
The transition and conversion of coordinate；And the purpose established in three-dimensional system of coordinate is then, unified two-dimensional image and 3 dimensional drawing
The coordinate dimensions of picture point as in, so as to facilitate comparison and calculating between two kinds of coordinates.In practical application, three-dimensional system of coordinate can
To draw two-dimensional image and three-dimensional image, and two-dimensional coordinate system can only then draw two-dimensional image, thus across
It needs to use three-dimensional system of coordinate in dimension image handoff scenario.When carrying out Image Rendering using three-dimensional system of coordinate, two dimensional surface
The image point coordinates of image is shaped like (X1, Y1, Z1), and the image point coordinates of three-dimensional planar image is shaped like (X2, Y2, Z2), both
On X-axis, Y-axis and Z axis there is component, can directly correspond to calculating；And if drawing 2 d plane picture in two-dimensional coordinate system
Picture, the drawing three-dimensional stereo-picture in three-dimensional system of coordinate, then because of coordinate between coordinate (X1, Y1) and coordinate (X2, Y2, Z2)
The difference of dimension just can not be calculated directly.
It should be noted that refer to paint based on same three-dimensional system of coordinate drafting two-dimensional image and three-dimensional image
Coordinate system used in two kinds of images of system is same coordinate system rather than in a coordinate system while draws out 2 d plane picture
Picture and three-dimensional image when performing image display, also only show one kind in two kinds of images, this is that across dimension image is cut
The basis changed.
It, can be with if two images are two-dimensional image in addition, when being switched over to identical dimensional image
Selection carries out image foundation in two-dimensional coordinate system, if two images are three-dimensional planar image, needs in three-dimensional coordinate
Image foundation is carried out in system.
In the present embodiment, it can be, but not limited to draw two-dimensional image and three-dimensional image using WebGL language.
WebGL is a kind of 3D drafting standards, and this drafting standards permission is combined together JavaScript and OpenGL ES 2.0,
It is bound by a JavaScript for increasing OpenGL ES 2.0, the painting canvas for html page provides hardware 3D and accelerates to render,
So as to show 3D rendering more glibly in browser by system video card.After three-dimensional system of coordinate is established in initialization, designer
Member manual setting be used for form line some point positions, then drafting instrument can be based on these point automatically generate line and
Face, so as to obtain three-dimensional image.Foundation for picture point coordinate correspondence relationship in two kinds of dimension images, then be not belonging to
The function that WebGL language carries in itself, the present embodiment can be defined the function by way of writing self defining programm
And realization, such as the practical significance with the attribute information characterization picture point display content of some dimension of picture point, according to the dimension
It spends attribute information and searches first coordinate and second coordinate of the picture point in two images, and pass through customized data structure storage
Mapping relations between picture point, the first coordinate, the second coordinate three.
After the first coordinate and the second coordinate of picture point is read from data structure, step 302 is performed.
302nd, it calculates from the first coordinate to the mobile route of the second coordinate.
It, can be directly according to two point coordinates since the first coordinate and the second coordinate are in same three-dimensional system of coordinate
(X1, Y1, Z1), (X2, Y2, Z2) calculate mobile route.Mobile route can be designed as to straight line or curve in practical application, when
When mobile route is curve, need to be converted the mobile route of form of straight lines according to preset curve equation.The present embodiment
The specific form of picture point mobile route is not limited.
303rd, the moving coordinate of the corresponding picture point of each picture frame on the mobile route is calculated.
The line segment that mobile route is made of many a points, the coordinate of each point is exactly picture point institute on different moments
The position at place.The continuous process of the second coordinate is transitioned into express picture point from the first coordinate, by multiple in the present embodiment
Picture frame is shown the process.Wherein, each picture frame shows a seat of the picture point on mobile route for drafting
Cursor position, i.e., coordinate position at the time of current image frame corresponds to where epigraph point.The picture point that different images frame is shown
Position with picture frame replacement, move along path extension.By the continuous drafting of more picture frames, image can be shown
Point is moved to the process of the second coordinate according to mobile route from the first coordinate.
304th, it will show that the picture frame of picture point is continuously plotted on painting canvas according to the moving coordinate, obtain former dimension figure
As transition is switched to the dynamic effect of target dimension image.
Each picture frame corresponds to a moment value, moving coordinate of each moment value epigraph point on mobile route
It is different, increases over time and the continuous drafting of picture frame, generation picture point move along what path was constantly moved
Dynamic effect.After one frame image of every calculating, it is plotted on painting canvas and rendering displaying is carried out to painting canvas.It is then followed by calculating
And next frame image is drawn, after all picture frames all draw displaying, picture point is moved to the second coordinate position, completes
The switching of image.
In the present embodiment, the image frames numbers that handoff procedure uses switch duration by expected image and frame per second determines, have
Image frames numbers=image switching duration * frame per second for body.Wherein, the time of image switching duration representative image dynamic transition is long
It is short, it can freely be set according to actual demand；The size of frame per second can be according to smoothness (smoothness) effect to dynamic transition
Difference require unrestricted choice.In general, the smoothness of frame per second more Larger Dynamic transition is better, the present embodiment is not to both above-mentioned index
Concrete numerical value limited.
It is to be illustrated by taking the moving process of a picture point as an example above, in practical application, when simultaneously to all figures
The coordinate position that all picture points are engraved when corresponding to can be all shown when picture point is moved, in each picture frame, passes through image
The continuous of frame draws the transition transition effect for realizing former dimension image to target dimension image entirety.
In addition, so-called painting canvas in the present embodiment, one for being independently of html page and being located at below html page paints
Figure figure layer.By taking common canvas painting canvas as an example：Canvas painting canvas is a kind of drawing label provided in html language, browser
By establishing the drawing label initialization canvas painting canvas.It can be in canvas painting canvas according to information preset in script file
In the range of, the attributes such as the position of each picture point, size, color, transparency are configured, so as to fulfill painting for picture point
System, and the composition of multiple images point can then form a picture pattern.In the present embodiment, browser on painting canvas by changing
The mode of picture point coordinate position realizes movement of the picture point from former dimension image to target dimension image.
Further, the embodiment of the present invention additionally provides a kind of model space geometric image switching method, this method with across
It is illustrated for the switching of dimension image.As shown in figure 4, this method includes：
401st, according to the picture point attribute of default dimension, same figure is searched in former dimension image and target dimension image
Picture point.
402nd, coordinate of the picture point in former dimension image and in target dimension image is determined respectively.
Described image point attribute can be the attribute dimensions that picture point shows content, such as in map shown in Fig. 5, can
To determine picture point of the Beijing in former dimension image and in target dimension image according to latitude and longitude coordinates.Finding picture point
Afterwards, the first coordinate corresponding with the picture point and the second coordinate are searched according to the correspondence to prestore.
Further, it is also possible to search picture point according to the pixel property of picture point, such as according to the color of picture point, transparent
The parameters such as degree, brightness identify a picture point.It bears in mind that in two dimension or 3-D view, multiple images point has identical
Pixel property parameter situation it is very universal, it is real to improve the identification of picture point, achieving the purpose that uniquely tagged picture point
In the application of border, the pixel property parameter of different dimensions can be combined use, and the use of pixel-parameters dimension should
With mostly suitable as possible.
403rd, all moving coordinates on the first coordinate to the second coordinate line are calculated by linear difference algorithm, are moved
Dynamic path.
By the execution of step 401 and step 402, the first coordinate and the second coordinate as shown in Figure 6 can be obtained, this two
A coordinate comes from the image of different dimensions but in same three-dimensional system of coordinate.When mobile route is straight line, Ke Yitong
The all the points on linear difference algorithm two coordinate lines of calculating are crossed, thus to obtain all moving coordinates on mobile route.
Illustratively, as shown in Figure 7, it is assumed that the first coordinate is (X1, Y1, Z1), and the second coordinate is (X2, Y2, Z2), then
Can be calculated by linear difference the coordinate of the midpoint M of two coordinate lines for ((X1+X2)/2, (Y1+Y2)/2, (Z1+Z2)/
2).Later, the first coordinate and the coordinate of midpoint N of point M lines and the midpoint O of point M and the second coordinate line are further calculated
Coordinate ... so repeatedly until calculating each moving coordinate of minimum particle size on mobile route.
404th, the corresponding switching progress msg of picture frame is searched.
So-called switching progress msg refers to：Using mobile route entire length as radix, at the time of current image frame corresponds to
In value, length ratio that picture point is moved from the first coordinate position according to from predetermined speed to the second coordinate position.Illustratively,
Dotted line in Fig. 8 represents the entire length of mobile route, and two endpoints M and N represent the first coordinate and the second coordinate respectively.Assuming that
Picture point is moved since first picture frame, according to preset movement speed from M points to N points, then in current image frame institute
At the time of value on, picture point extends to P points from M points, the ratio of line segment MP the line is busy section MN, as above-mentioned switching progress letter
Breath.And the P points position is the moving coordinate of the corresponding picture point of current image frame.
(movement speed for essentially corresponding to setting picture point) can be set in the present embodiment to progress step value,
Such as setting picture point is moved according to the step value of every frame 1%, i.e., it is long for mobile route per the length of frame picture point movement
The 1% of degree.The switching progress msg for corresponding to the picture point of each frame as a result, is followed successively by 1%, 2%, 3%......100%.
After obtaining the first coordinate and the second coordinate, the length of mobile route is calculated according to two point coordinates, it will based on mobile route length
Switching progress is scaled the current path length moved, in the case of known first coordinate and the path length moved,
The moving coordinate of present image point can be calculated, i.e. P point coordinates in Fig. 8.
In addition, in the case where having set image switching duration, it is also based on image switching duration and sets progress automatically
Step value.It is multiplied specifically, can image be switched duration with the frame per second used, obtains the number of image frames that handoff procedure is related to
Amount, is then determined as progress step value by the inverse of image frames numbers.Further, when the quantity for having set picture frame,
Can the inverse of the quantity be directly determined as progress step value.
405th, the moving coordinate of picture point corresponding with picture frame is searched on mobile route according to switching progress msg.
For example, for the first picture frame, moving coordinate 1 is determined according to 1% moving ratio, then on the first picture frame
Moving coordinate 1 position drawing image point；For the second picture frame, moving coordinate 2 is determined according to 2% moving ratio, so
The position drawing image point of moving coordinate 2 on the second picture frame afterwards；For third picture frame, according to 3% moving ratio
Determine moving coordinate 3, then the position drawing image point of the moving coordinate 3 on the second picture frame.So go on, until
Complete the drafting of all picture frames.
In practical application, shape library shading language of increasing income (OpenGL Shading Language, abbreviation can be passed through
GLSL the movement of picture point) is realized.GLSL language is a kind of programming language for pattern coloring, is write using GLSL language
