Step S300: the 3-D graphic is shown.
The scheme of the application will be specifically described below.
Step S100: obtaining multiple X-Y schemes, and obtains every two X-Y scheme in the multiple X-Y scheme and exist
Relative positional relationship in space.
Can have on electronic equipment as interactive interface and display interface, then user be based on interactive interface can be to electronics
Equipment tablet pattern draws operation, for example, user can be realized by operation keyboard or mouse to electronic equipment tablet pattern
Draw operation.Correspondingly, electronic equipment can respond the graphic plotting operation of the user's input detected, electronic equipment is based on certainly
The data-handling capacity of body can then generate and according to the graphic plotting operation detected by display interface, such as display screen
Show corresponding X-Y scheme.
It is understood that in practice, the interactive interface and display interface of electronic equipment may be an interface, example
Such as, in the case where electronic equipment is tablet computer, the liquid crystal display of electronic equipment just has the function of interaction and display.
In this present embodiment, when user needs drawing 3 D graphics on an electronic device, user can be first in electronic equipment
On draw out X-Y scheme.Optionally, user is also possible to based on the interactive interface on electronic equipment to electronic equipment input figure
Shape draws operation, is a lasting process due to drawing X-Y scheme, then the response detection that electronic equipment can then continue
The graphic plotting operation arrived, and be continuously generated and show corresponding X-Y scheme in the display interface.
In the present embodiment, a 3-D graphic can have multiple faces, then user then needs to operate by graphic plotting
To draw out the X-Y scheme in each face in 3-D graphic comprising pattern.In this way, the lasting response figure of electronic equipment is drawn
System operation, so that it may generate and obtain multiple X-Y schemes that are corresponding with graphic plotting operation and needing to draw out for user.
It is assumed that needing the 3-D graphic drawn is video wall, and in 6 faces of the video wall, front has pattern, and just
Also there is pattern on the adjacent side of left and right two in face, and it is remaining with it is positive with respect to and parallel reverse side and with positive phase
Adjacent two sides up and down do not have pattern then.So, it includes: that tool is figuratum just that user, which needs the X-Y scheme drawn then,
Face, the figuratum left side of tool and the figuratum right side of tool.
For convenient for being subsequently generated 3-D graphic, user be can also continue to based on carrying out figure on the interactive interface on electronic equipment
Shape draws operation and inputs the relative positional relationship of every two X-Y scheme in space in multiple X-Y schemes to electronic equipment.
In this way, electronic equipment is operated also based on the graphic plotting is responded, so that it may obtain the user and input every two in multiple X-Y schemes
The relative positional relationship of a X-Y scheme in space.
It is assumed that electronic equipment generates and the multiple X-Y schemes obtained are the figuratum front of tool of the video wall, have
The left side and the figuratum right side of tool of pattern.So, every two X-Y scheme exists in multiple X-Y schemes of user's input
Relative positional relationship in space then can be with are as follows: have figuratum left side with have figuratum positive left side and connect and vertical
Directly in having figuratum front, has figuratum right side and connect and with having figuratum positive right edge perpendicular to figure
The front of case.
It should be noted that if the height for having any one X-Y scheme that can indicate the 3-D graphic in multiple X-Y schemes
Perhaps thickness so user is then not necessarily to define the height or thickness of 3-D graphic.If but not any in multiple X-Y schemes
A X-Y scheme can indicate the height or thickness of the 3-D graphic, for example, multiple X-Y schemes be video wall front and with
The capable back side is commented in front, then user just needs for the height of 3-D graphic or thickness to be input in electronic equipment, so that electronics
Equipment also obtains the height or thickness of the 3-D graphic.
Step S200: according to the relative positional relationship of the multiple X-Y scheme and every two X-Y scheme in space,
Construct the 3-D graphic being made of the multiple X-Y scheme.
For electronic equipment during obtaining multiple X-Y schemes, electronic equipment is according to default analysis program to multiple two dimensions
Figure carries out lasting parsing, then electronic equipment is obtained with multiple features of each X-Y scheme in multiple X-Y schemes
Data, wherein characteristic is on corresponding X-Y scheme: the apex coordinate of figure, circular central coordinate of circle and radius length,
At least partly coordinate in the extreme coordinates and control point coordinates of arc.It is understood that due to the figure on each X-Y scheme
Shape moulding and/or pattern are different, so that the characteristic on each X-Y scheme is at least partly coordinate in above-mentioned coordinate.
In the present embodiment, has the advantages that strong flexibility due to ThreeJS engine and low, therefore electronics is required to equipment performance
Equipment can automatically generate 3-D graphic by ThreeJS engine, then the ThreeJS engine can be pre-installed in the electricity
In sub- equipment.
As a kind of mode optionally, electronic equipment can call and run the ThreeJS engine, allow to basis
Multiple characteristics, preset index relative and the preset normal relationship of each X-Y scheme, can be in three-dimensional system of coordinate
Establish corresponding each X-Y scheme, it can be interpreted as each X-Y scheme being mapped in three-dimensional system of coordinate.Electronics is set
It is standby to continue to run the ThreeJS engine, then the ThreeJS engine can be according to the phase of every two X-Y scheme in space
To positional relationship, the three-dimensional figure being made of multiple X-Y schemes in the three-dimensional system of coordinate is constructed in the three-dimensional system of coordinate
Shape.
It is understood that since multiple X-Y schemes all have built up in the three-dimensional system of coordinate, then construct this three
The process of dimension figure then can be understood as the relative positional relationship based on every two X-Y scheme in space, by multiple two dimensions
The process that figure is spliced.Further, since multiple X-Y schemes are to have figuratum face in 3-D graphic, it may not be three
Tie up face all in figure.So, during constructing 3-D graphic, other faces without pattern then may be used in 3-D graphic
To be generated accordingly based on the relative positional relationship of every two X-Y scheme in space.
It should be noted that if the data of user's input further include the height or thickness of the 3-D graphic, then building three
Tieing up the process of figure then can be for first based on every two X-Y scheme relative positional relationship in space by multiple X-Y scheme
In three-dimensional system of coordinate be arranged after, then based on height or thickness adjust the mutual distance of multiple X-Y schemes, to be formed
The 3-D graphic.
Step S300: the 3-D graphic is shown.
In the present embodiment, electronic equipment can be shown 3-D graphic based on the Flash client of installation, but Flash
The 3-D graphic that client can not directly generate ThreeJS engine is shown, therefore electronic equipment is needed to the 3-D graphic
It formats.
Optionally, which can be switched to can to show by ThreeJS engine according to preset conversion program
BufferGeometry model data, and include in the threedimensional model in the bufferGeometry model data: all faces
Characteristic, the normal relationship of the index relative in each face and each face.Correspondingly, the Flash client on electronic equipment
The bufferGeometry model data is obtained, and the interior rendering engine of the Flash client is based on bufferGeometry mould
The three-dimensional then can be generated in the normal relationship in the characteristic in all faces in type data, the index relative in each face and each face
Figure, such electronic equipment then show the 3-D graphic in the display interface of the Flash client.It even, is raising
User experience, the angles of display of user's also adjustable 3-D graphic.
