Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The invention discloses an application scene description and related technical term explanation of a display method and a device of a space dimension mark, which are characterized in that:
the traditional technology can not realize the mutual conversion and synchronous change of the space position marks, and has complex operation; the method and the device can facilitate the operation of the user, and the user can automatically convert and display the space dimension marks in the display diagram only by adding or modifying the marking content once. For example, a user adds a three-dimensional mark on the three-dimensional earth, and when the user switches to the two-dimensional open earth's expanded view, the three-dimensional added mark should be automatically switched over and displayed to the correct position and the correct content. And vice versa.
Preferably, the present invention can be applied to products requiring the mutual transformation of coordinates between a three-dimensional sphere and a corresponding plane (two-dimensional) area, such as a virtual globe; spatial location markers in embodiments of the present invention may include three-dimensional markers and two-dimensional markers; the present invention defines that the mark comprises two characteristics: 1. indicating a position; 2. indicating the content.
The three-dimensional mark may be a mark added with three dimensions in a three-dimensional object or scene, that is, a three-dimensional label in a label style or a bubble style, and records information that needs to be added. The three-dimensional mark is equivalent to a label, and any form of content such as characters, pictures, videos and the like can be added.
A two-dimensional marker may refer to a UI (User Interface) tag added to a two-dimensional scene to indicate the location of the marker and additional information. The two-dimensional tags correspond to labels to which any form of content, such as text, pictures, video, etc., can be added.
Embodiment 1 of the display method of the spatial dimension mark of the present invention:
in order to solve the problem that mutual conversion and synchronous change of different spatial dimension marks cannot be realized when switching display of different spatial dimension display diagrams is performed, the present invention provides a display method embodiment 1 of spatial dimension marks, and fig. 1 is a flowchart of the display method embodiment 1 of spatial dimension marks of the present invention, and as shown in fig. 1, the method may include the following steps:
step S110: acquiring the space dimension type of a display diagram to be switched;
specifically, the display diagram to be switched, i.e. the currently displayed display diagram, may be a two-dimensional expansion diagram or a three-dimensional sphere diagram; the spatial dimension type, that is, the spatial dimension type of the currently displayed presentation graph, may correspond to two dimensions or three dimensions. Furthermore, the space dimension state where the display diagram to be switched is located at present can be recorded through the variable Type inside the program, and then the space dimension Type of the display diagram to be switched is obtained.
Step S120: acquiring current dimensional point coordinates of each target point in the display diagram to be switched according to the space dimensional type of the display diagram to be switched;
specifically, the target point is a point on the to-be-switched display diagram, and the user can mark content or write position information on the target point by clicking or touching the point with a mouse, for example, the user clicks a position to which the user wants to add a mark with the mouse, and a tag can be automatically generated and pointed to the position by the present invention, and the user fills in related content through the tag. The current dimension point coordinates of each target point, namely the point coordinates of the target point on the display diagram to be switched; when the display diagram to be switched is a three-dimensional sphere diagram, the current dimensional point coordinate of the target point is a three-dimensional point coordinate; when the display diagram to be switched is a two-dimensional unfolded diagram, the current dimensional point coordinate of the target point is a two-dimensional point coordinate;
step S130: obtaining a marking coordinate of a target point according to the current dimension point coordinate; acquiring mark content, and generating a current dimension mark of a target point according to the mark content and the mark coordinates;
specifically, the tag includes two characteristics: indicating the location and indicating the content. In each embodiment of the invention, a corresponding mark can be generated according to the point coordinate and the mark content input by the user; for example, a mark without content is generated from three-dimensional point coordinates, a position is indicated, coordinates (i.e., mark coordinates) are generated from the position, and the style of the coordinates and the like are independent of the coordinates, and the content is filled in by the user.
Step S140: converting the current dimension mark according to a preset coordinate conversion rule and the space dimension type of the switched display diagram to obtain a converted dimension mark;
specifically, according to the space dimension type of the switched display diagram, converting the mark coordinates in the current dimension marks into the mark coordinates of the converted dimension marks through a preset coordinate conversion rule; and the space dimension type of the coordinate points in the converted dimension marks is the same as that of the display graph after switching. The preset coordinate conversion rule can be realized by establishing a one-to-one correspondence relationship between two coordinate systems according to different space types of the coordinate systems before and after conversion.
Step S150: and displaying the corresponding target point on the switched display diagram according to the converted dimension mark.
Specifically, a corresponding label may be generated according to the point coordinates in the converted dimension mark and the mark content, and then the corresponding target point (which may be a plurality of target points) is displayed on the switched display diagram.
In a specific embodiment, the step of obtaining the mark content of the mark coordinate and generating the current dimension mark of the target point according to the mark content and the mark coordinate further includes the following steps:
respectively recording each current dimension mark in a preset data structure list corresponding to the display diagram to be switched;
converting the current dimension mark according to a preset coordinate conversion rule and the space dimension type of the switched display diagram to obtain a converted dimension mark, wherein the step of converting the converted dimension mark comprises the following steps:
traversing a preset data structure list corresponding to the display graph to be switched to obtain each marked coordinate;
respectively carrying out coordinate conversion on each mark coordinate according to a preset coordinate conversion rule, and adding the converted mark coordinates into a preset data structure list corresponding to the switched display diagram to obtain each converted dimension mark;
according to the converted dimension marks, the step of displaying the corresponding target points on the switched display diagram comprises the following steps:
traversing a preset data structure list corresponding to the switched display graph, and acquiring each converted dimension mark;
and displaying the target points on the switched display diagram according to the converted dimension marks.
Specifically, the invention can realize the rapid acquisition of the marking data (such as marking coordinates and marking contents) in the spatial dimension marking conversion through the preset data structure list, can improve the accuracy and speed of the dimension marking coordinate conversion, and is convenient for the operation of a user.
In a specific embodiment, the preset data structure list is a hash list.
Specifically, the relevant functions of the preset data structure list can be realized through the hash list; preferably, other data structures may be used to implement the above-described functions, such as two list correspondence records.
The display method of the space dimension mark can solve the problem of mutual conversion between the three-dimensional mark on the three-dimensional sphere and the two-dimensional mark of the two-dimensional expansion map, and realize the synchronous change of the marks with different space dimensions; the invention can greatly simplify the operation of the user, and the user can realize the automatic conversion of the two-dimensional mark and the three-dimensional mark only by adding or modifying the marking content once (namely, in the process of selecting the target point on the display picture to be switched by a mouse or touch).
Embodiment 2 of the method for displaying a spatial dimension mark of the present invention:
based on the technical scheme of the display method embodiment 1 of the spatial dimension mark, meanwhile, in order to solve the problem that mutual conversion and synchronous change of different spatial dimension marks cannot be realized when switching display of different spatial dimension display diagrams is performed, the invention also provides a display method embodiment 2 of the spatial dimension mark, and compared with the technical scheme of the display method embodiment 1 of the spatial dimension mark, the embodiment 2 discusses in detail the process of realizing mutual conversion between a three-dimensional mark on a three-dimensional sphere and a two-dimensional mark of a two-dimensional expansion diagram based on a hash list; fig. 2 is a schematic flow chart of a method for displaying a spatial dimension mark according to embodiment 2 of the present invention.
On one hand, in the process of converting the three-dimensional mark on the three-dimensional sphere into the two-dimensional mark of the two-dimensional unfolded graph, the display graph to be converted is a three-dimensional sphere graph; the switched display diagram is a two-dimensional expansion diagram; marking the current dimension as a three-dimensional mark; the converted dimension mark is a two-dimensional mark;
in a specific embodiment, the step of obtaining the current dimensional point coordinates of each target point in the to-be-switched display drawing according to the spatial dimensional type of the to-be-switched display drawing includes:
acquiring a target point of the three-dimensional sphere image;
and mapping the target point into a three-dimensional coordinate system according to the hit test to obtain the three-dimensional point coordinate of the target point.
Specifically, if the current display is a three-dimensional sphere (i.e., the display to be switched is a three-dimensional sphere): from the mouse or the touched point (i.e., the target points), the nearest three-dimensional point coordinate P3 can be obtained by hit test, and a three-dimensional tag is generated from P3, and the tagged coordinate and content are recorded in the hash list L3.
It should be noted that, for the above-mentioned nearest three-dimensional point coordinate P3, due to the display diagram currently displayed on the screen, regardless of the three-dimensional or two-dimensional display, the two-dimensional pixel points are rendered substantially, for example, the display diagram to be switched is a three-dimensional sphere diagram, which is a pseudo three-dimensional sphere diagram drawn by using two dimensions. The target point obtained by mouse or touch is two-dimensional in nature; the invention maps two-dimensional points (target points) into a three-dimensional coordinate system rendered by two-dimensional pixel points, and can acquire the nearest three-dimensional coordinate point through related calculation (such as hit test).
The mark coordinate of the three-dimensional mark can refer to a space coordinate system (x, y, z), and the mark content of the three-dimensional mark can refer to content added by a user, and the data is recorded in a corresponding hash list.
In a specific embodiment, the step of converting the current dimension mark according to a preset coordinate conversion rule and a space dimension type of the switched display diagram to obtain a converted dimension mark comprises:
the step of converting the current dimension mark according to a preset coordinate conversion rule and the space dimension type of the switched display diagram comprises the following steps:
acquiring the area width and the area height of the two-dimensional expansion map;
constructing a three-dimensional vector according to the mark coordinates of the three-dimensional mark; obtaining an angle value of a rendering initial coordinate vector of the three-dimensional vector and the two-dimensional expansion map;
and obtaining the marking coordinates of the two-dimensional mark according to the angle value, the area width and the area height.
Specifically, when it is detected that the user clicks the switch button, the radius R of the three-dimensional sphere (i.e., the sphere of the three-dimensional sphere map), the width W of the two-dimensional map (i.e., the two-dimensional expansion map) region, and the height H of the two-dimensional map region may be acquired.
When the current type of the display graph is a three-dimensional sphere and needs to be switched to a two-dimensional map, traversing the Hash list L3, obtaining the coordinate P3 of each item (namely the list item in the Hash list), and constructing a three-dimensional vector Vw(P3.X, P3.Y, 0), the AND vector V (1, 0, 0) is calculated (becauseThe two-dimensional map starts from the angular value a1 of V (1, 0, 0) start rendering, i.e., the rendering start coordinate vector of the two-dimensional expansion map); calculating a ratio ScaleX of A1 to 360 degrees according to A1, namely the ScaleX is the ratio of x where the two-dimensional coordinates are located to W of the two-dimensional map area;
further, vector V is calculated according to P3h(P3.X, P3.Y, P3.Z), and vector Vxy(P3.X, P3.Y, 0) to calculate VhAnd VxyAngle a 2; according to the ratio ScaleY of A2 to 90 degrees, namely ScaleY is the ratio of the Y value of the two-dimensional coordinate to the two-dimensional map area H/2. If the Z value of P3 is greater than 0, then the Y value of the point is greater than H/2, and the calculated two-dimensional coordinates are: p2(scalex W, H/2-ScaleY H/2); if the Z value of P3 is less than 0, then the point Y value is greater than H/2, and the calculated two-dimensional coordinates are: p2(Scale X W, H/2+ Scale Y H/2). The calculated coordinates P2, and the corresponding tag content are added to the hash list L2. (see FIGS. 3 and 4)
It should be noted that, when the center point of the three-dimensional sphere is not located at (0, 0, 0), assuming the center point is C, it is only necessary to shift the vector by V (c.x, c.y, c.z).
FIG. 3 is a schematic diagram illustrating the labeling of target points in a three-dimensional spherical image to be transformed according to the method for displaying a spatial dimension marker of the present invention; FIG. 4 is a schematic diagram illustrating the labeling of target points in a two-dimensional unfolded image after transformation in the method for displaying a spatial dimension label according to the present invention; as shown in fig. 3 and 4, the converted hash list L2 is obtained according to the above steps, the list L2 is traversed, and a label is generated according to the point coordinate P2 in each item and the label content, so as to display each target point.
On the other hand, in the process of converting the two-dimensional marks of the two-dimensional unfolded drawing into the three-dimensional marks on the three-dimensional sphere, the to-be-converted display drawing is a two-dimensional unfolded drawing; the switched display diagram is a three-dimensional sphere diagram; marking the current dimension as a two-dimensional mark; marking the converted dimension as a three-dimensional mark;
specifically, if the currently displayed display diagram to be switched is a two-dimensional map (i.e., a two-dimensional expanded diagram), the added two-dimensional coordinates P2 are obtained according to a mouse or a touched point (i.e., each target point), a two-dimensional marker is generated according to P2, and the marked coordinates and content are recorded in the hash list L2. Preferably, a marked UI class may be generated and its location placed on P2.
In a specific embodiment, the step of converting the current dimension mark according to a preset coordinate conversion rule and a space dimension type of the switched display diagram includes:
acquiring the radius of the three-dimensional spherical image, and the area width and the area height of the two-dimensional unfolded image;
acquiring the angle between the marking coordinate of the three-dimensional mark and each coordinate axis according to the marking coordinate, the area width and the area height of the two-dimensional mark;
and obtaining the mark coordinates of the three-dimensional mark according to the angulation angle and the radius of the three-dimensional sphere graph.
Specifically, when it is detected that the user clicks the switch button, the radius R of the three-dimensional sphere, the width W of the two-dimensional map (i.e., two-dimensional expansion map) region, and the height H of the two-dimensional map region may be obtained.
Traversing the hash list L2, obtaining the coordinate P2 of each item, and calculating a ratio ScaleY ═ (P2.y-H/2)/(H/2), that is, ScaleY is a ratio of a three-dimensional coordinate to 90 degrees, so that an angle AZ ═ ScaleY ═ 90|, between the three-dimensional coordinate and the Z axis is obtained, and then Z ═ R × sin (AZ); the ratio ScaleX is calculated to be p2.x/W,
constructing a vector VT (TX, 0, Z), and calculating a vector VC after the rotation angle of the VT is scaleX 360 degrees by taking the vector (0, 0, 1) (Z axis); if P2.Y is greater than H/2, the three-dimensional coordinate obtained is P3(VC.X, VC.Y, -Z); if P2.Y is less than H/2, the three-dimensional coordinate P3(VC.X, VC.Y, Z) is obtained. The obtained coordinates P3 and the corresponding tag content are added to the hash list L3 (see fig. 5, 6).
Note that when the center point of the three-dimensional sphere is not (0, 0, 0), if the center is C, the correct coordinates can be obtained by simply adding the vector V (c.x, c.y, c.z) to the coordinates obtained in the above step.
FIG. 5 is a schematic diagram of the marking of target points in a two-dimensional unfolded graph to be transformed in the method for displaying a spatial dimension marker of the present invention; FIG. 6 is a schematic diagram illustrating the labeling of target points in a transformed three-dimensional spherical image according to the method for displaying a spatial dimension marker of the present invention; as shown in fig. 5 and 6, the list L3 is traversed, and a tag is generated according to the point coordinate P3 in each item and the tag content, so as to display each target point.
According to the embodiment of the display method of the space dimension mark, the current dimension mark is converted according to a preset coordinate conversion rule and the space dimension type of the display graph after switching, and the converted dimension mark is obtained; according to the converted dimension marks, displaying corresponding target points on the switched display graph, so that the problem of mutual conversion between the three-dimensional marks on the three-dimensional sphere and the two-dimensional marks of the two-dimensional expansion graph can be solved, and synchronous change of the marks with different spatial dimensions can be realized; the invention can greatly simplify the operation of the user, and the user can realize the automatic conversion of the two-dimensional mark and the three-dimensional mark only by adding or modifying the marking content once (namely, in the process of selecting the target point on the display picture to be switched by a mouse or touch).
