[0066] S1: Determine the display grid based on the selected spline information and the length information perpendicular to the spline direction.

[0067] The spline information includes spline length, spline curvature, spline vertex coordinates, and coordinate transformation relationship between the virtual space coordinate system and the uv coordinate system.

[0068] Multiple splines can be displayed to users in a virtual space, and users can select the spline that meets their personalized needs through the spline selection button in the virtual space.

[0069] Figure 2 This is a schematic diagram illustrating a mesh in a virtual space coordinate system, as shown in one example of this disclosure. Figure 2 As shown, the user selects spline S1. The spline information for S1 includes its coordinate length and curvature in virtual space, the coordinates of vertex A1 and vertex An, and the coordinate transformation relationship between the virtual space coordinate system and the uv coordinate system. In this example, the length information perpendicular to the spline direction is the distance Depth between spline S1 and spline S2.

[0070] Spline S2 can be obtained by translating spline S1 by Depth in a direction perpendicular to the spline, and then a display mesh can be formed based on spline S1 and spline S2. The vertices of the display mesh include A1, A2, An, and An+1.

[0071] It should be noted that the selected spline can also be spline S2, and spline S1 can be obtained by translating spline S2 in a direction perpendicular to the spline direction by Depth.

[0072] S2: Get the set of uv coordinates of the information to be displayed in the uv coordinate system.

[0073] The to-be-displayed information can include a to-be-displayed image provided by a user, and in this case, a set of uv coordinates of all pixel points of the to-be-displayed image in the uv coordinate system are acquired.

[0074] S3: determining a set of virtual coordinates of the to-be-displayed information in the virtual space coordinate system based on the set of uv coordinates and the coordinate conversion relationship.

[0075] For any uv coordinate in the set of uv coordinates, a virtual coordinate in the virtual space coordinate system is converted through the coordinate conversion relationship.

[0076] All virtual coordinates corresponding to the uv coordinates in the set of uv coordinates can be obtained through the above manner. The set of virtual coordinates of the to-be-displayed information in the virtual space coordinate system is composed of all virtual coordinates corresponding to the uv coordinates.

[0077] S4: rendering the to-be-displayed information in the virtual space based on the set of virtual coordinates and the display grid to obtain a rendered image.

[0078] The display grid is placed in the virtual space. An area of the display grid in the virtual space is set as a rendering area. A set of rendering coordinates in the rendering area is determined according to the set of virtual coordinates, and each coordinate point in the set of rendering coordinates is rendered based on a given rendering color to obtain the rendered image.

[0079] Figure 3 A schematic diagram of the rendered image in one example of the present disclosure is shown in FIG. 1. As shown in FIG. 1, the rendering area is an area composed of a vertex A1, a vertex A2, a vertex An, and a vertex An+1. The to-be-displayed information is rendered in the rendering area to obtain a rendered image with a curved surface display effect. Figure 3

[0080] In the present embodiment, after the set of spline lines is provided to the user, the display grid can be generated according to the selected spline line information and the length information perpendicular to the direction of the spline line, the set of virtual coordinates of the to-be-displayed information in the virtual space coordinate system can be obtained through the coordinate conversion relationship, and the rendered image meeting the individual needs of the user can be obtained by rendering the to-be-displayed information according to the set of virtual coordinates and the display grid.

[0081] In one embodiment of the present disclosure, step S1 can include:

[0082] S1-1: generating a first spline line in the virtual space coordinate system based on the spline line vertex coordinates, the spline line length, and the spline line curvature. The first spline line is one side of the display grid.

[0083] Please refer to Figure 2 ​The first spline line can be one of the spline line S1 and the spline line S2.

[0084] S1-2: translating the first spline line by a target length in a direction perpendicular to the spline line direction to obtain a second spline line. The length information in the direction perpendicular to the spline line direction includes the target length, and the second spline line is a pair of edges corresponding to the first spline line in the display grid.

[0085] Please refer to Figure 2 The target length can be the height of the Depth. When the first spline line is the spline line S1, the second spline line is the spline line S2; when the first spline line is the spline line S2, the second spline line is the spline line S1.

[0086] S1-3: determining the display grid based on the first spline line and the second spline line.

[0087] Please refer to Figure 2 The display grid can be composed of the spline line S1, the spline line S2, an edge formed by the vertex A1 and the vertex A2, and an edge formed by the vertex An and the vertex An+1.

[0088] In this embodiment, the first spline line can be generated according to the spline line vertex coordinates, the spline line length and the spline line curvature, and the second spline line can be obtained by translating the first spline line. By connecting the vertices corresponding to the first spline line and the second spline line, a display network meeting the user's demand can be quickly generated, which helps to generate a display screen meeting the user's individual demand based on the display network, and further helps to display an image meeting the user's individual demand in the display screen.

[0089] In one embodiment of the present disclosure, the spline line information further includes a spline line direction. The spline line direction is one of a first preset direction and a second preset direction. Accordingly, step S1-2 can include:

[0090] S1-2-1: in response to the spline line direction being the first preset direction, translating the first spline line by the target length in a first coordinate axis direction of the virtual space coordinate system to obtain the second spline line.

[0091] Please refer to Figure 2 The spline line directions of the spline line S1 and the spline line S2 are the first preset direction, for example, the horizontal direction. The first coordinate axis direction can be a coordinate axis direction parallel to the Depth direction.

[0092] S1-2-2: in response to the spline line direction being the second preset direction, translating the first spline line by the target length in a second coordinate axis direction of the virtual space coordinate system to obtain the second spline line.

[0093] Please refer to Figure 2 When the spline S1 is rotated 90 degrees in the vertical direction with the vertex A1 as the rotation axis, the direction of the spline S1 at this time is the second preset direction, for example, the vertical direction. The second coordinate axis direction Figure 2 The horizontal and left-right direction coordinate axis direction is shown.

[0094] In this embodiment, the first spline can be translated in the corresponding direction to obtain the second spline according to different spline directions, which is helpful to quickly determine the display grid, and further helps to generate a display screen that meets the user's individual needs based on the display network, and further helps to display an image that meets the user's individual needs in the display screen.

[0095] In an embodiment of the present disclosure, step S1-3 can include:

[0096] S1-3-1: determining a plurality of triangular facets based on the first spline and the second spline.

[0097] S1-3-2: determining the display grid based on the plurality of triangular facets.

[0098] As Figure 2 shown, points A1 and A3 can be selected in the spline S2 first, and point S2 is selected in the spline S1, and a triangular facet is formed by points A1, S2 and A3, then points A2 and A4 are selected in the spline S1, and point S3 is selected in the spline S2, and a triangular facet is formed by points A2, S3 and A4, and so on. One or two points are selected in the spline S2 and the spline S1 alternately to form a triangular facet, and finally a display network is formed.

[0099] In this embodiment, points are selected alternately on the first spline and the second spline to form a plurality of triangular facets, and further a display grid that meets the user's individual needs can be formed by the plurality of triangular facets, and further helps to generate a display screen that meets the user's individual needs based on the display network, and further helps to display an image that meets the user's individual needs in the display screen.

[0100] In an embodiment of the present disclosure, step S4 can include:

[0101] S4-1: determining a display screen in the virtual space based on the display grid.

[0102] According to the relative position relationship between all points in the display network and the virtual space coordinates of at least one point in the virtual space, a set of virtual space coordinates of all points in the display grid in the virtual space can be determined. The display screen in the virtual space is determined according to the virtual space coordinates.

[0103] S4-2: Based on the set of virtual coordinates, the display position of the to-be-displayed information in the display screen is determined.

[0104] According to the virtual space coordinates of the display screen, it is determined whether the coordinate point corresponding to each virtual space coordinate in the set of virtual coordinates is located in the display screen. If the coordinate point is located in the display screen, the virtual space coordinates of the coordinate point are retained. If the coordinate point is located outside the display screen, the virtual space coordinates of the coordinate point are deleted from the set of virtual coordinates.

[0105] According to the virtual space coordinates of the display screen and the virtual space coordinates of the coordinate points finally retained in the set of virtual coordinates, the display position of the to-be-displayed information in the display screen is determined.

[0106] S4-3: Based on the rendering color of the to-be-displayed information, the to-be-displayed information is rendered in the display position.

[0107] According to the rendering color required for rendering the to-be-displayed information, the to-be-displayed information is rendered in the display position.

[0108] In this embodiment, according to the virtual space coordinates of the display screen, it is determined whether the coordinate point corresponding to each virtual space coordinate in the set of virtual coordinates is located in the display screen. The coordinate points located outside the display screen are deleted, and only the coordinate points located in the display screen are subjected to color rendering, which can improve the accuracy of the display position of the screen.

[0109] In an embodiment of the present disclosure, step S3 can include: determining the set of virtual coordinates based on the set of uv coordinates, the coordinate conversion relationship, and first display adjustment information.

[0110] The first display adjustment information includes at least one of display position adjustment information and display scale adjustment information.

[0111] After obtaining the set of uv coordinates and the coordinate conversion relationship, the display position and the image aspect ratio of the to-be-displayed information in the display screen can be adjusted according to user needs, further improving the display effect of user individual needs.

[0112] In an embodiment of the present disclosure, after step S4, it can further include:

[0113] S5: adjusting the rendering image based on the second display adjustment information. The second display adjustment information includes at least one of display position adjustment information, display proportion adjustment information, and display color adjustment information.

[0114] In this embodiment, when the user is not satisfied with the display effect of the rendering image, the display position of the rendering image in the display screen can be adjusted, the aspect ratio of the rendering image can be adjusted, and the display color of the rendering image can be adjusted, thereby further improving the display effect of the user's individual needs.
