[0036] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0037] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs.

[0038] The modifications of "one", "multiple" or "at least one" mentioned in the embodiments of the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0039] As mentioned above, in general, the business logic is completely coupled to the routing module. Every time a new routing rule is added, the code of the routing module must be modified, which causes inconvenience in updating and maintaining the code of the routing module.

[0040] To this end, some embodiments of the present disclosure provide an information display method. Figure 1 , which is a schematic diagram of an application scenario of the information display method provided by the embodiment of the present disclosure. The application scenario includes: a terminal device 101.

[0041] In an embodiment of the present disclosure, the terminal device 101 may run an image processing tool, an animation element generation tool, and a generation tool for adding animation elements to a scene.

[0042] In the embodiments of the present disclosure, the terminal device 101 includes but is not limited to a desktop computer, a mobile phone, a mobile computer, a tablet computer, a media player, a smart wearable device, a personal digital assistant (PDA) or other electronic devices capable of implementing the above functions. The terminal device 101 has a storage unit and an input device, and can create static elements corresponding to animation elements by calling the tools of the storage unit, and can also obtain line information, surface information, etc. of the static elements through the input device to generate static elements.

[0043] After the terminal device 101 generates animation elements or places animation elements into a specific scene to generate a game scene, the generated results can be input into the next terminal device 102, so that downstream operators can further perform subsequent game production based on the animation elements or the scene with added animation elements.

[0044] Based on the above application scenarios and other possible application scenarios, some embodiments of the present disclosure provide an element generation method, which can assist users to quickly generate static elements corresponding to dynamic elements when users need to generate dynamic elements that swing randomly, and provide operational convenience for rendering static elements, thereby improving production efficiency.

[0045] The embodiments of the present disclosure may also be applied to terminal devices having necessary Internet and local area network connections.

[0046] Figure 2 The implementation process of the element generation method of the embodiment of the present disclosure is shown. Figure 2 As shown, the method may include the following steps:

[0047] Step S201: Acquire a first static grid graphic of a target element;

[0048] Step S202: generating a first curve for representing at least one frame of the curved shape of the first static grid graphic;

[0049] Step S203: Binding the first curve to the first static grid graphic according to the bending dynamic information of the target element, so that the bound first static grid graphic bends along with the bending of the first curve;

[0050] Step S204: taking the first static mesh graphic bound to the first curve as the generated target element.

[0051] In one embodiment of the present disclosure, the target element may be an object in a scene to be constructed in a game, animation, movie, etc. For example, the target element may be a tentacle-like creature (i.e., a tentacle creature), a long strip-shaped object, a flat floating object, etc.

[0052] In one embodiment of the present disclosure, the static mesh graphic may be a static mesh object, which may be a polygonal model created in an external tool (such as Maya, image processing software, etc.) and with a texture added. The static mesh graphic may have information such as the shape and surface characteristics corresponding to the target element. The static mesh graphic may be a graphic used to represent the target element, and specifically may be a three-dimensional image, a plane graphic, etc. If the target element is a dynamic element, the static mesh graphic may represent the basic shape of the target element in a static state. For example, if the target element is a tentacle that can swing, the static mesh graphic may be an elongated conical graphic in a static, straight state, representing a straightened static tentacle, such as Figure 3 shown.

[0053] In one embodiment of the present disclosure, the static grid graphic may be composed of lines, planes, or unit graphics, and may include information such as size and coordinates. In a level of the game, multiple copies of a static grid graphic may be placed without a significant drop in machine performance.

[0054] In one embodiment of the present disclosure, the target element is an element with a bendable property, such as a tentacle creature, a vine creature, a flag, a ribbon, etc. The target element can be bent according to some information in the scene in which it exists, such as wind direction, other external forces, changes in the internal force of the target element, etc.

[0055] In an embodiment of the present disclosure, the first curve is a curve that can be expressed by a function expression, and the curvature of the first curve can be changed by using different function parameters.

[0056] In another possible implementation of the present disclosure, the first curve may also be a curve with certain fixed points. The fixed points may be determined by a function expression, and the curve segments between the fixed points may be curve segments determined by other functions.

[0057] In another possible implementation of the present disclosure, the first curve may include a plurality of known points, and the first curve is generated based on the known points and the curve function. In this case, generating the first curve representing the curved shape of the static grid graphic may include generating at least some control points of the first curve, which are the known points.

[0058] In one embodiment of the present disclosure, the aforementioned binding of the first curve to the first static grid graphic according to the bending information of the target element may be binding at least some points of the first curve to the first static grid graphic according to the bending trend of the target element. For example, if the target element is a tentacle-like object, the bending information of the target element may include: bending along the direction in which the tentacle extends, and then the first curve may be bound along the direction of the first static grid graphic corresponding to the extension of the tentacle. For another example, if the target element is a flag, the bending information of the target element may include: bending along the length direction and the width direction of the flag, and then the first curve may be bound along the length direction or the width direction of the first static grid graphic.

[0059] In an embodiment of the present disclosure, the first static mesh graphic after binding bends as the first curve bends, which may include the first static mesh graphic bending as the parameters of the first curve change. As the bending state of the first curve changes in different animation frames, the first static mesh graphic also presents a bending change animation.

[0060] In an embodiment of the present disclosure, the first static mesh graphic bound to the first curve (i.e., the first curve, the first static mesh graphic, and the binding relationship between the first curve and the first static mesh graphic) can be used as the execution result of the element generation method. The first static mesh graphic bends as the parameters of the first curve change, thereby achieving the bending of the first static mesh graphic and achieving the generation of at least one animation state of the target element.

[0061] In the disclosed embodiment, the first curve is used to represent the dynamic bending shape of the target element in at least one frame, and the first curve is bound to the first static grid graphic representing the target element, so that the bending shape of the first static grid graphic can change as the parameters of the first curve change, presenting different bending shapes. Therefore, there is no need to produce different models for different bending shapes of a target element, thereby improving the production efficiency of the dynamic graphics corresponding to the target element.

[0062] In one embodiment of the present disclosure, Figure 4 As shown, the first curve 401 is a spline curve; the first curve generated for representing at least one frame of dynamic bending shape of the first static grid graphic includes:

[0063] Generate a first control point 402 representing the first curve;

[0064] The first control point 402 is used to represent the first curve 401 .

[0065] In an embodiment of the present disclosure, the first curve may be a spline curve, and the spline curve may be a non-uniform rational B-spline curve, which may refer to a curve obtained by giving a set of control points, and the general shape of the curve may be controlled by these control points. The spline curve in the embodiment of the present disclosure is further at least one of an interpolation spline curve and an approximation spline curve, and may be an N-order curve (N≥2).

[0066] In one embodiment of the present disclosure, the control points representing the first curve may be control points of a spline curve corresponding to the first curve. In the spline curve, the control points may be a series of points given in advance. In the embodiment of the present disclosure, the control points may be generated by random generation, segmented capture on the first static grid graph, and the like.

[0067] In an embodiment of the present disclosure, the first control points are used to represent the first curve. After the expression of the first curve or the three-dimensional (or two-dimensional) coordinate generation method of each point on the first curve is predetermined, a plurality of first control points that can be used to fit the first curve are generated, and the first curve is considered to be generated. Alternatively, after the control points are generated, the first curve can be generated by using a spline curve generation method.

[0068] In one embodiment of the present disclosure, the spline curve can be a cubic spline curve, and a piecewise cubic spline interpolation can be implemented in the Vertex Shader (vertex shading engine) to express the curvature of the static mesh of the target element such as the tentacle creature. In a specific implementation method, a series of control points of the cubic spline curve are first determined, and between every two adjacent control points, the positions of each fixed point between the two adjacent control points are determined according to the positions of the two adjacent control points and the tangent direction of each vertex. Among them, the tangent direction of each vertex can be determined based on the external force information that may affect the target element such as the tentacle creature, such as the wind direction in the target scene.

[0069] In this embodiment, the first curve adopts a spline curve, so as to improve the swinging and floating effects of the target element after it is generated.

[0070] In an embodiment of the present disclosure, the binding of the first curve with the first static grid graphic according to the bending dynamic information of the target element includes:

[0071] Bind the vertices of the first static mesh graphic to the corresponding first control points.

[0072] In this embodiment, the points of the first static grid graphic representing the target element are bound to the first control points representing the first curve, so that the first static grid can bend along with the bending of the first curve, thereby achieving the dynamic effect of swinging and bending of the target element.

[0073] In one embodiment of the present disclosure, the element generation method further includes:

[0074] In response to the generation instruction, an instance of the target element is generated according to the expression of the first control point and the first curve;

[0075] According to the acquired orientation information of the target element, the positions of all vertices of the first static mesh graphic are determined using the above example.

[0076] Through the above embodiment, the target element is placed in the game scene, so that dynamically changeable tentacles can be generated in the game scene.

[0077] In one embodiment of the present disclosure, the element generation method further includes:

[0078] When the generated target element is placed in the target scene, detect whether there is a collision between the target element and other elements;

[0079] In the case of collision, axis adjustment information for the target element is generated according to the preset element spacing;

[0080] Adjust the information according to the axis to obtain the orientation information.

[0081] In one embodiment of the present disclosure, when the element generation method is applied to the generation of a tentacle creature in a game, a scene blueprint may be provided first to represent a tentacle creature. Place the tentacle creature into the level, adjust the position, size, and direction (the basic growth direction of the tentacle) of the tentacle creature, and click "Re-randomly Generate" to automatically generate spline points randomly. During generation, collision detection is performed on the scene to ensure that the position of each spline point (control point) is legal, thereby achieving wall climbing and window penetration. It is assumed that the spline point position P(0) of the 0th (i.e., the root of the tentacle) to the spline point with the maximum number of spline points is legal one by one, and the position of the next spline point (i) of the previous spline point (i-1) is randomly generated according to the position of the previous spline point, the spline point spacing, the direction, and the maximum random cone angle (Cone Angle). From the position of the previous spline point to the position of the next spline point, a Line Trace is performed on the scene collision. If the result is true, it means that there is a collision between the target elements interspersed between the spline points. Calculate a rotation angle and rotation axis based on the position of the previous spline point, the position of the next spline point, the wall normal, and the allowed distance from the wall (Off Wall Distance). Recalculate the position of the next spline point based on the direction of the rotation of the vector [position of the next spline point, position of the previous spline point] to adjust the position of the spline point. Record the last spline point affected by the scene collision as the animatable starting spline point. The aforementioned maximum random cone angle can be a cone angle randomly generated by the tentacle within the allowed swing range.

[0082] In one embodiment of the present disclosure, the vertex positions determined according to the orientation information may be the positions of all vertices of the first static mesh graph when the target element is in a bent and stationary state. After binding the first curve 701, the first static mesh graph 702 in a stationary state may refer to Figure 7 shown.

[0083] In one embodiment of the present disclosure, an element generation method is used to generate tentacle creatures (tentacle creatures) in a game level. After the game level is edited, all tentacle creatures in the target scene are converted into corresponding instanced static meshes, each tentacle creature corresponds to an instance, and the position and tangent direction of each spline point become per-instance custom data. According to the per-instance custom data, the vertex position of each target element static mesh graph can be obtained, and the corresponding target element static mesh graph is composed of the positions of all vertices.

[0084] In the disclosed embodiment, the static mesh graphics can be rendered through the instance corresponding to the target element to achieve the color, texture and other effects required by the game. When using the instance for real-time rendering, the Vertex Shader reads the per-instance custom data to obtain the position and tangent direction of each spline point, and calculates the offset value of each vertex of the static mesh graphics through the above-mentioned piecewise cubic spline curve interpolation function to achieve the bending of each tentacle creature as the target element.

[0085] In this embodiment, generating an instance of the target element according to the expression of the first control point and the first curve may include instantiating the first static mesh and the first curve bound thereto. The instance generated by the instantiation process can render each frame of the animation screen in which the first static mesh changes along with the first curve.

[0086] In one embodiment of the present disclosure, the element generation method further includes:

[0087] When the generated element is placed in the target scene, in response to an axis adjustment operation on the target element, acquiring axis adjustment information on the element;

[0088] The above-mentioned orientation information is obtained according to the above-mentioned axis adjustment information.

[0089] In the embodiment of the present disclosure, the generated element includes a first static grid figure, a first curve and a binding relationship between the two. The element generated by the method of the embodiment of the present disclosure can be placed in a game level. After the generated target element is placed in the game level, the axis of the corresponding target element can be obtained, and the axis can be substantially consistent with the extension direction of the first static grid figure.

[0090] The direction of the first static grid graphic can be adjusted by adjusting the axis, that is, the direction of the target element can be adjusted. After the direction is adjusted, the first static grid graphic can generate effects such as interlacing and surrounding according to objects such as buildings in the scene.

[0091] In this embodiment, when the generated element is placed in the target scene, the orientation of the target element can be adjusted, so that different target elements can be generated as needed in scenes such as game levels.

[0092] In one embodiment of the present disclosure, the element generation method further includes:

[0093] In response to the selection instruction, determining at least one sub-element generation point on the target element; the generation point is a vertex on the first static mesh graphic;

[0094] generating a sub-element second curve and a second sub-element static mesh graphic related to the sub-element according to the generating point;

[0095] Bind the sub-element curve to the above sub-element static mesh graphic;

[0096] Set the sub-element static mesh graphics of the bound sub-element curve as the sub-element of the above target element;

[0097] The sub-element is bound to the element, so that the curve corresponding to the target element includes the sub-element curve, and the vertices of the target element include the vertices of the static mesh of the sub-element.

[0098] In one embodiment of the present disclosure, the generation point may be one of the vertices of the first static mesh graphic. Any point on the first static mesh graphic may be selected as the generation point of the sub-element, and the sub-element of the target element may be generated in a manner similar to the process of binding the first static mesh and the first curve. In the case where the target element is a tentacle creature, the sub-element may be a sub-tentacle; in the case where the target element is a vine creature, the sub-element may be a sub-branch of the vine creature.

[0099] In the case of having a sub-element, the curve corresponding to the target element may include a sub-element curve of the sub-element and a first curve corresponding to the first static mesh graphic.

[0100] The type of the sub-element curve can be the same as or different from the first curve.

[0101] When the branches of the child elements, i.e. the target elements, are generated, the position of their roots on the trunk and their size relative to the trunk are considered; scene collisions are also considered.

[0102] In this embodiment, a target element and sub-elements of the target element can be generated in a similar manner, thereby enriching the form of the target element.

[0103] In one embodiment of the present disclosure, the first curve is any one of a Bezier curve and a Nyquist curve; and the target element is a tentacle creature.

[0104] In the embodiment of the present disclosure, if the first curve is not a spline curve, the type of the first curve may be a Bezier curve or a Nyquist curve. The tentacle creature in the embodiment of the present disclosure may be an animal tentacle or a plant tentacle, and the tentacle creature may be placed in a scene, and the position, size, and orientation may be adjusted according to the surrounding scene, so as to make it look like it is clinging to a building while avoiding mistakes (the tentacles may intersect with the building when swinging).

[0105] In one embodiment of the present disclosure, a rendering method is provided, including:

[0106] Obtain a target element to be rendered; the target element is generated by the element generation method provided by any embodiment of the present disclosure;

[0107] Renders the target element.

[0108] In one embodiment of the present disclosure, Figure 5 As shown, the element generation method uses the above example to perform the following steps for each target animation frame of the above target element:

[0109] Step S501: obtaining the floating direction information of the target element;

[0110] Step S502: acquiring parameters of the curve corresponding to the target element according to the floating direction information; the curve corresponding to the element includes the first curve;

[0111] Step S503: determining the positions of the vertices of the first static mesh graphic according to the above parameters;

[0112] Step S504: Determine the shape of the target element according to the position of the vertex.

[0113] In the disclosed embodiment, the fluttering direction information can be determined based on the background information of the target scene where the target element is located. For example, the target element can flutter with the wind direction in the target scene. The instance corresponding to the target element can obtain the fluttering direction information generated by external factors or the movement of the target element itself in the target scene, and adjust the bending state of each frame of the target element animation according to the fluttering direction information to present a more realistic dynamic effect.

[0114] In one embodiment of the present disclosure, the floating direction information may be information for causing the target element to float in a certain direction. For example, if the wind blows toward the south, the target element may float toward the south.

[0115] In the case where the target element is a tentacle creature, the animation of the tentacle creature floating is realized by updating the position of the spline point in each animation frame. The updating process may include: obtaining the position of each spline point, the tangent direction of the spline point, and other information in the target scene that affects the floating direction of the target element (such as wind direction, wind speed, wind strength, etc.) instance by instance through the Tick function (periodic scheduling function) of each animation frame, and calculating the rotation angle and rotation axis of each spline point according to the position of each spline point, the tangent direction of the spline point, and other information that affects the floating direction of the target element, and the calculation order is to calculate one by one from the spline point at the root of each tentacle creature to the spline point at the top.

[0116] In the disclosed embodiment, during the floating of the element, parameter information of the first curve is obtained through examples frame by frame, and the bending shape of the first curve is adjusted according to the parameter information determined frame by frame, and then the bending shape of the first static grid graphic is adjusted to achieve different bending states of the target element.

[0117] In the disclosed embodiment, the tentacle creature can be as follows Figure 6As shown. In general, the models and animations of such tentacle creatures in the game level are manually made by operators. According to the static mesh graphics, the skeleton of the tentacle creature is made, and the weights of each vertex of the static mesh model are obtained to obtain the skeleton model. Then the operator makes the idle animation of the skeleton model (animation when the character is idle) to show the fluttering of the tentacle creature. If the tentacle creature is made manually, there are the following disadvantages: the form is single, a skeleton model has only one form, if n forms are required, n models must be made, resulting in n times the workload and resources; the rendering efficiency is low, when multiple tentacles are displayed on the screen at the same time, multiple drawcalls are required (the process of the controller calling the image programming interface to realize the rendering operation). For example, if there are 3 tentacle creatures in the same scene, 3 drawcalls are required to render; the swing direction and amplitude of the tentacle creature are preset during the animation production, and cannot reflect the dynamic factors of the scene as a whole, such as the wind field (direction, wind speed, wind strength, etc.).

[0118] Through the disclosed embodiments, multiple target elements such as bent tentacle creatures with different shapes and different numbers of branches can be quickly generated; target elements such as tentacle creatures can automatically climb walls and pass through windows; through instantiated target elements, all target elements in the target scene can be efficiently rendered, and only one drawcall is required regardless of the number of target elements such as tentacle creatures in the entire scene. At the same time, the disclosed embodiments can express the movement and flutter parameters of target elements such as the dynamic wind field of the entire target scene through programmed spline point animation.

[0119] The present disclosure also provides an element generation device, such as Figure 8 As shown, including:

[0120] A static grid graphic generation module 801 is used to obtain a first static grid graphic of a target element;

[0121] A curve generating module 802, used for generating a first curve for representing a curved shape of at least one frame of the first static grid graphic;

[0122] A binding module 803 is used to bind the first curve to the first static grid graphic according to the dynamic bending information of the target element, so that the bound first static grid graphic bends along with the bending of the first curve;

[0123] The element module 804 is used to use the first static mesh graphic bound to the first curve as a generated target element.

[0124] In one implementation, the first curve is a spline curve; and the curve generation module includes:
