[0045] The communication module 120 is used to establish a communication connection between the electronic device and other communication terminals through a network, and to send and receive data through the network.
[0046] It should be understood that Figure 1 The structure shown is only a schematic diagram of the structure of the electronic device. The electronic device may also include Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown. Figure 1 Each component shown in the figure can be implemented by hardware, software or a combination thereof.
[0047] Next, the above Figure 1 The electronic device in the embodiment is the execution body, and the decal method provided in the embodiment of the present application is exemplarily introduced in combination with the flow chart.
[0048] Specifically, Figure 2 A schematic diagram of a process for the decal method provided in the embodiment of the present application is shown in FIG. Figure 2 , the method comprising:
[0049] Step S20, obtaining a decal model, and when it is determined that the decal model is to be decaled, calculating the normal coordinates of the decal target point in the decal model.
[0050] Optionally, the decal model may be a decal model input by a user, or may be a decal model calculated by an electronic device.
[0051] For example, the decal model may be a graffiti model created by a user when graffiti is applied to a wall, or may be a bullet hole model calculated by an electronic device when a user performs a shooting operation in a game, and so on.
[0052] Optionally, the decal target point refers to the surface position of the model to be decaled to which the decal needs to be applied, that is, the contact point or center point between the decal model and the model to be decaled.
[0053] Optionally, the electronic device may calculate the normal coordinates of the decal target point by the three-dimensional coordinates of the decal target point in the decal model. It is understandable that the normal coordinates are also three-dimensional coordinates.
[0054] In one example, if HLSL (High-Level Shading Language) is used, cross(ddy, ddx) may be used to calculate the normal coordinates of the decal target point in the decal model.
[0055] Among them, ddy represents the y-axis coordinate of the decal target point in the model space of the decal model, and ddx represents the x-axis coordinate of the decal target point in the model space of the decal model.
[0056] Step S21 , performing three-dimensional texture sampling on the decal model to obtain a plurality of texture colors, and calculating a target color according to the normal coordinates and the plurality of texture colors.
[0057] Optionally, the electronic device may perform three-dimensional texture sampling on the decal model to obtain texture colors corresponding to each main plane of the three-dimensional coordinates of the decal model.
[0058] Step S22, rendering the texture of the decal model onto the decal target point according to the target color.
[0059] It can be understood that the electronic device can implement decaling for the model to be decaled by rendering the texture of the decal model onto the decal target point according to the target color.
[0060] According to the decal method provided in the embodiment of the present application, the electronic device can calculate the target color that should be used for decal according to the normal coordinates of the decal target point in the decal model and the multiple texture colors obtained after three-dimensional texture sampling of the decal model, and then perform decals according to the target color. Since the normal of the decal target point can represent the surface slope of the object to be decaled, the decal model can be decaled in combination with the height information, thereby solving the texture stretching problem that may exist when decals are performed at the position where multiple planes intersect, thereby improving the decal effect.
[0061] Optionally, in order to prevent the decal from appearing in inappropriate positions or having a penetration effect, such as appearing inside the object to be decaled, or visually appearing to penetrate the model surface, the electronic device can first determine whether the decal target point is located in the model space of the decal model after acquiring the decal model.
[0062] Specifically, the electronic device may determine a coordinate vector corresponding to a decal target point according to the position coordinates of the decal model and a preset depth map, and determine whether the decal target point is located in the model space of the decal model according to the coordinate vector.
[0063] Optionally, the depth map refers to the depth map of the current scene. For example, if decals need to be applied to a game scene, the depth map refers to the depth map of the current game scene.
[0064] Optionally, the depth map records depth information of each pixel.
[0065] Optionally, since the position coordinates of the decal model can represent the position coordinates corresponding to the decal target point, a coordinate vector corresponding to the decal target point can be constructed according to the position coordinates of the decal model and the depth map.
[0066] In this embodiment, if the decal target point is located in the model space of the decal model, the electronic device may determine to apply the decal to the decal model.
[0067] Optionally, if the decal target point is located in the model space of the decal model, it can be ensured that the decal model can be correctly positioned and thus rendered on the model surface, otherwise, the decal error problem may occur. Therefore, the electronic device can decal the decal model when it is determined that the decal target point is located in the model space of the decal model, and give up decaling the decal model when the decal target point is not located in the model space of the decal model, thereby avoiding the decal error problem.
[0068] In a possible implementation manner, the position coordinates of the decal model may be two-dimensional coordinates.
[0069] In this embodiment, the two-dimensional coordinate refers to a two-dimensional coordinate in an NDC (Normalized Device Coordinates) space.
[0070] Optionally, the electronic device may first obtain the two-dimensional coordinates of the decal model in the screen space, and then convert the two-dimensional coordinates into the NDC space, thereby obtaining the two-dimensional coordinates of the decal model in the NDC space.
[0071] Optionally, the coordinate vector corresponding to the decal target point may be a four-dimensional coordinate vector.
[0072] In this embodiment, the electronic device can determine the depth value corresponding to the decal target point based on the two-dimensional coordinates of the decal model and a preset depth map, and thus determine the four-dimensional coordinate vector corresponding to the decal target point based on the two-dimensional coordinates of the decal model, the depth value of the decal target point and a preset perspective value.
[0073] Optionally, since the position coordinates of the decal model can represent the position coordinates corresponding to the decal target point, the electronic device can determine the depth value corresponding to the decal target point based on the two-dimensional coordinates of the decal model and the depth map.
[0074] In a possible implementation, the preset perspective value may be 1.0f.
[0075] Optionally, the electronic device may construct a four-dimensional coordinate vector (x, y, z, w) corresponding to the decal target point according to the two-dimensional coordinates x, y, depth value z and preset perspective value w of the decal model.
[0076] It can be understood that the four-dimensional coordinate vector constructed according to the two-dimensional coordinates of the decal model, the depth value of the decal target point and the preset perspective value is the coordinate vector of the decal target point in the NDC space.
[0077] Next, a possible implementation method is given for determining whether the decal target point is located in the model space of the decal model based on the coordinate vector.
[0078] Specifically, the electronic device may multiply the four-dimensional coordinate vector by the inverse matrix of the MVP (Model-View-Projection Matrix) of the decal model to obtain the target coordinate vector of the decal target point.
[0079] It can be understood that the target coordinate vector is a four-dimensional coordinate vector of the decal target point in the model space of the decal model.
[0080] Optionally, the electronic device may convert the four-dimensional coordinate vector in the NDC space into a four-dimensional coordinate vector in the model space of the decal model by multiplying the four-dimensional coordinate vector by the MVP inverse matrix of the decal model.
[0081] In this embodiment, if the x value, y value, and z value of the target coordinate vector meet preset conditions, it can be determined that the decal target point is located in the model space of the decal model.
[0082] Optionally, the preset condition can be determined according to the model characteristics of the model to be decaled.
[0083] It can be understood that, since the model features of different models to be decaled may be different, different preset conditions may be set for the models to be decaled with different model features.
[0084] In a possible implementation, if the model to be decaled is a cube, the preset condition may be that the absolute values of the x, y and z components of the target coordinate vector do not exceed half of the side length of the model to be decaled.
[0085] For example, if the model to be decaled is a cube with a side length of 1, the preset condition may be that the absolute values of the x-value, y-value, and z-value components of the target coordinate vector do not exceed 0.5.
[0086] Next, a possible implementation method is provided for how to perform three-dimensional texture sampling on the decal model, obtain multiple texture colors, and calculate the target color based on the normal coordinates and multiple texture colors.
[0087] Specifically, in Figure 2 On the basis of Figure 3 For another schematic diagram of the decal method provided in the embodiment of the present application, please refer to Figure 3 , the above step S21 can be implemented by the following steps:
[0088] Step S21 - 1 , performing three-dimensional texture sampling on the decal model to obtain a first texture color of the decal model in the xz plane, a second texture color in the zy plane, and a third texture color in the xy plane.
[0089] Optionally, the electronic device may perform three-dimensional texture sampling on the decal model according to an xz plane, a zy plane, and an xy plane, respectively, so as to obtain a first texture color, a second texture color, and a third texture color.
[0090] Step S21 - 2 , calculating the target color according to the normal coordinates, the first texture color, the second texture color, the third texture color and a preset formula.
[0091] Optionally, the preset formula may be used to perform weighted mixing on the first texture color, the second texture color, and the third texture color according to the normal coordinates, thereby obtaining a target color.
[0092] In a possible implementation, the preset formula is represented as follows:
[0093]
[0094] Among them, C represents the target color, C 1 Characterize the first texture color, C 2 Characterize the second texture color, C 3 Characterizes the third texture color, n x Characterizes the normal x-axis coordinate, n y Represents the normal y-axis coordinate, n z Represents the normal z-axis coordinate.
