[0056] Currently, only direct lighting is used to draw scenes in games, which can no longer meet the requirements of players for game images. Direct lighting refers to the light source directly hitting the object, which reflects the light into the human eye. Now the game engine will consider indirect lighting while calculating direct lighting, thereby achieving global illumination and obtaining a more realistic effect.

[0057] At present, the construction of the three-dimensional sense of the game screen in the game engine is mainly achieved through the post-processing screen space ambient occlusion technology. The parameters for implementing screen space ambient occlusion in the NeoX engine include: intensity, radius, offset, sharpness, and screen space ambient occlusion type. Screen space ambient occlusion is built based on the three-dimensional sense of the entire game screen. When the screen space ambient occlusion effect suitable for the game scene is used, the effect on the model is not obvious; if the parameters of the screen space ambient occlusion are adjusted according to the effect of the model, the ideal occlusion effect cannot be achieved for the game scene.

[0058] Based on one or more of the above problems, this exemplary embodiment first provides an ambient light shielding implementation method, which can be run on a device terminal, which can include a desktop computer, a portable computer, a smart phone, a tablet computer, etc. Of course, those skilled in the art can also run the method of the present invention on other platforms as required, and this exemplary embodiment does not specifically limit this. Figure 1 As shown, the ambient light occlusion implementation method may include the following steps:

[0059] Step S110: Obtain a target model and a bounding box range of the target model, and determine a relative position of a fragment of the target model with respect to the bounding box range;

[0060] Step S120. Based on the relative position of the fragment with respect to the bounding box range, the height variation range of the fragment is obtained, and the height variation range of the fragment is input into the occlusion channel, and the overall ambient light occlusion of the target model is achieved through the occlusion channel;

[0061] Step S130: Generate an occlusion map of the target model, perform grayscale processing on the occlusion map to obtain a target occlusion map, and implement detailed ambient light occlusion of the target model through the target occlusion map.

[0062] The above-mentioned ambient light occlusion implementation method obtains the target model and the bounding box range of the target model, determines the relative position of the fragment of the target model with respect to the bounding box range; obtains the height variation range of the fragment based on the relative position of the fragment with respect to the bounding box range, inputs the height variation range of the fragment into the occlusion channel, and implements the overall ambient light occlusion of the target model through the occlusion channel; generates an occlusion map of the target model, performs grayscale processing on the occlusion map, obtains the target occlusion map, and implements the detailed ambient light occlusion of the target model through the target occlusion map. On the one hand, the relative position of the fragment of the target model with respect to the bounding box range is first calculated. , the height variation range of the fragment is obtained, and the height variation range of the fragment is input into the occlusion channel. The overall ambient light occlusion effect of the target model is adjusted through the occlusion channel, which solves the problem that the occlusion effect of the model in the picture cannot be adjusted separately in the related technology, and improves the efficiency of realizing the overall ambient light occlusion effect of the model; on the other hand, after realizing the overall ambient light occlusion effect of the target model, the occlusion map of the target model is generated, and the occlusion map is processed to obtain the target occlusion map. The target occlusion map is used to realize the detail ambient light occlusion effect of the target model, and the three-dimensional sense of the target model is further enhanced.

[0063] Hereinafter, each step involved in the method for implementing ambient light occlusion according to the exemplary embodiment of the present disclosure is explained and illustrated in detail.

[0064] In step S110, a target model and a bounding box range of the target model are obtained, and a relative position of a fragment of the target model with respect to the bounding box range is determined.

[0065] Among them, the bounding box is an algorithm for solving the optimal bounding space of a discrete point set. The basic idea is to use a geometric body (called a bounding box) with a slightly larger volume and simpler characteristics to approximately replace complex geometric objects. In this example embodiment, the bounding box of the target model can be calculated by a bounding box algorithm. The bounding box algorithm can be an aabb (axis-aligned bounding box, axis-aligned rectangular bounding box) bounding box, a bounding sphere, or an oriented bounding box obb (oriented bounding box, oriented bounding box). In this example embodiment, the bounding box algorithm is not specifically limited. Those skilled in the art can select the corresponding bounding box algorithm to generate a bounding box as needed.

[0066] In this example embodiment, after the target model and the bounding box of the target model are obtained, the range of the bounding box of the target model can be determined. After the range of the bounding box of the target model is determined, the coordinates of the target model and the bounding box range of the target model can be used to calculate the bounding box range of the target model. Figure 2 The bounding box of the target model is shown. Figure 2 Taking the bounding box of the target model shown in FIG. 1 as an example, the bounding box range of the target model may be the three-dimensional coordinate range of the bounding box of the target model. When obtaining the range of the bounding box of the target model, Figure 2 The point in the lower left corner is used as the origin (0,0,0) to establish a three-dimensional coordinate system, and then obtain the range of the bounding box of the target model. The relative position of the fragment of the target model relative to the bounding box range of the target model is determined according to the range of the bounding box of the target model. Figure 3 As shown, determining the relative position of the fragment of the target model with respect to the bounding box range may include step S310 and step S320:

[0067] Step S310. Determine the world coordinates of the target model, and obtain the object space coordinates of the target model through the world coordinates of the target model;

[0068] Step S320: Divide the object space coordinates of the target model by the bounding box range of the target model to obtain the relative position of the fragment of the target model with respect to the bounding box.

[0069] In the following, step S310 and step S320 will be further explained and illustrated. Specifically, first, the target model is obtained, and the world coordinates of the target model are determined. The world coordinates are the objective space that defines the position of the physical world. They are the three-dimensional space coordinates of the real world and are three-dimensional coordinate systems. After obtaining the world coordinates of the target model, the world coordinates of the target model can be multiplied by the inverse transformation matrix to obtain the object space coordinates of the target model, wherein the object space coordinates of the target model are the coordinate system of the target model. After obtaining the object space coordinates of the target model, the object space coordinates of the target model can be divided by the bounding box range of the target model, that is, the object space coordinates of the target model can be divided by the three-dimensional coordinates of the bounding box of the target model to obtain the relative position of the fragment of the target model relative to the bounding box. Among them, the dimension of the value of the relative position of the fragment of the target model relative to the bounding box is the same as the dimension of the coordinate value of the bounding box of the target model or the dimension of the object space coordinates of the target model, and the range of the value of the relative position of the fragment of the target model relative to the bounding box is [0,1]. The fragment of the target model may include the depth value, normal and texture coordinates of the model midpoint. After the fragment passes the test, the normal, texture coordinates and other unnecessary information are discarded to become a pixel. The pixel is the smallest unit of the image presented on the screen containing R (Red), G (Green), B (Blue) and A (Alpha) values.

[0070] In step S120, based on the relative position of the fragment with respect to the bounding box range, the height variation range of the fragment is obtained, and the height variation range of the fragment is input into the occlusion channel, and the overall ambient light occlusion of the target model is achieved through the occlusion channel.

[0071] In this exemplary embodiment, after the relative position of the fragment of the target model relative to the bounding box range of the target model is obtained, the height variation range of the fragment of the target model can be obtained according to the relative position of the fragment of the target model relative to the bounding box range of the target model. Figure 4 As shown, based on the relative position of the fragment relative to the bounding box range, obtaining the height variation range of the fragment may include step S410 and step S420:

[0072] Step S410. Based on the relative position of the fragment with respect to the bounding box range, obtain the data of the target channel of the fragment;

[0073] Step S420: Using the data of the target channel of the fragment, obtain the height variation range of the fragment.

[0074] In the following, step S410 and step S420 will be further explained and illustrated. Specifically, after the relative position of the target model's fragment relative to the target model's bounding box range is obtained, since the relative position of the target model's fragment relative to the target model's bounding box range is a three-dimensional position, the target channel data of the target model's fragment can be obtained based on the relative position. Since the brightness of the character in the game gradually decreases from top to bottom, the shielding effect at the point of contact with the ground should be the strongest, the target channel can be the y channel; after the y channel data is obtained, based on the obtained y channel data, the gradual change of the upper and lower heights of the target model can be obtained, that is, the height variation range of the target model's fragment can be obtained.

[0075] Furthermore, in this exemplary embodiment, after obtaining the height variation range of the target model's fragments, the height variation range of the target model's fragments can be input into the occlusion channel of the target model material, and the overall ambient light occlusion effect of the target model can be achieved through the height variation range in the occlusion channel. Figure 5 As shown, after the height variation range of the fragment is input into the occlusion channel, the ambient light occlusion implementation method may further include step S510 and step S520:

[0076] Step S510: acquiring a first shielding parameter corresponding to the height variation range of the fragment, and generating and displaying a shielding intensity parameter corresponding to the first shielding parameter;

[0077] Step S520: In response to the setting operation for the shielding intensity parameter, a first parameter value is obtained, wherein the first parameter value is used to adjust the shielding height of the target model.

[0078] In the following, step S510 and step S520 will be further explained and illustrated. Specifically, after the overall ambient light occlusion effect of the target model is realized in the material, a visual overall ambient light occlusion effect adjustment scheme can also be generated for the artist to adjust the overall ambient light occlusion effect. First, a first occlusion parameter corresponding to the height variation range of the fragment of the target model is obtained, and the value range of the first occlusion parameter is [0,1]. A occlusion intensity parameter corresponding to the first occlusion parameter is generated. The occlusion intensity parameter is visible. The visible occlusion intensity parameter is located in the game engine. The artist can adjust the visible occlusion intensity parameter as needed to adjust the overall ambient light occlusion effect of the target model; when the artist adjusts the occlusion intensity parameter, in response to the artist's setting operation for the occlusion intensity parameter, a first parameter value is obtained based on the setting operation, and the first parameter value is used to adjust the occlusion height of the target model. Figure 6The overall ambient occlusion effect of the target model achieved through the occlusion channel of the material is shown. It can be seen that Figure 6 In the figure, the brightness of the target model's fragments gradually decreases from top to bottom, and the shielding effect is strongest at the point where it contacts the ground. Figure 7 The figure shows the overall ambient light occlusion effect of the fragment of the target model after the artist adjusts the visible occlusion strength parameter to 0.5 in the game engine. When the artist adjusts the visible occlusion strength parameter, the larger the occlusion strength parameter is set, the higher the occlusion height of the target model from the ground contact point. In this example embodiment, by generating a visible occlusion strength parameter corresponding to the first occlusion parameter, the artist can adjust the occlusion effect of the target model without modifying the map, saving time and labor costs.

[0079] In step S130, an occlusion map of the target model is generated, and grayscale processing is performed on the occlusion map to obtain a target occlusion map, and detailed ambient light occlusion of the target model is achieved through the target occlusion map.

[0080] In this example embodiment, in addition to inputting the height variation range of the target model's fragment into the material's occlusion channel to achieve the overall ambient light occlusion effect of the target model through the occlusion channel, the detailed ambient light occlusion effect of the target model can also be achieved. When achieving the detailed ambient light occlusion effect of the target model, first, an occlusion map of the target model is generated. The generating of the occlusion map of the target model includes:

[0081] The target model is imported into a texture synthesizer, and an occlusion map of the target model is generated by the texture synthesizer.

[0082] Specifically, the target model can be imported into a texture synthesizer, and the occlusion map of the target model can be generated by the texture synthesizer. The texture synthesizer can be Substance Designer or other texture synthesizers, and the texture synthesizer is not specifically limited in this exemplary embodiment.

[0083] In this example embodiment, after the occlusion map of the target model is generated, the occlusion map of the target model can be processed to obtain a target occlusion map. Figure 8 As shown, grayscale processing is performed on the occlusion map to obtain a target occlusion map, which may include steps S810 to S830:

[0084] Step S810: Obtain the pixel matrix of the occlusion map, and perform normalization processing on the pixel matrix of the occlusion map;

[0085] Step S820: performing exponential transformation on the normalized pixel matrix using a contrast algorithm;

[0086] Step S830: Denormalize the pixel matrix that has undergone the exponential transformation, determine the denormalized pixel matrix as the target pixel matrix, and obtain the target occlusion map through the target pixel matrix.

[0087] The following will further explain and illustrate step S810-step S830. Specifically, first, the pixel matrix of the occlusion map is obtained, and after the pixel matrix of the occlusion map is obtained, the pixel matrix of the occlusion map is normalized to obtain a normalized pixel matrix; then, the normalized pixel matrix is ​​exponentially transformed using a contrast algorithm, wherein the equation for the exponential transformation can be: f = c*R γ , where c is a constant, R is the grayscale of the occlusion map, and γ is the gamma coefficient. After the normalized pixel matrix is ​​exponentially transformed by the contrast algorithm, the exponentially transformed pixel matrix is ​​denormalized, and the denormalized pixel matrix is ​​determined as the target pixel matrix; finally, the target occlusion map is obtained by the target pixel matrix.

[0088] After the target occlusion map is obtained, the target occlusion map can be used to achieve the detailed ambient occlusion effect of the target model. Fig. 9 It shows that the detailed ambient light occlusion effect of the target model is achieved through the target occlusion map. The target occlusion map can simulate the shadows between objects. When there is no lighting, the volume of the target model is increased, and the three-dimensional sense of the target model is further enhanced.

[0089] In this example embodiment, reference Fig.10 As shown, after obtaining the target occlusion map, the ambient light occlusion implementation method may further include step S1010 and step S1020:

[0090] Step S1010. Acquire a second masking parameter corresponding to the target pixel matrix, and generate and display a detail masking intensity parameter corresponding to the second masking parameter;

[0091] Step S1020: In response to the setting operation of the detail masking strength parameter, a second parameter value is obtained, wherein the second parameter value is used to adjust the detail masking strength of the target model.

[0092] In the following, step S1010 and step S1020 will be further explained and illustrated. Specifically, after the detail ambient occlusion effect of the target model is realized in the material, a visual detail ambient occlusion effect adjustment scheme can also be generated for the artist to adjust the detail ambient occlusion effect of the target model. First, a second occlusion parameter corresponding to the target pixel matrix is ​​obtained, wherein the value range of the second occlusion parameter is [0,1], and a detail occlusion intensity parameter corresponding to the second occlusion parameter is generated and displayed, wherein the detail occlusion intensity parameter is visible, and the visible detail occlusion intensity parameter is located in the game engine, and the artist can adjust the visible detail occlusion intensity parameter as needed to adjust the detail ambient occlusion effect of the target model. When the artist adjusts the detail occlusion intensity parameter, in response to the artist's setting operation for the detail occlusion intensity parameter, a second parameter value is obtained according to the setting operation, wherein the second parameter value is used to adjust the detail occlusion intensity of the target model. When an artist adjusts the visible detail occlusion intensity parameter, the larger the detail occlusion intensity parameter is set, the greater the detail ambient occlusion intensity of the target model.

[0093] The ambient light occlusion implementation method provided by the exemplary embodiment of the present disclosure has at least the following advantages: on the one hand, the relative position of the fragment of the target model with respect to the bounding box range is first calculated to obtain the height variation range of the fragment, and the height variation range of the fragment is input into the occlusion channel. The overall ambient light occlusion effect of the target model is adjusted through the occlusion channel, which solves the problem that the occlusion effect of the model in the picture cannot be adjusted separately in the related art, and improves the efficiency of realizing the overall ambient light occlusion effect of the model; on the other hand, after achieving the overall ambient light occlusion effect of the target model, an occlusion map of the target model is generated, and the occlusion map is applied to the occlusion map. After processing is performed, a target occlusion map is obtained, through which the effect of detailed ambient occlusion of the target model is achieved, thereby further enhancing the three-dimensional sense of the target model; on the other hand, after the overall ambient occlusion effect of the target model and the detailed ambient occlusion effect of the target model are achieved through the material, a visible occlusion intensity parameter and a detailed occlusion intensity parameter are generated, so that the artist does not need to modify the map, but only needs to adjust the occlusion intensity parameter and the detailed occlusion intensity parameter to achieve the adjustment of the overall ambient occlusion effect of the target model and the detailed ambient occlusion effect of the target model, thereby saving time and labor costs.

Among them:

[0095] A relative position determination module 1110 is used to obtain a target model and a bounding box range of the target model, and determine a relative position of a fragment of the target model relative to the bounding box range;

[0096] The overall ambient light occlusion realization module 1120 is used to obtain the height variation range of the fragment based on the relative position of the fragment relative to the bounding box range, input the height variation range of the fragment into the occlusion channel, and realize the overall ambient light occlusion of the target model through the occlusion channel;

[0097] The detailed ambient occlusion implementation module 1130 is used to generate an occlusion map of the target model, perform grayscale processing on the occlusion map to obtain a target occlusion map, and implement detailed ambient occlusion of the target model through the target occlusion map.
