Description

[0002] In the rendering production of a virtual scene, the light effect (such as the reflection light effect or the light transmission effect) of a virtual model of metal or glass material is often processed. One of the technical ideas of the light effect processing is to simulate the use of a circular polarizing lens (or filter lens, Circular-Polarizing Lens, CPL) in a real photography scene to filter the reflected light and thus improve the picture clarity and color concentration. For this purpose, the technicians in the field try various material processing methods or picture rendering methods to realize the filter lens effect rendering of the virtual model.

[0003] In the related art, one filter lens effect rendering method is to control the corresponding variables or expressions respectively for the multiple parameters of the physically based rendering (PBR) material of the virtual model, so as to render the filter lens effect of the virtual model. However, the defect of this method is that the multiple parameters are independent of each other, the adjustment is difficult, and the filter lens effect that changes with the rotation of the camera angle cannot be realized.

[0004] In the related art, another filter lens effect rendering method is to adjust the global light of the virtual scene as a whole in the rendering process to control the light effect (such as the reflection light effect of the bright and dark parts) of the virtual model of metal or glass material. However, the defect of this method is that only the overall light adjustment of the virtual model in the virtual scene is realized, and the effect of improving the picture level that the filter lens can achieve cannot be simulated.

[0027] Those skilled in the art can understand that Figure 1 The structure shown is only schematic, which does not limit the structure of the above-mentioned mobile terminal. For example, the mobile terminal can include more or fewer components than those shown in Figure 1 , or have a different configuration from Figure 1 .

[0028] According to an embodiment of the present application, an embodiment of a virtual model filter lens effect rendering method is provided. It should be noted that the steps shown in the flowchart of the drawing can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from here.

[0029] In a possible implementation, the embodiment of the present application provides a virtual model filter lens effect rendering method running on the above-mentioned mobile terminal.Figure 2 is a flowchart of a method for rendering a virtual model with a filter effect according to an embodiment of the present application, as shown in Figure 2 The method comprises the following steps:

[0030] In step S21, a first map and an optical perspective parameter are obtained, wherein the first map is a material map of the virtual model, and the first map is determined by a material type of the virtual model, and the optical perspective parameter is used to determine an optical performance of the filter effect of the virtual model.

[0031] The virtual model can be a virtual model (such as a virtual character, a virtual item, etc.) to be rendered with a filter effect in a virtual game scene. The game type corresponding to the virtual game scene can be: action (for example: first-person or third-person shooting game, two-dimensional or three-dimensional fighting game, war action game, and sports action game, etc.), adventure (for example: exploration game, collection game, puzzle game, etc.), simulation (for example: sand table simulation game, simulation raising game, strategy simulation game, city construction simulation game, business simulation game, etc.), role-playing, and leisure (for example: chess table game, leisure competition game, music rhythm game, dressing-up raising game, etc.) and the like.

[0032] The material type of the virtual model can be a virtual material related to the filter effect. For example, the material type can be a glass material or a metal material. The virtual model can be a virtual glass lens, a virtual glass prop, a virtual metal ball, a virtual metal prop, etc.

[0033] The first map can be a material map of the virtual model. The material map can be determined by the material type of the virtual model. The specific implementation process of determining the material map by the material type of the virtual model can be, but is not limited to: determining the material type of the virtual model to be rendered, then selecting the corresponding material map from the material map database pre-set by the technical personnel according to the material type, or requiring the technical personnel to select or input the material map in real time according to the material type.

[0034] The optical perspective parameter can be a pre-created integrated parameter. The optical perspective parameter can be used to determine the optical performance of the filter effect of the virtual model, wherein the optical performance can include: reflected light intensity, reflected light range (virtual and real visual performance of reflected light), refraction light effect, etc. By integrating multiple parameters related to the filter effect of the virtual model into one optical perspective parameter, the rendering or modification process can be controlled by controlling the one optical perspective parameter, thereby completing the rendering of the filter effect of the virtual model, improving the rendering convenience, and reducing the rendering difficulty.

[0035] Specifically, the obtaining the first map can further include other method steps, which can be referred to the further introduction of the embodiments of the present application below, and details are not described herein.

[0036] In step S22, a first mask is generated based on the first map and the optical perspective parameter, wherein the first mask is used to render a filter effect of a first region, and the first region is an edge region of the virtual model.

[0037] The first region can be an edge region of the virtual model. The edge region of the virtual model can be a region near an edge of a projection (i.e., a two-dimensional display picture) of the virtual model on the graphical user interface. The size of the region can be specified by a technician in advance.

[0038] The first mask can be used to render a filter effect in the first region. Since the material of the virtual model can be a material related to a filter effect such as metal or glass, when a light source of a virtual scene is incident on the virtual model, a more obvious edge reflection light can be generated in the edge region of the virtual model. In the edge region of the virtual model (equivalent to the first region), the first mask can be used to render a filter effect (for example, an edge reflection light effect).

[0039] Based on the material map of the virtual model and the optical perspective parameter, the first mask corresponding to the virtual model can be generated. The material map can be a map variable, and the optical perspective parameter can be a pre-created integrated parameter. Thus, the filter effect rendering method of the virtual model can be flexibly reused by replacing the material map and / or adjusting the optical perspective parameter.

[0040] Specifically, the generating the first mask based on the first map and the optical perspective parameter can further include other method steps, which can be referred to the further introduction of the embodiments of the present application below, and details are not described herein.

[0041] In step S23, the first map is optically rendered based on the optical perspective parameter to obtain a second map, wherein the second map is used to render a filter effect of a second region, and the second region is a to-be-displayed region except the edge region of the virtual model.

[0042] The second region is a to-be-displayed region except the edge region of the virtual model. For example, when the virtual model is a virtual glass ball, the first region is an edge annular region when the virtual glass ball is displayed in the graphical user interface, and the second region is a central circular region surrounded by the edge annular region.

[0043] The second map can be a map for rendering the filter effect in the second area of the virtual model. The second map can be obtained by performing the optical performance processing on the material map of the virtual model. The optical performance processing can be performed according to the optical view parameter. For example, the optical performance processing can be a saturation adjustment processing, a brightness adjustment processing, a layer mixing processing, a color interpolation processing, and the like performed on the material map of the virtual model.

[0044] Specifically, the optical performance processing on the first map to obtain the second map according to the optical view parameter can further include other method steps, which can be referred to the further introduction of the embodiments of the present application below, and will not be described here.

[0045] In step S24, the filter effect of the virtual model is rendered based on the first mask and the second map.

[0046] The rendering engine for performing the rendering step can be a commonly used engine such as Unreal 4 (UE4) game engine, Unreal 5 (UE5) game engine, Unity3D game engine, Redshift renderer, V-Ray image rendering engine, and Arnold image rendering engine.

[0047] With the rendering engine, the filter effect of the virtual model can be rendered based on the first mask and the second map. Specifically, based on the first mask, the filter effect of the edge area of the virtual model can be rendered; based on the second map, the filter effect of the other display area of the virtual model except the edge area can be rendered.

[0048] In at least some embodiments of the present application, first, a first map and an optical perspective parameter are acquired, wherein the first map is a material map of a virtual model, the first map is determined by a material type of the virtual model, and the optical perspective parameter is used to determine an optical performance of a filter effect of the virtual model. Then, a first mask is generated based on the first map and the optical perspective parameter, wherein the first mask is used to render the filter effect of a first area, and the first area is an edge area of the virtual model. Then, the first map is processed according to the optical perspective parameter to obtain a second map, wherein the second map is used to render the filter effect of a second area, and the second area is a display area other than the edge area of the virtual model. Thus, the filter effect of the virtual model is rendered based on the first mask and the second map, so as to achieve the purpose of rendering the filter effect of the virtual model based on the material type, the material map and the optical perspective parameter of the virtual model, thereby realizing the technical effect of improving the convenience and scalability of the filter effect rendering of the virtual model, and further solving the technical problem of difficulty in filter effect rendering and poor effect of the method of controlling material parameters or adjusting global lighting in related technologies.

[0049] The above method of the embodiments of the present application is further described below.

[0050] Optionally, in step S21, acquiring the first map can include the following execution steps:

[0051] In step S211, a material type of the virtual model is acquired, wherein the material type is a metal material or a glass material.

[0052] In step S212, the first map is determined according to the material type.

[0053] The material type of the virtual model described above can be a virtual material related to the filter effect. For example, the material type can be a glass material or a metal material. The virtual model can be a virtual glass lens, a virtual glass prop, a virtual metal ball, a virtual metal prop, etc.

[0054] The specific implementation of acquiring the material type of the virtual model described above can be determined by parameters (such as a preset material type identifier) corresponding to the virtual model, or determined by using a preset material type identification tool (such as a Metallic node in a preset game engine).

[0055] According to the material type described above, the material map of the virtual model is determined as the first map. The material map can be used to determine the characteristics (such as color, brightness, self-luminosity, opacity, etc.) of the PBR material corresponding to the virtual model when shading.

[0056] The specific implementation process of determining the first map according to the material type can be, but is not limited to, the following: determining the material type of the virtual model to be rendered, and then selecting the corresponding material map from the material map database preset by the technical personnel according to the material type, or requiring the technical personnel to select or input the material map in real time according to the material type.

[0057] Optionally, in step S22, generating the first mask based on the first map and the optical perspective parameter can include the following execution steps:

[0058] In step S221, in response to the material type corresponding to the first map being a metal material, a first parameter of the virtual model is calculated based on the optical perspective parameter, wherein the first parameter is used to determine the reflection light intensity corresponding to the first region;

[0059] In step S222, in response to the material type corresponding to the first map being a glass material, a first parameter is calculated based on the optical perspective parameter and a second parameter, wherein the second parameter is an index of refraction parameter corresponding to the glass material;

[0060] In step S223, the first mask is generated using the first map and the first parameter.

[0061] It is easy to understand that, in order to simulate a real photography scene, the metal material is a non-transparent material, so the reflection characteristics of the above metal material are considered, and the glass material is a transparent material, so the reflection characteristics and refraction characteristics of the above glass material are considered.

[0062] When the material type corresponding to the material map of the virtual model is a metal material, the optical performance calculation can be performed based on the optical perspective parameter to obtain a first parameter of the virtual model. The first parameter can be used to determine the reflection light intensity corresponding to the edge region of the virtual model. The reflection light intensity can be used as a basis for rendering the filter effect of the edge region of the virtual model.

[0063] When the material type corresponding to the material map of the virtual model is a glass material, the optical performance calculation can be performed based on the optical perspective parameter and the second parameter to obtain the reflection light intensity (equivalent to the first parameter) corresponding to the edge region of the virtual model. The second parameter can be an index of refraction (IOR) parameter corresponding to the glass material.

[0064] It should be noted that the optical perspective parameter can be a pre-created integrated angle parameter. The second parameter can be a preset constant value determined by the technical personnel according to the index of refraction parameter of the common glass material in the real scene.

[0065] It should be noted that the optical performance calculation can be a calculation according to the law of optical nature (for example: Fresnel equation), which can be used to calculate the reflection light intensity of the metal material according to the integrated angle parameter, and can also be used to calculate the reflection light intensity of the glass material according to the integrated angle parameter and the second parameter.

[0066] Optionally, in step S223, generating the first mask using the first map and the first parameter can include the following execution steps:

[0067] Step S224, obtaining a third parameter of the virtual model, wherein the third parameter is used to determine a reflection light range corresponding to the first region;

[0068] Step S225, adjusting the orientation of the first map to obtain an adjustment result;

[0069] Step S226, generating the first mask based on the first parameter, the third parameter and the adjustment result.

[0070] The third parameter of the virtual model can be used to determine the display range of the edge reflection light corresponding to the edge region of the virtual model. The specific implementation process of obtaining the third parameter of the virtual model can be: obtaining the range parameter specified by the technician in advance as the third parameter, or determining the display range of the edge reflection light according to the rendering rule related to the virtual model to determine the third parameter.

[0071] The first map can be a material map of the virtual model. Adjusting the orientation of the first map can obtain the adjustment result. It is easy to understand that by adjusting the orientation of the first map, the orientation of the first map can be limited according to the requirements of the application scene, and the filter effect rendered based on the first map is further controlled.

[0072] The first parameter can be the reflection light intensity corresponding to the edge region of the virtual model. Based on the first parameter, the third parameter and the adjustment result, the first mask can be generated. The first mask can be used to render the filter effect corresponding to the edge region of the virtual model.

[0073] Optionally, in step S225, adjusting the orientation of the first map to obtain an adjustment result can include the following execution steps:

[0074] Step S2251, obtaining a virtual camera position corresponding to the virtual model;

[0075] Step S2252, adjusting the map orientation of the first map based on the virtual camera position to obtain an adjustment result.

[0076] The virtual camera position corresponding to the virtual model can be an observation position of a virtual camera in a virtual scene where the virtual model is located. The virtual camera position can be given in a position coordinate in a world space coordinate system. The virtual camera position can be used to determine an observation direction of the virtual camera.

[0077] The specific implementation process of obtaining the virtual camera position corresponding to the virtual model can be directly output by a preset game engine or pre-calculated by a technician.

[0078] Based on the virtual camera position, the mapping orientation of the first map can be adjusted to obtain the adjustment result. Specifically, the specific implementation process of adjusting the mapping orientation of the first map based on the virtual camera position can be: using a Camera Vector node in the preset game engine to process, so that the mapping orientation of the first map can always be consistent with the observation direction of the virtual camera.

[0079] It should be noted that the Camera Vector node can calculate the relationship between the RGB value of the first map and the distance from the first map to the virtual camera, and then determine the RGB value of the virtual model edge reflection light corresponding to the first map based on the coordinates of the first map in the world space according to the relationship, so as to ensure that the orientation of the first mask obtained from the first map is always consistent with the observation direction of the virtual camera.

[0080] It is easy to understand that by adjusting the mapping orientation of the first map, the mapping orientation of the first map is always consistent with the observation direction of the virtual camera in the virtual scene, which can further make the filter effect of the virtual model generated based on the first map more consistent with the performance of the real scene. Specifically, when the observation direction of the virtual camera in the virtual scene changes (for example, when the player controls the rotation of the virtual model), the filter effect corresponding to the current observation direction can be rendered in real time, thereby improving the experience of the player.

[0081] Optionally, in step S226, generating the first mask based on the first parameter, the third parameter and the adjustment result can include the following execution steps:

[0082] Step S2261, generating a second mask based on the first parameter, the third parameter and the adjustment result;

[0083] Step S2262, performing interpolation level processing on the second mask to obtain the first mask.

[0084] The first parameter can be used to determine the reflected light intensity corresponding to the edge region of the virtual model, the third parameter can be used to determine the reflected light range corresponding to the edge region of the virtual model, and the adjustment result is a map obtained after the first map is azimuthally adjusted. Based on the first parameter, the third parameter and the adjustment result, the second mask can be generated. The second mask can be an edge mask to be optimized for generating the first mask.

[0085] The specific implementation process of performing interpolation level processing on the second mask to obtain the first mask can be: generating an optimized mask corresponding to the second mask again using the optical natural law (for example, the Fresnel equation after approximation processing), and performing interpolation mixing (for example, average interpolation mixing) on the second mask and the optimized mask using the interpolation tool (for example, the Lerp node) provided by the preset game engine, and then obtaining the first mask.

[0086] It is easy to understand that by using the Fresnel equation after approximation to optimize the edge mask to be optimized (equivalent to the second mask), the level of the corresponding edge reflected light in the finally obtained first mask can be made more rich, and the intensity of the edge reflected light can change with the change of the observation direction of the virtual camera.

[0087] Optionally, in step S2261, generating the second mask based on the first parameter, the third parameter and the adjustment result can include the following execution steps:

[0088] Step S2263, obtaining the geometric shape of the first region;

[0089] Step S2264, generating a third mask according to the geometric shape based on the third parameter and the adjustment result;

[0090] Step S2265, generating a fourth mask according to the geometric shape based on the first parameter, the third parameter and the adjustment result;

[0091] Step S2266, performing division calculation on the third mask and the fourth mask to obtain the second mask.

[0092] The first region can be an edge region of the virtual model. The edge region of the virtual model can be a nearby region of the edge of the projection (i.e., a two-dimensional display picture) of the virtual model on the graphical user interface. The size of the nearby region can be specified by a technician in advance. The specific implementation process of obtaining the geometric shape of the first region can be: using a graphical recognition tool to recognize the edge region of the virtual model to obtain the geometric shape. For example, when the virtual model is a virtual metal sphere, the geometric shape is a circle corresponding to the size of the virtual metal sphere.

[0093] The third parameter can be used to determine the reflected light range of the edge region of the virtual model, and the adjustment result can be the first map after the orientation adjustment of the first map. Based on the third parameter and the adjustment result, the third mask can be generated according to the geometric shape. The third mask can be used to generate the second mask. For example, when the geometric shape is a circle corresponding to the size of the virtual metal sphere, the third mask can be

[0094] The first parameter can be used to determine the reflected light intensity of the edge region of the virtual model. Based on the first parameter, the third parameter and the adjustment result, the fourth mask can be generated according to the geometric shape. The fourth mask can be used to generate the second mask.

[0095] It is easy to understand that the third mask and the fourth mask can be two masks with the same geometric shape but different sizes. For example, the third mask is a circular mask with a smaller radius, which is used to determine the inner boundary of the edge region; the fourth mask is a circular mask with a larger radius, which is used to determine the outer boundary of the edge region; the centers of the third mask and the fourth mask can coincide or not coincide (determined by the technical personnel according to the application scene requirements).

[0096] The third mask and the fourth mask are divided to obtain the second mask. Specifically, the specific implementation process of dividing the third mask and the fourth mask can be: using the Subtract node provided by the preset game engine to divide the third mask and the fourth mask to obtain the second mask.

[0097] It is easy to understand that the process of dividing the third mask and the fourth mask can be visually represented as: subtracting the area corresponding to the third mask with a smaller radius from the area corresponding to the fourth mask with a larger radius. In particular, when the centers of the fourth mask and the third mask coincide, the shape of the second mask obtained by dividing the third mask and the fourth mask is annular, and the center of the annular ring coincides with the center.

[0098] Optionally, in step S23, the second map can be obtained by performing the following steps according to the optical perspective parameter:

[0099] In step S231, the saturation of the first map is adjusted to obtain a third map, wherein the saturation of the third map is lower than that of the first map.

[0100] In step S232, the third map is adjusted according to the optical perspective parameter to obtain the second map.

[0101] The first map can be a material map of the virtual model. The material map can be used to determine the characteristics (such as color, brightness, self-luminosity, opacity, etc.) of the PBR material corresponding to the virtual model when shading.

[0102] The third map can be obtained by performing saturation adjustment on the first map. Specifically, the specific implementation of performing saturation adjustment on the first map can be: performing mapping processing on the saturation data corresponding to the first map, so that the range of the saturation data is between 0 and 1, to obtain a mapping result; and then using a desaturation tool (such as a DeSaturation node) provided by a preset game engine to process the mapping result of the first map, to obtain the third map. That is, the saturation of the third map is lower than that of the first map.

[0103] The optical perspective parameter can be a pre-created integrated angle parameter. The optical perspective parameter can be used to determine the optical performance of the filter effect of the virtual model. Using the optical perspective parameter, the third map can be adjusted for dark reflection, and the second map can be obtained. The second map can be used to render a map of the filter effect in the second region of the virtual model, and the second region is a to-be-displayed region excluding the edge region of the virtual model.

[0104] Optionally, in step S232, adjusting the third map for dark reflection using the optical perspective parameter to obtain the second map can include the following execution steps:

[0105] In step S2321, based on the fourth map, the fifth map, a preset constant parameter, and the optical perspective parameter, the third map is adjusted for dark reflection using a shape mask tool to obtain the second map, wherein the fourth map is a dark texture map corresponding to the virtual model, and the fifth map is a preset noise map.

[0106] The fourth map can be a dark texture map corresponding to the virtual model. The dark texture performance corresponding to the fourth map corresponds to the change of the dark region of the virtual model. The fifth map can be a noise map pre-set by a technician.

[0107] The preset constant parameter can be a constant parameter pre-set by a technician. The optical perspective parameter can be a pre-created integrated angle parameter. The optical perspective parameter can be used to determine the optical performance of the filter effect of the virtual model.

[0108] Based on the fourth map, the fifth map, the preset constant parameter and the optical perspective parameter, the dark reflection adjustment is performed on the third map by using the shape mask tool (for example, a spherical mask tool Sphere Mask provided by a preset game engine), and the second map is obtained.

[0109] Specifically, the dark reflection adjustment on the third map includes: performing coordinate transformation on the third map by using a coordinate transformation node (for example, a TransformVector node) of the shape mask tool, so that the coordinate information of the third map is changed to the world space; and performing orientation adjustment on the third map by using an orientation adjustment node (for example, a CameraVector node) of the shape mask tool, so that the map orientation of the third map is always consistent with the observation direction of the virtual camera.

[0110] Specifically, the dark reflection adjustment on the third map includes: based on the fifth map, performing mixing control on the third map by using the shape mask tool according to the preset constant parameter and the optical perspective parameter, adjusting the texture of the third map according to the position and observation direction of the virtual camera, and further improving the dark texture level of the third map; and then superimposing the adjusted third map and the fourth map to obtain the second map.

[0111] In summary, the technical scheme of the present application uses the material type, the material map and the optical perspective parameter based on the virtual model to perform the filter effect rendering of the virtual model, improves the convenience and expandability of the filter effect rendering of the virtual model, and solves the technical problems of the method of controlling material parameters or adjusting global light in related technologies, which has great difficulty in filter effect rendering and poor effect. The above scheme can be applied to scenes involving filter effect rendering in a third person shooting (TPS for short) game (for example, a virtual character observing a distance through a scope, observing a distance through a spherical water droplet, rendering of a virtual glass prop in a scene, etc.). The key technologies of the embodiments of the present application are described in detail as follows:

[0112] Figure 3 is a schematic diagram of a filter effect rendering process of a virtual model according to an embodiment of the present application, as Figure 3 shown, a polar angle parameter (equivalent to the optical perspective parameter) is created in advance by a technician to control the optical performance (for example, edge reflection intensity, dark reflection intensity of material, etc.) of the filter effect of the virtual model, and the polar angle parameter is controlled by a polar angle parameter node.

[0113] Still as Figure 3As shown, by the material node, the first map (i.e. the material map of the virtual model) can be obtained, and the material type corresponding to the first map can also be determined, which can be a metal material or a glass material.

[0114] Still as Figure 3 As shown, based on the Polar Angle provided by the Polar Angle parameter node, the edge reflection light intensity of the virtual model can be calculated by the Fresnel formula using the Schlick Phase Function node, the reflectivity node and the refractive index node, and the edge reflection light intensity is transmitted to the intensity parameter node.

[0115] Specifically, in the process of calculating the edge reflection light intensity of the virtual model by the Fresnel formula, the Fresnel formula used can be as shown in the following formula (1) to formula (2):

[0116]

[0117]

[0118] In the above formula (1) and formula (2), R p is the reflection light intensity of P-polarized light, R s is the reflection light intensity of S-polarized light, θ i represents the angle between the incident light and the normal, θ t represents the angle between the refracted light and the normal, n1 represents the refractive index of the medium where the incident light is located, and n2 represents the refractive index of the virtual model.

[0119] Further, based on the above formula (1) and formula (2), combined with the reflection law as shown in the following formula (3), the angle relationship as shown in the following formula (4) can be derived:

[0120] n1sinθ i = n2sinθ t Formula (3)

[0121]

[0122] Based on the above formula (1) to formula (4), the edge reflection light intensity of the virtual model can be calculated based on the Polar Angle provided by the Polar Angle parameter node, using the Schlick Phase Function node, the reflectivity node and the refractive index node.

[0123] Further, the Fresnel formula can be approximated by using the above-mentioned phase function (Schlick Phase Function) node to obtain more accurate edge light reflection intensity. Assuming that the reflectivity when the angle between the incident light and the normal line is 0 is the base reflectivity R0, the Fresnel approximation formula shown in the following formula (5) can be obtained: i = 0 is the base reflectivity R0, the Fresnel approximation formula shown in the following formula (5) can be obtained:

[0124] R = R0 + (1 - R0) (1 - cosθ i ) 5 Formula (5)

[0125] In the above-mentioned formula (5), R represents the actual reflectivity of the edge light.

[0126] In the above-mentioned phase function (Schlick Phase Function) node, cosθ i can be represented as the dot product of the incident light direction and the normal line. Accordingly, by controlling the numerical value of the initial reflectivity R0, cosθ i can be controlled, and the actual reflectivity R of the edge light can be obtained.

[0127] It should be noted that the above-mentioned pre-created polar angle parameter can be used to replace the numerical value of cosθ i in the calculation.

[0128] It should be noted that when the technical personnel set the reflectivity parameter for the metal material or set the reflectivity parameter for the glass material, the reflectivity parameter used in the rendering filter effect can be determined according to the reflectivity of the common metal material or the common glass material in the real scene.

[0129] Table 1

[0130] Metal \ Wavelength 800 nm 650 nm 500 nm Aluminum 86.7％ 90.5％ 91.8％ Silver 99.2％ 98.8％ 97.9％ Gold 98.0％ 95.5％ 47.7％ Copper 98.1％ 96.6％ 60.0％

[0131] For example, the reflectivity parameter value of the common metal shown in Table 1 can be selected by the technical personnel according to Table 1, and the reflectivity of the metal can be averaged to obtain the metal material reflectivity parameter to be used. When the selected target common metal is aluminum (Al), the average reflectivity calculated according to Table 1 is 0.89, and 0.89 can be used as a constant to be used as the metal material reflectivity parameter to be used. The reflectivity node is stored.

[0132] It should be noted that when the technical personnel set the refractive index parameter for the glass material, the refractive index parameter to be used can be determined according to the IOR parameter calibration value of the common material in the real scene. In this example, the refractive index parameter of the glass material to be used is calibrated to 1.5.

[0133] In addition, when rendering the filter effect for the virtual model of the glass material, the Opacity parameter of the glass material can also be set. In the real scene, the Opacity parameter of the common transparent colorless glass is usually 82% to 83%. In this example, the Opacity parameter is mapped and calculated so that the value of the Opacity parameter is between 0.1 and 0.2. The Opacity parameter can also be integrated into the Polar Angle parameter (equivalent to the above optical view angle parameter).

[0134] Still as Figure 3 shown, the specific implementation process of generating the edge light mask (equivalent to the above first mask) using the edge light reflection intensity provided by the intensity parameter node (hereinafter referred to as iris ratio, equivalent to the above first parameter) and the first map provided by the material node includes the following method steps:

[0135] Step E1, obtain the edge light display range (hereinafter referred to as pupil size, equivalent to the above third parameter) through the range parameter node;

[0136] Step E2, transform the map coordinates of the first map to the world space using the Transform Vector node, and adjust the orientation of the first map using the Camera Vector node so that the map orientation of the first map is always consistent with the observation direction of the virtual camera;

[0137] Step E3, generate the mask Mask1 based on the first map adjusted in the above step E2 and the pupil size using the mask node 1;

[0138] Step E4, multiply the above pupil size and the above iris ratio using the multiplication node 1;

[0139] Step E5, generate the mask Maks2 based on the first map adjusted in the above step E2 and the result obtained by the multiplication calculation in the above step E4 using the mask node 2;

[0140] Step E6, divide the mask Mask1 and the mask Maks2 to obtain the mask Mask3 using the division node;

[0141] Step E7, based on the Polar Angle parameter (equivalent to the above optical view angle parameter), generate the mask Y using the mapping node 1, the multiplication node 2, the preset parameter node 1, the preset parameter node 2 and the multiplication node 2, and use the Fresnel node (use the above approximate Fresnel formula) again;

[0142] Step E8, using an addition node, add the mask Y and the mask Mask3 obtained in the above step E6 (equivalent to the above interpolation level processing) to obtain a mask Mask4 (equivalent to the above first mask), which can be used to render the filter effect of the edge area of the virtual model.

[0143] Further, the first map is desaturated by using a DeSaturation node, and based on the desaturated first map, a dark texture map corresponding to the virtual model, and a preset noise map, a SphereMask is created by using a mask tool, and in combination with a polar angle parameter Polar Angle (equivalent to the above optical view angle parameter) and a preset constant parameter, a second map for rendering the filter effect in a second area (a to-be-displayed area other than the edge area) of the virtual model is obtained.

[0144] Figure 4 is a schematic diagram of a rotation effect of a second map rendering result according to an embodiment of the present application, as Figure 4 shown, based on the virtual model obtained by the above second map rendering, the intensity of the dark reflection of the virtual model can change with the rotation of the observation direction of the virtual camera. As Figure 4 shown before the rotation of the virtual camera, the intensity of the dark reflection of the virtual model is large, and the overall brightness of the virtual model is bright in visual performance. As Figure 4 shown after the rotation of the virtual camera, the intensity of the dark reflection of the virtual model is small, and the brightness of the dark part of the virtual model is small, and the brightness of other areas is large.

[0145] Figure 5 is a comparison diagram of a filter effect rendering of a virtual metal model according to an embodiment of the present application, as Figure 5 shown, the schematic diagrams before and after adjusting the filter effect of the virtual metal ball by the above filter effect rendering method of the virtual metal model are compared, it is easy to note that the saturation of the color of the rendering result after adjustment is higher than that of the rendering result before adjustment, and the picture level is stronger, and is closer to the filter effect in the real scene.

[0146] Figure 6 is a comparison diagram of a filter effect rendering of a virtual glass model according to an embodiment of the present application, as Figure 6 shown, the schematic diagrams before and after adjusting the filter effect of the virtual glass ball by the above filter effect rendering method of the virtual glass model are compared, it is easy to note that the effect of the edge light of the rendering result after adjustment is closer to the real scene than that of the rendering result before adjustment, and the picture level is stronger (as Figure 6The adjusted rendering result takes into account the light transmittance, the dark texture is more realistic, and is closer to the filter effect in the real scene.
