At present, the common global illumination implementation modes are mainly as follows: placing light sources in three directions, respectively baking the light sources three times from the three directions, separating brightness information of the light sources, combining the light sources into a light map recording brightness sources in the three directions, further calculating weights corresponding to three channels of the light map in a shader according to the source direction of the light source in the current direction in a three-direction coordinate space to obtain contribution of the light source direction to illumination brightness, and dyeing illumination of a dark part and the brightness according to the tone of a scene environment to obtain final indirect illumination.
However, on one hand, the data generation process of the above scheme is complex, and requires three separate bakes and then combines the data, and on the other hand, the above scheme requires a customized baking tool (e.g. houdini) and is costly because the general baking process only supports a single baking with a single direction of the main light source.
In an embodiment of the present disclosure, a scene rendering method is first provided, which overcomes, at least to some extent, the defect that the scene rendering method provided in the prior art requires an additional customized baking tool.
Fig. 1 is a flowchart illustrating a scene rendering method according to an exemplary embodiment of the present disclosure, where an execution subject of the scene rendering method may be a server that renders a game scene.
Referring to fig. 1, a scene rendering method according to one embodiment of the present disclosure includes the steps of:
step S110, creating an environment map according to the direction of a basic light source in a user-defined coordinate space; the user-defined coordinate space is obtained by rotating the coordinate axis of the world coordinate space;
step S120, baking the game scene after the color is removed according to the environment map to obtain an illumination map; the illumination map comprises illumination values of different pixel points in the game scene in different directions of the basic light source;
step S130, determining target illumination values of different pixel points of the target light source direction in the game scene according to the illumination map;
and step S140, determining the final illumination color according to the target illumination value and the input color information, and rendering the game scene according to the final illumination color.
In the technical solution provided in the embodiment shown in fig. 1, on one hand, an environment map is created according to a basic light source direction in a custom coordinate space (the custom coordinate space is obtained by rotating a coordinate axis of a world coordinate space), and different light source directions from the sky can be simultaneously stored in the environment map. Furthermore, the game scene after being decolored is baked according to the environment map to obtain the illumination map (the illumination map contains illumination values of different pixel points of different basic light source directions in the game scene), so that illumination distribution of different light source directions can be obtained only by baking once, the technical problems that in the related technology, three times of baking are needed from three directions respectively, the data processing flow is complex are solved, the data processing flow is simplified, the calculated data amount is reduced, the use of a memory is reduced, the performance in operation is improved, and single baking can be directly realized through a universal baking tool of an engine, the technical problem that in the related technology, a baking device needs to be customized is solved, and the development cost is reduced. On the other hand, the target illumination values of different pixel points of the target light source direction in the game scene are determined according to the illumination map, so that the technical problem that the data processing flow is complex due to the fact that the weights corresponding to three channels (RGB) of the illumination map need to be determined according to the current basic light source direction and then the contribution value of the current basic light source direction to illumination is calculated in the related technology is solved, and the related data processing flow is simplified. And determining the final illumination color according to the target illumination value and the input color information, rendering the game scene according to the final illumination color, displaying different illumination colors according to the tone of the game scene, and improving the immersion and fidelity of the game.
The following describes the specific implementation of each step in fig. 1 in detail:
it should be noted that, at present, the light source direction in the world coordinate space is generally adopted to perform the processing procedure of the correlated light mapping, however, referring to fig. 2, fig. 2 shows a schematic diagram of the customized coordinate space in an exemplary embodiment of the present disclosure, since the main light source of GI (Global illumination) is always generated from the sky, and the sun is not illuminated from the ground, in the world coordinate space (three-dimensional space formed by X, Y, Z, O is the origin of coordinates), the main light direction does not use the direction information of the lower hemisphere, so the spatial conversion is performed on the direction of the baking light source in the present disclosure, and the customized coordinate space (three-dimensional space formed by V0, V1, and V2) is obtained. Compared with a world coordinate space, the positive directions of all coordinate axes in the user-defined coordinate space are distributed on an upper hemisphere, so that illumination information based on all sky directions can be recorded more directly.
Specifically, a set of basis vectors (V) satisfying "two by two orthogonal, length 1, and trisecting the circumference corresponding to the XZ plane" can be obtained0，V1，V2) For example, the set of basis vectors satisfying the above condition may be:
taking an approximation thereof can yield: v0＝(0.8165，0.5774，0)，V1＝(-0.4082，0.5774，-0.7071)，V2(-0.4082, 0.5774, 0.7071), thus, may beSo as to determine the three-dimensional space defined by the basis vector as the self-defined coordinate space.
After the above basis vectors are obtained, the direction of the basis vectors may be determined as the direction of the base light source in the custom coordinate space.
With continued reference to FIG. 1, in step S110, an environment map is created according to the basic illuminant directions in the custom coordinate space.
In this step, referring to fig. 3, fig. 3 is a schematic flowchart illustrating a process of creating an environment map according to a basic light source direction in a custom coordinate space in an exemplary embodiment of the present disclosure, including steps S301 to S303, where step S110 is explained below with reference to fig. 3:
in step S301, the basis vectors are mapped to the spherical map to determine the pixel points corresponding to each basis vector.
In this step, a three-dimensional rectangular coordinate system may be established with the center of the spherical map as the origin of coordinates, and then, the pixel point corresponding to each base vector may be determined according to the three-dimensional rectangular coordinate system.
In step S302, the basis vectors are normalized, and the obtained normalized basis vectors are converted into color values.
In this step, normalization processing may be performed on the basis vectors to obtain normalized basis vectors, and the program code for implementing this step may be: spherepixplmnlz ═ normaize (spherepixelpos).
Wherein, the normalization processing is as follows: and keeping the direction of the vector unchanged, and enabling the length of the vector to be 1. Illustratively, the vector V0The normalized basis vector obtained after normalization may be V'0＝(a1，b1，c1)。
After obtaining the plurality of normalized basis vectors, the obtained normalized basis vectors may be converted into color values and stored, and the program code for implementing this step may be, for example: rgb (float 3) (saturrate (dot (V0, spherepixponmlz)), saturrate (dot (V1, spherepixponmlz)), saturrate (dot (V2, spherepixponmlz))).
In step S303, an environment map is generated according to the color value of each pixel point.
In this step, the color values of the pixels may be stored correspondingly to obtain an environment map. For example, when the color value is (0, 255, 0), it can be determined that the color of the pixel is red. Exemplarily, referring to fig. 4, fig. 4 shows a schematic diagram of an environment map generated under an HDR (High Dynamic Range Imaging) format 32 bits/channel condition in an exemplary embodiment of the present disclosure, where the condition may be changed according to actual conditions to obtain environment maps with different numerical accuracies.
With continued reference to fig. 1, in step S120, the game scene after the color removal is baked according to the environment map, so as to obtain an illumination map.
In this step, a game scene may be decolored first, and for example, a decoloring process may be implemented based on an engine shader, and the program code for implementing this step may be: desaturated trigilightmap dot (OriginalColor, float3(0.2126,0.7152,0.0722)), where OriginalColor represents the original light source color.
And baking the decolored game scene according to the environment map to obtain an illumination map, wherein the illumination map comprises illumination values of different pixel points of different basic light source directions in the game scene.
For example, the R channel in the illumination map (lightmap) may store the base luminaire direction V0In the game scene, the G channel can store the direction V of the basic light source according to the illumination values of different pixel points1In the illumination distribution of different pixel points in a game scene, the B channel can store the direction V of the basic light source2The illumination distribution of different pixel points in the game scene. Therefore, the method only needs to bake once, does not need to bake separately and then combine, simplifies the production process of the map, and can bake through the Messiah and Unity of the engine, UE4 and other general baking devices of the engine, does not need to customize the baking devices, and reduces the development cost.
The charting baking is a technology for rendering the illumination information into a charting and then pasting the baked charting back to the scene. In this way, the illumination information becomes the map, the CPU (Central Processing Unit) is not required to calculate time, and only the ordinary map is required to be calculated, so that the speed is extremely high.
In step S130, target illumination values of different pixel points of the target light source direction in the game scene are determined according to the illumination map.
In this step, referring to fig. 5, fig. 5 is a schematic flowchart illustrating a process of determining target illumination values of different pixel points of a target light source direction in a game scene according to an illumination map in an exemplary embodiment of the present disclosure, including steps S501 to S503, where step S130 is explained below with reference to fig. 5:
in step S501, the target light source direction is converted into a specified light source direction in the custom coordinate space.
In this step, the basis vector (V) of the customized coordinate space can be used0，V1，V2) The formed matrix is used as a conversion matrix between the world coordinate space and the custom coordinate space, and further, the target light source direction can be converted into the specified light source direction in the custom coordinate space based on the conversion matrix. Illustratively, the program code for implementing this step S501 may be:
float3 V0＝(0.8165,0.5774,0)；
float3 V1＝(-0.4082,0.5774,-0.7071)；
float3 V2＝(-0.4082,0.5774,0.7071)；
float3
TriGISunDir＝float3(dot(V0,SunDirWorld),dot(V1,SunDirWorld),
dot(V2,SunDirWorld))；
GILightingSimple＝max(0,dot(normalize(TriGISunDir),GILightmap))；
for example, when the scene displayed in the game is a 9 am scene, it may be determined that the target light source direction is a 9 am light source direction.
Illustratively, when the target light source direction is VpThe conversion matrix is (V)0，V1，V2) Then, the above-mentioned specified light source direction can be expressed as (V)p·V0，Vp·V1，Vp·V2)。
In step S502, normalization processing is performed on the designated light source direction to obtain a normalized direction.
In this step, the specified light source direction may be normalized to obtain a normalized direction. Illustratively, the resulting normalized direction may be (a2, b2, c 2).
In step S503, the target illumination values of different pixel points of the target light source direction in the game scene are determined according to the product of the normalized direction and the illumination value stored in the illumination map.
In this step, the target illumination values of different pixel points of the target light source direction in the game scene can be determined according to the product of the normalized direction and the illumination value stored in the illumination map. For example, after the illumination value (R1, B1, G1) of the pixel a is read from the illumination map, the illumination value may be normalized to obtain a target value (a3, B3, c 3).
Further, when the normalized direction is (a2, b2, c2), the target illumination value of the target light source direction at the pixel point a can be determined as: a2 a3+ b2 b3+ c2 c 3.
In step S140, a final illumination color is determined according to the target illumination value and the input color information, and the game scene is rendered according to the final illumination color.
In this step, after the target illumination value is obtained, different color information (for example, yellow is dyed to the illumination of a bright area, and gray is dyed to the illumination of a dark area) can be input according to the actual scene requirement, so as to dye the illumination of different pixel points. Specifically, the product of the target illumination value and the input color information may be determined as the final illumination color of the pixel point a. For example, when the input color value is (220,180,100), and the target illumination value a2 a3+ b2 b3+ c2 c3 is 0.5, the final illumination color of the pixel a may be (110,90, 50).
Furthermore, after the final illumination color of each pixel point is determined, the game scene can be rendered according to the final illumination color, so that the game scene presents a corresponding picture effect.
For example, referring to fig. 6A to 6E, fig. 6A to 6E show schematic diagrams of display effects of a game scene when the direction of a target light source is changed in an exemplary embodiment of the present disclosure, and it can be seen from the diagrams that the illumination effect in the present disclosure may be changed along with the change of the direction of the light source.
Based on the technical scheme, the method and the device for processing the data not only solve the technical problems that in the related technology, three times of baking are needed from three directions respectively, and the data processing flow is complex, simplify the data processing flow, reduce the calculated data amount, reduce the use of a memory, and improve the performance in operation, but also can be realized by a universal baking tool carried by an engine directly in a single baking mode, solve the technical problem that in the related technology, a baking device needs to be customized, and reduce the development cost.
The present disclosure also provides a scene rendering apparatus, and fig. 7 shows a schematic structural diagram of the scene rendering apparatus in an exemplary embodiment of the present disclosure; as shown in fig. 7, the scene rendering apparatus 700 may include an environment map generating module 701, a baking processing module 702, an illumination value determining module 703, and a rendering module 704. Wherein:
