Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "comprising" and "having," and any variations thereof, as referred to in the embodiments of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In the game engine, the light sources may be divided into real-time light (real time) and baking light (cake). Wherein the real-time light is split into pixel-based and vertex-based. The illumination operation effect based on the pixels is closer to reality. The vertex-based illumination calculation is less expensive, but depends on the number of vertices, and therefore the illumination calculation is not fine enough and does not represent texture well. In summary, all the shadows of real-time light are real-time operation, so the effect is real, but the consumption is large.
The baking light is to bake the illumination information into an illumination map (lightmap), so that the calculation consumption is low, but the illumination map can only record illumination brightness change based on a model, and cannot present highlight change of material normal map details.
When a game engine is used to make a scene, a small number of real-time point light sources are sometimes used to illuminate a part to express the texture of a dark part, especially the texture of a metal or a smooth part. However, the real-time light source is relatively expensive to calculate, and it is difficult to represent the texture of the object in the dark portion by using another scheme instead of the real-time light source without substantially affecting the illumination expression effect.
Although the partially reflective probe may serve this purpose, if in a dark environment, the partially reflective probe should be adapted to the dark effect of the environment, otherwise the objects in the scene affected by the partially reflective probe may be out of the environment. If the subjective treatment is carried out, like the lighting of a movie, the real-time light source is used for lighting the texture of an object by supplementing the light source in the dark part. However, the real-time light source has high performance consumption, which is not favorable for optimizing the efficiency of game operation, and especially for platforms of terminals such as mobile phones, the efficiency optimization is more important.
At present, a real-time point light source can be used for supplementing light to a dark part, so that a model made of the PBR material can generate real highlight reaction which accords with texture under real-time light. For example, in general pipeline rendering, the number of real-time point light sources received by an object is four, and if the requirement for efficiency optimization is small, at most one real-time point light source can be received, even the real-time point light source is not used, so that the performance consumption is saved.
The existing method can embody the illumination realization effect with higher quality, and can achieve the required effect by real-time light distribution like film lighting. The method for utilizing the real-time point light source has strong controllability, intuitive effect and higher quality. However, the game is very expensive to run, and the use of real-time point light sources is limited, so that the appearance of the scene is greatly reduced. Even though the custom reflection map of the conventional local reflection probe can also simulate the light source to a certain extent, the cost for finding a proper reflection map is high, the method is difficult to adapt to the environment of each game scene, and the modification cost of the reflection map is high.
Based on this, the embodiment of the application provides a method and a device for generating reflected illumination data in a game and a computer device, and the technical problem that performance consumption is large during game running so that the running efficiency of the game is affected can be solved through the method.
Embodiments of the present invention are further described below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a method for generating reflected light data in a game according to an embodiment of the present application. The game scene of the game comprises an original point light source and a PBR material model. As shown in fig. 1, the method includes:
in step S110, a self-luminous object is set in the game scene.
Wherein the self-luminous object is used for simulating an original point light source. It should be noted that the Point Light source (Point Light) in the embodiment of the present application is a Light source that diverges from one Point to four sides in the game engine, for example, a Point Light source object such as a lamp and a candle in a game scene. The self-luminous object (fake light) in the embodiment of the present application is a self-luminous material object for simulating the point light source (i.e. the original point light source).
In practical applications, in order to make the self-luminous object more approximate to the original effect of the original point light source, the self-luminous object needs to be disposed at an appropriate angle and position. For example, as shown in FIG. 2, the placement and placement of self-illuminating objects may be determined by the computer device according to parameters or operations configured by the game designer. Furthermore, the loudness and color of the self-lighting object may also depend on the real-time light effect of the original point source to be simulated.
And step S120, setting a local reflection probe at a preset position in a game scene.
Wherein the partial reflection probe is used for collecting reflection data of light received from the light-emitting object. The partial reflection probe (reflection probe) can be understood as a reflection sphere used for simulating environmental reflection in a game engine, and can collect reflected light data of the surrounding environment in real time, and reflected light data can be obtained by baking the surrounding environment.
It should be noted that the PBR material in the PBR material model refers to a material that can implement the whole rendering algorithm or process close to the physical reality, and can also be understood as a material of the surface of an object that can interact with light in the real world. Illustratively, there are two cases after the lamp light irradiates the surface of the object, reflection or refraction of the lamp light which continues to advance. For example, in the case of a conductor, i.e., a metal, the reflectivity is generally high, so that most of the light bounces back in the form of specular reflection, and a small portion of the light is completely absorbed after being refracted. The reflection data of light in the embodiment of the present application refers to the reflection data generated after the light is irradiated to the PBR material model with metal smooth texture.
For example, the computer device may provide a local reflection probe on an object (e.g., a certain PBR material model) that is locally affected by the original point light source. For example, as shown in FIG. 3, the computer device may set a new blank partial reflection probe at a specified location in the game scene based on the position of the partial reflection probe set by the game designer and its parameters. To facilitate the subsequent baking process, the partial reflection probe may also be set to a bake (bake) mode.
In this step, the computer device may set one or more local reflection probes in the game scene, and the local reflection probes may affect the model within a certain range around the local reflection probes.
And S130, baking the PBR material model in the action range of the local reflection probe based on the reflection data to obtain the reflection illumination data of the original point light source acting on the PBR material model.
The baking in the embodiment of the present application refers to baking an illumination map of a game scene in advance before the game is run by using an illumination map (Lightmap) technology based on the calculated illumination, and the illumination map baked in advance can be directly used when the game is run. The illumination map can record illumination brightness change based on the model, and highlight change of material normal map details can be presented.
In this step, the computer device performs baking based on the reflection data of the light collected by the partial reflection probe in step S120, so as to realize the reflection data generated by the self-luminous object light collected by the partial reflection probe, and simulate the reflection effect of the original point light source on the PBR material model. For example, a highlight effect representing the texture of the model is generated at a position corresponding to the model affected by the local reflection probe, and the metallic texture of the metal in the dark part and the smooth object can be more remarkably represented by the highlight generated similarly to the influence of the point light source.
Through setting up the self-luminous object that is used for simulating original pointolite to and set up the local reflection probe that is used for gathering the reflection data to self-luminous object light, can gather the reflection data of the light that the analog body of original pointolite produced to PBR material model, in order to embody comparatively real reflection effect, bake this reflection data to reflection illumination data in, can directly use this reflection illumination data when the game operation, need not real-time calculation, can save the consumption of performance, thereby realized reducing the consumption of game operation when comparatively real reflection effect restores.
The above steps are described in detail below.
In some embodiments, the self-illumination of the original point light source can be realized in a baking mode, and the performance consumption of game running is further reduced. As an example, the method may further comprise the steps of:
step a), collecting point light source illumination data of an original point light source;
and b), baking based on the reflected illumination data and the point light source illumination data to obtain an integral illumination map.
For example, as shown in fig. 4, the original point light source is also set to a baking (bake) mode, that is, the original point light source originally used for real-time operation is set to a baking mode, so that when the global illumination map is baked, the self-illumination data of the original point light source can be collected on the illumination map. The original real-time point light source is baked instead, and then local brightness can be illuminated through the illumination map.
In the embodiment of the application, the whole game scene needs to be baked, so that the original point light source data is collected by the illumination map, the self-luminous object is collected by the local reflection probe, the lightness of the object in the action range is influenced by the real-time light instead of the local reflection probe, the two functions take effect together, and the illumination and reflection effects of the real-time point light source are simulated.
The illumination and reflection effects of the real-time point light source can be simulated under the conditions of low operation consumption and low cost by combining the baking of the original point light source with the baking of the reflection data, the efficiency is optimized, meanwhile, the requirements of the art can be met, and the efficiency and the effects are met.
For example, as shown in fig. 5, conventional real-time computing illumination can embody the light source and the metal texture effect under real-time light, but the performance consumption is large; as shown in fig. 6, the metallic texture effect of the local reflected light cannot be expressed under the baking light only by the baking light; as shown in fig. 7, according to the method provided by the embodiment of the present application, a self-luminous object is used as a pseudo light source, reflected light generated by the self-luminous object is collected by using a local partial reflection probe on a model, and reflected light data of the local reflection probe and illumination data of an original point light source are baked, so that illumination and reflection effects of the point light source can be increased, and the performance consumption can be greatly reduced.
In some embodiments, multiple partial reflection probes may be placed on several PBR material models that require reflection effects. As an example, the number of PBR material models is plural; and at least one local reflection probe is arranged at the preset position of each PBR material model.
Through a plurality of partial reflection probes, the PBR material model with the reflection effect is enabled to generate the reflection effect, the generation position of the partial reflection effect in the whole game scene can be set according to the game requirement, and the reflection effect is enabled to be more flexible.
Based on this, different levels of partial reflection probes can be utilized to achieve the creation or absence of certain reflection effects. As an example, a plurality of partial reflection probes are arranged at preset positions of each PBR material model; a plurality of local reflection probes corresponding to each PBR material model correspond to different reflection priorities; the step S130 may include the following steps:
step c), determining a target local reflection probe according to the sequence of the reflection priorities;
and d), baking the PBR material model within the action range of the target local reflection probe based on the target reflection data corresponding to the target local reflection probe to obtain the reflection illumination data of the original point light source acting on the PBR material model.
For step c) above, the reflection priorities of the plurality of partial reflection probes are, for example, 0 (lowest priority), 1, 2, and 3 (highest priority), respectively. And determining the partial reflection probes needing to generate the reflection effect according to the priority of the reflection priorities (namely the priority of the reflection priorities), namely preferentially determining to use the partial reflection probes of the 3 level (namely the target partial reflection probes) and not using the partial reflection probes of the 0 level, the 1 level and the 2 level.
For the step c), baking may be performed based on the target reflection data corresponding to the reflection data of the 3-level partial reflection probe (i.e., the target partial reflection probe), for example, after the step c).
In addition, the priority of the partial reflection probe can be set in the position setting process. For example, a local reflection probe is set for a model which is locally affected by an original point light source, and the priority of the local reflection probe is increased, that is, the import priority of the local reflection probe is set to be increased (the increase is defaulted to 0), and the specific priority level to be increased may depend on the number of surrounding local reflection probes and the display priority thereof.
In the embodiment of the application, the plurality of partial reflection probes can be nested in a plurality of layers according to levels, whether the partial reflection probes generate reflection influence on the PBR material model or not is set according to the priority levels, for example, the high-priority partial reflection probes cover the low-priority partial reflection probes, and therefore the reflection effect can be set more flexibly according to the regional requirement.
In some embodiments, the location of the partially reflective probe may be directly above the PBR material model. As one example, a partial reflection probe is placed on top of the PBR material model. The computer equipment can place the local reflection probe according to the position through the position on the PBR material model, so that the reflection data acquired by the local reflection probe more conforms to the actual condition of the PBR material model.
Based on this, the preset position of the partial reflection probe can be determined manually or according to a default position. As an example, the partial reflection probe is placed at a central position above the PBR material model or at a position determined according to the input operation. The preset position of the partial reflection probe can be flexibly set through manual input operation or system default of the central position of the PBR material model and other modes.
In some embodiments, the reflection intensity of the partial reflection probe may also adjust the setting. As one example, the parameters of the partial reflection probe include a reflected light intensity parameter. The reflection intensity of the local reflection probe can be adjusted and set more flexibly according to the requirement through the reflection light intensity parameter of the local reflection probe.
Of course, the setting can be flexibly adjusted in the aspects of the intensity and the color of the self-luminous object and the like. As an example, the parameters of the self-luminous object include any one or more of: self-luminous intensity parameter, self-luminous color parameter, self-luminous angle parameter and collected reflection data.
The self-luminous object can be closer to the original point light source effect by adjusting the specific self-luminous parameters of the self-luminous object, the angle, the intensity, the color and the like of reflected highlight generated by the self-luminous object can be changed along with the adjustment of the self-luminous object, and the reflection effect is updated by quickly baking the local partial reflection probe.
In some embodiments, the self-illuminating objects may be used only for the baking process of the illumination pattern, and need not be loaded while the game is running. As one example, the label of the self-luminous object is set to the edit-only display mode. For example, a label (tag) of a self-luminous object is set to be displayed only at the time of editing (editorOnly), and a special layer (layer) can be set for the self-luminous object, so that the self-luminous object can be accurately controlled to be collected only by a required partial reflection probe.
In some embodiments, the position of the self-illuminating object can be set in terms of the direction of the original point source relative to the partially reflective probe, which can also depend on the angle at which highlight is desired to appear. As one example, the self-luminous objects are disposed at arbitrary positions on the spatial line segment; the spatial line segment is a line segment formed between the original point light source and the local reflection probe. The self-luminous object is arranged on the line segment formed between the original point light source and the local reflection probe, so that the highlight angle of the reflected light is more appropriate, and the reflection highlight effect is more vividly displayed.
Of course, the self-luminous objects can be arranged at other more specific exact positions. As one example, a self-luminous object is disposed at an original point light source. The positions of the self-luminous object and the original point light source are kept consistent, so that the highlight effect of the reflected light can better accord with the position of the actually simulated original point light source.
As another example, the self-luminous objects are disposed around the local reflection probe, for example, when one self-luminous object is placed in the spatial line segment closer to the local reflection probe, the local reflection probe can more efficiently collect the reflection data generated by the self-luminous object.
Fig. 8 provides a schematic structural diagram of a generation apparatus of reflected light data in a game. The game scene of the game comprises an original point light source and a PBR material model. As shown in fig. 8, the apparatus 800 for generating in-game reflected light data includes:
