Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The terms "comprising" and "having" and any variations thereof, as used in the embodiments of the present application, are intended to cover non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed but may optionally include other steps or elements not listed or inherent to such process, method, article, or apparatus.
In the game engine, the light sources may be classified into real time light (real time) and baking light (rake). Wherein real-time light is divided into pixel-based and vertex-based. The illumination operation effect based on the pixels is more real. Illumination operation based on vertices consumes less power, but is not fine enough and does not perform a good appearance of texture because it depends on the number of vertices. In the comprehensive view, the light and shadow of the real-time light are all calculated in real time, so that the effect is real, but the consumption is larger.
Baking light is to bake illumination information into an illumination map (lightmap), so that operation consumption is small, but the illumination map can only record illumination brightness change based on a model, and highlight change of material normal map details cannot be presented.
When a game engine is used to make a scene, a small amount of real-time point light sources are sometimes used to locally shine, so as to represent the texture of dark objects, especially the texture of metal and smooth objects. However, the operation of the real-time light source is relatively high in consumption, and it is difficult to replace the real-time light source with other schemes to represent the texture of the dark portion without substantially affecting the illumination effect.
While the partially reflective probe may be used to this effect, if in a relatively dark environment, the partially reflective probe should be adapted to the darker effect of the environment, otherwise objects in the scene affected by the partially reflective probe will be removed from the environment. If subjective processing is performed, like film lighting, real-time lighting is used to supplement the light source in the dark to make the texture of the object. However, the real-time light source has larger performance consumption, is unfavorable for optimizing the efficiency of game operation, and is more important for platforms of terminals such as mobile phones.
At present, a real-time point light source can be utilized to supplement light to the dark part, so that a model made of PBR material can generate real high-light response conforming to texture under real-time light. For example, in general pipeline rendering, the number of real-time point light sources accepted by one object is four, and if the requirement of efficiency optimization is small, one real-time point light source can be accepted at most, even the real-time point light source is not used, so that performance consumption is saved.
The existing method can show the high-quality illumination realization effect, and can realize the required effect by real-time light removal similar to film polishing. The method for utilizing the real-time point light source has strong controllability, visual effect and higher quality. However, the consumption of game play is large, and once the use of real-time point light sources is limited, the texture of the scene is greatly reduced. Even though the custom reflection map of the conventional local reflection probe can simulate the light source to a certain extent, the cost for finding a proper reflection map is high, the reflection map is difficult to adapt to the environment of each game scene, and the modification cost of the reflection map is also high.
Based on the above, the embodiment of the application provides a method and a device for generating reflected illumination data in a game and computer equipment.
Embodiments of the present invention are further described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for generating reflected illumination 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:
step S110, a self-luminous object is set in the game scene.
Wherein, self-luminous object is used for simulating original point light source. It should be noted that, point Light (pointlight) in the embodiments of the present application is a Light source that diverges from one Point to the periphery in a game engine, for example, a Light fixture, a candle, or the like in a game scene. In the embodiment of the present application, the self-luminous object (fake light) 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 similar to the original effect of the original point light source, the self-luminous object needs to be disposed at a proper angle and position. For example, as shown in FIG. 2, for placement and setting of self-luminous objects, the computer device may be determined according to parameters or operations configured by the game designer. Furthermore, the loudness color of the self-illuminating object may also depend on the real-time light effect of the original point source to be emulated.
Step S120, setting a local reflection probe at a preset position in the game scene.
The local reflection probe is used for collecting reflection data of light received by the self-luminous object. For a partial reflection probe (reflection probe), it can be understood as a reflection sphere in a game engine for simulating environmental reflection, which can collect reflection light data of the surrounding environment in real time, and can obtain reflection illumination data by baking the surrounding environment.
It should be noted that, the PBR material in the PBR material model refers to a material capable of implementing the whole rendering algorithm or process close to physical reality, and may also be understood as a material of an object surface capable of interacting with light in the real world. Illustratively, there are two situations where the light impinges on the surface of the object, either reflecting or continuing to refract. For example, for conductors, i.e. metals, the reflectivity is generally high, so that most of the light will bounce back in specular reflection and a small fraction will be completely absorbed after refraction. The reflection data of light in the embodiment of the present application refers to reflection data generated after light irradiates the PBR material model with smooth texture.
For example, the computer device may set a local partial reflection probe on an object (e.g., a PBR material model) that is locally affected by the original point source. For example, as shown in FIG. 3, the computer device may set a new blank partial reflection probe at a designated location in the game scene based on the position of the partial reflection probe and its parameters set by the game designer. The partial reflection probe may also be set to a baking (rake) mode in order to facilitate a subsequent baking process.
In this step, the computer device may set one or more local reflection probes in the game scene, and the local reflection probes can influence the model within a certain range around the local reflection probes.
Step S130, baking the PBR material model within the action range of the local reflection probe based on the reflection data to obtain reflection illumination data of the original point light source acting on the PBR material model.
Baking in the embodiment of the application refers to baking in advance the illumination map of the game scene before the game running by utilizing the illumination map (Lightmap) technology based on the calculated illumination, and the illumination map baked in advance can be directly used during the game running. The illumination map can record illumination brightness change based on a 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 local reflection probe in step S120, so as to implement the reflection data generated by the self-luminous object light collected by the local 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 the corresponding position of the model affected by the local reflection probe, and the metallic texture of the metal and the smooth object in the dark part can be more clearly represented by the highlight similar to the one generated by 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 simulation body of original pointolite produced to the PBR material model to embody comparatively true reflection effect, again will reflect data and bake in the reflection illumination data, can directly use this reflection illumination data when the recreation is operated, need not real-time calculation, can save the consumption of performance, thereby realized reducing the consumption of recreation operation when reducing comparatively true reflection effect.
The above steps are described in detail below.
In some embodiments, the self illumination of the original point light source can also be realized by baking, so that 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 overall illumination map.
As shown in fig. 4, the original point light source is also set to a baking (rake) 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. After the original real-time point light source is baked, the local brightness can be illuminated through the illumination map.
In this application embodiment, needs to bake whole recreation scene, makes original pointolite data by the illumination drawing gather, and self-luminous object is gathered by local reflection probe to this replaces the lightness of real-time light influence within-range article, and both play a role jointly, simulate the illumination and the reflection effect of real-time pointolite.
Through the baking of combining the original point light source with the baking of the reflection data, the illumination and reflection effects of the real-time point light source can be simulated under the conditions of lower running consumption and lower cost, the requirements of art can be met while the efficiency is optimized, and the efficiency and effects are met.
For example, as shown in fig. 5, conventional real-time computing illumination can embody a light source and a metal texture effect under real-time light, but has a large performance consumption; as shown in fig. 6, only the baking light is used, and the metallic effect of the partially reflected light cannot be shown under the baking light; as shown in fig. 7, by using the self-luminous object as a false light source and using the local reflection probe on the model to collect the reflected light generated by the self-luminous object, the reflected light data of the local reflection probe and the illumination data of the original point light source are baked, so that the illumination and reflection effects of the point light source can be increased, and the performance consumption is greatly reduced.
In some embodiments, multiple local reflection probes may be placed on several PBR material models that require reflection effects. As one example, the number of PBR material models is a plurality; at least one local reflection probe is arranged at the preset azimuth of each PBR material model.
Through a plurality of partial reflection probes, the PBR material model with the reflection effect is required to generate the reflection effect, and the generation position of the partial reflection effect in the whole game scene can be set according to the game requirement, so that the reflection effect is more flexible.
Based on this, the different levels of the partially reflective probe can be used to achieve the creation or absence of certain reflective effects. As an example, the preset azimuth of each PBR material model is provided with a plurality of local reflection probes; the plurality of local reflection probes corresponding to each PBR material model correspond to different reflection priorities; the step S130 may include the steps of:
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 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 exemplified as level 0 (lowest priority), level 1, level 2, and level 3 (highest priority), respectively. The local reflection probes with the reflection effect are determined according to the priority order of the reflection priority (namely the priority order of the reflection priority), namely the local reflection probes with the 3 levels (namely the target local reflection probes) are determined to be used preferentially, and the local reflection probes with the 0 level, the 1 level and the 2 level are not used first.
For step c) above, for example, baking may be performed based on the target reflection data corresponding to the reflection data of the stage 3 partial reflection probe (i.e., the target partial reflection probe) after step c) above.
In addition, the priority thereof may also be set in the position setting process of the partial reflection probe. For example, a local reflection probe is set to a model whose local area is originally affected by the original point light source, and the priority of this local reflection probe is increased, that is, the priority setting of the local reflection probe is increased (default to 0 before increasing), and the specific increased priority level may depend on the number of surrounding local reflection probes and the priority of display thereof.
In this embodiment of the present application, a plurality of local reflection probes may be nested through the multilayer of level, and whether the local reflection probe produces reflection influence to the PBR material model is set up to the priority level, for example, the high priority local reflection probe covers the low priority local reflection probe to realize setting up the reflection effect more nimble according to regional needs.
In some embodiments, the location of the partially reflective probe may be disposed directly above the PBR material model. As an example, the local reflection probe is arranged on top of the PBR material model. The computer equipment can put the local reflection probe according to the position above the PBR material model, so that the reflection data collected by the local reflection probe more accords with the actual situation 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 disposed at a central position on the PBR material model or a position determined according to an input operation. The preset position of the local reflection probe can be flexibly set by means of manual input operation or default of a system of the central position of the PBR material model and the like.
In some embodiments, the reflection intensity of the partially reflective probe may also be adjusted. As one example, the parameters of the partially reflective probe include reflected light intensity parameters. The reflection intensity of the local reflection probe can be flexibly adjusted and set according to the needs through the reflection light intensity parameter of the local reflection probe.
Of course, the setting can be flexibly adjusted in terms of the intensity, color and the like of the self-luminous object. As one example, the parameters of the self-luminous object include any one or more of the following: the method comprises the steps of collecting reflection data, namely self-luminous intensity parameters, self-luminous color parameters, self-luminous angle parameters and self-luminous angle parameters.
The self-luminous object can be more similar to the original point light source effect by adjusting specific self-luminous parameters of the self-luminous object, and the angle, intensity, color and the like of reflected high light 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 reflection probe.
In some embodiments, the self-luminous object may be used only for the baking process of the light map, without loading while the game is running. As one example, the tag of the self-luminous object is set to the edit-time display mode only. For example, a tag (tag) of a self-luminous object is set to be displayed only when editing (editor only), 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 needed local reflection probe.
In some embodiments, the position of the self-illuminating object may be set in the direction of the original point source relative to the partially reflective probe, which may also depend on the angle at which the highlights are desired to appear. As one example, the self-luminous object is disposed at an arbitrary position on the space line segment; the space line segment is a line segment formed between the original point light source and the local reflection probe. By arranging the self-luminous object on the line segment formed between the original point light source and the local reflection probe, the high light angle of the reflected light can be more appropriate, so that the reflected high light effect can be more vividly displayed.
Of course, the self-luminous object may also be arranged in other more specific exact positions. As one example, a self-luminous object is provided at an original point light source. The position of the self-luminous object is consistent with that of the original point light source, so that the high light effect of the reflected light can be more consistent with that of the original point light source in actual simulation.
As another example, the self-luminous object is disposed around the local reflection probe, for example, a self-luminous object is placed at a position closer to the local reflection probe in the above-mentioned space line segment, so that the local reflection probe can more efficiently collect the reflection data generated by the self-luminous object.
