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 invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for shadow processing of a virtual three-dimensional model, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
The method for processing the shadow of the virtual three-dimensional model in one embodiment of the disclosure can be operated on a terminal device or a server. The terminal device may be a local terminal device. When the shadow processing method of the virtual three-dimensional model runs on a server, the method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system comprises the server and a client device.
In an alternative embodiment, the terminal device may be a local terminal device. Taking a game as an example, the local terminal device stores a game program and is used for presenting a game screen. The local terminal device is used for interacting with the player through a graphical user interface, namely, a game program is downloaded and installed and operated through an electronic device conventionally. The manner in which the local terminal device provides the graphical user interface to the player may include a variety of ways, for example, it may be rendered for display on a display screen of the terminal or provided to the player through holographic projection. For example, the local terminal device may include a display screen for presenting a graphical user interface including a game screen and a processor for running the game, generating the graphical user interface, and controlling display of the graphical user interface on the display screen.
In the related art, the Shadow can be generated by a Shadow mapping (Shadow mapping) method, that is, all objects that can be seen from the light source position are in the light, and the objects behind the objects are in the Shadow. Another method for generating shadows is a Ray tracing (Ray tracing) method, which traces rays emitted from eyes instead of an external light source based on a special rendering algorithm in three-dimensional computer graphics, and has a more accurate simulation effect on reflection and refraction, so that the efficiency is very high, and a higher-quality effect can be realized. Fig. 1a is a schematic diagram of a Shadow processing method according to the related art, as shown in fig. 1a, a scene is rendered by using light of an engine, a surface depth of a visible object 12 is saved, a Shadow Map 11 (i.e., Shadow Map) is obtained, each point in a normal scene is compared with the Shadow Map 11, and whether each point in the scene can be seen by the light is judgedSo that the rendering of a normal scene is performed, point P in FIG. 1a is the point at which object 12 is shaded, and depth Z at which point P is locatedBGreater than the corresponding depth Z on the shadow map 11A. FIG. 1b is a schematic diagram of a shadow processing method according to the related art, in which when a point P is not a point at which an object 12 is shadowed, the point P is located at a depth Z as shown in FIG. 1bBEqual to the corresponding depth Z on the shadow map 11AAnd determining the shaded points in the scene according to the comparison between the depth of each point in the scene and the shadow map 11. The method can be applied to the manufacturing of the game scene, for example, the shadow of the plant is manufactured, the three-dimensional effect of the plant is enhanced, however, the shadow in the game scene is determined according to the shielding of the light, in the plant model with the higher number of faces, the shielding of the model on the light is richer, the precision of the shadow is higher, for the plant model with the lower number of faces, the shielding of the light is simpler, the precision of the shadow is poorer, and the three-dimensional effect of the scene is poorer.
In view of the above problem, according to an embodiment of the present invention, there is provided a method for processing a shadow of a virtual three-dimensional model, and fig. 2 is a flowchart of the method for processing a shadow of a virtual three-dimensional model according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
step S202, obtaining shadow cast texture, wherein the shadow cast texture is a cast shadow generated by irradiating the first virtual three-dimensional model in the target area by using a virtual light source in the game scene.
The target area is an area in a game scene where a shadow needs to be made, the target area may include one or more first virtual three-dimensional models, and a plurality of corresponding shadow cast textures may be made corresponding to the plurality of first virtual three-dimensional models. For example, the first virtual three-dimensional model may be a plant three-dimensional model, the target area of the game scene may be an area (e.g., a forest area) including a plurality of plants, different plants correspond to different first virtual three-dimensional models so as to represent plants having different shapes in the game scene, and a plurality of shadow cast textures corresponding to different plant three-dimensional models may be obtained after the target area is illuminated with a virtual light source in the game scene.
The shadow cast texture may be produced by a preset game engine according to the first virtual three-dimensional model, for example, the preset game engine may be 3DSMAX software, the first virtual three-dimensional model may be irradiated by a virtual light source in the 3DSMAX software, and a cast shadow may be generated according to the shielding of the first virtual three-dimensional model from the illumination of the virtual light source.
Step S204, the shadow cast texture is set as a cast shadow generated by a second virtual three-dimensional model in the target area under the irradiation of a virtual light source, wherein the shape of the second virtual three-dimensional model is the same as that of the first virtual three-dimensional model, and the number of patches of the second virtual three-dimensional model is lower than that of the first virtual three-dimensional model.
Since the number of patches of the second virtual three-dimensional model is lower than that of the first virtual three-dimensional model, the first virtual three-dimensional model can be considered as a low-surface-number virtual three-dimensional model, and the second virtual three-dimensional model is considered as a high-surface-number virtual three-dimensional model. Due to the fact that the high-surface-number virtual three-dimensional model has rich sheltering on the irradiation of the virtual light source, the accuracy of the cast shadow obtained based on the irradiation of the virtual light source is high, the obtained shadow cast texture of the high-surface-number virtual three-dimensional model is used in the game scene with the low-surface-number virtual three-dimensional model, the shadow accuracy of the low-surface-number virtual three-dimensional model can be improved, and the stereoscopic impression of the low-surface-number virtual three-dimensional model is improved.
The same shape may be the same appearance structure of the second virtual three-dimensional model and the first virtual three-dimensional model, for example, the second virtual three-dimensional model may be a low-surface plant model in a game scene, the first virtual three-dimensional model may be a high-surface plant model, the shapes of the low-surface plant model and the high-surface plant model are the same, and the shapes of the low-surface plant model and the high-surface plant model may be the same, and the shapes of the branches and the stems may be the same, the number of branches and leaves may be the same, and the extending directions of the branches and the leaves may be the same, so that the appearances of the low-surface plant model and the high-surface plant model are the same.
In an alternative embodiment, fig. 3 is a schematic diagram of a shadow cast by a second virtual three-dimensional model according to an embodiment of the present invention, as shown in fig. 3, the second virtual three-dimensional model may be a low-surface plant model in a game scene, the first virtual three-dimensional model may be a high-surface plant model in the game scene, in a 3d sdma software interface, a virtual light source 31 may be disposed at an upper right corner position in fig. 3, the virtual light source emits parallel light to illuminate a target area 32, the target area 32 includes a plurality of low-surface plant models 33, and a shadow cast texture is obtained by casting a shadow on the ground of the target area 32 by illumination. Fig. 4 is a schematic diagram of shadow cast textures of a low-surface-count plant model according to an embodiment of the present invention, and as shown in fig. 4, the shadow cast textures 41 of the low-surface-count plant model are thinner and have a poor stereoscopic effect. The high-surface-number plant model can be irradiated by a virtual light source in a 3d max software interface to obtain a cast shadow, fig. 5 is a schematic diagram of shadow cast textures of the high-surface-number plant model according to the embodiment of the invention, as shown in fig. 5, the high-surface-number plant model has rich shielding of light beams, high-precision shadow cast textures 51 can be generated, the high-precision shadow cast textures 51 replace the shadow cast textures 41 of the low-surface-number plant model in fig. 4, the low-surface-number plant model can have high-precision shadow cast textures, and the stereoscopic impression of the low-surface-number plant model is improved.
In this embodiment, shadow cast textures are obtained, where the shadow cast textures are set as cast shadows generated by a first virtual three-dimensional model in a target region illuminated by a virtual light source in a game scene, and the shadow cast textures corresponding to a first virtual three-dimensional model with a high number of facets are separately manufactured and used for setting a second virtual three-dimensional model with a low number of facets, so that a visual effect that the second virtual three-dimensional model with a low number of facets has high-precision shadows is achieved, a stereoscopic impression of the second virtual three-dimensional model with a low number of facets is enhanced, visual experience of the game scene is further improved, and the technical problems of a plant model with a low number of facets and low shadow precision in the related art are solved.
In an alternative embodiment, obtaining shadow cast textures comprises: acquiring a first virtual three-dimensional model corresponding to a second virtual three-dimensional model; setting the first virtual three-dimensional model and the second virtual three-dimensional model at a target position in a target area; and controlling the virtual light source to irradiate the target position from the preset direction to obtain shadow cast textures.
The first virtual three-dimensional model is the virtual three-dimensional model which has the same structure as the second virtual three-dimensional model and is provided with more patches. It should be noted that a plurality of second virtual three-dimensional models may be set in the target area, different second virtual three-dimensional models may have different shapes, the obtained first virtual three-dimensional model corresponds to the original second virtual three-dimensional model one to one, and the obtained first virtual three-dimensional model is placed at the original position (i.e., the target position) of the second virtual three-dimensional model.
The first virtual three-dimensional model and the second virtual three-dimensional model can be placed on the target position at the same time, or the second virtual three-dimensional model can be placed first and then the first virtual three-dimensional model can be placed, and the placing sequence of the first virtual three-dimensional model and the second virtual three-dimensional model is not limited.
In an alternative embodiment, placing the first virtual three-dimensional model and the second virtual three-dimensional model at a target location within the target area comprises: the first virtual three-dimensional model and the second virtual three-dimensional model are set at the same position within the target region.
The first virtual three-dimensional model and the second virtual three-dimensional model are placed at the same position, and the same virtual light source is used for irradiation, so that shadow cast textures of the first virtual three-dimensional model can be obtained, namely, a shadow with higher precision can be obtained.
For example, the second virtual three-dimensional model may be a low-count vegetation model in a game scene, and the first virtual three-dimensional model may be a high-count vegetation model in a game scene, as shown in fig. 3, in the 3DSMAX software interface, a plurality of low-surface plant models 33 in the target area are expressed as plants with different shapes, the obtained high-surface plant models correspond to the original low-surface plant models 33 one by one, the high-surface plant model with the same shape is placed at the original positions of the low-surface plant models 33, the same virtual light source 31 is used for illumination, the shadow cast by the high-surface plant model can be obtained, because the low-surface plant model and the high-surface plant model are the same in shape and placement position, the obtained cast shadow of the high-surface plant model can be used for the low-surface plant model, so that the effect that the low-surface plant model has high-precision shadow in a game scene is realized.
In an alternative embodiment, a first virtual three-dimensional model with a high number of patches may be manufactured first, and a second virtual three-dimensional model with a low number of patches may be obtained by a topology face reduction method, where the second virtual three-dimensional model is only the reduced number of patches but has the same shape as the first virtual three-dimensional model. It should be noted that, because many engines and game environments limit the number of patches of the virtual three-dimensional model, especially the number of patches displayed on the same screen is strictly limited, the virtual model with rich modeling often has a huge number of patches, and cannot be directly used in the game, and needs to be used after the number of patches is reduced, so as to ensure the performance of the game.
As an alternative embodiment, controlling the virtual light source to illuminate the target position from a preset direction, and obtaining the shadow cast texture includes: controlling a virtual light source to irradiate a target position from a preset direction, and determining a partial patch for receiving a drop shadow in a first virtual three-dimensional model; and performing rendering-to-texture operation on the partial surface slice to obtain shadow cast texture.
The first virtual three-dimensional model is a virtual three-dimensional model with a high number of patches, due to the fact that the number of patches is high, the shielding degree of virtual light source illumination is rich, a part of patches in the first virtual three-dimensional model can receive projection, rendering to texture operation is carried out on the part of patches receiving the drop shadow, and shadow drop texture is extracted.
Fig. 6 is a schematic diagram of obtaining shadow cast textures through rendering according to an embodiment of the present invention, and as shown in fig. 6, the first virtual three-dimensional model may be a high-surface plant model, and in an interface of 3DSMAX software, a partial surface patch receiving a cast shadow may be selected, rendering to a texture may be performed, and baking and extracting shadow cast textures of the first virtual three-dimensional model may be achieved by adding an element CompleteMap (i.e., a complete map). Fig. 7 is a schematic diagram of rendering a shadow cast texture according to an embodiment of the invention, and as shown in fig. 7, the shadow cast texture of the high-surface plant model extracted by baking has a richer form and can be used to set the shadow of the low-surface plant model, compared with the shadow of the low-surface plant model.
As an alternative embodiment, the method for processing the shadow of the virtual three-dimensional model further includes: and adjusting the object attribute of the first virtual three-dimensional model to enable the first virtual three-dimensional model to be in an invisible state in the visual field range of the virtual camera in the game scene.
The virtual camera is used for determining the production visual angle of the virtual three-dimensional model, namely the visual angle of the virtual camera is the same as the visual angle seen by a user in a game scene. When the mapping shadow of the second virtual three-dimensional model is made, only the shadow cast texture of the first virtual three-dimensional model needs to be extracted, the first virtual three-dimensional model does not need to be seen in a game scene, and the object attribute of the first virtual three-dimensional model is adjusted to make the first virtual three-dimensional model invisible to the virtual camera.
For example, the second virtual three-dimensional model may be a low-surface plant model in a game scene, the first virtual three-dimensional model may be a high-surface plant model in a game scene, as shown in fig. 3, in a 3d max software interface, a plurality of low-surface plant models 33 in a target area are represented as plants with different shapes, high-surface plant models with the same shape are placed at original positions of the plurality of low-surface plant models 33, and are irradiated by the same virtual light source 31, so as to obtain a cast shadow of the high-surface plant model, fig. 8 is a schematic diagram of adjusting object attributes of the first virtual three-dimensional model according to an embodiment of the present invention, as shown in fig. 8, the high-surface plant model is only used for making a high-precision shadow cast texture, and does not need to show the high-surface plant model in the game scene, so as attributes of the high-surface plant model can be set, and (3) entering an object attribute interface of the high-surface plant model, deselecting a visible camera option, and keeping other options of rendering control unchanged to ensure that the high-surface plant model can normally cast shadows.
As an alternative embodiment, the method for processing the shadow of the virtual three-dimensional model further includes: and adjusting the object attribute of the second virtual three-dimensional model to cancel the drop shadow generated by the second virtual three-dimensional model under the irradiation of the virtual light source.
When the mapping shadow of the second virtual three-dimensional model is manufactured, the final display effect is the shadow casting texture of the first virtual three-dimensional model, the actual mapping shadow of the second virtual three-dimensional model does not need to be displayed, and the casting shadow generated by the second virtual three-dimensional model under the irradiation of the virtual light source can be cancelled by adjusting the object attribute of the second virtual three-dimensional model.
For example, the second virtual three-dimensional model may be a low-count plant model in a game scene, the first virtual three-dimensional model may be a high-count plant model in a game scene, fig. 9 is a schematic diagram of adjusting object properties of a second virtual three-dimensional model according to an embodiment of the invention, as shown in fig. 9, in the 3DSMAX software interface, because the shadow cast texture of the high-surface plant model is obtained and is used as the cast shadow of the low-surface plant model, the method can set the object attribute of the low-surface plant model, specifically, enter the 'object attribute' interface of the low-surface plant model, deselect the 'cast shadow' option, and keep the other options of 'render control' unchanged, so that the low-surface plant model is in a visible state in the visual field range of the virtual camera in the game scene, but the shadow baking is not carried out.
Through the steps, the projection shadows which are extracted by baking the second virtual three-dimensional model and the first virtual three-dimensional model are displayed in the visual angle of the virtual camera, the shadow of the second virtual three-dimensional model is not baked, and the first virtual three-dimensional model is invisible to the virtual camera, so that the shadow of the second virtual three-dimensional model with lower precision is replaced by the projection of the first virtual three-dimensional model with higher precision, and the stereoscopic impression of the second virtual three-dimensional model with lower patch number is enhanced.
As an alternative embodiment, shadow cast textures are obtained using a first game engine and multiplexed to a second game engine.
The first game engine may be configured to produce a first virtual three-dimensional model of a high patch count, and the second game engine may be configured to produce a virtual three-dimensional model of a low patch count. In an alternative embodiment, the first game engine may be 3d sma software, and the second game engine may be any one of the production environments such as Neox, unity, unireal, etc.
It should be noted that, by using the shadow cast texture of the first virtual three-dimensional model obtained by the first game engine, the second virtual three-dimensional model may be replaced in the first game engine itself, for example, by placing the first virtual three-dimensional model and the second virtual three-dimensional model at the same target position through the above steps, and by setting cancellation of the projection of the first virtual three-dimensional model to the virtual camera, and setting cancellation of the projection of the second virtual three-dimensional model, the shadow of the second virtual three-dimensional model may be replaced in the first game engine by using the cast shadow of the first virtual three-dimensional model. After the shadow of the first virtual three-dimensional model obtained by the first game engine is baked and extracted, the shadow of the second virtual three-dimensional model is replaced in the second game engine, so that the three-dimensional visual effect of the virtual three-dimensional model in various game engines is improved, and the method can be suitable for various different game engines.
Since most games (especially hand games) have high requirements on the performance of the game, the high requirements on the patch number of the model, for example, the high patch number, require a high-performance game terminal, and may cause the terminal to operate in a stuck state.
