Description

Map processing method and device, storage medium and electronic equipment

Technical Field

The present disclosure relates to the field of computer graphics technologies, and in particular, to a map processing method, a map processing apparatus, a computer-readable storage medium, and an electronic device.

Background

When a fog effect scene such as a virtual desert is made, a very large and real special effect such as a sand storm is usually required to be made. The analysis of the demands in the game scene shows that the sandstorm needs to receive illumination, is dynamic and needs to have strong sense of volume. However, current games on the market do not have the effect scheme of the required quality, and most of the effects are achieved by using special effect launching maps in order to save performance.

The sandstorm effect is simulated by the transparent special effect mapping with disturbance and movement emitted by the particle special effect system, although the consumption is low, the requirements of some projects with delicate art expression cannot be met. Specifically, since the manufacturing material algorithm itself has no relationship with the light source information, the edge light generated by the light irradiating the dust body cannot be seen. Secondly, because the dynamic effect of the wind sand needs to be considered, most of the transmitted maps rotate irregularly and randomly, so that the volume feeling is lost or the accurate volume feeling cannot be expressed. More importantly, because the map is used for simulating the sandstorm effect, the interior scene of the sandstorm does not exist, the expression of the sandstorm is not exquisite, the sandstorm cannot be integrated into the terrain, and only 'false' shadow can be made.

In view of the above, there is a need in the art to develop a new method and apparatus for processing a map.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and the like. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

The terms "a," "an," "the," and "said" are used in this specification to denote the presence of one or more elements/components/parts/etc.; the terms "comprising" and "having" are intended to be inclusive and mean that there may be additional elements/components/etc. other than the listed elements/components/etc.; the terms "first" and "second", etc. are used merely as labels, and are not limiting on the number of their objects.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.

When a fog effect scene such as a virtual desert is made, a very large and real special effect such as a sandstorm is generally required to be made. The analysis of the demands in the game scene shows that the sandstorm needs to receive illumination, is dynamic and needs to have strong sense of volume. However, current games on the market do not have the effect scheme of the required quality, and most of the effects are achieved by using special effect launching maps in order to save performance.

The sandstorm effect is simulated by the transparent special effect mapping with disturbance and movement emitted by the particle special effect system, although the consumption is low, the requirements of some projects with delicate art expression cannot be met.

Fig. 1 is a schematic diagram illustrating an effect of a particle effect system simulating a sandstorm effect in the related art, and as shown in fig. 1, since a manufacturing material algorithm itself has no relationship with light source information, edge light generated by light irradiating on a sandstorm cannot be seen.

Fig. 2 is a schematic diagram illustrating another effect of a particle special effect system in the related art for simulating a sandstorm effect, as shown in fig. 1, since a chartlet is used for simulating the sandstorm effect, there is no scene inside the sandstorm, the expression of the sandstorm is not fine and smooth, and the sandstorm cannot be merged into the terrain, and only a "false" shadow can be made.

In addition, because the dynamic effect of the wind sand needs to be considered, most of the transmitted maps rotate irregularly and randomly, so that the volume feeling is lost or the accurate volume feeling cannot be expressed.

Therefore, when a very large and real special effect such as a sand storm needs to be made in the process of making fog effect scenes such as a virtual desert, the sand storm needs to be capable of receiving illumination, dynamic and strong in volume sense. However, current games on the market do not have the effect scheme of the required quality, and most of the effects are achieved by using special effect launching maps in order to save performance.

In order to solve the problems in the related art, the disclosure provides a map processing method. Fig. 3 shows a flow chart of a map processing method, which, as shown in fig. 3, comprises at least the following steps:

and S310, obtaining a first map and a fog effect material, and mixing the first map and the fog effect material to generate a flocculent fog effect.

And S320, carrying out texture movement treatment on the flocculent fog effect to obtain a fluttering fog effect, and carrying out mixed treatment on the fluttering fog effect and the first map to obtain a wiredrawing state fog effect.

And S330, carrying out illumination offset treatment on the wiredrawing state fog effect to obtain a scattering fog effect, and carrying out light and shade level adjustment on the scattering fog effect to obtain a target fog effect.

In the exemplary embodiment of the disclosure, the characteristics of the dot matrix are fully exerted by the mixing treatment and the subsequent mixing treatment of the first map and the fog effect material, so that the texture expression of the fog effect has more volume feeling and layering feeling, and more real fog effect is brought under the premise of lower performance consumption. Furthermore, parameter adjustment in a plurality of new directions is added when texture moving processing, illumination offset processing and light and shade level adjustment are carried out on the fog effect, more expression possibilities are given to the fog effect, the application scene of the fog effect is enriched, and the method can be suitable for more game art style projects.

The respective steps of the map processing method will be described in detail below.

In step S310, a first map and a fog effect material are obtained, and the first map and the fog effect material are mixed to generate a flocculent fog effect.

In an exemplary embodiment of the present disclosure, the first map and the fog effect material may be obtained first.

In an alternative embodiment, fig. 4 shows a schematic flow chart of a method for obtaining a first map and a fog effect material, as shown in fig. 4, the method at least comprises the following steps: in step S410, a single patch model is obtained, and a material map of the single patch model is obtained.

Wherein, the single patch model may be a particle generated by a UE4 Engine (Unreal Engine 4).

It is worth to say that the particle only needs to emit one particle, and does not need to emit a plurality of particles, so as to solve the performance problem of too many particles on the premise of complex materials.

Further, the UE4 engine may be used to obtain a texture map of the single grain, i.e., the single patch model.

In step S420, a first map is obtained by synthesizing the material map, and the fog effect material is obtained.

A UE4 engine is used to synthesize a plurality of material maps with smaller volumes to obtain a 3D (3-dimensional) map, i.e., a first map.

Further, volume material of the UE4 engine is obtained as the fog effect material.

The volume material is a material type used by the volume fog, and can be used for making effects on a lattice (voxel) covering the scene overall. In addition, the volume of the map cloud and the map fog in the game can be increased, so that a more natural scattering picture can be obtained when light penetrates through the cloud fog.

In the exemplary embodiment, the corresponding first mapping can be acquired through a single patch model, the acquisition mode is simple and accurate, and a mapping basis is provided for subsequent invalid generation.

After the first map and the fog effect material are obtained, the first map and the fog effect material can be mixed.

In an alternative embodiment, fig. 5 shows a flow diagram of a method of mixing processing, as shown in fig. 5, the method at least comprising the steps of: in step S510, the first map and the fog effect material are mixed to obtain an original fog effect, and a second map is obtained.

Specifically, the spatial coordinate relationship stored in the first map can be used, and the lattice generated by the fog effect material is expressed in a world space coordinate system, so that the transparent and opaque ranges of the cloud and fog in the world space are identified, and the original fog effect is obtained.

Further, in order to perform superposition processing on the original fog effect, a second map can be obtained. The second map is a different map from the first map.

In step S520, the second map and the original fog effect are superimposed to obtain a block fog effect, and a third map is obtained.

After the world space coordinate system is acquired, the first map may be tiled multiple times, for example 256 times, within the world space coordinate system, and then the first map after being tiled multiple times may be randomly shifted by a constant. The second map is then reduced by a factor of 16 or other factors to increase the degree of repetition. Further, the first mapping after random offset and the second mapping after reduction are input into the lattice information of the fog effect material, so that the material function is processed to obtain the block fog effect.

Although the block-like fogging has been mixed 2 times, the problem of the degree of repetition that is the appearance effect of the light and dark appearance divided by the grid is not solved, and therefore, a third map may be further acquired to continue the superimposition processing using the third map.

It is noted that the third map is a map with more texture details.

In step S530, the third map and the block fog effect are superimposed to obtain a flocculent fog effect.

Specifically, the spatial coordinate relationship stored in the third map may be utilized, and the dot matrix generated by the fog effect material is represented in the world space coordinate system, so as to further mark the transparent and opaque ranges of the cloud and fog in the world space, thereby obtaining the flocculent fog effect.

Moreover, since the superposition processing and the mixing processing are performed in the same manner, the superposition processing is also performed in the same manner as the superposition processing in step S520, and thus, the description thereof is omitted.

In this exemplary embodiment, the first, second, and third maps are used to perform three times of continuous mixing processing on the fog effect material to obtain the flocculent fog effect, so that the detail expression is improved from the light and shade division angle, and the flocculent effect which is the same as the fog effect in reality appears compared with the original fog effect and the massive fog effect, and the fog effect is better in expression.

In step S320, the texture moving process is performed on the flocculent mist effect to obtain a fluttering mist effect, and the fluttering mist effect and the first map are mixed to obtain a wiredrawing mist effect.

In an exemplary embodiment of the present disclosure, after obtaining the fog effect of the cloud, the fog effect of the cloud may be subjected to a texture moving process.

Specifically, the captured time attribute in the UE4 engine is used to move the world coordinate position captured during the previous mixing operation, so that the flocculent fog effect is moved to obtain the fluttering fog effect. The time attribute is an attribute built into the UE4 engine and is a value that can be increased as game time grows.

Where texture moves can be merged by defining 3 attributes. These three attributes are timeoffset, DensityTextureA _ moving, and winDRI, respectively. Timeoffset expresses time offset control, DensityTextureA _ moving defines the speed of cloud layer flutter, and winDRI expresses the direction of flutter.

However, the cloud or dust in real life is not one piece but slightly in a state of being drawn. Therefore, in order to achieve the cloud mist in the real state, the first paste can be used to add a layer of displacement effect, namely time staggered feeling, on the fluttering mist effect so as to obtain the wire-drawing mist effect.

Specifically, the fluttering fog effect can be expressed in a world space coordinate system in a form of a dot matrix generated by the fog effect material by using a spatial coordinate relationship stored in the first map, and the fluttering fog effect is staggered with the previous fog effect to obtain the wiredrawing state fog effect.

Moreover, since the blending process here corresponds to the superimposition process performed again by using the first map, the blending process is also the same as the superimposition process in step S520, and is not described again here.

In addition, the second map or the third map may be used for the mixing process.

In an alternative embodiment, the fluttering fog effect and the second map are mixed to obtain the wiredrawing fog effect.

Specifically, the fluttering fog effect can be expressed in a world space coordinate system in a form of a dot matrix generated by the fog effect material by using a space coordinate relationship stored in the second map, and the fluttering fog effect is staggered with the previous fog effect to obtain the wiredrawing fog effect.

Moreover, since the blending process here corresponds to the second overlay process performed again by using the second map, the blending process is also the same as the process of the overlay process in step S520, and is not described again here.

In an alternative embodiment, the fluttering fog effect and the third sticking chart are mixed to obtain the wiredrawing state fog effect.

Specifically, the fluttering fog effect can be expressed in a world space coordinate system in a form of a dot matrix generated by the fog effect material by using a space coordinate relationship stored in the third map, and the fluttering fog effect is staggered with the previous fog effect to obtain the wiredrawing state fog effect.

Further, since the mixing process here corresponds to the superimposition process performed again by the third tile, the mixing process is also the same as the superimposition process in step S520, and is not described again here.

In the present exemplary embodiment, in order to obtain the mist effect in the string state, the first, second, or third maps may be mixed with the fluttering mist effect, and the map of the mixed process is a previously used map, so that the consumption of performance is not caused. In addition, any one of the three used maps can be selected according to the desired effect of the wiredrawing state, so that various selection and generation effects are provided for the mixing treatment.

In step S330, the light offset processing is performed on the drawn-wire fog effect to obtain a scattering fog effect, and the light and shade gradation adjustment is performed on the scattering fog effect to obtain a target fog effect.

In exemplary embodiments of the present disclosure, after obtaining the wiredrawing haze effect, the wiredrawing haze effect may be subjected to an illumination offset process.

In an alternative embodiment, fig. 6 shows a flow diagram of a method of illumination shift processing, as shown in fig. 6, the method at least comprising the steps of: in step S610, the illumination direction corresponding to the wiredrawing state fog effect is determined, and the wiredrawing state fog effect is copied to obtain a backup fog effect.

The illumination direction may be an illumination direction of captured parallel light in the engine of the UE4, or other illumination directions may be set according to actual situations, which is not particularly limited in this exemplary embodiment.

Further, the obtained wiredrawing state fog effect is copied to be used as a backup fog effect.

In step S620, offset processing is performed on the backup fog effect according to the illumination direction to obtain an offset fog effect, and brightness adjustment processing is performed on the offset fog effect to obtain a brightness fog effect, so as to determine the wire-drawing fog effect and the brightness fog effect as scattering fog effects.

In an alternative embodiment, fig. 7 shows a flow diagram of a method of brightness adjustment processing, which, as shown in fig. 7, at least comprises the following steps: in step S710, the backup fog effect is shifted according to the illumination direction to obtain a shifted fog effect, and the shifted fog effect is increased in brightness to obtain a brightness fog effect.

And shifting the copied backup fog effect to a certain degree towards the illumination direction to obtain the shifted fog effect. Specifically, the offset mist effect may be moved above the mist effect in the string state.

Further, the brightness of the offset fog effect is adjusted so that the brightness of the offset fog effect is increased to obtain the brightness fog effect.

In step S720, offset processing is performed on the backup fog effect in the opposite direction of the illumination direction to obtain an offset fog effect, and brightness reduction processing is performed on the offset fog effect to obtain a brightness fog effect.

And shifting the copied backup fog effect to the opposite direction of the illumination direction to a certain degree to obtain the shifted fog effect. Specifically, the offset mist effect may be moved to a position below the mist effect in the string state.

Further, the brightness of the offset fogging effect is adjusted so that the brightness of the offset fogging effect is reduced to obtain the brightness fogging effect.

In the exemplary embodiment, differential offset processing and brightness adjustment processing are performed on the backup fog effect according to the illumination direction to obtain the corresponding brightness fog effect, the processing mode is simple and accurate, the display of the fog effect is linked with the light source information and is consistent with the real scene, the edge light effect generated by the light on the fog effect is obtained, and the vividness and the reality of the brightness fog effect are increased.

After the lightness haze effect is obtained, the lightness haze effect and the wire-drawing state haze effect can be used as scattering haze effects to present a scattering state.

After the scattering fog effect is obtained, the light and shade gradation of the scattering fog effect can be adjusted.

In an alternative embodiment, fig. 8 shows a flow chart of a method for adjusting a shading level, and as shown in fig. 8, the method at least includes the following steps: in step S810, the scattering fog effect and the first map are mixed to obtain a mixed fog effect, and a self-luminous map is obtained.

Specifically, the mixed fog effect can be obtained by expressing the scattering fog effect in a world space coordinate system in a lattice form generated by the fog effect material by using a spatial coordinate relationship stored in the first map.

Further, a self-luminous map can be obtained.

The self-luminous map (Emissive) can control the color and brightness of light emitted by the surface. When the self-luminous map is used in the scene, the scene looks like a visible light, and the surface of the object also has the self-luminous effect.

In step S820, the light and shade gradation of the mixed fog effect and the self-luminous map is adjusted to obtain a target fog effect.

Specifically, a position which is lower than the mixed fog effect on a world space coordinate system is obtained, all spaces of the lower position are controlled to be lightened through the self-luminous map, and the brightening effect can be that partial areas are lightened and partial areas are not lightened. That is, the transparent part of the mixed fog effect can be brightened through the self-luminous map at the lower layer, and the part with low transparency can not be brightened or can not be brightened through the self-luminous map to a certain extent, so that the visual brightening effect is achieved, and the target fog effect is obtained.

In the exemplary embodiment, the light and shade gradation of the scattering fog effect is adjusted through the first map and the self-luminous map to obtain the corresponding target fog effect, so that the target fog effect is presented with more volume feeling and gradation feeling, and the effect of cloud and fog or dust can be more truly presented. In addition, the target fog effect has more expression possibilities, and provides basis for the subsequent display of more game art styles.

In addition, the adjustment of the light and shade gradation of the scattering fog effect can be realized through a second map and a third map.

In an alternative embodiment, fig. 9 shows a flow chart of another method for adjusting a shading level, and as shown in fig. 9, the method at least includes the following steps: in step S910, the scattering fog effect and the second map are mixed to obtain a mixed fog effect, and a self-luminous map is obtained.

Specifically, the mixed fog effect can be obtained by expressing the scattering fog effect in a world space coordinate system in a lattice form generated by the fog effect material by using a space coordinate relationship stored in the second map.

Further, a self-luminous map can be obtained. The self-luminous map can control the color and brightness of light emitted by the surface. When the self-luminous map is used in the scene, the scene looks like a visible light, and the surface of the object also has the self-luminous effect.

In step S920, the light and shade gradation of the mixed fog effect and the self-luminous map is adjusted to obtain a target fog effect.

In the exemplary embodiment, the light and shade gradation of the scattering fog effect is adjusted through the second map and the self-luminous map to obtain the corresponding target fog effect, so that the target fog effect is presented with more volume sense and gradation sense, and the effect of cloud and fog or dust can be more truly presented. In addition, the target fog effect has more expression possibilities, and provides basis for the subsequent display of more game art styles.

In an alternative embodiment, fig. 10 shows a flow chart of another method for adjusting a shading level, and as shown in fig. 10, the method at least includes the following steps: in step S1010, the scattering fog effect and the third map are mixed to obtain a mixed fog effect, and a self-luminous map is obtained.

Specifically, the mixed fog effect can be obtained by expressing the scattering fog effect in a world space coordinate system in a form of a dot matrix generated by the fog effect material by using a spatial coordinate relationship stored in the third map.

In step S1020, the light and shade gradation of the mixed fog effect and the self-luminous map is adjusted to obtain a target fog effect.

In the exemplary embodiment, the scattering fog effect is subjected to light and shade level adjustment through the third map and the self-luminous map to obtain the corresponding target fog effect, so that the target fog effect is presented more volumetrically and hierarchically, and the cloud fog or dust effect can be more truly presented. In addition, the target fog effect has more expression possibilities, and provides basis for the subsequent display of more game art styles.

The following describes the mapping processing method in the embodiment of the present disclosure in detail with reference to an application scenario.

Fig. 11 is an interface diagram illustrating a method for obtaining a first mapping in an application scenario, and as shown in fig. 11, a single patch model is obtained, and a material mapping of the single patch model is obtained.

Wherein a single patch model may be a particle generated by the UE4 engine emission.

And synthesizing the material map to obtain a first map.

A UE4 engine is used to synthesize a plurality of material maps with smaller volumes to obtain a 3D map, i.e. a first map.

Fig. 12 is a schematic diagram illustrating an effect of an original fog effect generated in an application scenario, and as shown in fig. 12, a volume material owned by a UE4 engine is further obtained as the fog effect material.

Obviously, the surface of the fog effect material has no light and shade division, and the original fog effect can present more obvious light and shade division after being mixed with the first map.

However, the repeatability of the original fog effect at the present stage, that is, the light and shade division is too obvious as being divided by the grid, is still too high, so that a layer of 3D map can be superimposed to eliminate the too high repeatability.

In order to perform superposition processing on the original fog effect, a second mapping can be obtained. The second map is a different map from the first map.

And the second mapping and the original fog effect are superposed to obtain the block fog effect.

Specifically, after the world space coordinate system is acquired, the first map may be tiled multiple times, for example 256 times, in the world space coordinate system, and then the first map after being tiled multiple times may be randomly shifted by a constant. The second map is then reduced by a factor of 16 or other factors to increase the degree of repetition. Further, the first mapping after random offset and the second mapping after reduction are input into the lattice information of the fog effect material, so that the material function is processed to obtain the block fog effect.

Fig. 13 is a schematic diagram illustrating the effect of the block fog effect in an application scenario, and as shown in fig. 13, the block fog effect has been mixed for 2 times, but the problem of too high repetition degree is not solved, so a third map may be further obtained to continue the overlay processing using the third map.

Fig. 14 is a schematic diagram illustrating the effect of the flocculent fog effect obtained by superimposing a third tile in the application scene, where the third tile is a tile with more detailed texture, as shown in fig. 14.

And superposing the third mapping and the block fog effect to obtain the flocculent fog effect.

Compared with the massive fog effect, the flocculent fog effect can show a flocculent effect closer to the reality.

Further, the basic information of the flocculent fog effect can be controlled by more parameters in the UE4 engine.

The method for controlling the parameters of the flocculent fog effect in the application scene can be that the superposition repetition degree and the brightness of the flocculent fog effect are specified by the two parameters. Each layer is increased by 2 more parameters, so that after three times of mixing, 6 more parameters are increased.

The control of the repetition degree can be realized by a tilting parameter, and the brightness can be realized by a parameter of the fineness degree of the texture. Further, since the brightness is related to the height of the fogging effect, the control can be performed by adding a parameter of the height of the fogging effect.

Because the flocculent fog effect is more like a white cloud at the present stage, the flocculent fog effect can be further subjected to texture moving treatment in order to make the flocculent fog effect move.

The texture moving method in the application scene may be to use the time attribute in the captured UE4 engine to move the world coordinate position captured during the previous mixing operation, so that the flocculent fog effect is moved to obtain the fluttering fog effect. The time attribute is an attribute built into the UE4 engine and is a value that can be increased as game time grows.

Of course, the cloud or dust in real life is not one piece, but has a little stringing state. Therefore, in order to achieve the cloud mist in the real state, the previous paste can be used to add a layer of replacement effect, namely time staggered feeling, on the fluttering mist effect so as to obtain the wire-drawing mist effect.

Because the cloud mist is fake at the same moving speed, the moving speed of each layer of the fluttering mist effect needs to capture the original world coordinate position, and then a 3D map is mixed to set different time, so that the cloud mist effect and the previous mist effect are staggered to form the wire-drawing state mist effect in the wire-drawing state.

It should be noted that the mixed 3D map may be any one of the first map, the second map, or the third map that has been used before, and may be determined according to a desired drawing state, and since the map that has been used before is used, no performance consumption is caused.

Or the fluttering fog effect can be expressed in a world space coordinate system in a form of a dot matrix generated by the fog effect material by utilizing a space coordinate relation stored in the second map, and the fluttering fog effect is staggered with the previous fog effect to obtain the wiredrawing state fog effect.

And the fluttering fog effect can be expressed in a world space coordinate system in a form of a dot matrix generated by the fog effect material by utilizing a space coordinate relation stored in the third map, and the fluttering fog effect is staggered with the previous fog effect to obtain the wire-drawing fog effect.

Fig. 15 is a schematic diagram illustrating the effect of the mist effect in the wire-drawing state in an application scenario, and as shown in fig. 15, a layer of replacement effect is added by the mixing treatment of the fluttering mist effect and the first map, so that the fluttering mist effect in the original state of being "false" shows the wire-drawing state.

Further, in order to overcome the problem of the volume feeling of the most difficult cloud or dust, the method can be overcome from the aspects of illumination expression and layering expression.

The method of determining the illumination direction in the application scenario may be to grab the illumination direction of the parallel light inside the engine with the UE4 engine.

The method for obtaining the brightness fog effect corresponding to the wiredrawing state fog effect in the application scene can be that the obtained wiredrawing state fog effect is firstly copied to be used as the backup fog effect.

And then, carrying out offset processing on the backup fog effect according to the illumination direction to obtain an offset fog effect, and carrying out brightness adjustment processing on the offset fog effect to obtain a brightness fog effect.

Firstly, offset processing is carried out on the backup fog effect according to the illumination direction to obtain an offset fog effect, and brightness increasing processing is carried out on the offset fog effect to obtain a brightness fog effect.

And secondly, carrying out offset processing on the backup fog effect according to the opposite direction of the illumination direction to obtain an offset fog effect, and carrying out brightness reduction processing on the offset fog effect to obtain a brightness fog effect.

After the lightness haze is obtained, the lightness haze and the wire-drawing haze can be used as scattering haze.

Fig. 16 is a schematic diagram illustrating the effect of the scattering fog effect in an application scenario, and as shown in fig. 16, the scattering fog effect can simulate edge light refracted by the cloud fog when the cloud fog is irradiated by light, so as to present a scattering effect.

The light and shade gradation adjustment method in the application scene can be used for mixing the scattering fog effect and the first map to obtain a mixed fog effect and acquiring a self-luminous map.

Further, a self-luminous map can be obtained.

The self-luminous map can control the color and brightness of light emitted by the surface. When the self-luminous map is used in the scene, the scene looks like a visible light, and the surface of the object also has the self-luminous effect.

And adjusting the light and shade levels of the mixed fog effect and the self-luminous map to obtain the target fog effect.

And mixing the scattering fog effect and the second mapping to obtain a mixed fog effect, and obtaining a self-luminous mapping.

And mixing the scattering fog effect and the third pasting picture to obtain a mixed fog effect, and obtaining a self-luminous pasting picture.

Further, a self-luminous map can be obtained.

Fig. 17 is a schematic diagram illustrating the effect of the target fog effect in an application scene, and as shown in fig. 17, a pure black area is the target fog effect, and a white area is a self-luminous map effect which shines through, so that the target fog effect is more layered through the transmission effect of the self-luminous map.

Fig. 18 is a schematic diagram illustrating an effect of a sandstorm effect generated in an application scenario, and as shown in fig. 18, after a target fog effect is generated, parameters such as sensitivity, complexity, offset, cloud color, and the like of the target fog effect can be finely adjusted according to actual requirements, so that a final sandstorm expression effect can be obtained.

Fig. 19 is a comparison graph of the dust effect generated according to the particle special effect emission map and the dust effect generated by the method of the present disclosure, and as shown in fig. 19, the transparent special effect map with disturbance and movement is emitted by the particle special effect system to simulate the sand storm effect, although the consumption is low, the transparent special effect map cannot meet the project requirements of more exquisite art performance. Specifically, since the manufacturing material algorithm itself has no relationship with the light source information, the edge light generated by the light irradiating the dust body cannot be seen. Secondly, because the dynamic effect of the wind sand needs to be considered, most of the transmitted maps rotate irregularly and randomly, so that the volume feeling is lost or the accurate volume feeling cannot be expressed. More importantly, because the map is used for simulating the sandstorm effect, the interior scene of the sandstorm does not exist, the expression of the sandstorm is not exquisite, the sandstorm cannot be integrated into the terrain, and only 'false' shadow can be made.

However, the sand effect generated according to the method disclosed by the invention fully exerts the dot matrix characteristic used in multiple mixing treatment, so that the sand effect has more volume and hierarchy senses, and the effect of more real sand storm is realized. In addition, a plurality of adjustment parameters in a new direction are added in the process of charting, so that the dust can have more expression possibility and can be suitable for more game art-style items. The method is also a mode for expressing more real dust effect on the premise of not consuming excessive performance.

Fig. 20 is a schematic diagram illustrating an interface using the method for processing a tile according to the present disclosure in an application scenario, and as shown in fig. 20, different 3D tiles can be produced according to requirements of different game art styles. For example, when making a cloud, since the cloud is soft, there is no need for very small black and white pieces of 3D mapping; when making dust, then the black and white blocks that need the 3D map are denser.

Further, the generated 3D patch may be used to replace the previous patch contained in the UE4 engine and applied to the niagara system to launch a particle.

Where the Niagara module has been added to the engine's plug-in the latest UE4 engine. When the method is needed, only a plug window is opened through the menu Edit- > plug, Niagara is searched, and Enable is selected. Clicking on the right mouse button in the Content Browser then causes a new menu option FX to appear, which includes the various resource options of the Niagara system. Among the various resources included in the Niagara System, the Niagara System is a particle System resource, the Niagara Emitter is a transmitter resource, the Niagara Script is a particle System logic Script resource, and the Niagara Parameter Collection is a Parameter set resource.

The Niagara System resource is similar to the Particle System resource in Cascade. The creation mode can be created through a right-click menu 'FX- > Niagara System', when the Niagara System is dragged into a scene, the engine automatically creates a Niagara Actor and refers to the Niagara System resource in the Niagara Component. Double clicking on the Niagara System resource opens the editor for editing.

The Niagara system provides an editing mode similar to that of the BluePrint, so that the particle system is more convenient and flexible to manufacture. The particle emitter can be controlled, and meanwhile, the particles can be controlled by a user, so that the motion state of the particles can be customized by the user, and a more complex particle special effect can be manufactured.

Fig. 21 is a schematic diagram of an interface for adjusting parameters in an application scenario, and as shown in fig. 21, after a particle is transmitted on the niagara system, parameters to be adjusted may be specified and adjusted on a parameter table of a shader (material). And finally, applying the shader to the particle material emitted by the niagara system to obtain the target fog effect.

Wherein the object when presented comprises, in addition to the body, an inherent color and texture. Texture also determines what material the object is made of.

Based on this, when the effect of cloud or dust is achieved by using the special effect emission map in the related art, because the manufacturing material algorithm and the light source information do not have any relation, the edge light generated by the light irradiating on the dust cannot be seen. Secondly, because the dynamic effect of the wind sand needs to be considered, most of the transmitted maps rotate irregularly and randomly, so that the volume feeling is lost or the accurate volume feeling cannot be expressed. More importantly, because the map is used for simulating the sandstorm effect, the interior scene of the sandstorm does not exist, the expression of the sandstorm is not exquisite, the sandstorm cannot be integrated into the terrain, and only 'false' shadow can be made.

In the chartlet processing method in the exemplary embodiment of the disclosure, the characteristics of the dot matrix are fully exerted by the mixing processing and the subsequent mixing processing of the first chartlet and the fog effect material, so that the texture expression of the fog effect has more volume feeling and layering feeling, and more real fog effect is brought on the premise of lower performance consumption. And on the aspect of sand and dust effect expression, the landform can be blended, so that the sand and dust expression is more exquisite. Furthermore, parameter adjustment in a plurality of new directions is added when texture moving processing, illumination offset processing and light and shade level adjustment are carried out on the fog effect, more expression possibilities are given to the fog effect, the application scene of the fog effect is enriched, and the method can be suitable for more game art style projects.
