In this embodiment, a cloud layer rendering method operating on the mobile terminal is provided, and fig. 2 is a flowchart of a cloud layer rendering method according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps:

step S21, acquiring texture information of a plurality of channels in a target map, wherein the target map is used for rendering a virtual cloud layer model;

the target map may be a preset map for rendering the virtual cloud layer model, and in an actual application scene, the target map may be a noise resource map previously made by an artist. The object map may contain multiple channels (e.g., RGB channels), and texture information may be stored in each of the multiple channels.

Step S22, generating a plurality of target cloud layer masks based on the texture information;

based on texture information of multiple channels in the target map, the multiple target cloud masks (masks) may be generated, which may be used to render a virtual cloud model.

Specifically, the generating of the plurality of target cloud layer masks based on the texture information further includes other method steps, which may refer to the further description of the embodiments of the present invention, and will not be described herein again.

Step S23, performing blending processing on the multiple target cloud layer masks to obtain a first cloud layer rendering result corresponding to the virtual cloud layer model.

The blending processing of the target cloud masks may be multiple blending calculations and/or multiple result processing of the target cloud masks, where a calculation object of each blending calculation may be a part or all of the target cloud masks, and a processing object of each result processing may be a calculation result of each blending calculation.

And mixing the target cloud layer masks to obtain a first cloud layer rendering result corresponding to the virtual cloud layer model. In an actual application scene, the first cloud layer rendering result can show a better cloud layer virtual reality effect.

Specifically, the step of performing blending processing on the multiple target cloud layer masks to obtain the first cloud layer rendering result corresponding to the virtual cloud layer model further includes other method steps, which may refer to the following further description of the embodiment of the present invention, and is not repeated herein.

In at least some embodiments of the present invention, by obtaining texture information of multiple channels in a target map, where the target map is used to render a virtual cloud layer model, generating multiple target cloud layer masks based on the texture information, and performing blending processing on the multiple target cloud layer masks, a first cloud layer rendering result corresponding to the virtual cloud layer model is obtained, so as to achieve a purpose of generating a cloud layer rendering result by performing blending processing on the multiple cloud layer masks based on the map texture information, thereby achieving a technical effect of performing more realistic cloud layer effect rendering at a lower cost, and further solving technical problems of high rendering cost and poor virtual reality effect of a rendering result of a cloud layer rendering method provided in the related art.

The above-described method of embodiments of the present invention is further described below.

Optionally, in the cloud layer rendering method, the plurality of channels include: the first color channel, the second color channel, and the third color channel, the texture information comprising: the virtual cloud layer model comprises a first noise texture, a second noise texture and a bottom shadow form texture corresponding to the virtual cloud layer model, wherein a first color channel is used for storing the first noise texture, a second color channel is used for storing the second noise texture, and a third color channel is used for storing the bottom shadow form texture.

The plurality of channels of the target map may include: the first color channel (e.g., R channel in RGB channel), the first color channel (e.g., G channel in RGB channel), and the first color channel (e.g., B channel in RGB channel).

The texture information may include the first noise texture, the second noise texture, and a bottom shadow shape texture corresponding to the virtual cloud model. The first noise texture and the second noise texture are different noise textures, and the richness of the cloud layer form can be enhanced through the two different noise textures, so that the cloud layer with an approximate shape is avoided. The bottom shadow state texture corresponding to the virtual cloud layer model can be used for rendering the shadow effect of the cloud layer, and the volume sense of the cloud layer model is increased so as to enhance the virtual reality.

For example, when rendering the Cloud effect Cloud01 in the virtual game scene a, a Perlin Noise algorithm, a frame Noise algorithm, and a Voronoi Noise algorithm may be used to generate two different Noise textures, denoted as Noise01 and Noise 02; it is also necessary to obtain the bottom Shadow morphological texture Shadow01 previously made by the artist.

Generating the resource texture Tax from the Noise texture Noise01, the Noise texture Noise02, and the bottom Shadow morphological texture Shadow01 may include: storing the Noise texture Noise01 into an R channel of a resource texture Tex; storing the Noise texture Noise02 into a G channel of a resource texture Tex; the bottom Shadow morphological texture Shadow01 is put into the B channel of the resource texture Tex.

Optionally, in step S22, generating a plurality of target cloud layer masks based on the texture information may include performing the steps of:

step S221, generating a plurality of initial cloud layer masks based on the texture information;

step S222, cloud layer mask calculation is performed on the plurality of initial cloud layer masks to obtain a plurality of target cloud layer masks.

Still taking the example of rendering the Cloud effect Cloud01 in the virtual game scene a as an example, based on the resource texture Tax, a plurality of initial Cloud masks may be generated, and a plurality of target Cloud masks may be further generated through Cloud mask calculation.

Optionally, in step S221, the plurality of initial cloud layer masks include: the generating of the plurality of initial cloud layer masks based on the texture information may comprise performing the steps of:

step S2211, generating a first initial cloud layer mask based on the bottom shadow morphological texture, wherein the first initial cloud layer mask is used for determining a bottom cloud layer of the virtual cloud layer model;

step S2212, a second initial cloud layer mask, a third initial cloud layer mask and a fourth initial cloud layer mask are generated based on the first noise texture and the second noise texture, where the second initial cloud layer mask is used to determine a main noise layer of the virtual cloud layer model, the third initial cloud layer mask is used to determine an additional noise layer of the virtual cloud layer model, and the fourth initial cloud layer mask is used to determine a light-receiving and coloring layer of the virtual cloud layer model.

When rendering the Cloud effect Cloud01 in virtual game scene a, based on the resource texture Tax, the following four initial Cloud masks may be generated: an Overcast Swirl mask (equivalent to the first initial cloud mask), a Main cloud mask (equivalent to the second initial cloud mask), a Variation cloud mask (equivalent to the third initial cloud mask), and a Shading cloud mask (equivalent to the fourth initial cloud mask).

Specifically, based on the bottom Shadow morphological texture Shadow01 in the texture resource Tex, an Overcast Swirl mask is generated. The Overcast Swirl mask is used to render the bottom cloud layer in the virtual cloud layer model.

Specifically, based on the Noise texture Noise01 and the Noise texture Noise02 in the texture resource Tex, a Main cloud mask, a Variation cloud mask and a Shading cloud mask are generated, wherein the Main cloud mask is a cloud Main Noise layer obtained by multiplying the Noise texture Noise01 and the Noise texture Noise02, the Variation cloud mask is an additional cloud Noise layer obtained by mapping the multiplication result of the Noise texture Noise01 and the Noise texture Noise02 to a numerical interval [0.5, 1], and the Shading cloud mask is a cloud light-receiving coloring layer obtained by shifting, multiplying and superimposing the Noise texture Noise01 and the Noise texture Noise02 according to the real-time illumination direction in the virtual game scene a.

It should be noted that the value interval corresponding to the Variation cloud mask is relatively smaller than that of the Main cloud mask, and can be used to render the softer effect of the virtual cloud model. The Shading cloud shade takes the influence of the real-time direction of illumination (capable of reflecting weather change) in the virtual game scene A on the cloud layer effect into consideration, and can be used for rendering the bottom self-Shading effect of the virtual cloud layer model influenced by the real-time illumination.

It should be noted that a more cluttered Noise pattern can be obtained by the Main Clouds mask generated by the Noise texture Noise01 and the Noise texture Noise02, and the Main Clouds mask can be used for simulating the cloud effect of "fluffy floccules" in a real scene. In addition, other cloud layer masks involved in the actual application scene can be further calculated according to the Main cloud masks.

It should be noted that the Shading Clouds mask is a mask generated based on Noise texture Noise01 and Noise texture Noise02 to simulate the cloud self-Shading effect, that is, the Shading relationship in the Shading Clouds mask is associated with the shape of the Noise texture. An Overcast Swirl mask is used to render the bottom cloud layer in the virtual cloud layer model, which may be an optional mask in the actual application scene. Fig. 3 is a schematic diagram of an optional mask obtaining process according to an embodiment of the present invention, and as shown in fig. 3, texture resources Tex (including Noise texture Noise01, Noise texture Noise02, and bottom Shadow shape texture Shadow01 stored in each channel of the texture resources Tex) for rendering Cloud effect Cloud01 may be obtained by presetting material resources in a game engine (here, UE 4).

Still as shown in fig. 3, in the default game engine, four initial Cloud masks for rendering the Cloud effect Cloud01 may be generated by multiplication, superposition, migration, and other functions: overcast Swirl mask, Main cloud mask, Variation cloud mask and Shading cloud mask.

It should be noted that, in the process of calculating and generating the four initial cloud layer masks, the textures in each channel of the texture resource Tex are independent and controllable, so that the diversity of the generated four initial cloud layer masks can be improved.

Optionally, in step S222, the plurality of target cloud layer masks comprise: the cloud layer mask calculation is performed on the plurality of initial cloud layer masks to obtain the plurality of target cloud layer masks, and the method comprises the following execution steps of:

step S2221, cloud layer mask calculation is carried out on the first initial cloud layer mask, the second initial cloud layer mask, the third initial cloud layer mask and the fourth initial cloud layer mask to obtain a first target cloud layer mask, a second target cloud layer mask, a third target cloud layer mask and a fourth target cloud layer mask;

the first target cloud layer mask is used for simulating the effect of the virtual cloud layer model that the self-shadow changes along with real-time illumination, the second target cloud layer mask is used for rendering the transparency of the virtual cloud layer model, the third target cloud layer mask is used for simulating the shielding of input illumination intensity when the virtual cloud layer model is a multilayer cloud, the fourth target cloud layer mask is used for transiting the boundary between the virtual cloud layer model and the virtual association model, and the virtual association model is a virtual model shielded by the virtual cloud layer model.

Still taking the example of rendering the Cloud effect Cloud01 in the virtual game scene a, Cloud mask calculation is performed on four initial Cloud masks, and four target Cloud masks can be obtained.

Fig. 4 is a schematic diagram of an alternative target cloud mask according to an embodiment of the invention. Based on the Shading Clouds Mask, a cloud Shading Mask (as shown in fig. 4) for simulating the effect of the virtual cloud model that the self-shadow follows the real-time illumination change can be calculated through a migration calculation function, and is marked as Mask1 (which is equivalent to the first target cloud Mask).

Fig. 5 is a schematic diagram of another alternative target cloud mask according to an embodiment of the invention. Based on the Main cloud Mask obtained by multiplying the Noise texture Noise01 and the Noise texture Noise02, a cloud transparency Mask (as shown in fig. 5) is determined, which is denoted as Mask2 (corresponding to the second target cloud Mask).

Fig. 6 is a schematic diagram of another alternative target cloud mask according to an embodiment of the invention. Based on the variance cloud Mask, the transparency Mask2 is remapped to a smaller value range, for example, the value range of the transparency Mask2 is [0, 1], the value of the transparency Mask2 is mapped to [0.5, 1], and a cloud soft shadow Mask (as shown in fig. 6) is obtained, which is denoted as Mask3 (corresponding to the third target cloud Mask).

Fig. 7 is a schematic diagram of another alternative target cloud mask according to an embodiment of the invention. Based on the Overcast Swirl Mask, a blend Mask (shown in fig. 7) that is not affected by the transparency Mask and is inverse to the transparency Mask is calculated as Mask4 (corresponding to the fourth target cloud Mask).

It should be noted that the specific process of cloud mask calculation described above may be a blending calculation based on part or all of the Overcast Swirl mask, the Main cloud mask, the Variation cloud mask, and the Shading cloud mask.

It should be noted that the above process of generating the Mask1, the Mask2, the Mask3 and the Mask4 based on the Overcast Swirl Mask, the Main cloud Mask, the Variation cloud Mask and the Shading cloud Mask is an optional calculation process, and does not limit the correspondence between the Overcast Swirl Mask, the Main cloud Mask, the Variation cloud Mask and the Shading cloud Mask and the Mask1, the Mask2, the Mask3 and the Mask4, and other calculation methods may be selected in practical application scenarios. Optionally, in step S23, the blending the plurality of target cloud layer masks to obtain the first cloud layer rendering result may include the following steps:

step S231, in response to the virtual cloud layer model being a single-layer cloud, performing blending processing on the first target cloud layer mask, the second target cloud layer mask, and the fourth target cloud layer mask based on a first illumination intensity to obtain a first cloud layer rendering result, where the first illumination intensity is an original illumination intensity.

The first illumination intensity is the original illumination intensity related to the real-time illumination condition of the scene when the virtual cloud layer model is manufactured in the actual application scene.

Still taking the example of rendering the Cloud effect Cloud01 in the virtual game scene a, when the Cloud model corresponding to the Cloud effect Cloud01 is a single-layer Cloud, the Mask1, the Mask2, and the Mask4 in the target Cloud Mask are mixed, and a corresponding single-layer Cloud rendering result (equivalent to the first Cloud rendering result) can be obtained.

Specifically, the output single-layer cloud rendering result may be represented by the output cloud layer coloring Mask c1, and the blending processing method for obtaining the output cloud layer coloring Mask c1 may be to perform blending calculation on the transparency Mask2 and the cloud layer coloring Mask1 by using the blending Mask4 as a coefficient, as shown in the following formula (1):

MaskC1 ═ Mask4 × Mask2+ (1-Mask4) × Mask1 formula (1)

In the above equation (1), Mask1, Mask2, and Mask4 in the target cloud Mask are associated with the original illumination intensity.

Optionally, in step S23, the blending the plurality of target cloud layer masks to obtain the first cloud layer rendering result may include the following steps:

step S232, in response to the fact that the virtual cloud layer model is a multilayer cloud, performing mixing processing on a first target cloud layer mask, a second target cloud layer mask and a fourth target cloud layer mask based on a first illumination intensity to obtain a first processing result, and performing mixing processing on the first target cloud layer mask, the second target cloud layer mask and the fourth target cloud layer mask based on a second illumination intensity to obtain a second processing result, wherein the first processing result is a rendering result of a top layer cloud with the highest height in the multilayer cloud, the second processing result is a rendering result of other layers of clouds except the top layer cloud in the multilayer cloud, the first illumination intensity is an original illumination intensity, and the second illumination intensity is determined by the first illumination intensity and a third target cloud layer mask;

in step S233, a first cloud layer rendering result is determined using the first processing result and the second processing result.

Still taking the example of rendering the Cloud effect Cloud01 in the virtual game scene a as an example, when the Cloud model corresponding to the Cloud effect Cloud01 is a two-layer Cloud, the calculation method of the MaskD1 (equivalent to the first processing result) output Cloud layer coloring of the higher Cloud layer in the two-layer Cloud may be as shown in the following formula (2):

MaskD1 ═ Mask4 × Mask2+ (1-Mask4) × Mask1 formula (2)

In the above equation (2), the masks 1, 2, and 4 in the target cloud Mask are associated with the original illumination intensity.

In the double-layer cloud, when the MaskD2 is calculated for the output cloud layer coloring of the lower cloud layer, the shading of the higher cloud layer on the illumination intensity needs to be considered. The original illumination intensity is multiplied by the cloud layer soft shadow Mask3 to obtain the input illumination intensity corresponding to the lower layer of cloud.

Based on the input illumination intensity corresponding to the lower cloud layer, the output cloud layer coloring MaskD2 (corresponding to the second processing result) of the lower cloud layer can be obtained by calculating according to the following formula (3):

MaskD2 ═ Mask4 × Mask2+ (1-Mask4) × Mask1 formula (3)

In the above equation (3), Mask1, Mask2, and Mask4 in the target cloud layer Mask are associated with the input illumination intensities corresponding to the lower layer cloud.

Fig. 8 is a diagram illustrating an alternative cloud rendering result according to an embodiment of the present invention. The output cloud layer coloring MaskD1 of the higher cloud layer and the output cloud layer coloring MaskD2 of the lower cloud layer are overlapped, so that a cloud layer rendering result of the double cloud layer can be obtained (as shown in fig. 8).

It is easy to notice that the light intensity is adjusted through the cloud layer soft shadow mask so as to simulate the shielding of a lower cloud layer by a higher cloud layer in a multi-layer cloud, and the virtual reality effect of the rendering result of the virtual cloud layer model can be enhanced.

Optionally, the cloud layer rendering method may further include the following steps:

step S24, generating a fifth target cloud layer mask by using the position of the light source, wherein the gray scale corresponding to the fifth target cloud layer mask is determined by the distance relative to the position of the light source;

step S25, calculating to obtain a third illumination intensity by adopting the first illumination intensity, the current illumination color and a fifth target cloud layer mask, wherein the first illumination intensity is the original illumination intensity;

in step S26, the first cloud layer rendering result is adjusted to a second cloud layer rendering result based on the third illumination intensity.

In an actual application scenario, the light source position may be a position of a light source (such as the sun, the moon, the stars, the luminous flyer, and the like) in a virtual game scenario. A circular gray-scale gradation Mask (the farther from the center of the circle, the stronger the gray scale) is generated with the position of the light source as the center of the circle, and the Mask5 (corresponding to the fifth target cloud layer Mask) is marked. The current illumination color may be a color of a light source in the virtual game scene. The first illumination intensity may be a raw illumination intensity of a light source in the virtual game scene. The real-time illumination intensity of the light source (corresponding to the third illumination intensity) can be calculated according to the first illumination intensity, the current illumination color and the circular gray scale gradation Mask 5.

Based on the third illumination intensity, the first cloud layer rendering result may be adjusted to a second cloud layer rendering result. When the first cloud layer rendering result is output cloud layer coloring of the virtual cloud layer model, the output cloud layer coloring may be multiplied by the third illumination intensity to obtain an adjusted output cloud layer coloring. Specifically, for example: in a certain virtual game scene, the circle center position of the circular mask MaskY is determined according to the position of the sun, and the circular mask MaskY can be generated by controlling the radius, the coloring intensity and the edge gray level threshold of the circular mask MaskY. The circular mask MaskY may be used to calculate the real-time illumination intensity of the sun in the virtual game scene. Adjusting a cloud layer rendering result in the virtual game scene through the real-time illumination intensity, wherein the visual representation of the adjusted cloud layer rendering result may be: the cloud layer near the sun has higher brightness, and the cloud layer farther away from the sun has lower brightness.

It is easy to note that the light source (including the light source position, the illumination color, etc.) in the virtual game scene may be changed in real time, and the light source information may be obtained in real time from a real-time weather system associated with the virtual game scene, so as to enhance the virtual display effect of cloud layer rendering. Through the circular gray level gradient shade, the effect of gradient illumination intensity can be displayed on the sky ball of the virtual game scene, and the volume sense in the coloring effect of the virtual cloud layer model is enhanced.

It should be noted that, by the method provided by the embodiment of the present invention, the cloud shadow effect can be increased by increasing the color rendering parameter of the Overcast Swirl mask, and the method is suitable for rendering the black cloud dense effect in the virtual game scene.

It is easy to note that, compared with the cloud layer rendering method provided by the related art, the method provided by the embodiment of the present invention requires less performance consumption for rendering the virtual cloud layer model based on one texture resource, and is convenient for application at the mobile end.
