Description

Technical Field

[0001] This application relates to the field of game technologies, and particularly to a method and apparatus for rendering hairstyles in a game scene, an electronic device, and a storage medium. Background Art

[0002] In order to enrich more personalized gameplay for players and enhance the differentiation of products, in the case where functions such as face pinching and beauty makeup are already very common, the concept of hairstyle design has been proposed in games. The currently commonly used method is to perform hairstyle design through a digital haircut simulator. This solution performs fine procedural modeling on the hair, abstracts each part of the hair into detail units, and can perform plasticity and trimming in multiple modes for each detail unit. However, if the current game is a multiplayer online game, using a digital haircut simulator for hairstyle design will result in a too high Draw Call (a type of command in the command buffer), a too large data storage volume, and thus a too low frame rate and a large network transmission pressure.

[0027] The following will describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application.

[0028] The embodiments of the present application provide a method for rendering a hairstyle in a game scene, as Figure 1 shown, the steps of the method include:

[0029] Step 102, in response to a hairstyle selection operation for the virtual character, determine the hairstyle partition parameters and texture map channel parameters in the hairstyle selection operation;

[0030] Step 104: Determine the target hairstyle area of the virtual character and the target channel in the target hairstyle texture map corresponding to the target hairstyle area according to the hairstyle partition parameters and texture map channel parameters. Among them, the hairstyle texture maps stored in different channels of the target hairstyle texture map correspond to different hairstyle lengths in the target hairstyle area;

[0031] Step 106: Render the target hairstyle area of the virtual character according to the hairstyle texture map stored in the target channel.

[0032] Through the above steps 102 to 106, the target hairstyle area of the virtual character and the target channel in the target hairstyle texture map corresponding to the target hairstyle area can be determined according to the hairstyle partition parameters and texture map channel parameters. Furthermore, the target hairstyle area of the virtual character can be rendered according to the hairstyle texture map stored in the target channel, that is, the target hairstyle area of the virtual character can be directly rendered according to the hairstyle partition parameters and texture map channel parameters. The personalized requirements for hairstyles in the game can be achieved without procedural modeling, and the data transmission can be completed with a lower latency in a multi-player online game, thus solving the problem in the prior art that the data storage volume is large when building hairstyles through procedural modeling, resulting in data transmission latency.

[0033] In an optional implementation manner of the present application, for the method of rendering the target hairstyle area of the virtual character according to the hairstyle texture map stored in the target channel involved in the above step 106, it may further include:

[0034] Step 11: When the target channel is a preset channel, perform texture sampling on the hairstyle texture map stored in the target channel and the solid color texture map corresponding to the target hairstyle area respectively according to the first set of texture coordinates corresponding to the target hairstyle area to obtain a first sampling result and a second sampling result;

[0035] Step 12: Render the target hairstyle area of the virtual character based on the first sampling result and the second sampling result;

[0036] Step 13: When the target channel is a non-preset channel, perform texture sampling on the hairstyle texture map stored in the target channel and the solid color texture map corresponding to the target hairstyle area respectively according to the second set of texture coordinates corresponding to the target hairstyle area to obtain a third sampling result and a fourth sampling result;

[0037] Step 14: Render the target hairstyle area of the virtual character based on the third sampling result and the fourth sampling result.

[0038] It should be noted that in a specific example, the preset channel in the embodiments of the present application may be the A channel of the alpha map (target hairstyle map), rather than other channels of the alpha map except the A channel. There can be four channels for the alpha map; the map in the A channel is the initial hairstyle, and the corresponding hairstyle length is the longest (compared with the hairstyle lengths corresponding to other channels), and the solid color map may refer to the Base color map. In addition, different hairstyle regions correspond to different texture coordinate values in the same texture coordinate. Moreover, since the hairstyle lengths of the hairstyle maps stored in different channels are different, after determining the channel in the hairstyle map corresponding to the hairstyle region, a second set of texture coordinates is required to perform texture sampling on the hairstyle map stored in the target channel and the solid color map corresponding to the hairstyle region, and then rendering is performed. That is, when the player cuts the hair (that is, when choosing to use a non-preset channel), sampling based on the second set of texture coordinates adapted to the currently selected channel can make the finally rendered hair effect more natural; that is to say, the hairstyle length of the same hairstyle region can be controlled through different channels in the hairstyle map, without the need to programatically model multiple prefabricated hairstyles to achieve the change of the hairstyle length, reducing the data transmission delay.

[0039] In another alternative implementation manner of the embodiments of the present application, after the method of rendering the target hairstyle region of the virtual character involved in step 106, the method of the embodiments of the present application may further include:

[0040] Step 21, obtain the input adjustment parameter;

[0041] Step 22, adjust the length of the hairstyle in the hairstyle map in the target channel based on the adjustment parameter;

[0042] Step 23, render the target hairstyle region of the virtual character based on the adjusted hairstyle map.

[0043] As can be seen from the above steps 21 to 23, after rendering the target hairstyle area of the virtual character according to the hairstyle texture map stored in the target channel, so that the target hairstyle area is rendered into the hairstyle length corresponding to the hairstyle texture map, the hairstyle texture map can be further stretched based on the adjustment parameter to achieve a fine adjustment of the hairstyle length. In a specific example, based on the control code in the Shader, the preset Alpha map (hairstyle texture map) can be stretched in the V direction (i.e., the vertical direction) to achieve arbitrary adjustment of the hairstyle length. Specifically, based on this control code, the values stored in the Alpha map representing transparency are set. For example, the value 0 represents completely transparent, and the value 1 represents opaque. Then, if you want to lengthen the hairstyle, you can control the code to stretch the non-transparent area in the vertical direction according to the adjustment parameter. For example, set the pixel points that were originally 0 in the vertical direction to 1, that is, change the original transparent area in the vertical direction to opaque to increase the hairstyle length; conversely, the effect of shortening the hairstyle can be achieved, that is, control the code to shorten the non-transparent area in the vertical direction according to the adjustment parameter. For example, set the pixel points that were originally 1 in the vertical direction to 0, that is, change the original opaque area in the vertical direction to transparent to shorten the hairstyle length and achieve the effect of hair cutting; specifically, whether to lengthen or shorten the hairstyle length is controlled by the adjustment parameter input by the user, that is, the player.

[0044] In addition, the method of rendering the target hairstyle area of the virtual character based on the adjusted hairstyle texture map is similar to the above steps 11 to 14, that is, texture sampling is performed on the hairstyle texture map stored in the target channel and the solid color texture map corresponding to the target hairstyle area according to the second set of texture coordinates corresponding to the target hairstyle area to obtain the corresponding sampling results, and then the target hairstyle area of the virtual character is rendered again based on the sampling results, so that the finally rendered hair effect can be more natural.

[0045] In another optional implementation manner of the embodiment of the present application, before determining the target hairstyle area of the virtual character and the target channel in the target hairstyle map corresponding to the target hairstyle area according to the hairstyle partition parameter and the texture map channel parameter involved in step 104, the method in the embodiment of the present application further includes:

[0046] Step 31, mapping the initial second set of texture coordinates of each hairstyle area of the hairstyle model to the corresponding hairstyle area in the target texture space to obtain the second set of texture coordinates of each hairstyle area in the texture space, where part or all of the texture coordinate values of the second set of texture coordinates of each hairstyle area in the texture space are not between 0 and 1;

[0047] Step 32: Scale the second set of texture coordinates of each hairstyle area in the texture space to obtain the scaled second set of texture coordinates corresponding to each hairstyle area.

[0048] Based on the above Step 31 and Step 32, the partitioning of the hairstyle model of the virtual character in the target texture space can be achieved, and the scaled second set of texture coordinates corresponding to each hairstyle partition can be obtained, thus providing a basis for subsequently adjusting the hairstyle lengths of each hairstyle partition respectively. Taking the initial second set of texture coordinates as (x, y) as an example, the second set of texture coordinates OffsetUV in the texture space is OffsetUV = (OffsetX + X, OffsetY + Y); that is to say, the above mapping is actually an offset, that is, the initial second set of texture coordinates is offset to this target texture space, and OffsetX and OffsetY are the offset values in the U and V directions when the initial texture coordinates are offset to the corresponding hairstyle area in the target texture space. In a specific example, the scaled texture UV = OffsetUV / 3.0. Further, in the specific example, the hairstyle area may include a preset hairstyle area and a non-preset hairstyle area. Among them, the preset hairstyle area is the area that supports adjusting the hairstyle length, and the non-preset hairstyle area is the area that does not support adjusting the hairstyle length. The hairstyles in the preset hairstyle area may include at least one of the following: bangs, right-back hair, middle-back hair, left-back hair, left sideburn, and right sideburn.

[0049] Based on the above Steps 31 to 32, in an alternative implementation manner of the embodiments of the present application, the method steps of the embodiments of the present application may further include:

[0050] Step 41: Map according to the scaled second set of texture coordinates corresponding to the target hairstyle area to obtain the second set of texture coordinates for texture sampling of the hairstyle texture map stored in the target channel and the solid color texture map corresponding to the target hairstyle area, where the second set of texture coordinates for texture sampling is between 0 and 1.

[0051] For the above Step 41, taking the hairstyles of the set hairstyle area as bangs, right-back hair, middle-back hair, left-back hair, left sideburn, and right sideburn as an example, as Figure 2 shown, the numerical values of the second set of texture coordinates of different areas of the hairstyle model are respectively distributed in different areas of the target texture space, that is, each hairstyle area is respectively mapped to 9 texture spaces in the target texture space, and the texture coordinates of the hairstyle model are expanded to different hair partitions. The second set of texture coordinates UV for texture sampling: RenderUV = (3.0 * scaled UV.x - [scaled UV.x], 3.0 * scaled UV.y - [scaled UV.y]), where [] represents taking the integer; scaled UV.x represents the x coordinate in the scaled UV coordinates, and scaled UV.y represents the y coordinate in the scaled UV coordinates.

[0052] In an alternative implementation manner of the embodiment of the present application, for the manner of determining the target hairstyle area of the virtual character and the target channel in the target hairstyle texture map corresponding to the target hairstyle area according to the hairstyle partition parameter and the texture map channel parameter involved in step 104 above, it may further include:

[0053] Step 51, determine the target hairstyle area characterized by the hairstyle partition parameter;

[0054] Step 52, when the target hairstyle area is a preset hairstyle area, determine the target hairstyle texture map corresponding to the target hairstyle area;

[0055] Step 53, determine the target channel in the target hairstyle texture map corresponding to the texture map channel parameter according to the texture map channel parameter.

[0056] Among them, the texture map channel parameter can be selected according to the different hairstyle lengths of the user, that is, the player, for the target hairstyle area, and this texture map channel parameter is used to represent a specific channel in the target hairstyle texture map.

[0057] For the manner of determining the target hairstyle area characterized by the hairstyle partition parameter in steps 51 to 53 above, in a specific example, the area of the hairstyle to be adjusted can be determined through pseudocode. Specifically, it can be: determine the corresponding partition index according to the hairstyle partition parameter, and determine the corresponding hairstyle area according to this partition index. Among them, the hairstyle partition parameter can be the second set of texture coordinates after scaling of this area. For example, if the lengths of the ponytail and sideburns are to be adjusted, the pseudocode is as follows:

[0058] int index = GetUVIndex()

[0059] switch (index)

[0060] {

[0061] case 1 return ponytail

[0062] case 2 return sideburns

[0063] }

[0064] The above pseudocode is only an example and can be set accordingly according to requirements. In addition, if the currently determined area is not the area to be trimmed, the hairstyle texture map and the solid color texture map stored in the preset channel in the Alpha texture map corresponding to this area can be directly texture sampled through the first set of texture coordinates, and then rendered to obtain the final hairstyle.

[0065] Through the hair rendering method in the game scene of the embodiments of the present application, the hair can be divided into six regions: bangs, left ponytail, right ponytail, middle of the ponytail, left temple, and right temple, and the length data of these six regions are stored respectively, reducing the latency of real-time transmission. Moreover, without modifying the prefabricated hairstyle model, the transparency of the hair is modified through a Shader to achieve hair clipping, as Figure 3 shown. The left side is before clipping, and the right side is after clipping. It can be seen that in the embodiments of the present application, the rendering can be accelerated through the Instance drawing technique, and there is no need to use procedural modeling to produce a variety of prefabricated hairstyles to achieve changes in hairstyle length, improving the efficiency of hair rendering.

[0066] Corresponding to the above Figure 1 , the embodiments of the present application also provide a hair rendering device in a game scene, as Figure 4 shown. The device includes:
