Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. 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.
In the related art, three methods for drawing the makeup of the character exist, the first method is to adopt Skinned dacal as a bottom layer technology, and dynamically draw contents on a model of the bone skin animation through contents stored in a chartlet, namely, adding the chartlet to the model of the bone skin animation, but the method does not achieve the effect of mixing multiple layers of graphs and has low drawing precision. The second is a common makeup drawing mode in online games, which synthesizes a map or directly switches maps during operation, but the degree of freedom for a player to perform custom drawing on a virtual character is poor. The third is to use the function of a cosmetic pen of the figure correcting software to draw, but the function can only correct the makeup in a two-dimensional space, and cannot be directly applied to a three-dimensional model in a game, so that the function is difficult to be applied to a three-dimensional virtual character in the game.
Based on the above problems, embodiments of the present invention provide a method, an apparatus, and an electronic device for drawing makeup in games, which can be applied to scenes for drawing makeup of characters in games, especially scenes for drawing makeup of characters in hand games.
In order to facilitate understanding of the embodiment of the present invention, a method for drawing makeup in a game disclosed in the embodiment of the present invention is first described in detail, and the method is applied to a terminal device, which may be a mobile terminal (e.g., a mobile phone, a tablet computer, a notebook computer, etc.) or a computer; providing a graphical user interface through terminal equipment, wherein the graphical user interface at least comprises a virtual character, and the virtual character comprises a three-dimensional character model and a map covered on the surface of the three-dimensional character model; as shown in fig. 1, the method comprises the steps of:
and step S102, responding to the makeup drawing triggering operation aiming at the virtual character, and determining the target makeup to be drawn and the tool parameters of the drawing tool required for drawing the target makeup.
In the game, the virtual character is a three-dimensional character model, the surface of the three-dimensional character model is covered with maps, and each map is corresponding to a corresponding color. The target makeup comprises eye makeup, eyebrows, eye shadows, blush, a beauty pupil, lipstick and the like, wherein each target makeup is provided with a corresponding button in a graphical user interface, and a player can trigger the button corresponding to the target makeup to be drawn so as to draw the target makeup to be drawn.
The tool parameters of the drawing tool required for drawing the target makeup comprise one or more of color, size, shape and hardness of the target tool; the drawing tool may be displayed in a graphical user interface as a virtual brush or a virtual pointer, etc. In a specific implementation, when a player triggers a button of a target makeup to be drawn in a graphical user interface, a plurality of selection buttons of tool parameters of a tool for drawing the target makeup corresponding to the button can be displayed in the graphical user interface, the drawing color corresponding to each selection button is different, and the player can trigger the selection button corresponding to the color to be drawn according to requirements to complete setting of the tool parameters of the tool for drawing, namely, the tool parameters are set to the color corresponding to the triggered button.
In step S104, a target drawing area is determined in response to movement of the drawing tool on the virtual character.
The player can select the drawing tool and drag the drawing tool to move on the virtual character, at this time, a preset script at a Central Processing Unit (CPU) in the electronic device records an input operation of the player and converts the input operation of the player into a drawing instruction, so that the drawing tool is controlled to move on the virtual character through the drawing instruction, the position of the drawing tool in the map of the virtual character is recorded in the moving process, and the target drawing area is generated according to the position where the drawing tool passes.
And step S106, updating the chartlet of the target drawing area according to the tool parameters of the drawing tool to obtain the drawing result of the target makeup.
In specific implementation, the map of the target drawing area can be updated according to the tool parameters of the drawing tool, and the updated map of the target drawing area is used for adjusting the map of the target makeup to obtain the drawing result of the target makeup. For example, when the tool parameter of the drawing tool is the designated color, the color of the map of the target drawing area is updated to the designated color, and the overlapping area of the map of the target makeup look and the map of the target drawing area is replaced by the overlapping area of the map of the target makeup look and the target makeup look in the target drawing area after the color update, so that the map of the target makeup look after the color update, that is, the drawing result of the target makeup look is obtained.
After the drawing result of the target makeup is obtained, the drawing result is displayed in a chartlet area of the target makeup in the graphical user interface so as to be convenient for a player to watch, whether the drawing result is the effect wanted by the player or not is confirmed, and if the drawing result is not the effect wanted by the player, the target makeup can be drawn continuously through the drawing tool.
The dressing drawing method in the game provided by the embodiment of the invention comprises the steps of firstly responding to a dressing drawing trigger operation aiming at a virtual character, determining a target dressing to be drawn and drawing tool parameters of a drawing tool required by the target dressing, wherein the virtual character comprises a three-dimensional character model and a map covering the surface of the three-dimensional character model; further responding to the movement of the drawing tool on the virtual character, and determining a target drawing area; and then updating the chartlet of the target drawing area according to the tool parameters of the drawing tool to obtain the drawing result of the target makeup. In the method, the virtual character of the three-dimensional character model is drawn by the drawing tool, and the drawing tool can freely move on the virtual character according to the requirement of a player, so that the freedom degree of the player for custom drawing of the virtual character is improved, and the drawing precision can also be improved.
The embodiment of the invention also provides another makeup drawing method in a game, which is realized on the basis of the embodiment, and the method mainly describes a specific process of determining a target drawing area in response to the movement of a drawing tool on a virtual character (specifically realized by the following steps S204-S208); as shown in fig. 2, the method comprises the steps of:
step S202, responding to the makeup drawing triggering operation aiming at the virtual character, determining the target makeup needing to be drawn and the tool parameters of the drawing tool needed for drawing the target makeup.
And step S204, responding to the touch starting operation acted on the drawing tool, and recording the current position of the drawing tool on the virtual character.
The touch start operation of the drawing tool may be an operation in which the player starts to trigger the drawing tool, and the touch start operation of the drawing tool may also be understood as an operation in which the drawing tool is dropped. In a specific implementation, when a player is at a PC (Personal Computer), the touch start operation of the drawing tool may be an operation in which the player clicks the drawing tool in a graphical user interface through a mouse; when a player is at a mobile terminal (e.g., a mobile phone, a tablet computer, etc.) with a touch function, the touch start operation of the drawing tool may be an operation in which the player presses the drawing tool displayed on the screen with a finger or a stylus.
When a trigger starting operation acting on the drawing tool is received, the current position of the drawing tool in the virtual role needs to be recorded immediately so as to conveniently record the passing position of the drawing tool on the virtual role and determine a target drawing area.
And step S206, responding to the movement operation acted on the drawing tool, controlling the drawing tool to move from the current position, and recording the position of the drawing tool on the virtual character in the moving process.
The above-described moving operation on the drawing tool may be an operation in which the player draws on the virtual character, and the moving operation of the drawing tool may also be understood as an operation in which the drawing tool is in a state of being drawn. In a specific implementation, when a player is at the PC, the moving operation of the drawing tool may be an operation in which the player drags the drawing tool to move on a virtual character after clicking the drawing tool in the graphical user interface through a mouse; when the player is at the moving end having the touch function, the moving operation of the drawing tool may be an operation in which the player presses the drawing tool with a mobile phone or by touch longer than the moving end and drags the drawing tool to move on the virtual character.
According to the moving operation, the position of the drawing tool on the virtual character can be adjusted, that is, the drawing tool is controlled to move from the current position, and each time the drawing tool moves one position, the position of one drawing tool on the virtual character is recorded, so that each position passed by the drawing tool in the drawing is obtained.
In a specific implementation, the step of recording the position of the drawing tool on the virtual character during the moving process includes: and recording the position of the drawing tool on the virtual character through a preset virtual camera in the moving process of the drawing tool. The virtual camera is set in the electronic device in advance, when the drawing tool starts to move or after the drawing tool moves for a certain distance, the virtual camera is called through a preset script, and each position which the drawing tool passes through in the moving process is recorded (or shot) through the virtual camera, so that each position is colored subsequently.
The certain distance of the movement of the drawing tool is set by research personnel in advance, and the certain distance can be set to be a smaller numerical value, such as a few pixel points or a few tenths of millimeters. After the drawing tool moves for a certain distance, the position of the drawing tool on the virtual character is recorded, and some invalid operations can be filtered out, for example, a player clicks the drawing tool carelessly and triggers the movement operation, but the movement distance is short, so that the drawing tool is regarded as invalid operation, and the position is not recorded, so that some unnecessary memories can be saved.
In step S208, in response to the touch end operation applied to the drawing tool, the movement of the drawing tool is stopped, and the position where the drawing tool passes from the current position is determined as the target drawing area.
The touch end operation of the drawing tool may be an operation in which the player ends the touch of the drawing tool, and the touch end operation of the drawing tool may also be understood as an operation in which the drawing tool is lifted. In a specific implementation, when the player is at the PC, the touch termination operation of the drawing tool may be an operation in which the player stops clicking the drawing tool in the graphical user interface through a mouse; when the player is at the moving end having the touch function, the touch termination operation of the drawing tool may be an operation in which the player lifts and presses a finger or a stylus pen in the drawing tool.
When receiving a trigger end operation acting on the drawing tool, ending the movement of the drawing tool in the virtual character, and obtaining a target drawing area, wherein the target drawing area comprises a position through which the drawing tool passes from the current position to the end of the movement.
And step S210, updating the chartlet of the target drawing area according to the tool parameters of the drawing tool to obtain the drawing result of the target makeup.
Before the step S210, the resolution of the target makeup picture in the virtual character map may be set to a preset first resolution; setting the resolution of the maps of the virtual character, except the map of the target makeup, as a preset second resolution; wherein the first resolution is higher than the second resolution.
In a specific implementation, the resolution of the target makeup map in the virtual character map is set to a first higher resolution, and the resolution of the maps except the target makeup map in the virtual character map is set to a second lower resolution, so that the virtual character map can achieve high local precision by using a smaller map, for example, the resolution of the global map of the virtual character is 1024, and in order to achieve high detail, 128 × 128 or 256 × 256 maps can be separately assigned to the target makeup map (eyebrow, lip, etc.), and another set of texture coordinates is used for separate mapping, so that the local map (the target makeup map) achieves an effect which can be achieved only when the resolution of the global map is close to 4096.
The detail map may also be referred to as a detail map or a second level map, i.e. to allow overlaying of a second set of textures on top of the original map. In particular implementations, the resolution of the target makeup tile is set to a first resolution, which is equivalent to overlaying a second texture on the virtual character's tile, such that the target makeup tile has clear details when viewed at close range and normal levels of detail when viewed at distance, without the need to use a very tall virtual character's global tile to accomplish both goals. Therefore, different areas are set to different resolutions, and high mapping precision can be achieved under the condition that less memory is used.
The makeup drawing method in the game comprises the steps of firstly responding to makeup drawing triggering operation aiming at a virtual character, determining a target makeup to be drawn and tool parameters of a drawing tool required for drawing the target makeup; further responding to touch starting operation acted on the drawing tool, and recording the current position of the drawing tool on the virtual character; then responding to the moving operation acted on the drawing tool, controlling the drawing tool to move from the current position, and recording the position of the drawing tool on the virtual role in the moving process; responding to touch control ending operation acting on the drawing tool, stopping the movement of the drawing tool, and determining the position where the drawing tool passes from the current position as a target drawing area; and then updating the chartlet of the target drawing area according to the tool parameters of the drawing tool to obtain the drawing result of the target makeup. According to the method, the drawing tool can be controlled to freely move on the virtual character according to the requirements of the player, and the player can freely draw the target makeup, so that highly personalized custom drawing can be realized, the makeup experience in reality can be more approximate, and the game immersion and game experience of the player are increased.
The embodiment of the invention also provides another makeup drawing method in a game, which is realized on the basis of the embodiment, and the method mainly describes a specific process of updating the chartlet of the target drawing area according to the tool parameters of the drawing tool to obtain the drawing result of the target makeup (specifically realized by the following steps S306-S310); as shown in fig. 3, the method comprises the steps of:
step S302, responding to the makeup drawing triggering operation aiming at the virtual character, determining the target makeup needing to be drawn and the tool parameters of the drawing tool needed for drawing the target makeup.
In step S304, a target drawing area is determined in response to movement of the drawing tool on the virtual character.
Step S306, sending the target rendering region and the tool parameters of the rendering tool to the GPU.
The GPU (graphics Processing Unit) may also be called a display core, a visual processor, and a display chip, and is generally a microprocessor specially used for performing operations related to images and graphics on a terminal device.
And step S308, coloring the map of the target drawing area through the GPU based on the tool parameters of the drawing tool to obtain the colored map of the target drawing area.
After receiving the target rendering area and the tool parameters of the rendering tool, the GPU renders the target rendering area in a rendering Texture (Render Texture, abbreviated as RT) according to the tool parameters of the rendering tool, that is, performs shading processing on the target rendering area by using a shader (shader) in the Render Texture to obtain a shading map of the target rendering area, where the Render Texture is usually a special type Texture created and updated during runtime, and can Render a three-dimensional model in a game.
The GPU can be used for improving the image processing speed of the CPU, coloring a target drawing area in the GPU and rendering a drawing tool, so that the drawing speed can be improved; and when the number of the surfaces of the three-dimensional character model of the virtual character is large, the CPU running in the mobile terminal such as a mobile phone and the like is difficult to support a large amount of calculation, so that the performance overhead of the CPU can be reduced by using the GPU, the mobile terminal can be ensured to run in real time, and the drawing efficiency is improved. In a specific implementation, the three-dimensional character model is generally composed of one small triangle, and each small triangle is used for running one surface in the party feather three-dimensional character model, so that the number of the surfaces of the three-dimensional character model is large, and the number of the small triangles is also large.
In a specific implementation, the tool parameters of the drawing tool include the type of the drawing tool; the rendering map of the target rendering area is obtained by the GPU through the following steps 10-12:
and step 10, determining a map of the drawing tool based on the type of the drawing tool.
The drawing tool may be one or more of a color, a size, a hardness, and a shape, and is set according to development requirements, and is not particularly limited herein. Specifically, different mapping of the drawing tool can be obtained according to different combinations of colors, sizes, hardness and shapes and different setting contents corresponding to various types in each combination. For example, the color of the drawing tool is red, the size of the drawing tool is 10 × 10, and the shape of the drawing tool is circular, and a map with the color of red, the size of 10 × 10, and the shape of circle can be automatically obtained according to the settings, and the map is the map of the drawing tool.
And 11, mixing the mapping of the drawing tool with preset blue noise to obtain the coloring intensity of the drawing tool.
The above blue noise is generally referred to as uniformly distributed random unbiased noise. And mixing a blue noise with the mapping of the drawing tool to obtain the coloring intensity of the drawing tool, and avoiding the phenomenon of generating a hard edge when the coloring intensity is used for drawing the target drawing area. Meanwhile, the blue noise can reduce color bands (color banding) in the map and can also make the edge of the map softer.
And step 12, coloring the map of the target drawing area based on the coloring intensity.
In some embodiments, in order to achieve the effect of image softening, after the map of the drawing tool is mixed with the preset blue noise to obtain the coloring intensity of the drawing tool, the coloring intensity of the drawing tool needs to be subjected to gaussian blurring to obtain a final coloring intensity, and then the map of the target drawing area is colored by the final coloring intensity. The gaussian blur processing may be implemented by a shader.
The above gaussian blurring process, which may also be referred to as a gaussian smoothing process, can reduce image noise and reduce the level of detail. The visual effect of the image generated by the blurring technique is like observing the image through a frosted glass, which is obviously different from the out-of-focus imaging effect of a lens and the effect in a common lighting shadow.
In a specific implementation, the step 12 can be implemented by the following steps 20 to 21:
and step 20, determining the color drawing range of the drawing tool according to the coloring intensity, the color of the chartlet of the target drawing area before drawing, the image mask corresponding to the target makeup and the preset color of the final chartlet.
The color of the map of the target rendering region before the rendering is obtained by: responding to a touch starting instruction of a drawing tool, and recording a current map of the virtual character; and determining the current color of the map of the target drawing area from the current map, and determining the current color as the color of the map of the target drawing area before drawing. It is also understood that when the player starts drawing, the map of the virtual character at the present time (corresponding to the above-described present map) is recorded, and then the map of the target drawing area, and the color thereof, are determined from the present map. Specifically, the color of the map of the target rendering region includes the color of each pixel point in the map of the target rendering region.
The tool parameters of the drawing tool at least comprise the color of the drawing tool; the color of the final map is determined by: determining the color of the drawing tool as the color of the final map; or determining a final map from a plurality of preset maps according to the tool parameters to determine the color of the final map; wherein each preset map corresponds to a tool parameter.
The tool parameters of the drawing tool can include hardness, size or shape and the like besides color, the drawing tools with different types of tool parameters correspond to different preset maps, and the corresponding relation between each preset map and the tool parameters is set in advance, so that the final map and the color of the final map can be determined from a plurality of preset maps according to the tool parameters. In some embodiments, the color of the drawing tool may also be determined directly as the color of the final map. The color of the final map includes the color of each pixel in the final map.
The image Mask corresponding to the target makeup is also the Mask of the drawable area corresponding to the target makeup to be drawn, the Mask is provided by the art and used for calibrating the drawable area, for example, when blush is drawn, the art provides a Mask for marking the drawable blush area, and under the condition that the mobile phone is not easy to operate and control, for example, a mobile phone platform screen is small and difficult to accurately operate and control, the Mask provided by the art can control and limit the drawn boundary, the maximum color depth and the like, so that the final drawing quality of a player is ensured.
And step 21, coloring the mapping of the target drawing area according to the coloring intensity and the color drawing range of the drawing tool.
In the process of drawing, the obtained drawing intensity and the obtained color drawing range of the drawing tool are used for coloring the chartlet of the target drawing area, so that the colored chartlet with better visual viewing effect can be obtained.
The color drawing range of the drawing tool is set, so that the phenomenon that the drawing tool draws too deep color at one stroke in the drawing process can be prevented, and the drawing effect can be improved. In a specific implementation, the step 20 can be implemented by the following steps 30 to 32:
and step 30, determining the color of the mapping of the target drawing area before drawing as the minimum value of the color drawing range of the drawing tool.
And step 31, subtracting the color of the map of the target drawing area before drawing from the color of the final map to obtain a color difference value.
And step 32, determining the product of the color difference value and the image mask and the coloring intensity as well as the sum of the colors of the mapping of the target drawing area before drawing as the maximum value of the color drawing range of the drawing tool.
Specifically, assuming that the color of the map of the target drawing area before drawing is O, the color of the final map is T, the image mask corresponding to the target makeup is M, and the coloring intensity of the drawing tool is I, the color drawing range of the drawing tool is [ O, O + M (T-O) × I ].
Step S310, determining the overlapping area of the map of the target makeup and the coloring map, and updating the overlapping area in the map of the target makeup into the overlapping area of the coloring map to obtain the drawing result of the target makeup.
After the overlapping area of the overlay of the target makeup and the coloring overlay is determined, the coloring parameters in the overlapping area of the coloring overlay can be interpolated into the overlapping area of the overlay of the target makeup to update the overlay of the target makeup to obtain the drawing result of the target makeup.
Step S312, performing an enlargement process on the overlapping area in the drawing result, and performing a gaussian blur process on the color of the enlarged overlapping area to obtain a final drawing result.
In order to achieve the softening effect and better viewing effect of the drawing result of the target makeup, after step S310, the preset script of the CPU sends an instruction, and the instruction performs an amplification process on the overlapping area in the drawing result, that is, the drawing area of the map of the current target makeup, and then performs a gaussian blur process on the color of the amplified area, and a final drawing result is obtained after the process is completed. The gaussian blur processing is also implemented by a shader.

The mode can realize the GPU-based role makeup drawing on the mobile equipment, the freedom degree of a player for the self definition of roles is improved in the affordable performance overhead, meanwhile, the difficulty of the player in drawing the self-defined makeup is reduced through some auxiliary technologies under the condition that the mobile terminal is difficult to control, the unique makeup experience is brought to the player, and the game experience of the player is improved.
