[0059] To make the objectives, technical solutions, and advantages of the present disclosure more clearly understood, the principles and spirit of the present application will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are provided solely to enable those skilled in the art to better understand and implement the present disclosure, and are not intended to limit the scope of the present application in any way. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0060] According to an embodiment of the present disclosure, a method, device, electronic device, and storage medium for dissolving a liquid material are proposed.

[0061] It should be understood herein that any number of elements in the drawings is for illustration only and not for limitation, and any naming is only for distinction and does not have any limiting meaning.

[0062] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should have the usual meanings understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the embodiments of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the described object changes, the relative position relationship may also change accordingly.

[0063] The principles and spirit of the present application are explained in detail below with reference to several representative implementations of the present application.

[0064] In related technologies, when achieving a dissolving effect with a liquid material having a certain thickness, the performance is greatly affected.

[0065] The inventors of this disclosure discovered that the significant performance impact of the aforementioned related techniques is due to the fact that, in these techniques, intrinsic colors and normals are rendered separately as sequential frames (sequential frames: a moving video is represented by image files frame by frame), and then the sequential frames are played through a material to achieve a thick dissolving effect of a liquid material. To make the dissolving effect appear smooth and realistic, this implementation requires a large number of intermediate frames. However, the more intermediate frames, the larger the image, and the larger the image, the greater the performance impact. Reducing the number of intermediate frames affects the smoothness of the dissolving effect.

[0066] In order to solve the above problems, this application provides a liquid material dissolution solution, which specifically includes:

[0067] Obtain a target liquid material and a noise map of the same size as the target liquid material, and associate the transparency of the target liquid material with the grayscale value of the noise map; perform a smooth transition on the noise map through a smooth step function, and extract the grayscale value of the noise map after the smooth transition as the initial grayscale value; perform an offset reorganization on the noise map after the smooth transition, extract the grayscale value of the noise map after the offset reorganization as the offset grayscale value, and subtract the initial grayscale value from the offset grayscale value to obtain offset grayscale information; input the offset grayscale information into a texture sampler to obtain a dissolution effect normal map output by the texture sampler; merge the dissolution effect normal map with the original normal map of the target liquid material; and achieve dissolution of the target liquid material by controlling the smooth step function. The present disclosure does not require an intermediate frame, and thus can achieve dissolution of liquid material with thickness with minimal impact on performance.

[0068] After introducing the basic principles of the present application, various non-limiting implementation methods of the present application are described in detail below.

[0069] refer to Figure 1, which is a schematic diagram of an application scenario of the liquid material dissolution method provided in an embodiment of the present disclosure. The application scenario includes a terminal device 101, a server 102 and a data storage system 103. Among them, the terminal device 101, the server 102 and the data storage system 103 can be connected through a wired or wireless communication network. The terminal device 101 includes but is not limited to a desktop computer, a mobile phone, a mobile computer, a tablet computer, a media player, a smart wearable device, a personal digital assistant (PDA) or other electronic devices that can realize the above functions. The server 102 and the data storage system 103 can both be independent physical servers, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms.

[0070] The server 102 is used to provide liquid material dissolution service to the user of the terminal device 101. The terminal device 101 is installed with a client that communicates with the server 102. The user can input the liquid material and thickness parameters to be dissolved through the client. After clicking the OK button, the client sends the liquid material and thickness parameters to the server 102. The server 102 uses the liquid material to be dissolved as the target liquid material, obtains a noise map with the same size as the target liquid material, and associates the transparency of the target liquid material with the grayscale value of the noise map; the noise map is smoothed by a step function. The image is smoothed, and the grayscale value of the noise map after the smooth transition is extracted as the initial grayscale value; the noise map after the smooth transition is offset and reorganized, and the grayscale value of the noise map after the offset and reorganization is extracted as the offset grayscale value, and the initial grayscale value is subtracted from the offset grayscale value to obtain the offset grayscale information; the offset grayscale information is input into the texture sampler (the thickness parameter acts on this) to obtain the dissolution effect normal map output by the texture sampler; the dissolution effect normal map is merged with the original normal map of the target liquid material; and the dissolution of the target liquid material is achieved by controlling the smooth step function.

[0071] The data storage system 103 is used to store data.

[0072] The following combination Figure 1 The liquid material dissolution scheme according to the exemplary embodiment of the present disclosure is described with reference to the application scenario. It should be noted that the above application scenario is only shown to facilitate understanding of the spirit and principles of the present disclosure, and the embodiments of the present disclosure are not limited in this respect. On the contrary, the embodiments of the present disclosure can be applied to any applicable scenario.

[0073] refer to Figure 2, which is a flow chart of the liquid material dissolution method provided in an embodiment of the present disclosure.

[0074] The method for dissolving a liquid material comprises the following steps:

[0075] Step S210 : Obtain a target liquid material and a noise map of the same size as the target liquid material, and associate the transparency of the target liquid material with the grayscale value of the noise map.

[0076] Among them, liquid material is a material and noise map is a map.

[0077] In computer graphics (CG), materials contain maps, which in turn contain textures. Textures are the most basic unit of data input, used to map textures onto 3D surfaces using UV coordinates. Maps also contain other information beyond textures, such as UV coordinates and texture input and output controls. U and V represent the horizontal and vertical axes of 2D space, as X, Y, and Z are already used in 3D space. A material is a data set whose primary function is to provide data and lighting algorithms to the renderer. Textures are part of this data set, and depending on their purpose, they are categorized into different types, such as diffuse, specular, normal, and gloss maps.

[0078] refer to Figure 3 , which is a schematic diagram of a liquid material provided according to an embodiment of the present disclosure. The light-colored portion is the liquid portion, and the dark-colored portion is the background. As the liquid dissolves, the light-colored portion gradually disappears. The essence of this is to make some pixels appear while others disappear.

[0079] refer to Figure 4 , which is a schematic diagram of a noise map provided according to an embodiment of the present disclosure. A noise map is a black-and-white map, consisting of only two colors: black and white. The degree of blackness or whiteness of each pixel in the noise map can be represented by a value between 0 and 1, which can be called a grayscale value.

[0080] In some exemplary embodiments, the noise map may be randomly generated, wherein the grayscale value of each pixel is a random number between 0 and 1, and each random number is discrete and has no relationship with each other.

[0081] In some exemplary embodiments, a noise map can be generated by setting a continuous process, i.e., interpolation, to fill gaps between discrete data using interpolation functions to create a natural continuity. Interpolation functions can include trigonometric functions, normal distributions, spline curves, and the like.

[0082] refer to Figure 5 , which is a schematic diagram of the liquid material being dissolved without thickness according to an embodiment of the present disclosure.

[0083] In some exemplary embodiments, associating the transparency of the target liquid material with the grayscale value of the noise map includes:

[0084] For a pixel point in the target liquid material, the transparency value of the pixel point is set to the grayscale value of the pixel point corresponding to the position coordinate of the pixel point in the noise map.

[0085] Liquid materials have a transparency property. When the transparency is 0, it is completely transparent and invisible (dissolved), and when the transparency is 1, it is completely opaque (not dissolved). The grayscale value of the noise map is associated with the transparency of the liquid material, so that the transparency value of each pixel in the liquid material is the grayscale value of the pixel corresponding to the position coordinate of the pixel in the noise map, and the connection between the liquid material and the noise map is established. The transparency of the liquid material is controlled by controlling the grayscale value of the noise map, and the dissolution effect of the liquid material is achieved. Specifically, the grayscale value is gradually reduced, and the transparency gradually becomes 0, and each pixel gradually becomes transparent and invisible, until the transparency is 0, each pixel is completely transparent and invisible, showing the effect of complete liquid dissolution.

[0086] Different dissolving effects can be achieved by using different noise maps. The liquid can be dissolved randomly according to the randomly generated noise map, or it can be dissolved according to the set rules based on the noise map generated by the setting.

[0087] By controlling the noise map to achieve the liquid dissolving effect, the frame rate does not need to be considered, and the dissolving of liquid materials can be achieved with minimal impact on performance. However, it lacks the representation of liquid thickness, and the effect is flat and not three-dimensional, and the effect of liquid thickness cannot be reflected in the performance.

[0088] Step S220 : performing smooth transition processing on the noise map using a smooth step function, and extracting the grayscale value of the noise map after the smooth transition as the initial grayscale value.

[0089] In some exemplary embodiments, the smooth step function includes a maximum parameter and a minimum parameter;

[0090] The noise map is smoothly transitioned by a smooth step function, including:

[0091] For a pixel point in the noise map, in response to determining that the grayscale value of the pixel point is greater than the maximum value parameter, the grayscale value of the pixel point is set to the maximum grayscale value; in response to determining that the grayscale value of the pixel point is less than the minimum value parameter, the grayscale value of the pixel point is set to the minimum grayscale value.

[0092] As an example, the maximum grayscale value is 1 and the minimum grayscale value is 0.

[0093] In specific implementation, by controlling the minimum value parameter of the smooth step function to gradually increase and the grayscale value to gradually decrease, the transparency gradually becomes 0, and each pixel gradually becomes transparent and invisible, until the transparency reaches 0, each pixel is completely transparent and invisible, presenting the effect of complete dissolution of the liquid.

[0094] In some exemplary embodiments, the grayscale values of the noise map are extracted by a texture sampler.

[0095] The texture sampler can split the texture and obtain the grayscale value of the four RGBA channels, as well as the UV information of the texture. Among them, RGBA is a color space representing Red (red), Green (green), Blue (blue) and Alpha (opacity).

[0096] Step S230 , performing offset reorganization on the noise map after smooth transition, extracting the grayscale value of the noise map after offset reorganization as the offset grayscale value, and subtracting the initial grayscale value from the offset grayscale value to obtain offset grayscale information.

[0097] refer to Figure 6 , which is a schematic diagram of offset grayscale information provided according to an embodiment of the present disclosure.

[0098] In some exemplary embodiments, the offset grayscale information includes first offset grayscale information and second offset grayscale information;

[0099] The noise map after smooth transition is offset and reorganized, and the grayscale value of the noise map after offset and reorganization is extracted as the offset grayscale value. The initial grayscale value is subtracted from the offset grayscale value to obtain the offset grayscale information, which specifically includes:

[0100] The noise map after the smooth transition is offset by a first preset distance along the horizontal axis, and the portion of the noise map that exceeds the original boundary after the offset is moved to the other side of the noise map to obtain a first offset noise map, and the grayscale value of the first offset noise map is extracted as a first offset grayscale value, and the initial grayscale value is subtracted from the first offset grayscale value to obtain first offset grayscale information;

[0101] The noise map after the smooth transition is offset by a second preset distance along the vertical axis direction, and the portion that exceeds the original boundary of the noise map after the offset is moved to the other side of the noise map to obtain a second offset noise map. The grayscale value of the second offset noise map is extracted as the second offset grayscale value, and the initial grayscale value is subtracted from the second offset grayscale value to obtain the second offset grayscale information.

[0102] In some exemplary embodiments, the first preset distance is equal to the second preset distance.

[0103] Among them, offset reconstruction refers to shifting the image by a defined number of pixels, moving any pixels outside the original image boundary to the other side of the image to fill the gaps created by the shifted image, so that no part of the image is lost.

[0104] Step S240: Input the offset grayscale information into the texture sampler to obtain a dissolve effect normal map output by the texture sampler.

[0105] refer to Figure 7 , which is a schematic diagram of an offset grayscale information input texture sampler provided according to an embodiment of the present disclosure.

[0106] In some exemplary embodiments, the texture sampler includes an r channel, a g channel, and a b channel;

[0107] Input the offset grayscale information into the texture sampler to obtain the dissolve effect normal map output by the texture sampler, specifically including:

[0108] Input the first offset grayscale information into the r channel of the texture sampler;

[0109] Input the second offset grayscale information into the g channel of the texture sampler;

[0110] The first offset grayscale information and the second offset grayscale information are multiplied by the thickness parameter respectively and then input into the b channel of the texture sampler, and then cross-producted.

[0111] In some exemplary embodiments, by controlling the thickness parameter, the thickness of the dissolving edge of the target liquid material can be controlled.

[0112] In practice, the thickness parameter matches the thickness of the liquid material.

[0113] Step S250: Merge the dissolve effect normal map with the original normal map of the target liquid material.

[0114] In some exemplary embodiments, merging the dissolve effect normal map with the original normal map of the target liquid material includes:

[0115] Add one to the value of the r channel, the value of the g channel, and the value of the b channel of the original normal map as the first three-dimensional vector;

[0116] Multiply the value of the r channel of the dissolve effect normal map by negative one, the value of the g channel by negative one, and the value of the b channel as the second three-dimensional vector;

[0117] Perform a dot product of the first three-dimensional vector and the second three-dimensional vector to obtain a dot product value;

[0118] Multiply the dot product value by the first three-dimensional vector to obtain the first RGB value;

[0119] Add one to the value of the b channel of the original normal map and multiply it by the second three-dimensional vector to obtain the second RGB value;

[0120] Subtract the second RGB value from the first RGB value to achieve the fusion of the dissolve effect normal map and the original normal map.

[0121] Step S260 : dissolving the target liquid material by controlling the smooth step function.

[0122] In some exemplary embodiments, dissolution of the target liquid material is achieved by controlling a smooth step function, specifically including:

[0123] The dissolution of the target liquid material is achieved by gradually increasing the minimum value parameter of the smooth step function.

[0124] refer to Figure 8 , which is a schematic diagram of the dissolution of a liquid material band with thickness provided according to an embodiment of the present disclosure.

[0125] During specific implementation, the thickness of the dissolving edge of the target liquid material is controlled by controlling the thickness parameter; by gradually increasing the minimum value parameter of the smooth step function and gradually reducing the grayscale value, the transparency gradually becomes 0, and each pixel gradually becomes transparent and invisible, until the transparency reaches 0, each pixel is completely transparent and invisible, presenting the effect of complete dissolution of the liquid.

[0126] As can be seen from the foregoing, the liquid material dissolution method, device, electronic device, and storage medium provided by the embodiments of the present disclosure achieve a liquid dissolution effect by controlling the noise map, without considering the impact of frame rate, and can achieve liquid material dissolution with minimal impact on performance. Furthermore, by fusing the constructed dissolution effect normal map with the original normal map, it is possible to achieve liquid material dissolution with thickness.

[0127] It should be noted that the method of the embodiments of the present disclosure can be performed by a single device, such as a computer or server. The method of the embodiments of the present disclosure can also be applied in a distributed scenario, where multiple devices cooperate to perform the method. In such a distributed scenario, one of the multiple devices may only perform one or more steps of the method of the embodiments of the present disclosure, and the multiple devices will interact with each other to complete the method.
