It should be noted that the above application scenarios are only shown for the convenience of understanding the spirit and principles of the present disclosure, and the embodiments of the present disclosure are not limited in this respect. Rather, the embodiments of the present disclosure can be applied to any scenario where applicable.

Referring to FIG. 2 , which is a schematic flowchart of a method for dissolving a liquid material according to an embodiment of the present disclosure.

The liquid material dissolving method includes the following steps:

Step S210 , acquiring a target liquid material and a noise map of the same size as the target liquid material, and associating the transparency of the target liquid material with the grayscale value of the noise map.

Among them, the liquid material is a kind of material, and the noise map is a kind of texture.

In the field of computer animation (CG, Computer Graphics), the material (Material) contains the map (Map), and the map contains the texture (Texture). Texture is the most basic unit of data input, and maps are used to map textures to the surface of 3D objects through UV coordinates. The map also contains other information besides the texture, such as UV coordinates, texture input and output controls, etc. Among them, U and V are used to represent the horizontal and vertical axes of 2D space, since X, Y and Z are already used in 3D space. A material is a dataset whose main function is to provide data and lighting algorithms to the renderer. The map is a part of the data. Depending on the purpose, the map will be divided into different types, such as Diffuse Map, Specular Map, Normal Map and Gloss Map. Wait.

Referring to FIG. 3 , it is a schematic diagram of a liquid material provided according to an embodiment of the present disclosure. Among them, the light-colored part is the liquid part, and the dark-colored part is the background. When the liquid dissolves, the light-colored part gradually disappears. The essence is to display some pixels and some pixels to disappear.

Referring to FIG. 4 , it is a schematic diagram of a noise map provided according to an embodiment of the present disclosure. The noise map is a black and white map in which there are only two colors of black and white. The degree of black and white of each pixel in the noise map can be represented by a value between 0-1, which can be called this value. is the gray value.

In some exemplary embodiments, the noise map may be randomly generated. Among them, the gray 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.

In some exemplary embodiments, the noise map may be set to generate.

For a pixel in the target liquid material, the value of the transparency of the pixel is set to the value of the gray value of the pixel corresponding to the position coordinate of the pixel in the noise map.

The liquid material has 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 gray 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 gray value of the pixel corresponding to the position coordinate of the pixel in the noise map, and the liquid is established. The relationship between the material and the noise map, so that the transparency of the liquid material can be controlled by controlling the gray value of the noise map, and the dissolution effect of the liquid material can be achieved. Specifically, if the gray value is gradually reduced, the transparency gradually becomes 0, and each pixel is gradually transparent and invisible. When the transparency is 0, each pixel is completely transparent and invisible, showing the effect of completely dissolving the liquid. .

Different noise maps can be used to achieve different dissolution effects. The liquid can be dissolved randomly according to the randomly generated noise map, or it can be dissolved according to the set rules according to the noise map generated by the settings.

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

Among them, offset reorganization refers to offsetting the image by a defined number of pixels, moving any pixels outside the boundaries of the original image to the other side of the image to fill in the gaps created by moving the image, so that no part of the image is lost .

Step S240: Input the offset grayscale information into the texture sampler to obtain the normal map of the dissolution effect output by the texture sampler.

In some exemplary embodiments, by controlling the thickness parameter, the thickness of the dissolution edge of the target liquid material can be controlled.

In specific implementation, the thickness parameter matches the thickness of the liquid material.
