Description

Technical Field

[0001] The invention relates to the technical field of game development, and in particular to a real-time game character and clothing dyeing method. Background Art

[0002] As electronic games mature, including online games and stand-alone games running on mobile phones, personal computers, game consoles and other devices, customizable game characters have become an important means to attract players. Among them, the coloring function of various parts of the character's body, clothing, etc. is an important part of character customization.

[0003] The traditional real-time dyeing algorithm is a dyeing method based on the material system. When the GPU calculates the pixel color in the game screen, the hue, saturation and brightness of the original color are adjusted, that is, the HSL color (referring to the color represented by hue, saturation and brightness) and RGB color (referring to the color represented by the three primary colors of red, green and blue) are converted to each other to achieve the dyeing function. This method can meet the most basic dyeing function, but the color effect produced is not rich enough, the color range is limited, and there is a problem of high GPU calculation complexity in real-time calculation, which affects the player experience in terms of picture performance and game operation efficiency. Therefore, this application provides a real-time game character and clothing dyeing method to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a real-time game character and clothing dyeing method to solve the problems of insufficient color effects, limited color range and high GPU calculation complexity.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A real-time game character and clothing dyeing method, comprising the following steps:

[0007] S1.1, the client responds to commands for controlling game characters and clothing dyeing;

[0008] S1.2, the CPU modifies the shading control parameters passed to the GPU through the material system;

[0009] S2.1, in the GPU, by reading a mask map in the material of the character or clothing, it is determined whether the pixel currently being calculated needs to be dyed;

[0010] S2.2, calculating the saturation of the current pixel, recording the result as the primary color saturation, calculating the saturation of the dyed color, and recording the result as the dyed color saturation;

[0011] S2.3, performing decolorization calculation on the current pixel point, and interpolating the decolorization result with the original color according to the decolorization degree of the parameter original color;

[0012] S2.4, multiplying the result of the decolorization calculation by the dyeing color, and adjusting the color saturation to obtain a preliminary dyeing color;

[0013] S2.5, according to the saturation adjustment parameter, interpolation calculation is performed between the primary color saturation and the dyeing saturation to obtain the target saturation;

[0014] S2.6, modifying the saturation of the preliminary dyeing color to a final saturation by calculation to obtain a final color;

[0015] S3, passes the final color as the calculation result to be used in other subsequent pixel color calculations, or directly outputs it and displays it on the screen.

[0016] In a possible implementation, the control parameters in S1.2 include tinting color, decolorization degree of primary color, and saturation adjustment parameters.

[0017] In a possible implementation, the calculation method of the saturation in 2.2 is Saturate = 1-(minimum brightness among primary colors RGB / maximum brightness among primary colors RGB).

[0018] In a possible implementation, the calculation method of the decolorization in S2.3 is: decolorization color=dot{original color, fl oat3(0.3, 0.59, 0.11)}.

[0019] In a possible implementation, the calculation method for adjusting the saturation in S2.4 is: setting the corresponding channel value of the minimum brightness in the primary color RGB to 0, and setting the corresponding channel value of the maximum brightness in the primary color RGB to 1.

[0020] In a possible implementation, the calculation method of the saturation modification in 2.6 is: final color = pure white (1) * final saturation + preliminary dyeing color * (1-final saturation).

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] By optimizing the algorithm for converting HSL colors to RGB colors, using simple multiplication to simplify the complex hue transformation calculations and completing the brightness calculations at the same time, the details lost due to the simplification algorithm are merged into the saturation calculation, thus taking into account both performance consumption and effect details without incurring additional production costs.
