As shown in fig. 3, the self-luminous rendering process includes the following method steps:

step E31, drawing the self-luminous flow direction of the model in the model making software;

step E32, baking the drawn gray information graph and importing the gray information graph into an engine;

step E33, sampling the gray information graph, and taking a sampling result as a one-dimensional noise graph;

step E34, controlling the self-luminous movement by controlling the parameters of the one-dimensional noise map;

and E35, multiplying the processed noise parameters by the self-luminous maps, and inputting the calculation result into a rendering pipeline for rendering.

Specifically, in step E31, the self-luminous flow direction of the leg portion of the virtual character a is drawn using the Blender software. Fig. 4 is a schematic diagram of an alternative self-luminous flow direction drawing process according to an embodiment of the present invention, as shown in fig. 4, a self-luminous flow direction drawing can be performed in the blend software from a point where the gray-scale value is 0 (H0 point is a starting point) to a point where the gray-scale value is 1 (H1 point is an end point), and the drawing result is taken as self-luminous flow information.

Alternatively, during the drawing of the self-luminous flow direction, the gradation brush may be linear, that is, as shown in fig. 4, the gradation value is linearly changed between 0 and 1 on the self-luminous flow path drawn between H0 and H1.

It should be noted that, in order to maintain the continuity of self-luminescence of the leg portion of the virtual character a during the drawing process of the self-luminescence flow direction, the parameters (such as thickness, gradient, etc.), the range and the algorithm of the gradation brush in the Blender software can be controlled so that the gradation brush is drawn continuously within the leg portion drawing region of the virtual character a (to the continuous drawing region on the leg portion surface of the virtual character a, the corresponding gradation drawing range should be continuous). The slope of the graduating brush may refer to a drawing rate of the graduating brush between 0 and 1. The algorithm of the gradation brush may be a linear algorithm, a gamma algorithm, or the like. The range of the gradation brush means a range of gradation values associated with the brush drawing order.

It should be noted that, in the process of drawing the leg portion of the virtual character a in the self-luminous flow direction, the grayscale map covers the region to be rendered corresponding to the leg portion of the virtual character a, and therefore, the drawing in the self-luminous flow direction does not affect other regions of the surface of the virtual character a.

Specifically, in step E32, the self-luminous flow information drawn in step E31 is baked into a map, and a grayscale map P2 (corresponding to the second map described above) is obtained. The grayscale map P2 is imported to the Unity game engine.

It should be noted that the gray-scale map obtained by baking can be stored in the storage space separately, so that the gray-scale map (or self-luminous flow information) can be replaced and changed flexibly; and the mapping information can also be stored in a transparent channel of the self-luminous mapping of the leg part of the virtual character A, so that the workload of one mapping sampling in the subsequent rendering process is saved.

Specifically, in step E33, the model UV map P1 of the leg of the virtual character a is sampled to obtain an initial self-luminescence parameter, which is denoted as emision (corresponding to the first parameter); sampling the grayscale map P2 using a model UV map P1 (corresponding to the first map) of the leg of the avatar a to obtain a self-luminous flow parameter, which is denoted as emisionflow (corresponding to the third parameter); then, a preset one-dimensional noise map P3 (corresponding to the third map) is sampled based on the self-luminous flow parameter emisionflow, and a noise parameter is obtained and is written as noise (corresponding to the second parameter).

It should be noted that the preset one-dimensional noise map P4 may be a noise map that is pre-processed, wherein the pre-processing includes: fade-in processing, fade-out processing, and the like.

Fig. 5 is a schematic diagram of an alternative noise information graph according to an embodiment of the present invention, as shown in fig. 5, the noise information graph P5 carries the above noise parameter noise, the left edge in fig. 5 corresponds to a point (self-luminous flow starting point) with a gray-scale value of 0, and the right edge in fig. 5 corresponds to a point (self-luminous flow ending point) with a gray-scale value of 1.

Still as shown in fig. 5, the self-luminous impulse effect of the leg of the avatar a can be achieved by moving the noise information map P5. By modifying or replacing the noise information map P5, the self-luminous effect (such as the gradient of fade-in and fade-out, the noise distribution pattern, the pulse coverage, etc.) of the leg of the virtual character a can be adjusted.

Specifically, in step E34, the displacement control is performed on the noise information map P5 by controlling the displacement control parameters (including the Time control parameter Time and the speed control parameter speed) of the noise information map P5, so as to achieve the self-luminous flow effect.

Alternatively, the Time control parameter Time may control the spontaneous light of the leg portion of the virtual character a to automatically flow according to a designated Time rule, and the speed control parameter speed may control the speed of the spontaneous light of the leg portion of the virtual character a to automatically flow.

The method for adjusting the self-luminous flow parameter emisionflow corresponding to the noise information map P5 by using the Time control parameter Time and the speed control parameter speed may be as shown in the following formula (1):

emisson flow = emisson flow + Time × Speed formula (1)

In formula (1), emisionflow on the right side of the equation represents the self-luminous flow parameter before adjustment, and emisionflow on the left side of the equation represents the self-luminous flow parameter after adjustment.

Specifically, in step E35, the noise parameter noise is multiplied by the initial self-luminous parameter emision and input into the rendering pipeline for rendering, so that the self-luminous flow effect of the leg of the virtual character a can be obtained.

Fig. 6 is a schematic diagram of an alternative self-luminous rendering result according to an embodiment of the present invention, and as shown in fig. 6, a self-luminous flow rendering is performed by the method provided in the embodiment of the present invention, so that a self-luminous effect of the virtual model shown in fig. 6 can be obtained.

By the self-luminous rendering method, the self-luminous flowing effect of the virtual model can be realized, the dynamic sense of a virtual scene picture corresponding to the virtual model is realized, and the user experience is further improved.

In the self-luminous rendering method provided by the invention, a Bloom technology can also be used. By the Bloom technology, imaging of a real-world camera can be reproduced, computer image effects which can be used for video games, demonstrations and high-dynamic-range rendering can be achieved, image effects (such as stripes, feathers and the like) generated by the Bloom can extend into the computer image from the edge of a bright area, strong optical illusion is generated, and the scene effect is difficult to capture by the camera or a player with naked eyes.

It is easy to notice that the method provided by the invention has the following beneficial effects: the self-luminous flow effect of the virtual model can be realized without additionally arranging the map, so that the dependence of self-luminous flow rendering on the number of the surfaces of the model is avoided, and the control precision and the rendering stability of the self-luminous flow are improved.

It is easy to note that the method provided by the invention has the technical key points that: firstly, directly drawing self-luminous flow information of a model in model making software, wherein the self-luminous flow information is determined by a gray level map; then drawing the self-luminous flow direction determined by the self-luminous flow information on the model through a gradient brush to obtain a drawing result; leading the drawing result into a preset game engine, and taking the drawing result as a UV (ultraviolet) mapping in a coloring device of the game engine to carry out noise map sampling to obtain a sampling result; and performing self-luminous rendering according to the sampling result.
