Step 201, corresponding first texture image of scene of game is obtained；
Step 202, response is requested for the drafting of the scene of game, by first texture image according to Gaussian Profile
Generate the second texture image；
After obtaining the first texture image, the corresponding channel color histogram of the first texture image can be generated, then adopt
It is distributed with standard gaussian, is mapped as standard gaussian distribution texture, obtains the second texture image.
Specifically, mapping can be executed respectively to Color Channel (RGB) each in the first texture image, it specifically can be to list
The pixel color of a Color Channel is ranked up, and generates channel color histogram.
After generating channel color histogram, sorting position of the pixel color in the color histogram of channel can be determined,
Then it is mapped according to sorting position, obtains the second texture image.

Number can recorde x point probability distribution below it is accumulative and, it is specific as follows:
Correspondingly, then needing the inverse function CDF using Cumulative Distribution Function from Gaussian Profile to channel color histogram-1
(x), specific as follows:
Wherein, erf is error function, and μ=0.5 (the Gaussian Profile image value of μ=0.5 is in [0,1] section) can be set,
σ=1/6 (σ=1/6 guarantees eight bit image floating point precisions).
Step 203, random offset is carried out according to second texture image and generates at least one sampling texture image；
After obtaining the second texture image, random offset can be carried out to the second texture image, and laggard in random offset

Middle any pixel point (each pixel has the first color value in image block), belongs to a certain image block, then carry out with
In sampling texture image after machine offset, corresponding second color value of the pixel can be determined in sampling texture image.
For example, in the second texture image image block three the first vertex (v1, v2, v3), sample texture image in second
Vertex (v4, v5, v6), for the pixel p of image block, original coordinates uv, then pixel p is pushed up relative to three second
The sample coordinate of point is (v4+ (uv-v1), v5+ (uv-v2), v6+ (uv-v3)), is adopted three times in three sample coordinates
