Embodiment
Below in conjunction with accompanying drawing, the embodiment of the method for texture image splicing of the present invention is described in detail.
As shown in Figure 1, a kind of method of texture image splicing, comprises step:
S110, to the former pixel of cutting figure of surrounding expansion, obtain Xin Qietu;
When the reason that texture piece produces is the edge of sampling local texture image, part texture cell disappearance, cuts figure so solution piece problem need to be repartitioned texture, and to the former pixel of cutting figure of external expansion, the figure adjacent part of cutting after expansion has overlapping;
The minimum value of the pixel of expansion can be definite according to video card decimation factor, and for example the decimation factor of video card is 2*2, and the minimum value of the pixel of expansion is 1; The pixel all directions of expansion can be identical, also can be different, for example, as shown in Figure 2, the former figure of cutting all can be expanded to n pixel to surrounding, also can be as shown in Figure 3, by expanding n pixel in the former figure of cutting horizontal direction, in vertical direction, expand m pixel etc.; In order to improve the operating efficiency of video card, the pixel of expansion is generally got minimum value;
Suppose that the former figure of cutting size is size*size, the former figure of cutting before Xin Qietu compares edge increases n pixel more, and the size of Xin Qietu is (size+2*n) * (size+2*n) so.The preserving type of picture is upper left corner coordinate, width and height, as shown in Figure 2, if the upper left corner coordinate of horizontal first Xin Qietu is [0,0], the upper left corner coordinate of second so horizontal Xin Qietu is [size, 0], the upper left corner coordinate of the 3rd horizontal Xin Qietu is [2*size, 0], the like the horizontal j upper left corner coordinate of opening Xin Qietu be [j*size, 0]; Second Xin Qietu upper left corner coordinate is [0, size] longitudinally ... the like the i upper left corner coordinate of opening Xin Qietu be [0, i*size];
S120, according to the pixel of the pixel of the former figure of cutting and Xin Qietu, determine scale down, the default sample range of texture coordinate is dwindled according to described scale down;
Texture coordinate has defined which part of texture image will be mapped on entity, and the texture coordinate of sampling being cut to figure is arranged in [0,1] scope, then the scope of texture coordinate is dwindled according to definite scale down;
S130, according to the pixel of expansion and the pixel of Xin Qietu, determine and treat offset displacement, the texture coordinate after dwindling is treated to offset displacement moves according to described;
For the effect that the texture pixel of the Xin Qietu of sampling is shown is the same with the former figure of cutting, solve the piece problem between different texture simultaneously, the texture coordinate after reducing the scope need to be moved according to the offset displacement for the treatment of of determining;
S140, according to the scope of the texture coordinate after movement, described Xin Qietu is sampled, texture pixel display effect out of sampling is with former to cut figure the same, and while having avoided sampling texture image border, the disappearance of part texture cell, has realized the seamless spliced of many textures.
Scale down in step S120 can comprise the scale down of horizontal direction and the scale down of vertical direction;
