Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] Such as Figure 1 to Figure 4 As shown, an efficient texture optimization method for large scene rendering includes the following steps:
[0026] (1) Merge the textures corresponding to the models to be merged to form a corresponding texture set; the texture set is a set formed by putting together multiple different textures;
[0027] (2) Each small texture in the texture set establishes a mapping relationship with the model data associated with the small texture;
[0028] (3) Sort the small textures in the texture set, including:
[0029] ① First gather all textures, determine the small texture corresponding to the maximum value of width or height, and record the small texture;
[0030] ②According to the small texture obtained in step ①, determine the maximum width or height of the small texture; if it is high, do not rotate; if it ...
