Embodiment Construction
[0021] Such as figure 1 As shown, it is a flow chart of the method for reducing the texture memory required for dynamic Chinese character generation in the present invention:
[0022] Step S1, generate the dot matrix of Chinese characters to be displayed; for the Chinese characters that need to be dynamically displayed for instant input, when generating Chinese characters into the texture, in fact, only interested in whether each pixel of the Chinese character is displayed, and the Chinese character dot matrix Each point represents a pixel, that is to say, one bit can store one pixel of a Chinese character, for example, a Chinese character using a 16×16 dot matrix requires a storage space of 16×16 / 8 equal to 32Byte, through By storing the dot matrix of the Chinese characters to be displayed, details such as the content, font, and distribution of the Chinese characters to be displayed can be determined; in addition, the Chinese character dot matrix used in the present invention...

A method for reducing texture memory required in dynamic Chinese character generation includes the following steps: S1. generating the lattice of a Chinese character to be displayed; S2. generating the graph of the Chinese character to be displayed according to the lattice of the Chinese character to be displayed; S3. creating a compressed format texture with the same dimension as the graph of the Chinese character to be displayed; S4. filling the graph of the Chinese character to be displayed correspondingly in the compressed format texture; and S5. saving the compressed format texture of the Chinese character to be displayed generated in S4. The method adopts compressed texture format to decrease the memory occupancy quantity in the dynamic Chinese character generation and converts the graph of the Chinese character into the compressed format texture in real-time speed, thus bringing down the demand of the dynamic Chinese character generation on the texture memory and further improving the display speed.
Description
technical field [0001] The invention relates to the technical field of Chinese character display, in particular to a method for reducing texture memory required for dynamic Chinese character generation. Background technique [0002] In existing computer platform applications, there are often situations where a large number of dynamic Chinese characters need to be displayed, for example, a large number of Chinese characters need to be dynamically displayed in a Chinese game running on a computer or a game machine. In the prior art, when displaying these Chinese characters, these Chinese characters need to be generated into the texture. Due to the huge number of Chinese characters, a large amount of texture memory is often required. For graphics accelerators (graphics cards) with limited available resources, the occupation of texture memory directly affects the display speed. Display speed is slow. Contents of the invention [0003] Therefore, the object of the present inv...
