Abstract

The invention discloses a GPU-based all-liquid-crystal-instrument virtual pointer style drawing method, and belongs to the field of all-liquid-crystal-instrument virtual pointer style drawing. The problems that according to a traditional full liquid crystal instrument virtual pointer drawing method, drawn pointers are single in style and occupy more physical storage space, and CPU resources are consumed are solved. According to the GPU-based all-liquid-crystal-instrument virtual pointer style drawing method, the corresponding pointer style function can be directly called from the flash moduleof the full liquid crystal instrument, and the new color value of each displayed pixel point is obtained by combining the color value of each currently displayed pixel point, so that the drawing of the virtual pointer style of the full liquid crystal instrument is realized. The GPU-based all-liquid-crystal-instrument virtual pointer style drawing method is mainly used for drawing the virtual pointer style of the full liquid crystal instrument.

Description

technical field [0001] The invention belongs to the field of drawing virtual pointer styles of full liquid crystal instruments. Background technique [0002] The full liquid crystal instrument has the characteristics of flexible and diverse forms of expression. There are roughly two ways to realize the pointers such as speed and rotation speed as follows. [0003] One is the picture method, that is, the prepared 2D pointer picture is used to represent the pointer. In actual use, it is only necessary to rotate the picture to the corresponding angle around the central axis of the dial. The disadvantage of this method is that the content of the picture itself remains unchanged, that is, what it looks like at the time of design, and what it looks like in the watch. It is basically a simulation of the pointer of a traditional mechanical watch, and cannot give full play to the advantages of a full LCD instrument. To change the pointer style, the only way is to replace the pointer...
