Embodiment Construction

[0046] In order to further illustrate the features of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. The accompanying drawings are for reference and description only, and are not intended to limit the protection scope of the present invention.

[0047] Such as figure 1 As shown, the present embodiment discloses a drawing method for simulating brush strokes. The beginning and end of the curve drawn by the brush in one stroke are strokes, and the middle line segment is strokes, including the following steps S1 to S3:

[0048] S1. Collect coordinate point samples in real time, and store the collected coordinate point samples into the coordinate set according to the order of sampling time;

[0049] S2. Set the distance threshold and the sampling time difference threshold between the coordinate point samples to filter the coordinate point samples in the coordinate set;

[0050] S3. According to the dis...

Abstract

The invention discloses a drawing method for simulating brush strokes, belonging to the technical field of computer graphics processing. The method comprises the following steps of collecting the coordinate point samples in real time, and storing the collected coordinate point samples into a coordinate set according to the sampling time sequence; setting a distance threshold and a sampling time difference threshold between the coordinate point samples to filter the coordinate point samples in the coordinate set; according to the distance value and sampling time difference between adjacent coordinate point samples in the coordinate set, and by combining with the Bezier curve drawing mode, realizing the stroke drawing of the curve. By screening the collected coordinate point samples, the method of the invention realizes the optimization of the drawing fluency, and ensures the stable drawing under the low delay.

Description

technical field [0001] The invention relates to the technical field of computer graphics processing, in particular to a drawing method for simulating brush strokes. Background technique [0002] With the development of computer graphics, image software and hardware technology, computer-assisted calligraphy and painting drawing has become a research hotspot. At present, there are two commonly used drawing methods: one is to use the drawing interface functions that come with the development language to draw. Its disadvantages are: low drawing efficiency, long drawing time and delays. At the same time, the built-in function interface does not process the curve, resulting in serious problems of jagged curves and shadows, and the effect of brush strokes is poor. The second is to draw in combination with the function interface provided by the development language. For C++, it mainly uses Bezier curves to achieve drawing. First, calculate the data required for drawing, combine B...
