Problems solved by technology

[0004] At present, the main focus of research on electronic calligraphy is how to render brush handwriting closer to reality, but the current method has two main disadvantages: first, the algorithm is complex, the calculation is large, and the software processing speed cannot reflect the real writing speed in real time. The trajectory is delayed in display, resulting in data loss, the writing trajectory cannot be displayed, and the writing speed is limited; the second is that the handwriting simulation effect is not ideal
These problems directly affect the user experience of e-calligraphy

Embodiment Construction

[0081] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0082] The hardware environment based on the present embodiment is: an infrared touch screen that can identify the size of the contact area of ​​the brush, and an imitation brush similar to a real brush (a real brush can be used instead, and the texture of the brush hair must be similar to the real brush).

[0083] The method for generating the real-time trajectory of the soft pen in the present embodiment is a method for truly restoring the real-time trajectory of the soft pen on the electronic display, such as figure 1 shown, including the following steps:

[0084] Step S1, handwriting point collection

Abstract

The invention discloses a soft pen real-time trace generation method. The method comprises the steps that a trace point F(i+1) at the current position of a handwriting trace is collected; after the trace point F(i+1) is denoised, a trace point ^F(i+1) is obtained; an interpolation point is obtained between the trace point ^F(i+1) and a trace point ^Fi; the size and the ink amount of strokes of the trace points and the interpolation point are calculated; an iterative region is selected; based on the trace point ^F(i+1), the trace point ^Fi, the interpolation point and the size and the ink amount of the strokes of the points, in the selected iterative region, trace diffusion and rendering processing are conducted by means of a preset four-layer iterative model, and a rendered trace is generated. According to the method, the trace generation speed is improved, and the problem of delay of writing display is effectively solved.

Description

technical field [0001] The invention relates to the field of non-realistic rendering, in particular to a method for generating a real-time trajectory of a soft pen, a storage medium, and a processing device. Background technique [0002] The art of calligraphy is an art with a long history. Calligraphy refers to an art that uses the four treasures of the study, such as paper, ink, brush, and inkstone, as tools to express emotions. The particularity of tools is an important aspect of the particularity of calligraphy art. Using the Four Treasures of the Study as a tool to fully reflect the performance of the tool is an important part of calligraphy techniques. The pen endows calligraphy with rich and colorful techniques. Fully embodies the charm of calligraphy. [0003] With the increasing popularity of computer applications, the use of electronic brushes to display the charm of calligraphy on electronic screens has brought new changes to the art form of calligraphy. [00...
