A Study On The Motion Model Of Brush Stroke In Calligraphy And Painting

When viewing a work of calligraphy and painting,the viewer can feel the suggestive movement from the static brushstrokes,and the movement will be simulated unconsciously in the brain.This psychological phenomenon is widely documented in various artistic documents and is classified as one of the important perceptual modes of "Embodied Aesthetics".It also has its physiological basis in neuro-aesthetic research,but the research on this kind of aesthetic phenomenon still stays in the aspect of aesthetic preference and brain nerve activity.Past research and practice have not tried to obtain the "data" of the imaginary brushstroke movement from the brain,there is also no attempt to recreate the artwork in a new form based on it.The current technology cannot directly obtain the specific data of the imaginary brushstroke movement in the human brain,but fortunately,this paper can get inspiration from the common practice of "copying" in traditional calligraphy and painting: "copying"can be regarded as an enhanced "brush stroke".Simulation",which requires the trainer to purposefully imagine the movement of the brushstroke and imitate it completely,and the result can be regarded as the brushstroke movement data in the mind actively output by the trainer.At the same time,referring to the description of motion in physics,this paper argues that the imaginary sense of brushstroke motion can be expressed in two ways:sense of speed and sense of trajectory,that is,the instantaneous description and cumulative effect of motion sense.The sense of speed is the subjective speed felt by the viewer from the stroke at each position of the reference block,and it is the local and instantaneous sense of the so-called imaginary stroke movement.Trajectory sense is the viewer’s subjective trajectory along the velocity implied by the brushstroke,and it is a cumulative description of the imagined brushstroke movement.Based on the above-defined brushstroke "sense of motion",this paper conducts research on the following three aspects:(1)Drawing on the behavior of "copying" and the above-mentioned dismantling of "sense of motion",two interactive "painting" applications were developed,allowing users to draw their perceived brushstroke movements on the reference artwork.At the same time,according to the two interactive programs,corresponding experiments were designed to measure the sense of speed and trajectory of brush strokes.(2)Model the velocity sense data collected by the experiment as a random velocity field;model the trajectory sense data as a stochastic process.In order to explore the researchability of the brushstroke motion data related to calligraphy and painting,the two kinds of experimental data were quantitatively studied,which showed that they could be analyzed mathematically.(3)Various forms of visualization are designed for the data.The main design basis of visualization comes from two quality indicators: fidelity and aesthetics.Fidelity prioritizes the presentation of statistical features,while aesthetics prioritizes artistic reproduction based on data.In addition,this study also considers both static and dynamic visualizations based on representation.The purpose of this paper is to obtain the specific content of the imaginary brushstroke movement as data research,which can open the door to the quantification of imaginary brushstroke movement,and show the possibility of using scientific methods to quantitatively analyze aesthetic feelings.In addition,through the visualization of the obtained data,this paper tries to present the virtual aesthetic feeling on the screen figuratively,intuitively and dynamically.Especially the dynamic visualization makes the originally static works modeled as a dynamic process according to the brushstroke movement,giving the works more meaning.These visualization results can be regarded as a quantitative method to study the artistic style of visual art works,and can also be regarded as a way to create new media art based on classic visual art works,which is of great significance to the promotion and inheritance of traditional Chinese and Western painting and calligraphy works.
