Theoretical knowledge about sketch is still very important. Only under the guidance of theoretical knowledge can the ability of sketch be continuously improved. Sketch is a quick sketch technique, which belongs to a painting form as well as sketch. Portrait sketch is to draw a portrait sketch concisely in a short time with simple lines. On the steps of sketching character modeling
One: the law of human motion
To sketch the steps of characterization, we must first understand the laws of human motion. This is the most important thing. Under normal circumstances, the human body is active. The human body in motion is ever-changing, which is difficult for beginners to grasp. How to master the essentials of character movements? We can summarize it as "coordination of three limbs in one line, two hubs" and diagonal lines and dynamic modeling.
Two: diagonal application and dynamic modeling
In the process of sketching characters, some students do not pay attention to the analysis of the internal body structure or make a profound observation when facing the movements of models, and turn a blind eye to the dynamic characteristics of characters, thus drawing stiff, dull and dull movements. How can we make an action vivid and natural? The application of diagonal is a good way to correct dynamic modeling.
Methods: The human body was divided into 1 1 independent units, including head, chest, buttocks, left forearm, left upper arm, right forearm, right upper arm, left thigh, left calf, right thigh and right calf. Every part participates in human activities, and presents a certain amplitude and inclination to varying degrees. This tilt can be completely felt by visual inspection.
Three: the performance of lines
Lines not only have the function of expressing body lumps, but also have rich expressive power. Sketching the steps of characterization is of great significance for enhancing the picture effect and conveying the author's aesthetic intention. There are many changes in lines, such as length, thickness, virtual reality, intensity, Fiona Fang, frustration, mutation and so on. There are also organizational changes such as density, convergence and dispersion. The expressive force of lines is the basic skill to improve the dynamic sketch of characters.
