How to draw martial arts movement diagrams – the basic structure and proportions of the human body
How to draw martial arts movement diagrams (1)
There are many martial arts workers and enthusiasts, in order to record and organize martial arts routines, write martial arts manuscripts, often encounter the problem of how to draw martial arts action diagrams, the author based on his rough experience in actual work, talk about the basic methods of drawing martial arts action maps.
The basic structure and proportions of the human body analyze the composition of the human body from the perspective of human movement, and the human body can be summarized into three pieces, eight lines, and fourteen joints.
The three pieces are the head, chest and pelvis, the eight lines are the upper arms and legs of the lower limbs, and the fourteen joints are the neck and lumbar joints, and the left and right shoulders, elbows, wrists, hips, knees, and ankles (Figure 1).
The three major blocks of the human body themselves are basically unable to move, mainly relying on the neck and waist joints to twist, turn, and fold, constituting a vivid posture of the human torso (Figure 2).
The eight lines of the limbs follow the law of movement centered on the joint and the radius of the limb (Figure 3).
The proportions of the parts of the human body mentioned here are summarized and formulated according to the basic characteristics of young men and women in our country and combined with the principle of human beauty. It only provides a basic scale that allows us to have a basis when drawing action diagrams. The proportion of each part of the human body, measured in head length, is seven and a half heads, and the midpoint is at the pubic symphysis (Figure 4).
The neck joint to the lumbar joint occupies two head lengths, the pelvis occupies one head length, and the hip joint to the knee joint, and from the knee joint to the heel occupies two head lengths.
Because the hip joint is located in the middle of the pelvis, the lower limbs overlap the pelvis by half a head length, making a total of seven and a half heads tall. The arm length is 3 heads long, the upper arm and the small arm each account for the length of the head, and the palm is the head length.
In the drawing of martial arts movements, there is a song: “Li 75, bow hemp 6, single fork and double fork four heads.” That is to say, the height of the horse is seven and a half heads when standing upright, six heads tall when the horse steps lunge (Fig. 5), and only four heads tall when splitting (Fig. 6).
