1. First of all, on the basis of the original picture, cut off the information that will interfere with our judgment, such as hair caps, and find out the orientation, angle and perspective of the head.
2. After determining the general shape of the head, continue to analyze the thickness of the hair. In the picture, the clear intersection of hair and face is taken as the coordinate, and the horizontal and vertical of X axis and Y axis are made. At this time, we can see that the width of the horizontal plane is about equal to the thickness of the hair.
3. The length of the longitudinal hat from the top to the center is approximately equal to the length from the center to the collar.
4. The node from the transverse neck and mandible to the Y axis is approximately equal to the distance from the stamina to the Y axis.
5. The distance from the brim tip to the Y axis is approximately equal to the distance from the tip to the forehead hairline, and the ratio of the longitudinal distance from the brim tip to the eyebrows of the eyes can also be roughly seen.
With this method of observation and analysis, we can basically judge the general structural points of the copied object and the proportion of the horizontal and vertical axes. Some friends will wonder that hand-drawing on paper can't draw such a complicated reference line on the computer monitor, and this set can't be realized at all. In fact, this is actually to provide an analysis idea, and hand-drawing on paper can also use similar analysis techniques.
Operation method:
1. First, give the basic shape of the head. The orientation and perspective must be accurate, otherwise the reference axis behind will become larger and larger.
2. According to the above analysis method, the approximate reference coordinates are given. The more reference points, the simpler the subsequent connection will be.
3. Connect these coordinate points and draw a sketch.
4. Draw a clear line sketch.
