Sketch painting with a sense of volume

First of all, you need to master the structure of the palm.

The skeletal structure of the hand is composed of 8 wrist bones, 5 long metacarpals and 14 phalanges arranged closely. The whole hand has 27 bones, 16 joints. The skeleton is mainly composed of styloid process of radius, ulna, triangle bone, skull, hamate, metacarpal bone and phalanx.

Hand muscles are mainly composed of abductor pollicis brevis, abductor digiti minimi and dorsal interosseous muscles. The basic shape of the palm is hexagonal. The shape of fingers is roughly several hexagonal truncated bodies.

Don't neglect the structure of the hand too much. The structure of the hand is interlocking, and the ratio of each section to each section is rhythmic. What you need to know is the structure of the hand, which is inseparable from the three parts that Xiao Zhi will talk about below.

Second, the proportional relationship between finger bones.

Below are two detailed finger analysis diagrams. The palm and fingers belong to a cuboid as a whole, but the length of each finger is not equal.

You can directly observe your fingers and put them together, and you will find that the position of each finger joint is in an arc trend, so it is easy for friends who are in contact for the first time to directly understand the parallelism.

So, how important is it to master the skeletal structure of the hand before this? You can imagine.

Third, understand the relationship between wrist, palm and finger.

The hand can be divided into three parts: wrist, palm and fingers. When drawing a hand, grasp the position of the turning bone between the palm and fingers, the lines should be slender, and you should be sure when performing.

Everyone should know that the wrist connects the hand with the forearm, and the wrist bone is connected with other bones of the hand to form a body, and the wrist moves with the hand.

For the analysis among the three, small partners can be divided in geometric form. (As follows: Analysis from three different angles, we distinguish this process in order to pay attention to what Xiao Zhi will talk about below).

Fourthly, the structural transformation of finger joints of different hands.

When sketching, each hand has a different posture. Different angles, light and shade and hand posture are the main factors that increase the difficulty of painting.

At the same time, there are many lines on the fingers, which are very obscene. Beginners generally don't like to draw hands, because if they don't draw well, they will draw chicken feet.

Pay attention to the relationship between fingers, wrists and sleeves, and the relationship between hands and other body parts or props when drawing hands. (Learn in the order listed in this issue of Xiao Zhi. Hold your ground first, and don't be too eager for success. )
