Why learn to draw and sketch from simple geometry?
When beginners sketch, teachers usually ask everyone to draw cubes, so that they can practice their ability to control lines. In addition, they can draw many geometric structures.

Geometric shapes exercise people's grasp of structure. The external forms of objects in the world we see are ever-changing, but in summary, they can be summarized into several basic geometric forms-cubes, cylinders, cones, spheres and so on. , is a morphological summary of ever-changing objects.

The objects we see every day have complex shapes. Beginners often don't know where to start, but we can generalize it with different geometric shapes, so it seems that complex objects can also be refined with this law and viewpoint, such as apples, which can be regarded as spheres and pears or cones. Including more complex portraits, we can use geometric shapes to summarize.

Therefore, learning the sketch of gypsum geometry can help us master the modeling law of realistic painting as soon as possible, so that we can express everything we want to express at will. Learning sketch should follow the principle of gradual progress. Gypsum geometry summarizes various forms of nature. From the study of gypsum geometry and still life, it is the beginning of sketch. Learning geometry is easy to understand the physical structure and perspective principle of objects in space, and it is easy to understand the light and dark tones and three-dimensional sense of objects.

These basic laws of sketch also run through all other complicated forms, almost including all kinds of relationships of sketch modeling. Through the understanding and description of geometric shapes, the ability to summarize various complex shapes is cultivated, which lays the foundation for further learning sketch.
