Sketch Gypsum Geometry was written by Wei Yuqiang, and it is an introductory book for sketching. Sketch is the foundation of all plastic arts, and geometric sketch with plaster is the first step of sketch. Through the study of geometry, it is convenient for beginners to understand the physical structure of objects, understand the principle of light and shade change of object blocks, and master how to express the sense of space in the plane.

Chen Yongzhong, the author of Sketch Geometry, described the painting skills of Sketch Geometry. From the form of painting, sketch is a painting drawn in monochrome. It refers to a painting form that uses monochromatic lines or surfaces to shape the physical structure of an object and express its volume, space, texture, sense of quantity and other elements.

Structure sketch Model of Single Geometry is a book published by Hubei Fine Arts Publishing House on 20 1 1. The author is Liu Jun. The purpose of basic sketch training is not only how to express objects technically, but more importantly, to learn to correctly observe and understand the modeling characteristics of objects and master the essential structure and general modeling rules of objects. This is actually a positive and rational thinking process. Only under the premise of accurate morphological structure, it is possible and necessary to further study the scene, texture and light and shade.
