How to let novices master the perspective and volume expression of gypsum geometry
Sketch is a direct comparison with physical objects, which has clear standardization and accuracy.
The normal teaching of sketch often begins with geometric plaster form, because geometric form is the basic element of all complex forms.
The content of sketch includes the requirements of visual modeling factors such as space, proportion and perspective.
Sketch training of gypsum sculpture is a compulsory course in many art colleges, because it has the characteristics of monosyllabic and static, which is convenient for students to learn modeling better from observation.
The first step of sketch training is often to sketch a human hand from a still life. Through this kind of training, we can understand all forms of diversity in the surrounding reality.
Sketch shows that objects have space, shape, volume, structure and light and shadow.
Gypsum sketch enables students to study graphics with accuracy that they cannot achieve when drawing graphics and models.
Mastering the sketch of gypsum geometry is the premise of expressing other complex shapes.
10 plaster image not only helps students to deal with the living model better and more easily in the study of proportion and relationship, but also reflects the general shape in the plaster image.
1 1 Plaster is an artistic image refined by artists, which allows students to consciously breathe the artistic atmosphere while completing their homework, which is a subtle improvement of students' aesthetic consciousness.
12 completed the practice of plaster statue and naturally entered the portrait practice. Portraits are richer than plaster casts because people are alive.
13 Visually, when we observe a shape from a certain angle, the outer edge of the shape is reduced to a thinner edge line due to perspective, which is the contour line.
At the junction of 14, you can see the obvious hidden line, which is the structural line.
15 in the process of painting, connect the points related to the spatial position of various parts of the body, guide the structural relationship of various parts with imaginary lines, and strengthen the expression of spatial sense. This is called an auxiliary line.
16 Based on the subjective feeling and expression intention of the image, the lines emphasized or expressed by the image are used in painting, which is a subjective line.
