Before painting structure sketch, the painter should first examine the topic and analyze the basic modeling structure of the still life to be depicted. The teacher of the design studio suggested that the painter could sketch the basic shape of each object separately on the draft paper when time allowed, and further analyze the basic structure of each object shape to help students understand the ins and outs of the modeling structure of each object.
Step 2: Determine the basic composition and sketch the formal composition.
Composition is generally the focus of our emphasis. In the composition stage, students can also sketch out several composition forms on the draft paper, and compare which composition form can better arrange the content in the topic to form a vivid and concise picture. We have repeatedly stressed that we should pay attention to the distinction between primary and secondary composition, arrange the main object in the visual center, and pay attention to the balance and echo of the picture. In addition, from the visual effect, the main composition space of the object is larger than the secondary space.
Step 3: Draw a general outline according to the proportional relationship between still life and life.
On the basis of silently drawing large geometric figures, the basic proportional relationship of each figure is further drawn. Of course, there is no fixed formula for the scale factor, which changes with people's perspective. In structure sketch's paintings, we should pay attention to depicting various proportional relations from the same perspective, and form the proportional relations of big, small, square and circle through the mutual comparison of objects. In addition, in structure sketch dictation test, candidates are most prone to make various mistakes in proportion, such as drawing a small hot pot, a big egg, a small plate and a big apple, which are all caused by the lack of scale concept and repeated comparison. Accurately grasping the proportional relationship in painting is one of the key problems to solve the modeling ability of candidates in dictation painting.
Step 4: Pay attention to the structural relationship to avoid the monotony of still life in sketch.
After we have obtained the correct proportional relationship, it is the key to shape the body to further silently draw various structures of objects in structure sketch's works. When you silently draw the structure of an object, you should avoid drawing the structural frame with a hook outline, and you can't just draw the visible structural relationship. The interpretation of the structure should proceed from the whole, draw the turning point and continuation of various structural planes silently from the perspective of perspective anatomy, and pay attention to the interpenetration of understanding forms to prevent monotony and emptiness. The way to draw the structural relationship silently is to start with the overall decent hand, find the small decent in the big decent, and then find the local decent in the small decent.
Step 5: Deeply shape the body and emphasize the spatial relationship.
Structure sketch's still life paintings got rid of the influence of light and shade, and removed the depiction of light and shade tones. It focuses on the combination and movement law of various parts in the physical structure of an object, and pays attention to the rational factors, understanding, accuracy and expressiveness of lines in shaping the body in depth. In the deep portrait stage of structure sketch's silent painting, when dealing with the relationship between subject and space, and the relationship between part and whole, rational thinking occupies a large proportion, but at the same time, the role of perceptual thinking can not be ignored, which easily leads to the dull picture and lack of vitality. In structure sketch's silent paintings, it is necessary to highlight the compactness of lines and the staggered rhythm.
Step 6: Arrangement and Adjustment
When we have finished the in-depth and meticulous description, we need to carry out the overall cleaning process to make the modeling more accurate, the shape thicker, and the overall effect of the picture more unified, summarized and vivid.
