The perspective principle is widely used in structure sketch, so the requirements for the picture are relatively rational and rigorous, which is the most direct way for us to contact and understand the structure.
2. The ultimate goal of sketching a structure is to understand and analyze the structure. Therefore, simple and clear lines are generally used when drawing, which requires students to have a strong sense of three-dimensional space, because we should make still life transparent and draw both visible and invisible types.
What structure sketch wants to show is the structural relationship of objects, explaining what the form is, a part of it or how this part is combined. These essential features should be refined and summarized from the specific reality, and don't indulge in some small details.
3. The later works, though painted with some colors, also belong to structure sketch. We can see that the lines used in the picture are very accurate and definite, and the main structure and picture relationship are well expressed. Some lines with large strokes are also used to distinguish the dark side from the bright side.
Extended data:
Learning from structure sketch is not an end, but a means. Structure sketch didn't draw all the objects into geometric piles. We analyze the structure in order to understand the object more clearly, so as to have a clear understanding of it and express the object better.
As a design major, it is very important to express and understand objects, and the understanding and expression of structural forms can help us complete the design idea perfectly.
Structure sketch is dominated by lines. Accurate, powerful and beautiful lines can make the picture full of vitality and enrich people's visual effects.
Observation method:
1) general observation: summarize complex objects with simple geometric figures, summarize irregular edges into straight lines, and feel the overall shape of the objects.
2) Stereoscopic observation: Sketch is a plastic art, and its basic feature is to represent a three-dimensional or multi-dimensional image on the plane of two-dimensional space, correctly analyze the perspective direction of the three-dimensional object image, and understand the spatial relationship when it is expressed on the plane.
3) Observation in connection: Each group of objects is an inseparable whole, and the whole and parts of things are intrinsically connected. Adjacent edges and corresponding edges of objects need to be connected and compared to distinguish them, and comparison means looking at them in connection. Only by repeated comparison can we accurately express the characteristics of things.
4) imaginative observation: "naturally, I learned it from foreign teachers", that is to say, it is not enough to simply reproduce the surface of things. Only by carefully observing the object, feeling the object, imagining the object and understanding all the contents of the object can we achieve the highest goal of artistic creation.
