Sketch cube course
First of all: before drawing a gypsum cube, do a good job of observation and analysis. Students need to learn what perspective is. This is crucial. If the perspective picture is correct, then the geometric shape of gypsum will be drawn correctly, and the visual effect will be comfortable.
First, the purpose of the long line is to compare, compare angles and accurately draw shapes. Extend two opposite lines indefinitely and you will find that they will cross together. This is perspective, which is near big and far small, near wide and far narrow. When drawing this step, you should also pay attention to the proportion and length of each side. Generally, the near side is long and the side is short. It is easier to draw a good sketch by grasping this rule.
Second, after laying the shape, it is to lay the tone and draw the relationship between light and shade.
1. First lay the dark side, one tone, and then lay the gray side. Pay attention to the contrast between the two tones.
2. On the dark side, distinguish the projection from the dark side of the geometric gypsum image itself, and then add a layer on the bright side to pave the background. So there are two levels of bright side and dark side.
3. Draw the intersection of light and dark, and add a gray face at the same time. Pay attention to open the screen to observe the overall effect and avoid the problem of "gray" and "greasy".
4. By analogy, enhance the picture effect step by step.
Third, draw some details, such as pits, bad corners, lining folds and so on. In order to make the picture more exciting.
Fourth, deeply depict and coordinate the overall relationship between light and shade.
5. Draw the rendering of gypsum cube.
