Showing the sense of three-dimensional and layering on the
Hand-painted wallpaper can make the picture more vivid and rich, and enhance the visual effect. Here are some ways and tricks:
(1) Use color
Contrast of light and shade: by processing the light and shade of different sides of the object to show the three-dimensional sense. For example, draw a sphere, the color of the light surface is brighter, you can use a light tone such as white or light yellow to show; The backlit side is dark in color, use a dark color such as brown or dark blue. In the transition area, the light and dark tones can be naturally integrated through gradual changes, making the sphere look rounded and three-dimensional. For scenes in the wallpaper, such as mountain scenery, distant peaks can be expressed in lighter blue and gray, and the colors of the mountains closer to the foreground gradually deepen, creating a sense of spatial hierarchy through this contrast of light and dark.
Color cold and warm: The use of cold and warm tone differences can also enhance the sense of three-dimensional and layered. Warm colors such as red, orange, etc., usually give people the feeling of protruding forward, while cool colors such as blue, green, etc., have the visual effect of retreating. When painting a forest wallpaper, you can paint the trees in the foreground with warm shades of green to make them more prominent; The trees in the background gradually transition to a cool shade of green, which creates the depth and layering of the forest.
(2) Line use
Outline line: Clear and clear outline line can outline the shape of the object, so that it has a certain three-dimensional sense on the plane. When drawing objects, pay attention to the thickness and weight of the lines. For example, to draw a vase, the outline of the mouth and bottom of the bottle can be appropriately bold to emphasize its shape; In the round and shaded parts of the vase, the lines can be slightly accentuated to make the object look more three-dimensional. For complex scenes, such as urban street scenes, the outline of the building can be treated differently according to the distance and importance, the distant outline of the building is thinner and lighter, and the near outline of the building is thicker and clearer, so as to express the sense of space hierarchy.
Internal lines: Adding some auxiliary lines inside the object can express its structure and three-dimensional sense. For example, when painting a fruit, you can draw some fine textured lines on the skin, and the direction and density of these lines are determined according to the shape of the fruit and the lighting conditions. On the receiving surface, the texture lines can be relatively sparse and shallow. In the backlit and shaded areas, the texture lines can be properly encrypted and deepened, which can make the fruit look more realistic and three-dimensional. For the characters in the wallpaper, add some lines to the folds of the clothes, which can show the texture of the clothes and the dynamics of the human body, and enhance the layer of the picture.
(3) The principle of perspective
One-point perspective: Often used to represent indoor scenes or images with a clear depth direction. Identify a vanishing point where all parallel lines converge. For example, drawing the wallpaper of a room, the lines of the wall, the lines of the floor and the lines of the furniture should be drawn in accordance with the perspective principle, so that the audience can feel the depth and three-dimensional sense of space. The near object should be drawn larger and clearer, and the distant object gradually becomes smaller and fuzzy, and the sense of hierarchy can be expressed through this change in size and clarity.
Two-point perspective: applies to the situation where both sides of a building or object can be seen. Determine two vanishing points in the screen, and the left and right groups of parallel lines converge to the two vanishing points respectively. When painting the wallpaper of a tall building, the use of two-point perspective can make the tall building look more magnificent, and at the same time, through the size and position changes of different floors, as well as the treatment of details such as Windows, show the sense of three-dimensional and hierarchical sense of the building.
(4) Superposition techniques
Pigment superposition: In the painting process, you can use multiple superposition of pigments to express the sense of three-dimensional and layered. Draw a base color first, and then gradually overlay other colors on top, each overlay color can be adjusted as needed. For example, to paint a flower, first use a light pink as the base color, and then overlay a slightly darker red on the tip of the petal and the shaded part to make the petal look three-dimensional and layered. For complex scenes, such as seascape wallpaper, you can first draw a blue sea background color, and then superimpose white pigments on the top of the wave and the part of the sun, to show the ups and downs of the wave and light and shadow effect, and enhance the layer of the picture.
Material overlay: In addition to pigment overlay, different materials can also be used to overlay to create a sense of three-dimensional and layering. For example, when painting a wallpaper with a retro texture, you can draw the basic pattern and color on the wall first, and then paste some gauze, paper or other texture materials on it, and then paint or dye on these materials to make the picture have a rich texture and layer. Or use gold foil, silver foil and other materials to embellish the picture, increase the luster and three-dimensional sense of the picture.
Through the comprehensive application of the above methods, the three-dimensional and layered sense can be effectively displayed on the hand-painted wallpaper, making the wallpaper more artistic appeal and visual impact, and creating a unique and wonderful atmosphere for the space.
