Description

Technical Field

[0001] The present invention relates to the technical field of ice and snow effect drawing, and in particular to a method for drawing ice and snow effects. Background Art

[0002] Chinese painting is a traditional Chinese painting form. It uses a brush dipped in water, ink, and color to paint on silk or paper. It reflects the ancient people's understanding of nature, society, and all aspects related to them. It is one of the four arts of music, chess, calligraphy, and painting. In Chinese painting, tools and materials include brushes, ink, Chinese painting pigments, rice paper, silk, etc., and the subject matter is very broad, which can be divided into figures, landscapes, flowers and birds, etc. Chinese painting has unique characteristics in composition, brushwork, ink, and color application. The composition of Chinese painting also pays attention to "white as black". For color application, natural minerals or powders of plant and animal shells are mostly used. The effect of the inherent color of the object is pursued, and the changes in light and shadow are rarely shown. Ice and snow effect painting refers to the use of Chinese painting forms and specific techniques to show the texture and effect of ice and snow on canvas or paper. Specific painting methods usually include: basic description, adding gradients, detail portrayal, and highlight processing.

[0003] In the prior art, during the drawing of ice and snow effects, the reference pictures are usually not processed. However, there are many differences in details between the reference pictures and the real scenes, which makes it impossible to fully draw the real texture and light and shadow effects of ice and snow, thereby reducing the presentation effect of ice and snow drawing. For this reason, we propose a drawing method for ice and snow effects to solve the above problem. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that during the process of drawing ice and snow effects, the reference picture is usually not processed, and there are many detail differences between the reference picture and the real scene, which makes it impossible to fully draw the real texture and light and shadow effects of ice and snow, thereby reducing the presentation effect of ice and snow drawing. A method for drawing ice and snow effects is proposed to solve the problem.

[0005] The present application provides a method for drawing ice and snow effects using the following technical solutions:

[0006] A method for drawing an ice and snow effect comprises the following steps:

[0007] S1: Grind wood fiber into fine powder and mix it with glue, and heat and press it to form a drawing board;

[0008] S2: Select a location to observe ice and snow, take photos, analyze and observe the characteristics of ice and snow;

[0009] S3: Mix different colors and clean water according to proportion;

[0010] S4: Lay the rice paper on the drawing board and lay the base color;

[0011] S5: Draw a sketch of ice and snow on the background based on the processed ice and snow photos;

[0012] S6: performing light and shadow processing according to the light source direction of the processed ice and snow photo;

[0013] S7: Use brushes and spray cans to depict the texture and details of ice and snow;

[0014] S8: Observe the picture and adjust the color, light, shadow and texture to obtain the ice and snow effect picture.

[0015] Furthermore, in S1, the wood fiber fine powder is mixed with glue by a mixing mechanism, pressed and formed by a molding device under the action of heating and pressure, and dried and trimmed to become a density board with a thickness of 5-10 mm to obtain a drawing board.

[0016] Furthermore, in S2, the filming location is Heilongjiang Province, and photos of ice and snow at the filming location are taken with a high-definition camera, the ice and snow photos are uploaded to a computer, and the ice and snow photos are processed through image tools to restore the real ice and snow effect. The image processing process: white balance adjustment of the image to ensure that the white balance of the image is correct to restore the true color of the ice and snow, appropriately reduce the color saturation of the non-ice and snow part to make the ice and snow part prominent and natural, enhance the color contrast between the ice and snow and the surrounding environment, strengthen the highlight area on the surface of the ice and snow, add appropriate dark tones to the shadow part of the ice and snow to increase the sense of depth and three-dimensionality, ensure that the light source direction in the image is consistent, use sharpening tools or filters to enhance the details of the ice and snow surface, and ensure the natural integration of the ice and snow with the surrounding environment by adjusting the color, brightness or contrast of the background.

[0017] Furthermore, in S2, the shape and changes of ice and snow in the processed image are observed through image tools, the ice and snow surface reflects light to form highlights and shadows, the gloss and reflection effect of ice and snow are captured, and the interface between ice and snow and the surrounding environment is observed.

[0018] Furthermore, in S3, the Chinese painting plant color peptide cyan, gamboge and azure pigments are weight-proportioned at 4:1:1 by a proportioning mechanism, and the proportioned pigments are mixed by a mixing mechanism.

[0019] Furthermore, in S4, the drawing board is placed upright, rice paper is spread on the drawing board, and the four sides of the rice paper are fixed by transparent tape. The rice paper is cooked rice paper, and the length and width of the drawing board are larger than the painted work. The Chinese painting pigment is diluted with water, and the ratio is 10ml pigment: 1000ml water. The water is clean water at room temperature. A large wool soft brush is dipped in the adjusted color and the base color is brushed on the rice paper. Brush it evenly.

[0020] Further, in S5, when the base color on the rice paper is 50% dry, use a clean brush dipped in clean water to draw the outline of ice and snow covering the flowers, leaves, stems and trunks of plants on the base color, which will separate the original base color, and produce natural fluffy water stains on the edges of the objects, producing white traces like snow. When the base color on the rice paper is 80% dry, use a manual spray bottle filled with clean water and spray it into the objects depicted by the base color. The spray bottle is 20-30cm away from the picture. Stop after natural white water stains are formed on the parts of the depicted objects, producing a color and texture like falling snowflakes, achieving the granular effect of ice and snow on the objects. After the snowflakes are formed, water can be sprayed again, and the water drops will bloom on the rice paper and separate from the base color. The method to thicken the snow on the snow is to spray water repeatedly until it is completely dry, and determine the direction and intensity of the light source.

[0021] Furthermore, in S6, according to the direction and intensity of the light source, the brightness of the highlight part is enhanced by applying a base color with a brush dipped in clear water. Under the influence of gravity, the water causes the base color to sink, which increases the depth of the dark shadows, forming a natural color transition, thereby highlighting the three-dimensional effect of ice and snow.

[0022] Further, in S7, after the rice paper is completely dry, the various plants are outlined with a brush dipped in ink according to the ice and snow brushwork effects on the picture, and then colored, leaving the white snow part. The ink and pigment increase the layer of snow coverage, and the ice and snow picture is dried by a hair dryer at a drying temperature of 20-30°C.

[0023] Furthermore, in S8, the ice and snow picture is compared and analyzed with the snow scene photo through a comparison mechanism, and the color, light and shadow and texture of the ice and snow picture are adjusted through a brush to obtain an ice and snow effect picture, and the drawn ice and snow effect picture is recorded through a recording device, and the drawing skills are mastered through practice and comparison with the drawn ice and snow effect picture.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. This scheme grinds wood fiber into fine powder and mixes it with glue, and then heats and presses it to make a drawing board, which can ensure the firmness and stability of the drawing board, and has a waterproof effect, and is not easy to deform, thereby ensuring the drawing effect;

[0026] 2. This scheme uses the plant colors of Chinese painting: peptide blue, gamboge, and dawn red pigments in a certain proportion and uses them as the basic tones for drawing the shapes and outlines of ice and snow. This can effectively ensure the lightness and transparency of ice and snow, avoid the monotony of ice and snow colors, and at the same time, enhance the highlights and layers through the depth of the colors, and use cold tones to set off the cold atmosphere of ice and snow, which effectively improves the texture and dynamics of ice and snow.

[0027] 3. This solution uses image tools to process ice and snow reference images, accurately restore the real effect of ice and snow, and then fully draw the real texture and light and shadow effects of ice and snow. At the same time, it uses the perspective principle to simulate the sense of distance between ice and snow and the observer, making the drawing more profound.

[0028] During the drawing process, the present invention accurately restores the real effect of ice and snow by processing the reference picture, and then can fully draw the real texture and light and shadow effects of ice and snow, effectively improving the presentation effect of ice and snow drawing. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 This is a flow chart of a method for drawing ice and snow effects proposed by the present invention. DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Embodiment 1

[0032] Reference Figure 1 , a method for drawing ice and snow effects, comprising the following steps:

[0033] S1: Grind wood fiber into fine powder and mix it with glue, and heat and press it to form a drawing board;

[0034] S2: Select a location to observe ice and snow, take photos, analyze and observe the characteristics of ice and snow;

[0035] S3: Mix different colors and clean water according to proportion;

[0036] S4: Lay the rice paper on the drawing board and lay the base color;

[0037] S5: Draw a sketch of ice and snow on the background based on the processed ice and snow photos;

[0038] S6: performing light and shadow processing according to the light source direction of the processed ice and snow photo;

[0039] S7: Use brushes and spray cans to depict the texture and details of ice and snow;

[0040] S8: Observe the picture and adjust the color, light, shadow and texture to obtain the ice and snow effect picture.

[0041] In this embodiment, in S1, wood fiber fine powder is mixed with glue by a mixing mechanism, pressed and formed by a molding device under the action of heating and pressure, and dried and trimmed to become a density board with a thickness of 5-10 mm to obtain a drawing board.

[0042] In this embodiment, in S2, the filming location is Heilongjiang Province, and a high-definition camera is used to take photos of ice and snow at the filming location, the ice and snow photos are uploaded to a computer, and the ice and snow photos are processed by a picture tool to restore the real ice and snow effect. The picture processing process: adjust the white balance of the picture to ensure that the white balance of the picture is correct to restore the real color of the ice and snow, appropriately reduce the color saturation of the non-ice and snow part to make the ice and snow part prominent and natural, enhance the color contrast between the ice and snow and the surrounding environment, strengthen the highlight area on the surface of the ice and snow, add appropriate dark tones to the shadow part of the ice and snow to increase the sense of depth and three-dimensionality, ensure that the light source direction in the picture is consistent, use sharpening tools or filters to enhance the details of the ice and snow surface, and ensure that the ice and snow are naturally integrated with the surrounding environment by adjusting the color, brightness or contrast of the background. Observe the shape and changes of ice and snow in the processed picture through the picture tool. The ice and snow surface reflects light to form highlights and shadows, captures the gloss and reflection effect of ice and snow, and observes the junction of ice and snow with the surrounding environment. The picture tool uses professional image editing software (such as Adobe Photoshop, Lightroom, etc.).

[0043] In this embodiment, in S3, the Chinese painting plant color peptide cyan, gamboge and azure pigments are mixed by weight in a ratio of 4:1:1 by a proportioning mechanism, and the proportioned pigments are mixed by a mixing mechanism.

[0044] In this embodiment, in S4, the drawing board is placed upright, rice paper is spread on the drawing board, and the four sides of the rice paper are fixed by transparent tape. The rice paper is cooked rice paper, and the length and width of the drawing board are larger than the painted work. The Chinese painting pigment is diluted with water, and the ratio is 10ml pigment: 1000ml water. The water is clean water at room temperature. A large wool soft brush is dipped in the adjusted color, and the base color is brushed on the rice paper. Brush it evenly.

[0045] In this embodiment, in S5, when the base color on the rice paper is 50% dry, use a clean brush dipped in clean water to outline the shapes of plant flowers, leaves, stems, and trunks. The original base color will be separated where the water outlines, and natural fluffy water stains will be produced on the edge of the image, producing white traces like snow. When the base color on the rice paper is 80% dry, use a manual spray pot filled with clean water and spray it into the image depicted by the base color. The spray pot is 20-30cm away from the picture. Stop after natural white water stains are formed on the part of the image, producing a color and texture like falling snowflakes, achieving the effect of ice and snow. To create the granular effect on the object, after the snowflakes are formed, you can spray water again. The water drops will spread out on the rice paper and separate from the background color. The way to thicken the snow on the snow ground is to spray water repeatedly until it is completely dry. Use delicate brushstrokes to depict the texture of ice and snow, such as ice crystal particles, fine snowflakes, etc. Add details to the edge or junction of ice and snow, such as cracks in ice cubes, ups and downs of snow piles, etc. to increase the realism of the picture. Pay attention to the junction of ice and snow with the surrounding environment, such as the edge of ice cubes, footprints or wind marks on the snow, and determine the direction and intensity of the light source.

[0046] In this embodiment, in S6, according to the direction and intensity of the light source, the brightness of the strong highlight part is increased by applying the base color with a brush dipped in a clear water level to present a sense of hierarchy, the three-dimensional sense and texture of the ice and snow are enhanced by the contrast between the highlight and the shadow, the distance and nearness of the ice and snow are distinguished by the depth of color, the intensity of light and shadow, and the density of texture, so that the picture has more depth, and the perspective principle is used to simulate the sense of distance between the ice and snow and the observer;

[0047] The specific method of perspective principle is:

[0048] 1. Linear perspective (one-point perspective, two-point perspective, three-point perspective)

[0049] One-point perspective: suitable for depicting flat ground covered with snow or snowy scenery in the distance. Choose a vanishing point and converge all parallel lines (such as the edge of the snow, the ridgeline in the distance) to this point to create a sense of distance;

[0050] Two-point perspective: When the snow scene contains two main vanishing directions (such as mountain roads and river valleys), use two-point perspective. The two vanishing points are located on the left and right sides of the picture, and parallel lines converge to these two points, enhancing the depth and width of the space;

[0051] Three-point perspective: For more complex snow and ice scenes or scenes with large pitch angles, a third vanishing point can be introduced. It is usually used to express scenes from a high altitude or from a low angle, such as looking down at the snowfield from the top of a mountain or looking up at a snowy mountain.

[0052] 2. Atmospheric perspective (color perspective, light and dark perspective)

[0053] Color perspective: As the distance increases, the color of ice and snow will gradually become lighter and colder, and the contrast will decrease. Snow and ice close to you may appear bright white or light blue, while snow and ice far away may blend into the ambient color and become more blurred and light blue;

[0054] Chiaroscuro: Snow and ice in the distance will appear darker due to atmospheric scattering and light attenuation. This effect can be simulated by reducing the light-shadow contrast in the distance and increasing the blurriness. Meanwhile, snow and ice in the near distance may be bright due to direct sunlight, forming a strong chiaroscuro contrast.

[0055] 3. Size Perspective

[0056] In perspective, as the distance between an object and the observer increases, its visual size gradually decreases. Therefore, when drawing a snowy scene, distant mountains, trees, snow piles, etc. should be drawn smaller than those nearby to create a sense of distance;

[0057] 4. Detail Perspective

[0058] The ice and snow in the near distance can be drawn more meticulously, including the texture of snow particles, the glitter of ice crystals, etc., while the ice and snow in the far distance can be simplified, with fewer details, and presented in a blurred and generalized way, thus strengthening the contrast between near and far.

[0059] In this embodiment, in S7, after the rice paper is completely dry, the fine brushwork and freehand brushwork of Chinese painting are used according to the ice and snow brushwork effect on the picture. A brush is dipped in ink to outline various plants, and then colored, leaving the white snow part. The ink and pigment increase the layer of snow coverage. The ice and snow picture is dried by a hair dryer at a drying temperature of 20°C.

[0060] In this embodiment, in S8, the ice and snow picture is compared and analyzed with the snow scene photo through a comparison mechanism to find out the deficiencies and adjust the color, light and shadow and texture of the ice and snow picture through a brush to obtain an ice and snow effect picture. The drawn ice and snow effect picture is recorded through a recording device, and the drawing skills are mastered through practice and comparison with the drawn ice and snow effect picture.

[0072] In this embodiment, in S5, by adopting a two-color technique, according to the direction and intensity of the light source, the brush is dipped in water and lightly touched to the paper surface to enhance the brightness of the highlight part. Under the influence of gravity, the water causes the base color to sink and increases the depth of the dark shadows, forming a natural color transition. Therefore, the brushstrokes will present a natural gradient effect. By adjusting the length and strength of the brush tip, the width of the brushstroke and the degree of color mixing can be controlled to obtain different ice and snow effects.

[0085] In this embodiment, in S9, the foreground plants are depicted by dry brush and Chinese painting lines, and the brush is used to make slight adjustments. Finally, the picture is allowed to dry naturally. The realism and three-dimensional sense of the ice and snow scene can be enhanced by adding details.
