hand drawing Skills and Drawing Process

When you are in hand drawing, you should focus on the expression of modeling, color and texture, and also pay attention to design ideas and composition layout. Let's follow me to learn about hand drawing's skills and drawing process, hoping to help you! Hand drawing's skill

1. Conception modeling

First, we should use perspective law to express the structure of objects and build a spatial framework, and then use artistic methods to express light and shade, color and texture, and finally complete the spatial representation diagram, thus reflecting the designer's intention. In the process of drawing modeling, the emphasis is on the representation of perspective. It is not enough to express the stereoscopic effect with a single line. In order to strengthen the stereoscopic effect, the relationship between light and shade must be used. In the performance of hand drawing, the application of three major aspects and five major tones in sketch can be summarized and simplified according to the needs of design effect. In the actual design performance, you should choose complex and general expression methods according to the different uses of renderings, so as to express your design ideas more clearly.

2. Grasp the colors

The colors of general renderings should be concise, general and vivid, and reduce the complexity of colors. In order to enhance the artistic effect, some color renderings can be represented by colored paper as the background color. First, the colors are uniform, second, the painting time is saved, and third, the colors can be well unified to enhance the painting and interest.

when using color to express the effect diagram, we should not only express the relationship between colors and the light and shade of objects, but also pay attention to the texture effect of different materials. According to the characteristics of different surface materials, the corresponding pen-carrying methods should be used. If the surface texture is not obvious, the pen can be kept in the same direction, and the pen for coloring should have speed. Clean and neat, and the dark part can be painted with changing strokes, and the color is different from cold and warm.

3. Pursuit of texture

In art, the realism of grasping different objects with different skills is called texture. The expression method of texture plays a great role in indoor hand drawing. The purpose of studying performance techniques is to make the renderings of design results more real and convincing. The natural characteristics of different substances are called natural texture, such as air, water, rocks, bamboo and so on; The performance feeling after artificial treatment is called artificial texture, such as brick, ceramic, glass, cloth, plastic and so on. Different textures give people a variety of feelings such as softness, reality, smoothness, toughness, transparency and turbidity.

(1) shows metallic texture. The transition between light and shade is soft, and the contrast is strong under the irradiation of light. When showing the surface with strong gloss, attention should be paid to the treatment of highlights, reflections and reflections, and the brush strokes should be parallel and neat, which can be expressed by a ruler.

(2) It represents the texture of transparent materials. Glass (colored, colorless) should master the polygonal relationship between the reflective part and the transmitted light. Transparent materials are basically represented by the background color of the environment and the color of light irradiation.

(3) It represents the wood texture. Mainly the performance of wood grain, according to the variety of wood. First, apply a layer of wood background color, and then draw wood grain lines by hand. The wood grain lines are shallow first and then deep, so that the wood texture is natural and smooth.

(4) the stone texture. Stone is widely used indoors. Its texture is hard, smooth and bright. When it is displayed, it should be painted with a thin layer of background color according to the inherent color of the stone, leaving high light and reflection, and then the texture of the stone should be properly drawn with Gou Xianbi.

(5) It represents the texture of leather and plastic. Leather and plastic surfaces are smooth and non-reflective, between glass and wood. They are not as bright as glass, but shiny compared with wood. The transition between light and shade is slow, and the coloring should be natural and uniform.

4. Layout of ideas

Correctly grasping the design idea and conception, and deeply understanding the design intention are the primary focus of learning the representation technique. Therefore, we must take improving our professional theoretical knowledge and cultural and artistic accomplishment, and cultivating creative thinking ability and profound understanding ability as an important training purpose throughout our study.

Composition is an indispensable initial performance stage in any painting, and the decorative design performance chart is no exception. The so-called composition is to organically combine many modeling elements on the picture, and arrange them in appropriate positions in the picture according to the theme required by the design, so as to form a picture that is both opposite and unified, so as to achieve a visual and psychological balance.

As a future decoration designer, hand drawing is a professional language. Compared with computer drawing, it is efficient and expressive, so it can't be replaced by computers and can't be discarded. Hand-painted techniques should be maintained and developed, and more attention should be paid to the accumulation of experience in hand-painted sketches and creative performance analysis charts. In addition, the communication medium between designers and computer draftsmen also lies in sketches, which is essential. With the continuous improvement of owners' aesthetic level and cultural accomplishment, it is not far off to report or exchange ideas directly with sketches. Therefore, the artistic characteristics and advantages of hand-drawn design determine its position and function in expressive design, and its expressive skills and methods are full of natural artistic temperament, so the expression of artistic beauty between design rationality and artistic freedom has become the goal pursued by designers. Designers' performance skills and artistic style are matured through constant tempering and accumulation in practice, so the understanding and mastery of skills and methods are the basis for the maturity of performance techniques, and the effect of hand-painted performance can reach the level of both form and spirit, which is the highest realm that art endows environmental images with spirit and life, and also the embodiment of artistic quality and value. Specification for rendering

1. Rendering process:

Market or customer service department places an order (rendering task list). Sign the task list and fill in the schedule

The model drawing supervisor confirms and signs and sends samples to Party A

Adjust and send samples to Party A to confirm the model according to Party A

Paste the material rendering sample supervisor to confirm and sign and send samples to Party A

Adjust and render samples and pictures of local important materials according to Party A's opinions and submit them to Party A for confirmation, and submit them to the supervisor for confirmation for later stage

Deliver it to Party A for local adjustment, send it to Party A to notify the marketing department to complete the feedback from the marketing department and fill in the task list for completing the renderings.

Submit it to the department head for archiving, submit the task list at the end of the month and check the drawing backup file.

2. Overall principle:

1. Put all the designer's tasks in the work tray folder, and the folder is named according to the year, month, place and project name. (19.11.11XXXXXX)

2. An renderings project file must contain model folder (original model and modified model cannot be replaced, material folder (including all materials), rendering file (rendered TIF picture and TGA channel folder) and photon file.

3. The model mapping (referring to the material texture and mapping coordinates) is not completed, or it is forbidden to start the vr renderer without the approval of the supervisor.

4. All monomer models, materials, rendered drawings and photons must be real names.

5. The way to prevent the accumulation of wood is to build a model. If a single object consists of multiple parts, it must be grouped;

Third, the model requires

(1) The uniform size of the building model is millimeters (mm).

(2) return to zero after importing CAD files into MAX;

(3) The same object must be copied by association;

(4) To grasp the scale accurately, it must be consistent with the actual object size;

(4) Try to replace the curve with a broken line;

(5) When building transparent mapped objects, just use a piece;

(6) When building a large number of objects such as window frames, try to use one bar on the same line;

(7) At the beginning, try to control the number of segments and delete the invisible faces as much as possible;

(8) The terrain is made into pieces, and the side faces are sealed with kerbs, leaving no bottom faces;

(9) * * faces are not allowed (walls made of different materials are easy to hand over * * * faces). [1](11) Handover shall be in perfect harmony and aligned.

(12) Grasp the number of model faces: ordinary monomer? 111 objects and 51,111 surfaces. Complex monomer? Less than 311 objects, less than 311,111 surfaces (25% of European buildings with complex shapes). Bird's eye view of the group? Below 1111 objects, below 2 million surfaces.

renderings are a more general statement. We subdivide it into architectural renderings, decoration renderings, industrial product renderings, etc. Here we focus on architectural renderings and decoration renderings. Understanding architectural renderings can be divided into

1. Advertising renderings: This rendering method focuses on the environment and greening around the building, and has little requirements for the performance of the building itself. Then, more emphasis is put on the color of the inner renderings, especially in the contrast of cold and warm colors, the color saturation of the whole picture, and the contrast of light and dark are relatively more artistic and idealized. Most of the renderings in this area are favored by general builders and can be accepted by ordinary people. The advantage is that the visual effect is very good and it is easy to attract buyers. The disadvantage is that the credibility is low, and often the developers can't achieve the expected effect on the renderings.

2. photo renderings: this kind of expression method focuses on the true reproduction of the whole building. Usually, this kind of renderings are gray, and the requirements for the authenticity of the surrounding environment are strict, so as to pursue photo effects as much as possible. The production method generally needs to be synthesized through a large number of real digital pictures. Advantages: high credibility. Through it, you can basically imagine the effect of the whole building after completion. Disadvantages: it is difficult to make and the visual impact is not very good. However, this kind of effect expression technique will be an absolute development direction in a year or two, for the simple reason that people gradually don't believe those perfect effect pictures.

3. Structural renderings: The expressive techniques of this kind of renderings are mainly aimed at the intellectuals who have received higher education and the architects themselves, and its focus is on trying to reflect the beauty of the building itself. Mr. Lu Zhenggang, the general manager of Beijing Crystal Stone, once said that there are two situations in the expression of architectural roaming animation. 1. It is realistic, and the main pursuit of this kind is to be as close to real life as possible. 2. Architectural. This category is mainly used to reflect the architect's creation in designing a building? Conception? Design? In the process of completion, this kind of performance does not need blue sky, wide land, many people and cars, nor does it need many environmental flowers and plants. It just shows the building itself.

The same is true in the performance of static renderings. Our focus is to reflect the beauty of the building itself, so the sky, background, trees and so on can be dispensed with. This kind of renderings are mainly used for bidding. Decoration renderings are relatively much simpler. We only need to make them according to a certain proportion according to the scheme provided by the designer. We only need the level of the main space when lighting, because the indoor space is not as wide as the outdoor space, and it is easy to make the whole space dull and unchanged when lighting. Another point in the performance of decoration renderings is that the whole picture should be as warm as possible. ;
