Now 1, computer art design is widely used, and the number of people engaged in this work has greatly increased. Universities have set up computer art design courses. 2. Artists began to learn to create by directly operating computers instead of relying on programmers. 3. With the decrease of screen images, computers began to have the function of expressing stereoscopic and organic images, and exhibitions of computer art and design works were held in art galleries.
As a young science, computer art packaging design has developed rapidly and has great potential. In the concept or imagination of ordinary people, computer-designed art packaging works are basically the same as ordinary industrial drawings, right? In fact, computers can not only accurately design and produce effects that people can imagine but are difficult to express, but also design and produce effects that people can't imagine and therefore can't express. To complete an artistic packaging design by computer, there must be two computer design systems working in series, namely "color design system and graphic design system". The former is to adjust and change the color on the basis of graphic design, while the latter is to design the graphic composition layout and modeling, and generate an intermediate work with any color. In order to meet the requirements of designers. In addition, the computer has a huge storage system, including the storage of various elements and colors. Element storage system can not only contain various basic forms, such as points, lines, surfaces, squares, circles, triangles, etc. , including two-dimensional and three-dimensional geometry. It can also include various complex natural forms, such as portraits, animal patterns, landscapes and some excellent design works. During the design process, these elements can be translated, rotated, scaled, dislocated, completely changed, etc. According to the designer's instructions, any graphics needed by the designer can be generated. The computer's color storage system is considerable, and the storage capacity varies with the computer model and software. Just click on the displayed color block to select the color. At the current level, it can store thousands of kinds, many of which can exceed several gigabytes.
In addition, the computer system also has the "interactive function" (also known as man-machine dialogue function) that the human brain controls the computer. In the whole process of art design, the human brain is in a leading and dominant position, and the computer is only a tool to assist the human brain to play its subjective initiative and wisdom more effectively. The program is designed by people, so computer art design is only one of the special technical means and tools. According to these special means, the computer can quickly carry out image trimming on the display. Man-machine dialogue can be carried out on the keyboard, which is a very useful interactive device and can easily provide designers' opinions to the program. The more convenient means to talk with the keyboard are the handwriting board and the pressure-sensitive pen, which are similar to ordinary pens. Is this pen all right? 0? 3? 0? Writing brush, chalk, carbon pen, crayon, chalk, oil. 0? 3? 0? 2 strokes ",etc., very suitable for designers. It is an electromagnetic wireless mouse, whose function is to make users draw more conveniently and comfortably. 0? 3? 0? 2, in order to adapt to the habit of users moving the cursor with the mouse in the past. But the electromagnetic wireless mouse can only be put in the picture? 0? 3? 0? When the mouse is not used, it will automatically sleep, and it will be used when drawing when necessary. 0? 3? 0? 2. Tap on the board to activate the mouse. So designers can use it to modify patterns and adjust colors directly on the display screen or draw directly? 0? 2。 If the designer wants to compare paintings? 0? When the graphics on two sides are filled with colors, you can get satisfactory results as long as you click on the desired color and the graphic position that needs to be filled with colors on the graphics software with a pressure-sensitive pen. Draw with a pressure-sensitive pen? 0? Fast speed, high efficiency and simple operation technology can be described as a stroke of genius. However, after all, the computer system is a tool that people make and manipulate, and it only executes programs mechanically. Any sensitive or even "smart" response made with the change of external conditions in the execution process is the result of the programmer's pre-arrangement.
At present, there are usually two methods for packaging design by computer. The first type: the designer first conceives a sketch or painting? 0? 2 sides, then scan them, finally get a visual image on the display screen, and then create a design. The second method: first, the computer generates a random graph on the display screen, and then the designer modifies, adjusts and supplements it on the basis of this graph until it is satisfied.
In order to adapt to and master the thinking method in images, it is necessary to train and reform the analytical, comprehensive and professional thinking ability of sensory organs and brain.
One of the directional training of design is the training of observation ability, that is, to have a "design vision". Training keen observation ability is more important than imparting a lot of knowledge. Nowadays, with the development of modern science and technology, people's artistic vision has expanded to a new stage in both the macro world and the micro world. There are many phenomena in life, ordinary people may "turn a blind eye", but for designers with "unique vision", they are likely to get inspiration and create wonderful packaging design works. Life and nature provide an inexhaustible source for designers, and the design materials are around you. The key is whether they can be found or applied. Da Vinci said; "Find your own creative material around you, observe the grotesque shape of white clouds, and observe the mildew on the neighbor's wall." "Observation" belongs to a kind of "intentional attention" in psychology and is a positive thinking activity, which is mainly manifested in: professionalism, curiosity and purpose.
Imagination is the second kind of orientation training, which is the training of imagination ability. The so-called "design brain", imagination is the central link, through imagination, we can use perceived materials (images, colors, texture structure) to create, and the conception intention of a design work is based on imagination. Imagination is very important in the knowledge structure of designers. Einstein said: "Imagination is more important than knowledge, because knowledge is limited, and imagination summarizes everything in the world, promotes progress and is the source of knowledge evolution." It is a "real factor" in design. There are two kinds of imagination: recreating imagination and creating imagination. Reconstruction imagination is supplemented by creative imagination, which needs to be based on reconstruction imagination.
Inspiration is that a designer sometimes thinks hard and tries to find the ideal composition intention again and again, but sometimes his thoughts are suddenly enlightened, his thoughts are smooth and imaginative. It's called inspiration. Psychologists have made various analyses of "inspiration", and most people think that:
1, "inspiration" is a special mental state;
2. "Inspiration" has three characteristics: contingency, suddenness and transience;
3. "Inspiration" is produced when attention is completely focused on artistic creation;
4. "Inspiration" is the best time domain for creation. At this time, thinking activities are the most active and creativity is the most effective. Lie Bin put it well: "Inspiration" is the reward for hard work.
Therefore, computer programming imitates the characteristics of many traditional tools and brings a new modeling language for design. Create a human experience? 0? 2. The inspection can continue; With the further development of computer, it has its own unique brand-new tools and means of expression. You can also feel the interaction between people and images that traditional tools cannot bring. On the other hand, when designers give computers a lot of freedom to create automatically through programs, the effect is often unexpected. Computer has powerful modeling ability, which can not only simulate complex spatial surfaces, but also connect multiple entities for operations such as splitting or merging, differentiating and intersecting, thus making the entities created more diversified. The current computer packaging design is to combine the two poles of art and science and enrich the world of contemporary plastic arts with a brand-new attitude. Secondly, computers have trained a new generation of packaging designers. When designers use the computer system to work, they can not only give full play to the advantages of the system in solving problems, but also work at a higher level. Traditional design tools and design tools in the information age. Pencil, marker, watercolor pen, chalk, writing brush, gouache pigment, watercolor pigment, ruler, triangular ruler, curve board, etc. , desktop computers and color printers. In the traditional division of labor, from design conception to production is divided into multiple stages, and designers should participate in the work of each stage. With the introduction of computer-aided design, the work that can be described in a certain language and embodied in rules, such as drawing, which occupies a large part of the design workload, has been replaced by computers, which on the other hand highlights the creative ability of designers and makes creation, evaluation and organizational design the main work content of designers. In other words, designers can work at a higher level and get the support of computers at that level. Packaging itself is a three-dimensional structure, and it is the best choice to use three-dimensional visualization technology to assist design. Three-dimensional visualization technology can not only reflect people's rich creative achievements, but also grasp the random and accidental results produced in the process of form creation, which is particularly precious to designers and can inspire people's design and creation. Three-dimensional visualization technology can also easily complete real-time graphic editing? 0? 4? 0? And the operation is particularly convenient, which can directly reflect the creative intention of the designer.
With the development of science and technology, computer art design has made new contributions to the new skills of packaging design, and aesthetic works about it have been published continuously. Some people call computer design "another revolution in the history of modern art" Frank, a German computer artist, said that computer art is "like a bridge between two cultures (science and art)" and is "the perfect crystallization of mathematics, computer science and aesthetics". In a word, the development of computer art design will certainly bring fascinating progress to the field of art design. It is also one of the most modern artistic means in the world.
