Digital Design of Product Packaging (Part 2)

3. Real-time realization of three-dimensional visualization The three-dimensional visualization technology uses computer-based three-dimensional graphics software to create a completely virtual three-dimensional space on the computer screen. In this virtual space, designers can directly perform various types of three-dimensional designs in three-dimensional fashion, such as interior design, product design, sculpture design, three-dimensional animation design, and so on. The two-dimensional CAD system can only help designers reduce the workload of manual design and drawing. The three-dimensional visualization technology can not only reflect people's rich creative results, but also can grasp the random chance results generated in the process of shape creation. Designers are particularly precious, and they can inspire people in the design of creative inspiration. Three-dimensional visualization technology can also be very simple to complete the real-time graphical editing and modification, operation is particularly convenient, can most directly reflect the designer's creative intentions.
The packaging itself is a spatial three-dimensional structure. The use of three-dimensional visualization technology to assist in design is the best choice. There are many three-dimensional software on the market, but the most frequently used is 3D studio MAX software. This software has many advantages. First, it has strong modeling capabilities, basic modeling and advanced modeling, which can provide technical support for the digital generation of product packaging structure design. Secondly, it has a superb material editing function. Users can build their own materials according to their needs. This is a rare application of technical support for product packaging visualization. We can make the graphics of the graphic design divided into corresponding files. After the 3D texture material is completed, the texture material is assigned to the corresponding structure surface according to the structural plane, and a virtual model of the 3D visualization of the product packaging is obtained after rendering. Certainly, after the material is specified, some parameter adjustments are necessary. This is because when the 3D studio MAX software generates the spatial structure plane, the “face” is positively and negatively controlled, and is controlled by the normal direction of the “face”; On the one hand, each structural plane has its own three-dimensional coordinate system. The three-dimensional coordinates of the material must be consistent with the coordinates of the "plane." If you do not make the corresponding parameter adjustment, some texture faces will not see the texture effect when rendering. Third, 3D Studio MAX software has good animation capabilities. If necessary, the product packaging design scene can be animated to dynamically display its three-dimensional effect.
The general steps for the 3D visualization of the digital design of the product packaging are: first use the 3D Studio MAX software to design and model the packaging structure; then, the 3D Studio MAX mapping material is used to divide the graphic image of the partitioned graphic image into each segmented graphic file. Third, use the minor object texture edit command to assign the texture materials of each structural surface to the corresponding structural surface, and adjust the parameters so that the visual effects are consistent with the design concept; fourth, adjust the output perspective of the effect image. , render output. Finally, the design of the output is evaluated. If it is not satisfied, it will be returned to the modification.
Third, concluding remark The digital design of the product packaging has many outstanding advantages compared with the traditional manual design, specifically manifested in:
* The design and creative space is more flexible and open;
* Designed materials and equipment are more simplified;
* Design changes and modifications to facilitate the design of the Express Express series;
* Design expression is easier and performance quality is higher; drawing generation is simpler and more accurate;
* It is convenient and easy to design and build files; information transmission is faster;
* More efficient design;
The essence of design is, in a sense, an iterative process of continuous improvement. Digital technology undoubtedly provides the most effective technology and method for designing quickly, easily, and accurately. It also enables companies to take advantage of competition. status. At the same time, it also freed the designer from the complicated manual labor, reduced the designer's design work intensity, and provided the most advanced technology for designing to adapt to the development of the times.
