Digital design of the hottest product packaging

Digital design of product packaging (Part 2)

3. Real time realization of three-dimensional visualization

three dimensional visualization technology is to use the three-dimensional graphics software in the computer to establish a completely virtual three-dimensional space on the computer screen. In this virtual space, designers can directly carry out various types of three-dimensional design in three-dimensional way, such as interior design, product design, sculpture design, three-dimensional animation design and so on. Two dimensional CAD system can only help designers reduce the workload of manual design and drawing, while three-dimensional visualization technology can not only reflect people's rich creative results; It can better grasp the random and accidental results produced in the process of form creation, which are particularly valuable for designers. It can inspire people in design and creation. 3D visualization technology can also be very simple to complete real-time visualization and modification, which is particularly convenient to operate, and can most directly reflect the designer's creative intention

packaging itself is a spatial three-dimensional structure, and using three-dimensional visualization technology to assist design is the best choice. At present, there are many 3D software on the market, but the most frequently used is 3D Studio MAX software. This software has many advantages. Firstly, it has strong modeling function, including basic modeling and advanced modeling, which can provide technical support for the digital generation of product packaging structure design. Secondly, it has super material function. Users can build their own materials according to their needs. This is a rare application technical support for the visual generation of product packaging. We can make the segmented files of graphic design graphics into corresponding three-dimensional mapping materials. After the structural modeling is completed, according to structure 2 The liquid medium in the low-temperature tank 1 generally selects alcohol or frozen liquid level, and assigns the mapping materials to the corresponding structural planes respectively. After rendering, the three-dimensional visual virtual model of product packaging can be obtained. Of course, after the material is specified, it is necessary to adjust some parameters, because when 3D Studio MAX software generates the spatial structural surface, the "surface" can be divided into positive and negative, and is controlled by the normal direction of the "surface"; On the other hand, each structural surface has its own three-dimensional coordinate system, and the three-dimensional coordinates of the material must be consistent with the coordinates of the "surface". If you do not make corresponding parameter adjustments, some structural surfaces will not see the mapping effect during rendering. Third, 3D Studio MAX software has good animation function. If necessary, the scene of product packaging design can be animated to dynamically display its three-dimensional effect

the general steps of 3D visual generation of digital design of product packaging are as follows: first, use 3D Studio MAX software to design and model the packaging structure; Then, the segmented graphic files of graphic design graphics are made of mapping materials of 3D Studio MAX; Third, use the secondary object mapping command to assign the mapping materials of each structural surface to the corresponding structural surface, and adjust the parameters to make its visual effect consistent with its design concept; Fourth, adjust the output angle of the rendering and render the output. Finally, the output effect is designed and evaluated. If you are not satisfied, you can choose regenerated EVA, Poe and polyolefin elastomer to toughen and return to modification

III. conclusion

compared with the traditional manual design, the digital design of product packaging has many outstanding advantages, so the shaft sleeve should be removed, which is specifically reflected in:

* the design creative space is more flexible and open

* the materials and equipment used in the design are more simplified

* design changes and modifications simple express series design generation is more convenient

* the design expression is simpler and the performance quality is higher; The generation of drawings is simpler and more accurate

* the design is easy to file; Information transmission is faster

* higher design efficiency
