Dyeing involves fixing a dye on a cloth, or creating a dyeing pattern. Because dyeing patterns depend on the physical properties of fibers, dyes, and dyeing technique that are employed, predicting a finished dyeing pattern is difficult even for artisans. Because dyeing is an irreversible phenomenon that requires a lot of time, to accurately predict a completed pattern would improve the efficiency of dyeing and reduce its costs. In this paper, we propose a digital method for designing dyeing patterns based on a simulation of the dyeing process. Dyeing experiments was conducted to model dyeing process accurately. From experiments, we defined the dyeing process is combination of two phenomena: capillary phenomenon and diffusion phenomenon. In the proposed method, integrated these two phenomena by using the cellular automaton method and generate dyeing patterns that produce different results depending on the pattern-generating parameters. The thickness of yarn and spaces between yarns in fabric is not uniform because of the influence of spinning and weaving. Therefore, in the proposed method, we use the fluctuation property, which is inherent in nature, to generate a dyeing pattern that preserves a natural impression. Based on the simulation of the proposed dyeing process, we developed a system that generates patterns based on KANSEI. Associating KANSEI with pattern generation parameters produces dyeing patterns that exhibit the required impressions (KANSEI) for the generated dyeing patterns. Based on this development method, we constructed a basic system for pattern generation and verified the effectiveness of the method.

The Impact

Building skins are persistently exposed to changes in the weather, including the cases of weather extremes, increasing in frequency due to global climate change. As a consequence of the advancements of digital design tools, the integration of the weather conditions into the design process is much smoother. The impact of the ambient conditions on buildings and their structures can be digitally analyzed as early as in the conceptual design stage. These new design tools stimulate original ideas for shape-changing building skins, actively reacting to the dynamic weather conditions. In the paper, a digital design method is introduced, leading towards the design of a building skin, able of the passive shape adaptation when subjected to the wind. The designed building skin consists of a tensegrity structure where the tensioned elements are substituted by a tensile membrane, creating a self-equilibrated building skin element. In the previous research, a small prototype of this wind-adaptive element was created. The computer simulations are employed to predict the adaptive behavior of a bigger, full-scale building skin element. The before-mentioned building envelope becomes an active player in its surrounding environment, passively reacting to the wind in real-time, thanks to the geometric and material properties. Due to the local shape changes caused by the wind force, the wind can be perceived unconventionally through the adaptive building structure.

This paper presents a garment pattern generation process and modelling of virtual garment design method in 3D. This work characterize our global project on virtual clothing design contains of the conception of virtual adaptive mannequin, and also of the creation and modelling of garment in 3D. According to the ideas of mass customization and e-commerce, as well the need of numerical innovations in garment industry we employ our model of virtual garment and methodology enabling to conceive the virtual clothing directly on a mannequin morphotype in 3D. This method gives us possibility to create a perfect garment and taking into account all peculiarities of human body. In 2D method we made two patterns: left and right side separately to obtain best result and to get possibility to compare two cases: when symmetric pattern is used and when we use pattern consisted of two parts specially made for each side of the body. In the present context we use the example of a basic women's shirt: bodice and sleeve. We used the method of making pattern employed in Russia compared with French method. Finally the superposition of virtual and real pattern was done in order to visualise the right results.

It is an innovative design method in physics that product layout design is abstracted into convex hull plus rubber band simulation layout mode by setting up the optimized model. Based on the physics model of Newtons Second Law, this paper analyzed collision detection methods during the process of realizing reasonable layout, and it is founded that real-time collision detection and collision response during movement, produced components within the given beat, appeared to be the key content of resolving digital model design. In this paper, Area Difference method was adopted to detect when the collision occurred during component movement and what kind of state the component tended to be in collision. At the same time, it also determined the interference degree, solved critical point pose for collision response as well as its generation time and related torque and force, which can confirm the components continued movement model of rotation and sliding. Meanwhile, it employed the Judgment Matrix method to analyze collision response so as to confirm the collision interference relationship and collision action state, movement possessing mode (rotation, sliding and retraction, etc.) within the remaining time after collision with given beat during the layout process. All these provided with a practical solution for digital design of optimized model based on convex hull plus rubber band simulation compact layout.

To establish a new three-dimensional (3D) digital design method for osteotomy and assess its application value in the surgical treatment of hemivertebrae. Preoperative 3D digital designs for osteotomy of the hemivertebrae were performed, which included computer simulation of the osteotomy and the internal fixation process, and computer-assisted design (CAD) of the templates for osteotomy of the hemivertebrae, pedicle screw positioning, and internal fixation rods. Template-guided osteotomy of the hemivertebrae plus pedicle screw and rod internal fixation were accurately implemented. The preoperative use of this new computer-aided 3D digitized and paperless surgical design can improve the safety, accuracy, and operative time for osteotomy in the treatment of hemivertebrae.

Traditional digital camouflage is mainly designed for a single background and state. Its camouflage performance is appealing in the specified time and place, but with the change of place, season, and time, its camouflage performance is greatly weakened. Therefore, camouflage technology, which can change with the environment in real-time, is the inevitable development direction of the military camouflage field in the future. In this paper, a fast-self-adaptive digital camouflage design method based on deep learning is proposed for the new generation of adaptive optical camouflage. Firstly, we trained a YOLOv3 model that could identify four typical military targets with mean average precision (mAP) of 91.55%. Secondly, a pre-trained deepfillv1 model was used to design the preliminary camouflage texture. Finally, the preliminary camouflage texture was standardized by the k-means algorithm. The experimental results show that the camouflage pattern designed by our proposed method is consistent with the background in texture and semantics, and has excellent camouflage performance in optical camouflage. Meanwhile, the whole pattern generation process takes a short time, less than 0.4 s, which meets the camouflage design requirements of the near-real-time camouflage in the future.
