In the last submission, we showed SdibiT’s VHuman creation method. Watching the video, we can know that SdibiT creates 3D Digital Torsos in advance based on the target consumer groups’ body shape big data analysis and processing. And the shapes and values of each cross-section of these 3D Digital Torsos are standard data formed by precise calculation. So that the 3D digital torsos we make are in optimized body shape and this is the basis for making clothes that fit customers and can make their figures look better.
Today let’s go on our next session. How the garment pattern is generated?
How to convert the clothing design into industrial production patterns accurately and efficiently is the most difficult problem in the apparel industry. We believe that the 3D Digital Torso database building and its flexible application based on dynamic algorithm is the fundamental source of the digitization of apparel industry. Without the building of 3D Digital Torso database, any digital transformation solution cannot solve the key issue.
Therefore, our VHuman creation, virtual clothing design, conversion of 3D digital design to actual pattern for production, and final virtual display on VHuman, all these steps are performed on the unified 3D Digital Torso. This means we use the same 3D Digital Torso data throughout the entire digital solution process.
Here, we will explain our 3D design and pattern-making digital solution in comparison with the physical draping in traditional design studios. And we start from the basic point of prototyping.
In the process of physical draping, as human eyes are not X-ray machines, it is impossible to see the actual space between the fabric and physical mannequin from all perspectives. So it is very difficult to achieve the ideal looseness for each part in real time. In addition, human eyes are not omnidirectional camera. There is no way to view the real time condition from the front, side, back or top perspective at the same time. So if an adjustment is made at one part, it is very difficult to see the effect on the overall clothing. However, our digital technology can visualize the distance between fabric and torso, the aesthetic sense and even the proportion balance in the hollow state at the same time.
Now, after establishing the 3D Digital Torso as the basis, we enter the most decisive digital processing phase. We set the looseness value between the garment and the 3D digital torso according to the actual wearing looseness requirements of different types of clothes. Then 3D Digital Garment Models for different types of clothes can be generated after sophisticated simulation. All of our designs are made on these 3D digital Garment Models. This is the reason why even design varies depending on different cutting lines, the actual looseness commonly known as comfort of wearing on consumers can achieve a stable level.
As in the video posted last time, taking women’s blouse in East China as an example, you can see the 3D Digital Garment Model we provided for customers in the hollow state.
Next, on the digital blouse prototype model, directly restore the blouse design artwork, and then directly add the cutting line. In the process of 3D modeling, more excellent curves are recommended through precise simulation. After confirming that the specified design is faithfully reproduced on the 3D Digital Garment Model, 2D patterns can be converted from 3D by flattening in real time. And the 2D pattern of actual size for clothing production is now generated.
You can also see in the video attached below that intersection points we marked on the digital garment model can correspond to the same point no matter how many different patterns are generated later. In other words, 3D Digital Garment Model is like human DNA to our solution.
It can be confirmed as DNA that the points are in the same position even if the shape of the pattern is different.
This is why we emphasize that the output of the 2D production pattern must be under the 3D digital verification. Because the current 2D #CAD software products cannot achieve such precise control.
