Shoe Scan

[Roxanna Bornemann]

Wellthe raw scan is what it looked like in the first couple of images, I did retopology and some good UV plates, which you can see in the second batch, what your seeing in the final renders is the very fine details, those were a result of a sony alpha DSLR photo. I took up close images of the shoe knits, from those photos I pulled height data then textured the shoe using those. to be clear the scan data was only used as a base for me to retopo the shoe, for speed and accuracy, while maintaining a fully VFX friendly model.

Check out these screengrabs, I hope that sheds some light on the process.

This is a screengrab of photoshop and cinema, but you can see the photo I pulled the height data from alongside of the render output up close to the knit.

This is a screengrab of the material network, the color roughness etc are derived from my single knit Displacement tiled accross the vamp of the shoe.

Nearly 80 percent of us have a noticeable discrepancy between our left foot and our right foot. Our trained Outfitters are dedicated to understanding what makes your feet unique by using best-in-class technology and personal expertise to put you in the best shoes.

Whether you want to walk farther, tackle your first race, or chase down a PR, our specialized fit process combines the best in customer service with insightful technology to deliver unbeatable comfort mile after mile.

Depending on how your body naturally moves while you walk or run, our Outfitters can determine the amount of support you need from your shoes. The type of foam, arch support and upper construction can all affect how comfortable you feel on the move in your shoes.

Our state-of-the-art scanner uses a set of specialized cameras to capture 12 precise data points to construct a 3D image of your foot. Measurements like foot length, width, volume and arch height help us fit you in the best shoes for your unique feet.

Fleet Feet outfitters create a profile for you based on your 3D scan so you can save your data and revisit it later as you shop for shoes either in store or online. We can even order custom insoles so you can take your unique support system with you when you buy new shoes.

Our Outfitters use a specialized pressure plate* to analyze your gait pattern and the pressure points on your feet as you walk. This helps us get a clear idea of the way your body moves and the support and cushioning you may need based on the natural rolling motion of your feet.

Understanding where your body places pressure on your feet while you walk lets us gauge if you have a neutral gait or if you pronate or supinate. While there is no correct way for your body to move, you can make sure you feel (and look) your best while you run or walk by getting shoes that are designed to support your foot at high-pressure points.

We used a modified version of our ultra high resolution head scanner to scan the brand new Nike Inneva Woven shoe. The talented guys at Devilishly handsome Productions took our cleaned up textured model and created the fantastic promo new playing in the window above.

PNNL recently licensed the two technologies to Liberty Defense Holdings, Ltd., a concealed weapons detection company. Licensing government-developed technologies to the private sector is one of the missions of national laboratories like PNNL.

A shoe scan involves the traveler pausing on a low-profile imaging platform for about two seconds. Electromagnetic waves are used to generate an image of the shoe, which is evaluated to determine if an object may constitute a threat.

Based on the national need researchers saw for a shoe scanner, PNNL began development using internal R&D funds. DHS funded additional development of the technology through the Science and Technology Directorate's Screening at Speed program, while also supporting development of a new generation of millimeter wave body scanners that can provide higher resolution images at much lower cost. The original scanner design, previously developed by PNNL, has been widely used for about 15 years as a valuable screening tool at Transportation Security Agency airport checkpoints in the U.S. and abroad.

The new system design includes improved antennas and significantly reduces imaging irregularities. With this advancement, airline passengers or people attending large public events may be scanned while wearing light sweaters or jackets, instead of having to take them off before walking through the scanner portal.

The HD Advanced Imaging Technology system will be able to incorporate the latest threat detection algorithms that may be developed by third parties. Its open architecture will provide operators the flexibility to select and use best-in-class threat detection algorithms instead of being limited to one specific type.

Liberty Defense envisions building upon and enhancing the capabilities already achieved on the HD-AIT, with the intent to commercialize and manufacture the platform," said Frain. "The goal is to seamlessly upgrade current systems at airports while preserving the existing footprint." Frain added that the shoe scanner may be integrated into the base of the next generation HD-AIT. We see options in various venues for separate scanners or a combined version," he said.

The F-Scan In-Shoe system is a compact, new generation technology for clinicians and researchers that provides dynamic pressure, force and timing information for foot function and gait analysis. Information obtained from the F-Scan is used in real-world applications, like designing and testing orthotics, offloading diabetic feet and evaluating footwear and techniques in elite athletes.

The lightweight, cord-free, wearable electronics with onboard storage lets your subject enjoy full freedom of movement while you capture their natural in-shoe gait with the highest resolution data in the market.

F-Scan GO sensors have optimal spatial resolution for in-shoe pressure measurements, and the highest resolution sensing on the market. The sensors are ultra-thin, yet durable enough to last for multiple trials.

"One power of the F-Scan system lies in the immediate and totally obvious visual feedback. Most cases are definitive even without referring to the staggering ability of the software to represent the data in any way you can think of. This simplicity combined with the fact that it is a foolproof means of pre- and post-testing treatment methodology makes this system invaluable to the clinician."

You can watch real time pressure data captured in the software over WiFi while configuring. The FootVIEW software communicates with the devices to capture real-time data, calibrate the sensors and control recording. When you start recording, data is collected directly to Micro SD cards in the TekDAQ units at a sampling speed of up to 500 Hz. At the completion of each recording, the recording data is automatically transferred back to the PC over WiFi to provide immediate access for analysis. This allows F-Scan GO to have the fastest possible sampling speed, even when connected over WiFi.

"We want to build a system that creates product when you need using the only the materials you need when you need it, as opposed to an industrial system that's making huge mountains of stock with subtractive processes."

The trainers build on Vivobarefoot's VivoBiome shoes, which are also 3D-printed based on scans of user's feet, but are made from more traditional materials. Currently 176 "paying pioneers" are testing the first generation of the red VivoBiome shoes.

Although the product is biodegradable and compostable, it was not designed to be composted in a back garden. Vivobarefoot expects the product to be composted in an industrial facility, and establishing this process will be one of the tasks that need to be set up before a mass launch.

"In a compost environment you have specific enzymes that know to digest the monomers and it's the same enzymes you have in industrial and the same one you will have in your home compost," he continued.

"So legally, we can say yes, put it in your home compost, and it will biodegrade. But the truth is that we don't know how long it will take and we don't know if you have a compost in your garden," he continued.

The trainers form part of Vivobarefoot's wider aim to radically change the footwear business as it believes that heavily cushioned shoes are damaging people's feet. It aims to create shoes using as little material as possible.

"Shoes aren't just trashing your health, all that fancy underfoot, cushioning and support that you're used to under your feet is actually making them shoe shaped and weak, which negatively impacts the way you move and ultimately negatively impacts your health."

Clark believes that the majority of "shoes are trashing your feet and the planet". Along with reducing the amount of material that goes into shoes and considering what happens at the end of their life, he believes that the whole manufacturing process needs to radically change.

"It's also complicated, there's multiple layers to the supply chain and it's almost impossible to get your hands around in terms of the true environmental impact. But it's ultimately wasteful by design."

All scans are done at 300* or 600** dpi at the original print size and saved as JPEG files. Photos must be loose and unmounted, not in photo albums, not torn or bent, no glue, staples, or post-it notes, and not smaller than wallet sizeof 2 by 3 inches or larger than 5"x 7". Photos should be put in order by size and set in an upward direction as we do not rotate any images. Although we can not guarantee it, we will make every effort to insure that all images are scanned in order and correctly oriented.
