A footwear marketing project for Nike What's important when 3D scanning products such as fashion footwear? We 3D scan objects across all sectors. When we are working in fashion we know capturing all the colours, textures and natural idiosyncracies of the product is so important. The 3D scanner captures colour data brilliantly and this is part of the story, however often for projects requiring increased detail and information we have to go a stage further - into macro photography. Macro photo's (see images) give us the ability to understand the knap, texture and make-up of fabrics and materials in almost microscopic detail. By seeing how they are constructed and fabricated we can create textures in greater detail than any 3D scanner can capture. This helps us deliver for our clients at a superior level.
Creating decent topology for each polygroup is the foundation of good texturing. Again we look at parts of the shoe that will be shown more, or have more time under scrutiny of the camera (for example the top / front instead of the sole / rear). In this example for Nike the entire shoe needed a fairly comprehensive level of detail all over. Including the interior and insole. The interior and insole needed an added amount of rebuilding in the design software as the 3D scanner cannot capture deep inside holes. Our design capabilities are put to work in this instance and we combine with the macro photography to ensure the detail carries through. As we finalise the stitching and textures we cleanup the colours and materials ready to export to maps. The final 3D model of the Nike footwear is complete, with mesh and maps ready to export and send to our client's animation dept.
With all 3D scanning projects, there are a thousand ways to skin a cat. Technology and processes change all the time and we find it is our desire to deliver above and beyond what our client needs that distinguishes a successful project from a failure. Thus we put technology to one side and simply focus on delivering in an awesome way every time!

Vin Burnham (in association with Alli Eynon) forged a new path for super-hero costume with the sculpting of the original 1989 Batman costume (under supervision of Costume Designer Bob Ringwood). At the time I was eighteen and knew the significance of the suit even then. I knew history was being made, and it is testimony to Tim Burton's desire to create such a visual spectacle, and Vin's ability to bring something so special into being that changed the movie world forever. Not just the technical aspects of the suit's creation but from a wider perspective it became uber-cool for actors to take on super hero roles. Both busts ready for 3D scanning The amazing Jose Fernadez of Ironead Studios is using the 3D scans to create replica suits, and 3D scanning is the perfect way to accurately bring all the detail and idiosyncracies of the original sculptures into the digital realm to subsequently work from. The two sculptures were originally created as 'concept' and 'final' busts, to give Tim Burton something tangible to sign off, so the costume could go into full production. Both busts are cast plaster from a waste-mould, made in production 30 years back. A waste-mould is a mould used for one cast only, so these casts are one-offs, made from Vin's clay sculptures (the clay versions destroyed as part of the moulding process). The bottom line is, if something happens to these sculptures, without 3D scans there is no accurate 3 dimensional archive by which to refer or even 3D print copies. From a practical standpoint, plaster is a great material for 3D scanning as there is no reflection or light bouncing off the surface which can affect the 3D scanning process. 3D scanning the sculptures The Creaform Go!Scan 20 I used is a portable white light scanner, capturing highly detailed scans with high point accuracy. I needed to put some targets (little dots) on for the scanner to lock onto the surface and ease the scanning. It scanned really well, capturing even the little imperfections such as the broken tips of the ears. Post-processing the scan was relatively simple, filling some holes, repairing the ear tips and any little dinks and dents from 30 years of life (we all have a few of them!). The final files looked great - watertight mesh ready for further digital transformations... Now the sculptures are immortalised digitally ready for another 30 years of storage! The sculptor in me wants to take inspiration from the files and create a retro, concept cowl for fun, as a homage to what was a fantastic turning point in movie history.

Join Greg Lawrence as he describes the process and pain of creating a lifesize sculpture of the world's cutest mammal! Stage1 - Research I wanted to design the cub with a keen yet vulnerable look, so I set to researching Polar bears and cubs. I immersed myself in the look and feel of the little mammals, watching them walk, run, roll around, sniff the air...it all helped gain a really good feel for how I may bring some of the expression out in the sculpture. Stage2 - Digital sculpture Creating sculptures digitally in my view is the most efficient, expressive way. It gives me a chance to try multiple poses, shapes and anatomical variations in a way that is simply not practical with real clay or modelling materials. I have a mad passion for digital sculpture and founded the Freelance 3D Modeling group on Linked In as a result of my passion and to join virtual hands with sculptors the world over. You can see below the cub went through various stages from early blockout through refinement and finally I found the form I was looking for. It was a really painful process, trying to create a kind of light, fluffy look to something which will effectively be a solid. I gave the digital sculpture a little paint so I could be sure I would be able to find the right look with the real finished model. Stage 3 - 3D Printing the Cub Taking the digital file and creating a 3D print is the simpler part of the process for an object that is only 600mm tall. The body was created using SuperHuge 3D printing, which is made for objects 1m up to unlimited size, so this was on the smaller side of things. The face was 3D printed in ABS and fixed to the polystyrene before cleanup ready for moulding. Stage 4 - Moulding & Casting a Polar Bear Army I created a silicone jacket mould - a soft rubbery jacket with a hard casing - so the cubs could be spray-cast in resin. This is a really cost-effective way of quickly making a short run of casts. Each cast came out, and was cleaned up and primed white ready for painting. Stage 5 - Painting: Bringing the Cubs to Life This was a fantastic challenge. We all have preconceptions that Polar bears are white - yet in fact there is a marvellous depth of colour to their fur. Additionally the colour is affected by two other factors: light and dirt. The quality of light and time of day affect the colour of the fur dramatically as each strand of fur holds and absorbs the light rays. For example at sunset the fur takes on a glowing, deep, creamy colour. Yet in a blizzard the fur is a flatter, whiter colour. Our cubs would be in shops on the harbour front in Plymouth, so also had to look natural in their retail environment. Dirt was the second factor, and often the fur is grubby around the feet and belly area. Reds and browns, clay-like from the natural habitat (when not on snow and ice) give a realistic quality. I took all these factors on board and decided to go for a clean, warmish design. Not too grubby. When it came to painting the face, I worked really hard to paint and airbrush an inquisitive, alert look. I spent hours looking at Polar bear eyes, desperate to understand how and why they looked vulnerable in one image, yet happy in another. Finally I reached a look I was happy with. ...and Finally The Final Sculptures Launched at the National Marine Aquarium Airbrushed to look consistent across each cub. I was pleased to have achieved a soft, fluffy look with a vulnerable yet inquisitive feel. #polarbearexplorers #sculpture #3dprinting #3dmodelling Watch the YouTube Timelapse Video Timelapse showing the painting and airbrushing of the little army...

On the surface of things it seems easy, but the reality is a little more complex and knowing when to use 3D scanning is a skill in itself. The purpose of this article is to help you understand when it is good to make that call. There are plenty of articles on how 3D scanners work and the different types of 3D scanners, and I really just wanted to tackle why and when you should choose 3D scanning over traditional CAD creation. Ultimately the driving force behind a decision to choose 3D scanning is either because it's cheaper than the alternative, it's quicker or it simply cannot be matched by quality. The sweet spot for a customer is all three reasons. Let's get started: 1. The object has complex, compound, curved surfaces
2. If accuracy is important to you
3. You want an exact mirror of an original part
4. You need to archive an original object (art or heritage)
5. You want to capture the texture (colour information)
6. There is simply too much detail
6. You can't touch or work on the original object
Quick Summary 1. Does the object have complex, compound curves? If yes you should seriously consider 3D scanning 2. How important is accuracy? If it is important to you, 3D scanning is the right choice. 3. Do you want to mirror an existing part? If so 3D scanning is the way to go. 4. Do you need to archive an original object or artifact? If yes there is only one answer: 3D scanning. 5. Is capturing the colour information important to you? It is impossible to recreate any kind of complex colour information as quickly and economically as 3D scanning. 6. Is the object extremely detailed? If so it will be much quicker to 3D scan than recreate from scratch in computer software. 7. Is the object too fragile or valuable to risk getting damaged by a moulding process? If so 3D scanning is non-invasive and non-destructive and the only way to go.
