Design|Craft Vol. 1, Upholstery Leather
Have you ever wondered why there seem to be no good leather textures available on the market? Arroway did. And now they know why.
Leather is one of these materials the appearance of which is defined in large part by their surface structure, not just surface color. So Arroway knew from the outset that our conventional approach wouldn’t do.
Instead we developed an entirely new photo-optical scanning process, consisting of custom hardware and software that allows us to capture a multiplicity of surface characteristics of nearly any kind of physical material. Most importantly, it can capture 3D surface and roughness information at pixel resolution. Other properties such as opacity, translucency and anisotropy can also be captured, which we will use for later products.
With this new scanning process we are able to digitize materials with an arbitrary surface area at (almost) arbitrary resolutions.
Thousands of images have to be processed for each texture
So how does it work?
Arroway start with a series of photographs of the surface in different and very carefully controlled lighting conditions. All these images are then fed into a custom piece of software that basically tries to answer the following question: If the surface looks like this in this image and like that in that image, what would the surface’s 3D structure necessarily need to look like?
Doing this for each pixel in a large number of individual image pairs makes it possible to create a precise reconstruction of the original surface. Other surface properties are extracted in similar ways, e.g. using polarized light or high-dynamic range image data.
Different map types captured with our scanning process
There is of course a lot more to it and a number of unforeseen difficulties – most of which on the hardware side – had to be overcome to make it all work. The final process ended up being rather involved and taking lots of time and processing power. But Arroway think the results are worth the effort and speak for themselves.
