Drawing in 3D

Engineers use two LCD monitors and some computers to create 3D drawings of a KolourOptik image and simulate them to see how it might look. The drawings and computer simulations are created with NTS’s proprietary simulation software and can create unlimited color and pattern choices because the technology uses billions of nanoholes that each trap a single wavelength of light.
