Three-dimensional representation of a 150 nm-thick thin titanium film surface. A section of an original scanning electron micrograph, 512 × 512 pixels in size was selected for conversion into a 3D object (a). The image was assigned to a 2D polygonal plane as a displacement map, and a terrain color map was applied (b) before depth translation according to the pixel height values. Note that the color map presented in (b) has been calibrated through the use of AFM roughness data.
