Abstract
Techniques which enable changing certain amount of energy being applied from a laser to a material during scan lines of the laser. Energy can be applied to a material to change its look. Different energies can be applied within a single scan line to the material. A display can represent the pattern, by showing different areas of change to the material as different colors/looks on the display. For example, the color of the display can represent the amount of energy being applied to a specific position represented by that color. Since the amount of energy that is applied can change within a single scan line, and in fact may change multiple times within that scan line, this enables freely setting the characteristics.
