# ARCS - scratch hologram gcode generator This tool acts as a slicer and generates gcode for scratch holograms. ## Input The input is a r8g8b8a8 image: - rgb - "color" values (can be grayscale) - alpha - normalized height for the parallax effect The rgb will be interpreted as grayscale values and dithered. The alpha will be reinterpreted: - 0.0: fully inside the material - 1.0: fully outside the material ## Output gcode, which can be piped to a 3d printer.
