3D Printed Stencils for Texturing Flat Surfaces
  We address the problem of texturing flat surfaces by spray-painting through 3D printed stencils. We propose a system that (1) decomposes an image into alpha-blended layers; (2) computes a stippling given a transparency channel; (3) generates a 3D printed stencil given a stippling and (4) simulates the effects of spray-painting through the stencil.
