  abstract = {We present a physically inspired model of wax crayons, which
              synthesizes drawings from collections of user-specified strokes.
              Paper is represented by a height-field texture, and a crayon is
              modeled with a 2D mask that evolves as it interacts with the
              paper. The amount of wax deposition is computed based on the
              crayon contact profile, contact force and friction. Previously
              deposited wax is smeared by crayon action, based on wax softness
              and contact information. Deposited wax can also be carved from the
              paper by the crayon and redeposited at another location. The
              distributed wax is rendered using a simplified Kubelka-Monk model,
              which approximates light transmission and scattering effects.},
