Auryn Ink simulates watercolor on the iPad

Benjamin Rabe

Fun new app (iTunes) that computes a watercolor particle system while you paint.

Auryn Ink’s Key features (from the press release):

  • Watercolor simulation with edge darkening, granulation and back-run effects that all evolve and take form in real-time while you paint.
  • Choice of canvas texture that affects your brush strokes and paint flow.
  • Realistic brush model with control over pressure, bristle patterns, and more.
  • Unique color selector that converts your color choice into a virtual pigment.
  • Pigment simulation that blends color much like real watercolors combine: the wet pigments mix together and separate dry layers form glaze effects.
  • Control over amount of water on the brush, which influences flow effects.
  • Ability to paint with water alone to pre-wet the canvas for wash effects.
  • Concise control over drying the canvas, and completing (fixing) glaze layers.
  • Sensitivity to gravity: paint flows downward when the iPad is tilted.

The payoff for computing watercolor behavior seems to be resolution for now, but nice results nonetheless. The app is free for now.
