Crayon: 3D Sketching

About the app.

Crayon is a spatial sketching and modeling tool that works with hand gestures or Logitech Muse. Lines, shapes, and sculpted forms can be created directly in three dimensions, making it possible to develop an idea at the scale where it might eventually exist.

Brushes, colors, and shapes can be customized, while images and USDZ models can be imported as references or parts of a larger composition. FaceTime and SharePlay let distant collaborators paint inside the same project instead of exchanging static screenshots.

The controls are approachable enough for experimentation but flexible enough for artists and designers to build more deliberate work. Crayon suits people who want spatial creation to begin with drawing rather than a dense desktop modeling interface.
