B├ęzier Curves
You can start by drawing a freehand stroke and end up in a precise technical drawing with with the help of Bézier curves. You can modify them by adding or removing control points, even modifying the properties provided by Apple Pencil like Force and Speed to change their thickness and opacity.

Converting Bézier Curves to polygons is important in Atai. From curves solid polygons are created, which together with the Layer masks, can form halftone effects very easily. You have at your disposal a variety of Textures.

Freehand drawing
Accuracy and dynamism, Atai plays between the two worlds. You can concentrate at the beginning on the dynamism of your paths and step by step you can reach the final accuracy. Bézier curves play an important factor in this process.

Color Palettes
Atai allows the creation of Color Palettes and their easy use in each drawing. As a base we try to create palettes based on COPIC colors as well as possible.
Over time we will add others.
COPIC is a Registered Trademark of Too Corporation.
