Module lyon_tessellation::basic_shapes

Tessellation routines for simple shapes.

#Overview

This module contains tessellators for specific shapes that can benefit from having a specialized algorithm rather than using the generic algorithm (for performance purposes or in some cases just for convenience).

See also the generic fill and stroke tessellators.

Some of these algorithms approximate the geometry based on a tolerance threshold which sets the maximum allowed distance between the theoretical curve and its approximation.

This tolerance threshold is configured in the FillOptions and StrokeOptions parameters.

More explanation about flattening and tolerance in the lyon_geom crate.
