i_overlay

The i_overlay is a poly-bool library that supports main operations such as union, intersection, difference, xor, and self-intersection by the even-odd rule. This algorithm is based on Vatti clipping ideas but is an original implementation.

Features

• Supports all basic set operations such as union, intersection, difference, exclusion and self-intersection.
• Capable of handling various types of polygons, including self-intersecting polygons, multiple paths and polygons with holes.
• Optimizes by removing unnecessary vertices and merging parallel edges.
• Effectively handles an arbitrary number of overlaps, resolving them using the even-odd rule.
• Employs integer arithmetic for computations.

Working Range and Precision

The i_overlay library operates within the following ranges and precision levels:

Extended Range: From -1,000,000 to 1,000,000 with a precision of 0.001. Recommended Range: From -100,000 to 100,000 with a precision of 0.01 for more accurate results. Utilizing the library within the recommended range ensures optimal accuracy in computations and is advised for most use cases.
