Module flatten_simd

This is a temporary module that contains a SIMD version of flattening of cubic curves, as well as some code that was copied from kurbo, which is needed to reimplement the full flatten method.

Structs

FlattenCtx

The context needed for flattening curves.

Point32 🔒

Constants

MAX_QUADS 🔒

This limit was chosen based on the pre-existing GitHub gist. This limit should not be hit in normal operation, but might be hit for very large transforms.

Functions

An approximation to $\int (1 + 4x^2) ^ -0.25 dx$
