robust-in-sphere

robust-in-sphere is a JavaScript library providing an exact arithmetic test to determine if a collection of `n+2` points in `n`-dimensional space are cospherical, or if the last point is contained within the sphere defined by the preceding `n+1` points. This library focuses on robust predicates to avoid floating-point errors, a common issue in computational geometry, drawing inspiration from Jonathan Shewchuk's seminal work. Currently at version 1.2.1, it was last published in 2014, suggesting a stable but not actively developed state. Its primary differentiator is the use of exact arithmetic for geometric predicates, ensuring reliability over speed for critical calculations. While not as fast as some alternatives, its exactness is crucial for applications requiring high precision in geometric computations.
