TinySpline is a versatile library designed for working with spline curves, specifically Non-Uniform Rational B-Splines (NURBS), B-Splines, and Bézier curves. It is primarily implemented in ANSI C, ensuring portability and efficiency, with a C++ wrapper providing an object-oriented interface. The library's core purpose is to provide a compact yet powerful set of tools for interpolation, transformation, and querying of these curves, with extensive bindings available for numerous programming languages.
TinySpline stands out due to its small footprint and comprehensive support for various spline types and operations. Its cross-language bindings enable developers to leverage the library's functionality in their preferred programming environment without significant overhead. The library's focus on a clean and efficient C implementation contributes to its performance and reliability, making it suitable for a wide range of applications.
- Cross-Language Bindings: Provides interfaces for C++, C#, D, Go, Java, Javascript, Lua, Octave, PHP, Python, R, and Ruby.
- Comprehensive Curve Types: Supports NURBS, B-Splines, and Bézier curves with flexible control over degree and dimensionality.
