Geometric Regression Library (GeoRegression) is a free Java based geometry library for scientific computing in fields such as robotics and computer vision with a focus on 2D/3D space. The goal of GeoRegression is to provide all the core functions for estimating the closest point/distance between geometric primitives, estimating best-fit shapes, and estimating and applying geometric transforms. It is designed for high performance and ease of use. GeoRegression has been release under an Apache v2.0 license for both commercial and non-commercial use.


  • Geometric primitives
    • Points, lines, vectors, ... etc
  • Dimensionality
    • Full support for 2-D/3-D space.
    • Minimal support for N-D space.
  • Metric measures
    • Distance, closest point, and points of intersection.
  • Transforms
    • Rigid body 2D/3D, homography, and affine.
  • Best Fit
    • Shapes (e.g. best fit line from points).
    • Motion/Transform (e.g. motion for a set of point pairs).
  • Support for both 32-bit and 64-bit floating point numbers.
    • Types: float and double.
    • Limited support for integers types.
