Polatory is a fast and memory-efficient framework for RBF (radial basis function) interpolation.
- Interpolation of 1D/2D/3D scattered data
- Surface reconstruction from 2.5D/3D point clouds
- Fast kriging prediction (dual kriging)
- Quality isosurface generation
- Supports over 1M of input points
- Inequality constraints
- Gradient constraints (Hermite–Birkhoff interpolation)
