NDArray
NDimensional array data structure like numpy's ndarray.
 Efficient storage in Typed Arrays
 Flexible slicing and indexing
API Reference
Linear Algebra
Vector and Matrix Math.

Powered by venerable LAPACK library, compiled to Javascript using Emscripten.

Solving of linear equation systems (LU decomposition, Least Square)

Matrix decomposition operations (SVD, Cholesky, QR)

Standard matrix properties (Rank, Determinant, Inverse)
NURBS geometry
Implementation of NURBS curves and surfaces (NonUniform Rational BSplines), which work as building blocks of Geometry primitives in a CAD applications

Bezier Curves and Surfaces

Rational BSpline Curves and Surfaces, with algorithms for degree elevation, knot refinement etc.

Adaptive tessellation
Topology
Implementation of topology using Winged edge data structure. Used in addition to geometry to do Solid modeling in CAD applications

Topology classes that define Vertex, Edge, Face, Loop, Body

Manipulation of topology by means of Euler operators
