description="
A C++ and Python library of 2D and 3D vector, matrix for computer graphics.

Imath is a basic, light-weight, and efficient C++ representation of 2D and
3D vectors and matrices and other simple but useful mathematical objects,
functions, and data types common in computer graphics applications,
including the half 16-bit floating-point type.

Imath also includes optional Python bindings for all types and functions,
including optimized implementations of vector and matrix arrays.
