TNB frame
Description
A
frame is a local coordinate system that may change along a space curve.
The t, n, and b vectors are mutually orthogonal, kind of like the x, y, and z axes. However, unlike the xyz axes, the tnb frame changes along the space curve. The n and b vectors specify the plane orthogonal to t.
A TNB frame is also known as a Frenet frame.
When t, n, b are normalised and mutually orthogonal, they are said to form an orthonormal basis spanning 3D space.
