pose
Calculates the pose Matrix44 (i.e. translation and rotation) that describes an orthonormal basis formed by normal and tangent of the contour at t.
Which means it returns a Matrix44, that you can use to orient an object the same way the curve is oriented at given value of t.
Parameters
t
The value of t in the range of 0.0
to 1.0
at which to return the pose at.
