# pose

fun pose(t: Double, polarity: YPolarity = YPolarity.CW_NEGATIVE_Y): Matrix44

Content copied to clipboard

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.
