Curve:getTangent

Returns a direction vector for the Curve given a parameter t from 0 to 1. 0 will return the direction at the first control point, 1 will return the direction at the last point, .5 will return the direction at the "middle" of the Curve, etc.

x, y, z = Curve:getTangent(t)

Arguments

NameTypeDescription
tnumberWhere on the Curve to compute the direction.

Returns

NameTypeDescription
xnumberThe x position of the point.
ynumberThe y position of the point.
znumberThe z position of the point.

Notes

The direction vector returned by this function will have a length of one.
