Returns the spherical linear interpolation of points between two vectors
Arguments
- x, y
numeric. Can be three element vector, three column array, or an
object of class "line" or "plane"
- t
numeric. interpolation factor (t = [0, 1]).
Details
A Slerp path is the spherical geometry equivalent of a path along a line
segment in the plane; a great circle is a spherical geodesic.
Note
For non-unit vectors the interpolation is not uniform.
