Perform a spherical linear interpolation from v0 to v1 according to f. The value of f should be in the range [0..1] otherwise the results are undefined.

Slerp is normally used to interpolate quaternions, but there is a geometric formula for interpolating vectors directly, see "Geometric Slerp" in: https://en.wikipedia.org/wiki/Slerp.

This interpolates the vectors' directions via slerp, but linearly interpolates the vectors' magnitudes.

Results are undefined if v0 or v1 are of zero magnitude.

Parameters

`v0`	`Float64Array`
	The first vector.
`v1`	`Float64Array`
	The second vector.
`f`	`number`
	The interpolation factor.
`resultVec`	`Float64Array`
	The vector to receive the results (may be v0 or v1).

Returns

Float64Array

Return resultVec so that operations can be chained together.

VIEW SOURCE

Parameters

`vec0`	`Float64Array`
	The minuend.
`vec1`	`Float64Array`
	The subtrahend.
`resultVec`	`Float64Array`
	The vector to receive the result. May be vec0 or vec1.
