# GLKVector2Lerp(_:_:_:)

Returns a new vector created by linearly interpreting between two vectors.

## Declaration

```swift
func GLKVector2Lerp(_ vectorStart: GLKVector2, _ vectorEnd: GLKVector2, _ t: Float) -> GLKVector2
```

## Parameters

- `vectorStart`: The starting vector.
- `vectorEnd`: The ending vector.
- `t`: An interpolation constant.

## Return Value

Return Value A new vector.

## Discussion

Discussion The value of t should typically be between 0.0 and 1.0. A value of 0.0 returns the starting vector and a value of 1.0 returns the ending vector. Any other value of t results in a linear interpolation between the two points.
