Which approach would you choose for implementing morphing and why?

To implement morphing (smooth transition between two images or shapes) in Go, I would choose an approach using intermediate frames, where each image is broken down into key points (control points), and then intermediate states are calculated between them. This can be implemented through linear interpolation of point coordinates and colors.

Why exactly this:

• Go does not have built-in libraries for morphing, so the algorithm needs to be implemented manually.
• This approach is versatile and allows control over the quality of the transition.
• Data structures can be used to store points and functions for interpolation.

An example of a simplified algorithm:

// Point represents a coordinate
type Point struct {
    X, Y float64
}

// Interpolate linearly interpolates between two points
func Interpolate(p1, p2 Point, t float64) Point {
    return Point{
        X: p1.X + (p2.X-p1.X)*t,
        Y: p1.Y + (p2.Y-p1.Y)*t,
    }
}

// Morph takes two sets of points and a parameter t from 0 to 1
func Morph(points1, points2 []Point, t float64) []Point {
    result := make([]Point, len(points1))
    for i := range points1 {
        result[i] = Interpolate(points1[i], points2[i], t)
    }
    return result
}

This approach can be extended to work with images by adding color and texture processing.
