Method Slerp

Source/Engine/Core/Math/Vector2.h:562–569

Performs a spherical linear interpolation between two vectors.

    // Performs a spherical linear interpolation between two vectors.
    static void Slerp(const Vector2Base& start, const Vector2Base& end, T amount, Vector2Base& result) 
    {
        T dot = Math::Clamp(Dot(start, end), -1.0f, 1.0f);
        T theta = Math::Acos(dot) * amount;

        relativeVector.Normalize();
        result = ((start * Math::Cos(theta)) + (relativeVector * Math::Sin(theta)));
