CubicEaseIn()

static constexpr Fxp SRL::Math::Interpolation::CubicEaseIn ( const Fxp & start, const Fxp & end, const Fxp & t )

inlinestaticconstexpr

Cubic ease-in interpolation for stronger acceleration.

Implements cubic easing using the formula: t³

The easing produces this motion:

• Very slow start
• Rapid acceleration
• Maximum velocity at end

Common uses:

• Dramatic entrances
• Power-up effects
• Explosion start
• Heavy object movement

Parameters

start	Starting value of the interpolation
end	Ending value of the interpolation
t	Interpolation factor in range [0,1]

Returns

Eased value

Note

More pronounced than quadratic EaseIn
