Lerp()

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

inlinestaticconstexpr

Linear interpolation between two fixed-point values.

Performs linear interpolation (lerp) between start and end values using the formula: result = start + (end - start) * t

The interpolation follows this pattern:

• When t = 0, returns start
• When t = 1, returns end
• When t = 0.5, returns the midpoint

Common uses:

• Camera movement
• UI element transitions
• Color blending
• Position interpolation

Parameters

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

Returns

Interpolated value

Note

For best performance, ensure t is pre-clamped to [0,1]
