import "github.com/rfwlab/rfw/v2/animation"

Animation primitives for rfw. Provides keyframe-based animation system.

Keyframe

type Keyframe struct {
    Time   float64
    Easing func(float64) float64
}

Animation frame at a specific time with easing function.

Easing Functions

Function Description
Linear(t float64) float64 No easing
EaseIn(t float64) float64 Ease in (quadratic)
EaseOut(t float64) float64 Ease out (quadratic)
EaseInOut(t float64) float64 Ease in-out (quadratic)
Bounce(t float64) float64 Bounce effect
Elastic(t float64) float64 Elastic effect

Lerp Functions

Function Description
LerpFloat(a, b, t float64) float64 Linear interpolation
LerpVec2(a, b m.Vec2, t float64) m.Vec2 Vector interpolation
LerpVec3(a, b m.Vec3, t float64) m.Vec3 3D vector interpolation
LerpQuat(a, b m.Quat, t float64) m.Quat Quaternion interpolation
