Hylograph.Internal.Transition.Scene

data EnterBehavior

Transitions describe HOW a scene appears, not just WHAT it contains. By making transitions part of the scene specification, we maintain the declarative philosophy: users describe the desired end state and the library handles all sequencing automatically.

This module provides general-purpose transition types that can be used for any visualization, not just simulations. For simulation-specific scene configuration, see Hylograph.Simulation.Scene. How nodes should appear when they enter the visualization

Constructors

• FadeIn
• ScaleUp
• InstantEnter

data ExitBehavior

How nodes should disappear when they exit the visualization

Constructors

• FadeOut
• ScaleDown
• InstantExit

data UpdateBehavior

How existing nodes should move to new positions

Constructors

• TransitionMove
• InstantMove

type TransitionSpec = { duration :: Number, enterNodes :: EnterBehavior, exitNodes :: ExitBehavior, pinAfterTransition :: Boolean, updateNodes :: UpdateBehavior }

Complete transition specification for a scene Nothing = instant/no transition (backward compatible) Just spec = declarative transition behavior

encodeEnterBehavior :: EnterBehavior -> String

Explicit encoding functions for FFI These ensure we control the string constants passed to JavaScript

encodeExitBehavior :: ExitBehavior -> String

encodeUpdateBehavior :: UpdateBehavior -> String

smoothTransition :: TransitionSpec

Common transition presets Smooth transition with fading and position animation (1.5 seconds) Nodes are NOT pinned - forces will continue to act after transition

smoothTransitionPinned :: TransitionSpec

Smooth transition that pins nodes at their final positions Use this for tree layouts or other layouts where nodes should stay locked

quickTransition :: TransitionSpec

Quick transition with scaling effects (0.5 seconds)

instantTransition :: TransitionSpec

Instant transition (no animation)
