description: Decision framework for particle system projects. Routes to specialized particle skills (gpu, physics, lifecycle) based on task requirements. Use when building particle effects or needing guidance on which particle techniques to combine.

Particles Router

Routes to 3 specialized particle system skills based on task requirements.

Routing Protocol

  1. Classify — Identify particle effect type and scale
  2. Match — Find skill(s) with highest signal match
  3. Combine — Most particle systems need 2-3 skills together
  4. Load — Read matched SKILL.md files before implementation

Quick Route

Tier 1: Core (Always Consider)

Task TypeSkillPrimary Signal Words
Renderingparticles-gpupoints, instanced, buffer, shader, thousands, performance
Motionparticles-physicsgravity, wind, attract, force, velocity, turbulence, collision
Spawningparticles-lifecycleemit, spawn, fade, trail, pool, birth, death, age

Signal Matching Rules

Priority Order

When multiple signals present, resolve by priority:

  1. Performance concern — "millions of particles" → particles-gpu first
  2. Motion type — "swirling", "attracted to" → particles-physics
  3. Emission pattern — "burst", "continuous", "trails" → particles-lifecycle
  4. Default — All three skills usually needed together

Confidence Scoring

  • High (3+ signals) — Route immediately
  • Medium (1-2 signals) — Include all three skills (typical)
  • Low (0 signals) — Ask: "Describe the particle effect you want"

Common Combinations

Basic Particle System (All 3 skills)

code
particles-gpu       → Buffer setup, shader rendering
particles-physics   → Gravity, basic motion
particles-lifecycle → Emission, fade out

Wiring: GPU provides rendering foundation, lifecycle handles spawning/death, physics adds motion.

Snow/Rain Effect (3 skills)

code
particles-gpu       → Points with texture
particles-physics   → Gravity, wind, turbulence
particles-lifecycle → Continuous emission, recycling

Wiring: Lifecycle emits continuously, physics handles falling + drift, GPU renders efficiently.

Explosion (3 skills)

code
particles-gpu       → Instanced or points rendering
particles-physics   → Radial velocity, drag
particles-lifecycle → Burst emission, fade + shrink

Wiring: Lifecycle bursts particles, physics applies outward force + slowdown, GPU handles scale.

Fire/Smoke (3 skills)

code
particles-gpu       → Custom shader with noise
particles-physics   → Upward force, turbulence
particles-lifecycle → Continuous emit, color gradient, size over life

Wiring: Lifecycle manages color/size curves, physics adds flicker motion, GPU renders with blend modes.

Swarm/Flock (2-3 skills)

code
particles-gpu       → Instanced mesh (if 3D shapes)
particles-physics   → Attractors, flow fields, separation
particles-lifecycle → (Optional) Population management

Wiring: Physics dominates with behavioral forces, GPU handles rendering.

Magic Trail (3 skills)

code
particles-gpu       → Points with glow shader
particles-physics   → Follow path, slight randomness
particles-lifecycle → Trail history, fade along length

Wiring: Lifecycle stores position history, GPU renders with alpha gradient.

Confetti (3 skills)

code
particles-gpu       → Instanced flat planes
particles-physics   → Gravity, tumbling rotation, air resistance
particles-lifecycle → Burst emission, ground collision death

Wiring: Physics handles realistic falling, lifecycle manages burst and cleanup.

Particle Count Guidelines

CountApproachSkills Priority
< 100Simple, any approachlifecycle > physics > gpu
100 - 1,000Points or instancedAll equal
1,000 - 10,000GPU-focusedgpu > physics > lifecycle
10,000 - 100,000GPU essentialgpu >> physics (shader) > lifecycle
> 100,000Full GPU/computegpu only, physics in shader

Skill Dependencies

code
particles-gpu (rendering foundation)
├── particles-physics (motion layer)
└── particles-lifecycle (management layer)
  • particles-gpu is always needed for rendering
  • particles-physics and particles-lifecycle are independent but complementary
  • For simple effects, you might skip physics OR lifecycle, rarely both

Fallback Behavior

  • Unknown effect → Start with all three skills
  • Performance issues → Focus on particles-gpu optimization
  • Motion problems → Deep-dive particles-physics
  • Spawning/timing issues → Focus on particles-lifecycle
