Features

2D & 3D Particle Editors

Real-time visual editing with immediate feedback
Separate editors for 2D (PIXI.js) and 3D (Three.js) particles

Particle States System

Create particles with multiple states: Birth → Intermediate → Death
Smooth interpolation between states with custom easing
Control size, color, opacity, speed, rotation, and orbit per state

How the States System Works

Every particle in Particle Studio Pro follows a lifecycle defined by a chain of states, from the moment it spawns to the moment it disappears.

At its core, the timeline always starts with Birth and ends with Death. Between them, you can insert as many intermediate states as you need — each with its own label and duration (in seconds).

Birth defines everything about a particle when it first appears: its size, color, opacity, speed, and rotation. It is always fully declared and serves as the baseline for all properties.

Death defines the final state of the particle before it vanishes. Speed is not redeclared here — it naturally carries over from the previous state.

Intermediate states are deliberately minimal by default. Only the label and duration are set. Every other property — size, color, opacity, speed, rotation — is opt-in. You add only what you want to change.

Sparse Keyframe Interpolation

This is where the system becomes powerful.

Each property interpolates independently through its own keyframe chain, built only from the states that explicitly declare it.

Example:

This means intermediate states act as selective control points — they only affect the properties you explicitly add to them, leaving everything else on its natural trajectory.

Duration & Timeline

Each state's duration carves up the particle's total lifetime. Even if an intermediate state declares nothing, its duration still matters — it shifts the timing of when the next state's keyframes are reached.

Each state also supports a custom easing (Linear, Ease In, Ease Out, Ease In-Out) that controls how smoothly the transition into that state is animated.
