Quick Start

Basic Animation (Vanilla JavaScript)

import { PoseVCore } from 'posev';

// 1. Create engine
const engine = new PoseVCore({
  debug: true,
  strictValidation: true,
});

// 2. Load movement data
await engine.load({
  movement: './movements/squat.json',
  rig: './rigs/standard-human.json',
});

// 3. Play animation
engine.play();

// 4. Listen to frame updates
engine.on('frameUpdate', (frame) => {
  console.log(`Progress: ${(frame.progress * 100).toFixed(1)}%`);
  console.log(`Current time: ${frame.currentTime.toFixed(2)}ms`);
  
  // Update your UI or renderer here
  renderPose(frame.pose);
});

// 5. Control playback
engine.pause();
engine.seek(0.5); // Seek to 50%
engine.setSpeed(0.5); // Slow motion
engine.play();

// Cleanup
engine.dispose();

Plugin Guide

Writing a Simple Plugin

Create a gait analysis plugin:

import { PoseVPlugin, PluginContext, FrameData } from 'posev';

class GaitAnalysisPlugin implements PoseVPlugin {
  id = 'gait-analysis';
  version = '1.0.0';
  
  private context: PluginContext | null = null;
  private metrics = { stride: 0, cadence: 0, symmetry: 0 };
  
  async install(context: PluginContext) {
    this.context = context;
    console.log('GaitAnalysisPlugin installed');
  }
  
  async activate() {
    console.log('GaitAnalysisPlugin activated');
  }
  
  async deactivate() {
    console.log('GaitAnalysisPlugin deactivated');
  }
  
  onFrameUpdate(frame: FrameData) {
    // Analyze pose data
    const pose = frame.pose;
    
    // Calculate stride length
    const leftFoot = pose.getJoint('left_foot');
    const rightFoot = pose.getJoint('right_foot');
    
    if (leftFoot && rightFoot) {
      const distance = Math.hypot(
        rightFoot.x - leftFoot.x,
        rightFoot.z - leftFoot.z
      );
      this.metrics.stride = distance;
    }
    
    // Calculate cadence (steps per minute)
    this.metrics.cadence = (this.metrics.stride / frame.deltaTime) * 60;
    
    // Emit custom event or update UI
    this.context?.engine.emit('gait:metrics', this.metrics);
  }
  
  getMetrics() {
    return { ...this.metrics };
  }
}

// Usage
const plugin = new GaitAnalysisPlugin();
engine.plugins.install(plugin);

engine.on('gait:metrics', (metrics) => {
  console.log('Stride length:', metrics.stride.toFixed(2), 'cm');
  console.log('Cadence:', metrics.cadence.toFixed(1), 'steps/min');
});

Plugin with Dependencies

class AdvancedAnalysisPlugin implements PoseVPlugin {
  id = 'advanced-analysis';
  version = '1.0.0';
  dependencies = ['gait-analysis'];  // Requires GaitAnalysisPlugin
  
  async install(context: PluginContext) {
    // Install will fail if dependency not available
  }
}

Error Recovery in Plugins

class RobustPlugin implements PoseVPlugin {
  id = 'robust';
  version = '1.0.0';
  
  onFrameUpdate(frame: FrameData) {
    try {
      // Process frame
    } catch (error) {
      // Log but don't crash
      console.error('Plugin error:', error);
    }
  }
  
  // Return true to suppress error propagation
  onError(error: PoseVError) {
    if (error.code === 'P_5004') {
      // Handle specific error
      return true; // Suppress
    }
    return false; // Propagate
  }
}

Schema Requirements

interface MovementJSON {
  // Version and metadata
  version: '1.0.0';
  metadata: {
    id: string;                    // Unique identifier
    name: string;                  // Human-readable name
    description?: string;
    author?: string;
    captureDate?: string;
    
    fps: number;                   // Frame rate (30-120)
    duration: number;              // Total duration in ms
    units?: 'centimeters' | 'meters' | 'inches';
  };
  
  // Rig reference
  rig: {
    id: string;
    version: string;
  };
  
  // Keyframes (minimum 2)
  keyframes: Array<{
    time: number;                  // Time in ms (0 to duration)
    joints: {
      [jointId: string]: {         // One entry per joint in rig
        x: number;
        y: number;
        z: number;
      };
    };
  }>;
  
  // Animation settings
  interpolation?: 'linear' | 'cubic';  // Default: 'linear'
  loops?: boolean;                     // Default: true
  tags?: string[];                     // Categorization
}

Validation Rules

• Time Values

  • First keyframe must be at time 0
  • Last keyframe must be at duration
  • Times must be monotonically increasing
  • No duplicate times

• Joint Coverage

  • Every keyframe must have all rig joints
  • Extra joints are ignored
  • Missing joints cause validation error

• Coordinate Ranges

  • Values typically -500 to +500 (units)
  • No NaN, Infinity, or undefined
  • Positive Z is forward, Y is up

• Duration

  • Minimum: 100ms
  • Maximum: 300,000ms (5 minutes)
  • Recommended: 500ms - 30,000ms

Creating Movement Data

import { MovementValidator } from 'posev';

const movementData = {
  version: '1.0.0',
  metadata: {
    id: 'jump',
    name: 'Standing Jump',
    fps: 60,
    duration: 1200,
  },
  rig: { id: 'standard-human', version: '1.0.0' },
  keyframes: [
    { time: 0, joints: { /* ... */ } },
    { time: 600, joints: { /* ... */ } },
    { time: 1200, joints: { /* ... */ } },
  ],
};

// Validate before use
const validator = new MovementValidator();
const result = validator.validate(movementData);

if (result.valid) {
  console.log('✅ Movement data is valid');
} else {
  console.error('❌ Validation errors:', result.errors);
}

Rig System

Overview

A rig defines the skeletal structure and constraints for animations. PoseV ships with predefined humanoid rigs and supports custom rigs.

Standard Humanoid Rig (v1.0.0)

The default rig with 17 joints and 16 bones:

Root (pelvis)
├── Spine
│   └── Chest
│       ├── Left Shoulder
│       │   └── Left Arm
│       │       └── Left Forearm
│       │           └── Left Hand
│       └── Right Shoulder
│           └── Right Arm
│               └── Right Forearm
│                   └── Right Hand
├── Left Hip
│   └── Left Knee
│       └── Left Ankle
│           └── Left Foot
└── Right Hip
    └── Right Knee
        └── Right Ankle
            └── Right Foot

Joint IDs:

root, spine, chest,
left_shoulder, left_arm, left_forearm, left_hand,
right_shoulder, right_arm, right_forearm, right_hand,
left_hip, left_knee, left_ankle, left_foot,
right_hip, right_knee, right_ankle, right_foot

Using Built-in Rigs

import { StandardHumanRig, CompactHumanRig } from 'posev';

// Standard rig (17 joints, full detail)
const rig = new StandardHumanRig();

// Compact rig (11 joints, optimized)
const compactRig = new CompactHumanRig();

// Access rig data
const joints = rig.joints;
const bones = rig.bones;

// Query hierarchy
const parent = rig.getParent('left_knee'); // 'left_hip'
const children = rig.getChildren('spine');  // ['chest']

// Validation
const validation = rig.validate();
if (!validation.valid) {
  console.error(validation.errors);
}

    // ... more joints
  ],
  bones: [
    {
      id: 'front_left_femur',
      from: 'front_left_leg',
      to: 'front_left_knee',
      minLength: 10,
      maxLength: 25,
      idealLength: 17,
    },
    // ... more bones
  ],
});

// Use with movement data
const movement = await engine.load({
  movement: './movements/walk.json',
  rig: customRig,
});

const validation = rig.validate();

if (!validation.valid) {
  console.error('Rig errors:');
  validation.errors.forEach(error => {
    console.error(`  - ${error.joint}: ${error.message}`);
  });
}

// Validate specific pose
const poseValidation = rig.validateBoneLengths(pose);
if (!poseValidation.valid) {
  poseValidation.violations.forEach(v => {
    console.warn(`Bone ${v.bone} length ${v.actual}cm exceeds max ${v.max}cm`);
  });
}

// Validate angles
const angleValidation = rig.validateAngles(pose);
angleValidation.violations.forEach(v => {
  console.warn(`Joint ${v.joint} angle ${v.actual}° exceeds max ${v.max}°`);
});

Rig Hierarchy Queries

// Get all ancestors
const ancestors = rig.getAncestors('left_foot');
// → ['left_ankle', 'left_knee', 'left_hip', 'root']

// Get all descendants
const descendants = rig.getDescendants('root');
// → [all joints in tree]

// Check relationship
const isDescendant = rig.isDescendant('left_foot', 'root');
// → true

// Get bone connecting two joints
const bone = rig.getBone('left_hip', 'left_knee');
// → { id: 'left_femur', ... }

Performance & Production

Bundle Optimization

PoseV uses aggressive tree-shaking and minification:

ESM: 24.2 KB gzipped (79.6% compression)
UMD Min: 13.7 KB gzipped (73% compression)

Performance Budgets

Mobile-first conservative targets:

Metric	Target	Status
Frame Time	<16.67ms (60 FPS)	✅
Memory	<50 MB	✅
Load Time	<5 seconds	✅
Max Keyframes	10,000	✅

Error Handling

23 predefined error codes across 6 categories:

import { ERROR_CATALOG, ErrorHandler } from 'posev';

const handler = new ErrorHandler();

try {
  await engine.load(manifest);
} catch (error) {
  handler.handle(error);
  
  if (error.retryable) {
    // Implement exponential backoff retry
    setTimeout(() => engine.load(manifest), 1000);
  }
  
  console.log(handler.getReport());
}

Monitoring

Real-time performance monitoring:

import { PerformanceMonitor } from 'posev';

const monitor = new PerformanceMonitor();

engine.on('frameUpdate', (frame) => {
  monitor.recordMetric({
    fps: 60,
    frameTime: 16.7,
    memoryUsage: 42,
    cpuTime: 14.5,
    renderTime: 2.2,
  });
});

// Check for violations
const status = monitor.getBudgetStatus();
if (!status.compliant) {
  console.warn('Performance degradation:', status.violations);
}

// Generate report
console.log(monitor.getReport());
