Installation

1. Clone the repository:

git clone https://github.com/yourusername/advanced-model-optimizer.git
cd advanced-model-optimizer

2. Set up a local web server (e.g., using Python):

# Python 3
python -m http.server 8000

# Python 2
python -m SimpleHTTPServer 8000

3. Open in browser:

http://localhost:8000/advanced-model-optimizer.html

Usage

1. Loading Models:

   • Click "Choose File" to select your 3D model
   • Supported formats: .fbx, .glb, .gltf, .obj
   • Model is automatically displayed in the viewer

2. Optimization Settings:

   • Target Ratio: Controls the percentage of triangles to keep (1-100%)
   • Error Threshold: Maximum allowed geometric error (0.01-1.0)
   • Normal Weight: Importance of normal vector preservation (0-1)
   • Boundary Weight: Importance of boundary preservation (0-3)

3. Advanced Options:

   • Lock Boundary Vertices: Prevents modification of mesh boundaries
   • Preserve Topology: Maintains mesh connectivity
   • Optimize Vertex Cache: Improves rendering performance
   • Weld Vertices: Merges nearby vertices
   • Generate LODs: Creates multiple detail levels

4. Export Settings:

   • Compress Normals: Uses octahedral normal compression
   • Compress UVs: Quantizes texture coordinates
   • Generate LODs: Creates multiple detail levels

API Reference

Key Functions

// Initialize the optimizer
const modelOptimizer = new AdvancedModelOptimizer();

// Optimization parameters
interface OptimizationSettings {
    normalWeight: number;      // 0.0 - 1.0
    boundaryWeight: number;    // 0.0 - 3.0
    lockBoundary: boolean;     // true/false
    preserveTopology: boolean; // true/false
    optimizeVertexCache: boolean;
    weldVertices: boolean;
    vertexCacheSize: number;   // 8-64
    weldThreshold: number;     // 0.0001 - 0.01
}

Error Handling

The optimizer includes comprehensive error handling:

• Invalid geometry validation
• Non-manifold mesh detection
• Degenerate triangle prevention
• Numerical stability checks

Performance Tips

1. Optimal Settings:

   • Start with 50% target ratio
   • Error threshold of 0.01
   • Normal weight of 0.5
   • Boundary weight of 2.0

2. Large Models:

   • Enable vertex cache optimization
   • Use mesh quantization
   • Consider enabling LOD generation

3. Quality vs Performance:

   • Higher normal weights preserve sharp features
   • Lower boundary weights allow more aggressive optimization
   • Enable topology preservation for animation-ready models
