Automated Topology Optimization with TripoSR: High-Efficiency 3D Model Processing

This article is part of the TripoSR Technical Series, focusing on practical applications of topology optimization.

Why Intelligent Topology Optimization?

In modern 3D content creation, we frequently encounter these challenges:

High-polygon models from photogrammetry (10M+ polygons)
Complex geometry from CAD model conversions
Real-time rendering performance bottlenecks
Mobile 3D application resource constraints

Traditional simplification methods show significant limitations:

# Traditional edge collapse method
mesh.simplify_mesh(
    target_reduction=0.7,    # 70% polygon reduction
    preserve_border=True,    # Maintain boundaries
    verbose=True            # Output logs
)

Implementation Guide

1. Preparation

# Model analysis
triposr analyze --input model.fbx --report

2. Optimization Configuration

config = {
    "platform": "mobile",     # Mobile optimization
    "target_faces": 50000,    # Target face count
    "texture_size": 2048,     # Texture resolution
    "uv_optimization": True   # UV optimization
}

3. Execute Optimization

from triposr import Pipeline

pipeline = Pipeline(config)
result = pipeline.optimize("input.fbx")
result.export("optimized.glb")
