Get3D Lightweighting Performance: Validated Across Five Major Cities
This article presents verified performance data from Get3D’s lightweighting technology across five real-world urban projects. The numbers speak for themselves.
Compression Performance at a Glance
The following data comes from Get3D’s actual urban projects, spanning areas from 52 to 200 square kilometers:
| City | GSD | Area | OBJ Compression Rate | OSGB Compression Rate |
|---|---|---|---|---|
| Kowloon | 6.7cm | 52 km² | 83.3% | 74.5% |
| Xi’an | 3cm | 73 km² | 74.7% | 53.9% |
| Guiyang | 3cm | 81 km² | 77.5% | 77.0% |
| Lanzhou | 3cm | 115 km² | 80.4% | 52.3% |
| Guangzhou | 3+6cm | 200 km² | 68.2% | 62.5% |
Volume Reduction Details
| City | Area | Original OBJ | Lightweighted OBJ | Original OSGB | Lightweighted OSGB |
|---|---|---|---|---|---|
| Kowloon | 52 km² | 106 GB | 19.8 GB | 114 GB | 29.1 GB |
| Xi’an | 73 km² | 294 GB | 74.5 GB | 455 GB | 209.7 GB |
| Guiyang | 81 km² | 875 GB | 197 GB | 820 GB | 246 GB |
| Lanzhou | 115 km² | 769 GB | 151 GB | 537 GB | 256 GB |
| Guangzhou | 200 km² | 1.5 TB | 479 GB | 1.47 TB | 565 GB |
Detailed Cases
Case 1: Kowloon
Reduced to 30.9% of original size with no visible quality loss.
Case 2: Fuyang
Reduced to 30.4% of original size with no visible quality loss.
Case 3: Guiyang
Case 4: Lanzhou
Conclusion
Get3D’s lightweighting technology has proven its exceptional compression capability and fidelity across five major urban scenarios. Whether it’s 52 km² of Kowloon or a 200 km² expanse in Guangzhou, Get3D consistently delivers 60–80% compression rates while maintaining near-lossless visual quality.
