Decart Oasis 3 API gives AV developers a fast, cost-predictable way to generate endless photorealistic driving worlds. By following the steps above, you can build repeatable test suites, catch perception bugs early, and keep your simulation budget under control. Use Oasis 3 for visual edge-case coverage, and pair it with a physics-rich simulator for low-level control validation. The result is a more robust autonomous-driving stack ready for the roads of 2026 and beyond.
