Three Platforms, Three Philosophies
The industrial simulation market has consolidated around three major real-time 3D platforms: Unity, Unreal Engine, and NVIDIA Omniverse. Each represents a fundamentally different philosophy about how industrial software should work.
| Factor | Unity | Unreal Engine | Omniverse |
|---|---|---|---|
| CAD Integration | PiXYZ plugin | Datasmith | Omniverse converter |
| Visual Quality | Closing gap rapidly | High-fidelity | Photorealistic |
| Distribution | Cross-platform (iOS, Android, WebGL, Windows, Linux) | Cross-platform | Server-dependent |
| Runtime Licensing | No fees for delivered products | Potentially costlier | Cloud/proprietary dependency |
| Developer Access | C# scripting, huge ecosystem | Less accessible for industrial users | Unfamiliar platform |
Why We Chose Unity
Four reasons drove our decision to build realvirtual.io on Unity:
- Vendor independence: No dependency on a single hardware or cloud vendor
- Platform portability: Same project deploys to desktop, WebGL, mobile, and VR – without complex server rendering
- License-free distribution: Deliver compiled applications to end customers without runtime fees
- Developer accessibility: C# is familiar to automation engineers; the Unity ecosystem has millions of developers and assets
Visual fidelity matters, but for industrial use cases, deployability and accessibility matter more. A photorealistic render that only runs on a dedicated GPU server is less useful than a good-looking simulation that runs in any browser.
