Hands-on with Umbra in Unity - Past, Present and the Future
- 1. Hands-on with Umbra in Unity Past, Present and the Future
- 2. Umbra the company • 3D rendering optimization tech for games (and other industries) • Founded in 2006 • 25 employees • HQ in Helsinki • Branches in San Francisco and Seattle
- 4. Trusted partner in gaming • Billion dollar game franchises • Leading game engines • Over 125 released titles • Top selling games use Umbra
- 6. Occlusion Culling - Why Bother?
- 7. Umbra 3 Overview POLYGON SOUP VISIBLE OBJECTS Occluder generation Queries SPATIAL DATABASE
- 8. Polygon Soup
- 9. Voxels
- 11. Visibility Query Rasterize portal graph
- 12. Occlusion Buffer
- 13. Umbra 3’s Unity UI • Occlusion Culling Panel • UI can be found from Window - > Occlusion Culling • Three parameters •Smallest Occluder •Smallest Hole •Backface Threshold
- 14. Smallest Hole More detailed input geometry Slower bake Higher bake memory usage Less detailed input geometry Faster bake Lower bake memory usage
- 16. Backface Threshold Input: Less visible backfaces in the scene Output: Smaller occlusion data Output: More undefined areas Larger occlusion data More visible backfaces in the scene Less undefined areas
- 17. Content Creation Guidelines • Understanding the Smallest Hole • Smallest opening you can see through • Plug modeling errors • Smaller value: longer computation time • Manually tagging bad occluders • Things with mostly small holes • Avoiding leaks in occluder geometry • Don’t let the visibility to leak under the terrain
- 18. Wait, there is more? Introducing Umbra 4
- 19. 3D Content is Growing Rapidly • The entire world is being scanned and modeled in 3D • Creation of 3D virtual worlds is growing massively • Developments in hardware and software support the growth
- 20. • Significant possibilities for industries outside of gaming to benefit from real-time 3D rendering • Construction, architecture, engineering, mapping, navigation etc. Increase of Demand for Real-time 3D
- 21. LIMITED BANDWIDTH LIMITED MEMORY AND PROCESSING CAPACITY UNLIMITED DATA
- 22. Existing Solutions Using ad-hoc methods and hand optimization are ineffective.
- 23. 100 GB MANUAL WORK FROM EXPERTS 100 MB
- 24. Umbra 4 – Any 3D content, any device
- 25. UNLIMITED DATA UMBRA 100 MB • Umbra automatically organizes source data for transmission and display
- 26. It all starts with the user creating 3D content How It Works
- 27. Inside the editor they can “umbrafy” the content. This means the content is sent to the Umbra Cloud
- 28. Umbra then automatically restructures the data... ... and creates an optimized 3D database.
- 29. When the application is running, Umbra will... ...tell what to render next with 3D content streaming ...report what is visible with occlusion culling ...define which version of assets to use (level of detail)
- 30. Umbra Roadmap Universal 3D viewer – streaming any content to any device Revit integration Viewer H1 2017 Unity integration Pilot users from AEC and games Hololens VR Beta now Integrate into new toolchains and file formats Collaborative design and review of large 3D models WebGL SDK H2 2017
