The Finnish 3D graphics company Umbra showed a demo of their solution to import massive 3D models to Unity or Unreal engine. Umbra automatically optimises huge 3D models to run real-time in virtual reality. The software works with custom game engines and on all platforms from mobile to consoles.
Umbra showed a scene where they had imported the 3D model of Boston from Google Earth to Unity. You are flying high above the rooftops. The data set is gigantic. The size of the map is something like 10*10 kilometres. The size of the uncompressed data set was about 200GB. Umbra software processed the data to the Unity in two hours.
The demo was running on an average gaming computer and Oculus Rift DK2, but developers told me it runs also on laptops. The textures looked as good as the ones in Google Earth. There were no problems with fast head movements. Everything looked surprisingly sharp from near to far! The demo is running smoothly in Unity at 90fps.
A quote from umbra3d.com explains the technology:
Umbra uses the visibility data to figure out what part of the scene needs to be streamed in, and then what needs to be rendered on the screen. If something is guaranteed to be hidden it needn’t be loaded into memory.
The Umbra database contains multiple versions of the geometry and textures at different levels of detail and the appropriate resolution of the data is chosen based on distance and visibility – higher resolution is needed close to the viewer, while far away objects can use lower resolution.
Umbra is now looking for even more difficult use cases for the software. The company is planning to support BIM (Building Information Model) and 3D scanned point cloud imports in the future.
Umbra is a Helsinki-based company founded in 2006. Many AAA games including Call of Duty: Advanced Warfare, Batman Arkham Knight, Quantum Break already use Umbra´s solutions.
Umbra closed a $3,4M funding
Umbra announced that they closed a $3,4M Serie A funding from investors including Inventure, Lifeline Ventures and Initial Capital.
