| Summary: | Rendering large city models with high polygon count and a vast amount of textures at interactive frame rates is a rather difficult to
impossible task as it highly depends on the client hardware, which is often insufficient, even if out-of-core rendering techniques and
level of detail approaches are used. Rendering complex city models on mobile devices is even more challenging. An approach of
rendering and caching very large city models in the cloud using ray-tracing based image provisioning is introduced. This allows
rendering large scenes efficiently, including on mobile devices. With this approach, it is possible to render cities with nearly
unlimited number of polygons and textures. |
