TerraLand - Rendering of 4k heightmap & 32k imagery Terrain in Unity
Here is the rendering of 40 x 40 km terrain surface of Monument Valley, USA.
TerraLand's Offline Streaming system dynamically loads elevation & imagery data from a local server.
In this demo, the scene contains 1024 (grid of 32x32) data files placed in a local hard drive location as a geo-server. The server has been created automatically by TerraLand.
Tiles will be streamed and rendered in realtime on demand around the player to sustain performance and memory footprint while dealing with huge amount of data in a server.
Using TerraLand's Offline Streaming system, huge open world environments can be created and edited at runtime. This is what could never be achieved with traditional terrain loading, which loads the whole dataset at the level start.
Our test with this demo showed approx. 14 gigabytes of data is needed to be populated in memory in order to generate the entire surface at level start, which will eventually cause crash on any machine.
Thanks to the dynamic system in TerraLand Offline Streaming, this limitation is lifted and unlimited amount of data can be fed into the scene in a chunk by chunk loading behavior.
