In order to show the flexibility, performance & customization of the Offline Streaming system plus utilizing TerraLand's built-in tools, here is the rendering demo of high resolution 1 meter Lidar data from Alaska.
Total terrain surface in the demo is around 7x7 kilometers spread and resampled in a 8192 pixel resolution heightmap tiled into a 32x32 grid as 1024 heightmap tiles using "TerraLand Terrain" component. Each elevation tile is 257x257 pixels.
Active area around the player is a grid of 8x8 as 64 tiles covering approx. 1.7 km2 which is streamed dynamically while traveling.
No Satellite Images are used in the demo and the colors on terrain surface is procedurally generated using a custom terrain shader which involves a simple hack for texturing.
The original 1 meter Lidar TIN data is obtained from http://www.opentopography.org/
The purpose of this demo is to show the possibilities of TerraLand tools without even leaving Unity and to show the rendering power and the performance of the high resolution terrain surfaces in huge open world environments created by the Offline Streaming system in Unity.
The Lidar data is used as raw capturing of the point cloud data on the surface to contain all 3D features such as trees. The existing 3D features on the surface will give players a sense of scale and visual fidelity.
The existence of raw 3D features on the surface in the demo is similar to a basic version of Google Earth's 3D Imagery technique.
