Terrain

Unigine provides realistic terrain which can be designed and created manually or procedurally generated on the basis of geospatial data.

In Unigine, terrain is implemented as 2 types of objects:

•   Landscape Terrain that allows reconstructing practically any arbitrary landscape with diverse features:
  • Virtually infinite terrain surface
  • Extreme details up to 1 mm per pixel
  • Adaptive hardware tessellation with displacement mapping
  • Dynamic modification at run time - craters, funnels, trenches
  • Simple and clear API
  • Up to 1024 detail materials
  • Layers system with flexible blending rules
  • Binoculars/scopes support (x20 / down to 1-degree FOV)
  • Optimized rendering and physics performance
  • Support for simultaneous editing by a team of 3D artists
  • Decal-based holes

  Landscape Terrain is recommended for ground operations (especially with scopes/binoculars required or where runtime modification is a must) or projects where extreme level of details is required (including helicopter simulation).

•   Global Terrain is a virtually limitless terrain representing a certain fragment of Earth's surface generated on the basis of ordinary raster images and/or GIS data. It is recommended for large-scale flight simulation purposes (especially fixed wing) on georeferenced scenarios. Appearance of the global terrain object is determined by the accuracy and availability of source data. Features:
  • Limitless terrain which can cover the whole Earth's surface.
  • Plain or hilly relief based on imported height maps.
  • Realistic surface coverings (grass, rocks, dirt) created by means of Terrain Global Details.
  • Landcover masks used for Details and Vegetation.
  • Decal-based holes.
  • Physical interaction with scene objects.
