地形

Unigine provides realistic terrain which can be designed and created manually or procedurally generated on the basis of geospatial data.Unigine提供了真实的地形，可以在地理空间数据的基础上手动设计和创建或程序生成。

In Unigine, terrain is implemented as 2 types of objects:在Unigine中，地形被实现为两种类型的对象:

•   Landscape Terrain 几乎可以重建具有多种特征的任意景观:
  • Virtually infinite terrain surface实际上是无限的地形表面
  • Extreme details up to 1 mm per pixel极端细节高达1毫米每像素
  • Adaptive hardware tessellation with displacement mapping自适应硬件镶嵌与位移映射
  • Dynamic modification at run time - craters, funnels, trenches运行时的动态修改-弹坑，漏斗，沟槽
  • Simple and clear API简单明了的API
  • Up to 1024 detail materials多达1024个细节材质
  • Layers system with flexible blending rules层系统与灵活的混合规则
  • Binoculars/scopes support (x20 / down to 1-degree FOV)双筒望远镜/望远镜支持(x20 /下降到1度视场)
  • Optimized rendering and physics performance优化渲染和物理性能
  • Support for simultaneous editing by a team of 3D artists支持同步编辑的一个团队的3D艺术家
  • Decal-based holesDecal-based洞

  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).Landscape Terrain建议地面行动(尤其是范围/双筒望远镜要求或在运行时修改是必须的)或项目中极端程度的细节要求(包括直升机仿真)。

•   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.Limitless terrain which can cover the whole Earth's surface.
  • Plain or hilly relief based on imported height maps.Plain or hilly relief based on imported height maps.
  • Realistic surface coverings (grass, rocks, dirt) created by means of Terrain Global Details.Realistic surface coverings (grass, rocks, dirt) created by means of Terrain Global Details.
  • Landcover masks used for Details and Vegetation.Landcover masks used for Details and Vegetation.
  • Decal-based holes.Decal-based holes.
  • Physical interaction with scene objects.Physical interaction with scene objects.

  • Limitless terrain which can cover the whole Earth's surface.可以覆盖整个地球表面的无限地形。
  • Plain or hilly relief based on imported height maps.平原或丘陵地形的基础上输入的高度地图。
  • Realistic surface coverings (grass, rocks, dirt) created by means of Terrain Global Details.通过Terrain Global Details创建的逼真的表面覆盖物（草，岩石，灰尘）.
  • Landcover masks used for Details and Vegetation.用于细节和植被的土地覆盖遮罩。
  • Decal-based holes. 基于贴花的孔 。
  • Physical interaction with scene objects.物理与场景对象交互。
