Terragen offers you the rendering and modeling tools to create
photo-realistic landscape images and animations. You can apply special effects
for making the landscape more attractive. While creating a landscape, you can
control the weather, lakes, stars and the shader networks used for terrain,
textures, clouds, etc. The user-friendly interface lets you navigate through
tools such as, Object, Terrain, Shaders, Water, Atmosphere, etc without any
difficulty. Some of the good features of Terragen 2 include Hybrid micropolygon
renderer used for large landscapes, export high resolution objects, import 3D
objects for rendering, render millions of plants, 3D painting of colors and
masks, etc. Available for both Win and Mac, the application is free for personal
use with few limitations. Here, we create a landscape comprising sky, water and
terrain.
