A terra3D scene can consist of several two-dimensional and three-dimensional objects which may contain multiple overlapping information layers to visualize different types of data. Layers can be projected on a spherical, cylindrical or planar surface by applying different projections.

Earth and Clouds
The terrain is formed by an artificial height model of the earth. The data is colored by a colormap depending on the height of the terrain.Original infrared satellite photographs are used for this layer. Again, the data is colored by a colormap depending on the height (i.e. temperature) of the clouds.

Grid and Stream Data
A layer for grid points fields like temperature, uv radiation and ozone. Wind direction and force can be shown as arrows or as a particle system representing the stream process.

Function Overview
  • Weather and landscape visualisation based on a 3D terrain model
  • layering of various information such as terrain data, grid point fields, satellite images, political information or particle systems fir animations of currents
  • OpenGL with 4x antialiasing
  • Keyframe animation
  • Multiple camera types (ortho and various perspective camera) in one scene
  • Dynamic detail levels depending on the zoom factor
  • Up to 8 light sources with changeable position, angle, color and intensity
  • 18 different projections of the earth
  • Image size up to 9000 x 9000 pixels with software rendering
  • Masking of regions and countries
  • Satellite and aerial photo textures can be imported for a more natural display of landscape
