Fade is distributed under two licenses:

  • The free student license is already included in the download. Use it for non-commercial scientific research and for time limited commercial evaluation purposes (see below).
  • The commercial license for professional users. Fade2D/2.5D has been designed for an industrial environment. Fade is fast enough to triangulate many millions of points: It is robust, it is actively maintained and there is support.

Student license

Fade is not a free software. But the student license is free of charge for personal non-commercial scientific research and you can use it without registration. When you use Fade in your software,

  • Please put a link to Fade on your research page or your project homepage.
  • Describe and cite Fade in scientific publications for which you have used it.
  • Make sure that others do not use the software in a commercial setting.

It is common and permissible to use the included student license even in commercial development for a short time for the initial tests. But if you are developing with Fade for a longer period of time, please contact us for an evaluation license.

Commercial license

All other applications, including commercial in-house usage, require a commercial license which has the advantage of maintenance, error corrections and personal support. The commercial license of Fade consists of several parts:

  • The Fade2D base component (mandatory): It covers 2D Delaunay triangulations, constrained Delaunay triangulations (insertion of segments) and the Segment Checker
  • The Quality Mesh Generator (optional): Delaunay Meshing and Grid Meshing refines meshes to achieve well shaped triangles. You might have a look at the article Advanced Mesh Generation
  • The Fade2.5D extension (optional): This is for 2.5D point clouds i.e., for terrains and other height fields: Points have (x,y,z)-coordinates and there is a bunch of additional algorithms like ISO line computation, height queries, point cloud simplification, valley-ridge-optimization, 2.5D segment checking. Existing triangles can be imported and trimmed.
  • The Cut&Fill software for earthwork calculations (optional): Cut-And-Fill computes the volume between two overlapping TIN’s.

For a commercial license please contact the author. Please describe your software project briefly and tell us which fade components you would like to use.

In no case can we be made responsible for damages of any kind that arise in connection with the use or non-usability of our software or the information provided on our internet pages. If you don’t accept these terms, you are not allowed to use our software. Using Fade2D or Fade2.5D for military research and applications is not accepted.
