TeraSurf SDK is a DLL library that allows you to create your own applications. Geomod can also develop these specific applications for you.
We ourselves use this library in many of our applications. Note that there is a Java version of the SDK, used for our applications in Marine Geomatic.
Implementation in Geomod solutions
A .NET C++ DLL library
In particular, TeraSurf SDK includes a very powerful triangulation DLL which has many cropping options (deletion of inner / outer triangles according to their length, deletion of triangles according to the slope), constrained triangulation, automatic creation of contour lines of triangulation breaking horizontal triangles, etc.
It allows for example to triangulate in a few seconds 3 500 000 points with 1.6 GB of memory.
