+# Summary
+
+The Python library startinpy allows us to model and process terrains with a triangulation. 
+This is used to represent the morphology of a given area (hills, valleys, but buildings and other man-structures can be included) by using elevation points and to derive and calculate properties from that triangulation.
+
+A terrain library
+
+(which are 2.5D objects) using a two-dimensional Delaunay triangulation.
+This means that while a triangulation is computed in 2D, the *z*-elevation of the vertices are kept.
+
+Such a library is necessary to represent the morphology of an area, when one wants to avoid using grids and prefers a leaner representation with points and triangles.
+
+The underlying code of startinpy is written in the language Rust (so it's rather fast) and robust arithmetic is used (so it shouldn't crash).
+
+startinpy uses the [startin Rust library](https://github.com/hugoledoux/startin) and adds several utilities and functions, for instance [NumPy](https://numpy.org/) support for input/output, exporting to several formats, and easy-of-use.
+
+
+# Statement of need
+
+- 2D DT and difficult to keep the z-values, especially with xy-duplicates
+- 3D DT is the solution
+- 2.5D specific triangulation == no idea how
+- only batch operation available, that is you give a certain of points and you get a list of triangles.
+- but for many apps one wants to modify this triangulation (to simplify it by removing least important points + perform interpolations + add points somewhere else where more differences in elevation)
+- SciPy has only batch, hte incremental is buggy and is very slow
+- Triangle from Shewchuk is not 2.5D and complex to manage
+
+
+# Functionalities of startinpy
+
+startinpy is incrementation insertion, deletion is possible, and is using NumPy for i/o so that it is easy to pair with laspy and others libraries.
+
+
+Several functions that are usful

+Figures can be included like this:
+![Caption for example figure.\label{fig:example}](figure.png)
+and referenced from text using \autoref{fig:example}.
+
+Figure sizes can be customized by adding an optional second parameter:
+![Caption for example figure.](figure.png){ width=20% } -->
