Fluviz
is a spatial data processor that has been written as a companion for
twodimensional
flow modelling tools (e.g. Flumen, Hydro2de, TriPaD).
It consists of modules for the generation of structured data sets from scattered data points.
The code can be used to edit existing sets (e.g. topographical data) and performs calculations with given sets.

Data Editing
and Altering
 cutting points and vertices
 contour query
 data operations (+,,*,/,<,>)
 closed polygon editing


Data Filtering
 buffering (removing points near edges)
 cutting equal nodes
 closing polygons
 weeding of vertices (with DouglasPeukert algorithm)


Surface
Interpolation (Gridding)
 nearest neighbour
 distance weighted and quadrant search
 constrained Delaunay triangulation


Mapping and
Data Query
 mapping of nodes to given TIN
 mapping sections to given TIN
 extracting river sections from TIN surfaces


 since version 3.0:
 unlimited mesh sizes (depending on system RAM)
 generation of optimised meshes with variable cell areas (CFLcondition)

Fluviz
is based on the grafic library GraficV3 (copyright MIT). The
triangulation
is performed with the program Triangle.

manuals for more details.
