DelaunayTessellationFieldEstimator.jl

What is it?

This package is an implementation the DTFE algorithm (Schaap, 2007 PhD) for calculating an estimate of a particle density field (can be used for other fields too if the 'mass' is some another physical attribute).

Dependent on

• GeometriclPredicates.jl
• VoronoiDelaunay.jl

Current limitations

• Currently 2D since VoronoiDelaunay.jl is and everything is based on this.

• 'Due to numerical restrictions the point coordinates must be within min_coord <= x <= max_coord where min_coord=1.0+eps(Float64) and max_coord=2.0-2eps(Float64). Note this is a bit different than what is required by the GeometricalPredicates package.' - Quote VoronoiDelaunay.jl

TODO

• Nice and easy plotting + movie making :)
• 3D, would need VoronoiDelaunay.jl updated.
