This code implements the method for computing a surface density field from particle data, as described in the paper: Parallel DTFE Surface Density Field Reconstruction, see author section for details. It was developed for computing gravitational lensing effects using the flat-sky approximation from N-body cosmological simulations.
These instructions will get a copy of the project up and running on your local machine for development and testing purposes. Tested on macOSX 10.13.3 High Sierra.
Download SDTFE
git clone git@github.com:steverangel/SDTFE.gitCMake will automatically download the Qhull and libtiff dependencies.
Prerequisites:
- CMake v3.11 or later
- compiler supporting C++14 (for the python extension)
Python library
The python library can be installed with pip from within the SDTFE folder.
The setup.py script will internally call CMake to compile the DTFE library
cd SDTFE
pip install .Executables
To build the executables, create a build directory and run cmake
cd SDTFE
mkdir build && cd build
cmake ..
make -j4Prerequisites:
- This software uses Qhull for the Delaunay triangulation library.
- Optional, but recomended, is libtiff for visualization of the resulting field.
Download and install Qhull.
git clone git@github.com:qhull/qhull.git
cd qhull
makeDownload and install libtiff.
curl -O http://download.osgeo.org/libtiff/tiff-4.0.9.tar.gz
tar xvfz tiff-4.0.9.tar.gz
cd tiff-4.0.9/
mkdir install
./configure --prefix=/your/local/install
make
make installEdit the SDTFE Makefile to link Qhull and libtiff.
cd SDTFE
vim Makefile

QHULLINCDIR = -I../qhull/src/libqhull
TIFFLIBDIR = ../tiff-4.0.9/install/lib
