## IntroductionCosmoToolbox is a C++ library which I have implemented for solving specific programming problems that I met while doing my research in cosmology. It is a random set of codes that I have abstracted to be reusable in a number of situations. The following code are implemented: - loading snapshot files from Ramses and Gadget 1 & 2 snapshots
- reading and writing unformatted fortran binary file
- building and walking through KD-Trees (simple and leaf)
- a general 1d interpolation
- a tri-linear 3d interpolator
- interpolating on a Delaunay tesselation
- adaptive smoothing (Colombi, Chodorowski & Teyssier 2007, ArXiV)
- Compute the linear growth factor for different cosmologies
- A wrap-up around NetCDF to quickly dump large arrays and load them in Yorick (http://yorick.sourceforge.net)
- a general purpose queue handler, for which the queue may only achieve a maximum length (this is useful for implementing KD-Tree)
Here is a list of the currenly available classes and/or modules (when available a link to the documentation page is included): - KDTree
- Simulation loading
- Interpolate
- Interpolate3D
- Cosmology (power spectrum, growth factor)
- Adaptive smoothing
- Yorick I/O
- easy HDF5 array I/O
- python bindings to read/write simulation snapshots, cosmology power spectrum, etc.
## Building instructionsCosmoToolbox uses CMake for the building machinery. ## Getting cosmotoolCosmoTool is in continuous development. It is available in the bitbucket repository https://bitbucket.org/glavaux/cosmotool . (C) Guilhem Lavaux, 2014 - 2017, Last updated: November 05, 2017 |
