mesh2scattering 0.1.4

Numerical calculation of surface scattering

Mesh2scattering is based on Mesh2HRTF and is an open-source project aiming an easy-to-use software package for the numerical calculation of scattering pattern and scattering and diffusion coefficients of any surface. In a nutshell, Mesh2scattering consists of three parts:

• input: prepares geometrical data and acoustic parameters for the simulation,

• numcalc: based on the input from input, it calculates the corresponding sound field

• output: processes the output from NumCalc to scattering pattern.

• process: processes the output to scattering and/or diffusion coefficients.

• utils: helping functions.

Please notice that this project does not support HRTF post processing, use Mesh2HRTF instead.

Getting Started

Check out the examples folder for a tour of the most important mesh2scattering functionality and read the docs for the complete documentation.

Installation

Use pip to install mesh2scattering

$ pip install mesh2scattering
$ pip install git+https://github.com/pyfar/imkar.git@scattering-freefield

(Requires Python 3.8 or higher)

Note that NumCalc need to be build on Linux and MacOS. For Windows it can be downloaded.

for Linux:

• Install the C++ build essentials by running

$ sudo apt-get install build-essential

• Go into the NumCalc directory by running

$ cd path/to/your/Mesh2scattering/mesh2scattering/numcalc/src

• Compile NumCalc by running make. It is now located in the folder mesh2scattering/numcalc/bin

$ make

• Copy NumCalc to a folder in your program path: in the same directory run

$ sudo cp NumCalc /usr/local/bin/

• Now NumCalc can be used by running NumCalc (don’t do this yet).

for MacOS:

• Install the C++ build essentials by installing xcode

• Go into the numcalc/src directory by running

$ cd path/to/your/Mesh2scattering/mesh2scattering/numcalc/src

• Compile NumCalc by running make. It is now located in the folder mesh2scattering/numcalc/bin

$ make

• Now NumCalc can be used by running path/to/mesh2scattering/numcalc/bin/NumCalc (don’t do this yet)

$ path/to/mesh2scattering/numcalc/bin/NumCalc

for Windows:

download the executable from the release.
