C++ implementation of Adaptive Rectangular Decomposition (ARD) with frequency dependent atmospheric absorption in 2.5D (3D with constant height).
Theory:

Extended from ARD-simulator by @jinnsjj.
assets/*.txt records the structure of room on x-y plane. Note that this simulator only supports 2.5D room geometries: z should always be 0 and depth of all partition should be equal.
Input example:
partition:
0 0 0 3 3 3 <- partition 0: x, y, z, width, height, depth
3 0 0 3 3 3 <- partition 1: x, y, z, width, height, depth
source:
1 1 1 <- source 0: x, y, z
recorder:
1 1 1 <- recorder 0: x, y, z
All the values above are in real world scale (meter).
Don't forget to add an extra blank line at the end of file.
- Frequency dependent atmospheric absorption
- Partial absorbing boundaries through PML partitions
- Test cases included
Use Visual Studio to build. The solution itself is self-contained, so simply building and running in Visual Studio should work. Win32 mode may cause performance issue, please run under x64 mode.
