This folder contains code for a fast implementation of the BEM acoustics.

format to use the executable:
./main.a --file filename --left left_index --right right_index 
    --low_freq low_frequency --high_freq high_frequency --freq_interp frequency_interpolation 
    --source source_type --low_phi lower_phi --high_phi higher_phi --phi_interp phi_interplation 
    --low_theta lower_theta --high_theta higher_theta --theta_interp theta_interpolation

filename: the name of the file including its suffix. Only supports .obj currently;
left_index: node index of the left ear;
right_index: node index of the right ear;
low_frequency: lower frequency bound;
high_frequency: upper frequency bound;

source type: plane or point;

example:
./main.a  --file guo_equal.obj --left 7269 --right 15533 --low_freq 25 --high_freq 12000
     --freq_interp 25 --source plane --low_phi 0 --high_phi 355 --phi_interp 5 --low_theta 0 --high_theta 135 --theta_interp 5

./main.a  --file guo_equal.obj --left 7269 --right 15533 --low_freq 25 --high_freq 12000
     --freq_interp 25 --source point --low_phi 0 --high_phi 355 --phi_interp 5 --low_theta 0 --high_theta 135 --theta_interp 5
     --radius 1
