Physical Sound

Tao stringed instrument simulation

http://taopm.sourceforge.net/examples/sounds.html

(uploaded to github https://github.com/MindBuffer/tao - did they import version history? It doesn't look like it.)

Could convert to CMake.

sudo apt install libaudiofile-dev

cd tao
make distclean  # build artifacts were checked into source
cd ..
mkdir build_tao
cd build_tao
../tao/configure --prefix=$HOME/other/install
make

../../tao/libtao/Tao.cc: In member function 'void Tao::main(int, char**)':
../../tao/libtao/Tao.cc:156:14: error: 'EOF' was not declared in this scope
  if (option==EOF) break;

-> https://github.com/lucasw/tao build_ubuntu branch makes it build, but can't get examples to work:

Syntax error: Bad fd number

The contents of include didn't get installed, copy them to $HOME/other/install/include/tao manually

mkdir $HOME/other/install/include/tao
cp include/*.h /home/lucasw/other/install/include/tao

taoparse looks to have worked fine and generates a .cc file, just need to compile it. The tao script could easily be replaced.

taoparse test.tao > test.cc

g++ -O2 -I$HOME/other/install/include/tao -L$HOME/other/install/lib -DSCRIPTNAME=test.cc -o test.exe test.cc -ltao -lX11 -lXmu -lXi -lGL -lGLU -lpthread -lglut -lm

Ardour?

Some of the branches on the official github are much more recent.

Probably should try 3.0 (most recently updated) or 3.1.

3.0 build with qmake but takes 100% cpu doing nothing but drawing the ui.

Tried to run simulation:

sh: 1: OpenPSTD-cli.exe: not found
Floating point exception (core dumped)

OpenPSTD 2.0 master branch

Same as the screenshot above.

Most attempts to change from default room then simulate result in crash:

=Viewer2D:: this->layers[4]->PaintGL
1281: invalid value
OpenPSTD-gui: /home/lucasw/own/github/sound/build_openPSTD/eigen/eigen/Eigen/src/Core/CwiseNullaryOp.h:63: Eigen::CwiseNullaryOp<NullaryOp, MatrixType>::CwiseNullaryOp(Eigen::CwiseNullaryOp<NullaryOp, MatrixType>::Index, Eigen::CwiseNullaryOp<NullaryOp, MatrixType>::Index, const NullaryOp&) [with NullaryOp = Eigen::internal::scalar_constant_op<float>; PlainObjectType = Eigen::Array<float, -1, -1>; Eigen::CwiseNullaryOp<NullaryOp, MatrixType>::Index = long int]: Assertion `nbRows >= 0 && (RowsAtCompileTime == Dynamic || RowsAtCompileTime == nbRows) && nbCols >= 0 && (ColsAtCompileTime == Dynamic || ColsAtCompileTime == nbCols)' failed.

Try the openDG fork.

OpenDG (OpenPSTD 2.0 fork)

$ cmake ../openPSTD/ -DEIGEN_INCLUDE=/usr/include/eigen3 -DHDF5_INCLUDE=/usr/include/hdf5/serial -DHDF5_LIBRARY=/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5.so -DHDF5_HL_LIBRARY=/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5_hl.so  -DFFTWF_LIBRARY=/usr/lib/x86_64-linux-gnu/libfftw3f.so

The eigen error is fixed there either, so use eigen 3.2.6

cmake ../openDG/ -DEIGEN_INCLUDE=../eigen -DHDF5_INCLUDE=/usr/include/hdf5/serial -DHDF5_LIBRARY=/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5.so -DHDF5_HL_LIBRARY=/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5_hl.so  -DFFTWF_LIBRARY=/usr/lib/x86_64-linux-gnu/libfftw3f.s

It also crashes if any domains are added to the room.
