https://github.com/ocornut/imgui

https://github.com/lucasw/imgui_ros supersedes most of this.

The sdl opengl2 and 3 examples take up 400% cpu when run normally, but give these errors:

libGL error: failed to open drm device: Permission denied
libGL error: failed to load driver: i965

Now doing all gephex development in https://github.com/lucasw/gephex, that supersedes everything below.

git clone https://github.com/ChristianFrisson/gephex.git
cd gephex 
./bootstrap.sh
cd ..
mkdir
../gephex/configure --prefix=$HOME/other/install --with-qt-libdir=/usr/share/qt4/lib --with-qt-bindir=/usr/share/qt4/bin --with-qt-incdir=/usr/share/qt4/include

ROS2 - October 2018 - March 2019

There and back again

Started using ROS2 toward end of bouncy release, upgraded to crystal shortly after release, now have returned to ros1.

Maybe will try again when Dashing is release (June 2019?), or will wait for certain key features (some of these maybe already have been achieved, or were already achieved when I was using it but the right way wasn't clear to me):

• ros2 topic echo /image_raw shouldn't take 100% cpu, rqt_image_view shouldn't take 50% cpu. This may be fixed with https://github.com/ros2/rosidl_python/pull/ 35
• ros2 node info should handle namespaces

Visualize the data as a point cloud?

The files look to be mainly csv files.

http://cdn.gea.esac.esa.int/Gaia/gdr2/gaia_source/csv/ has many files.
