This extension allows to display graphical representation of variables during debugging.
Currently it supports Boost.Geometry and Boost.Polygon models, Boost.Variant, STL/Boost containers of values and points as well as C-style arrays. The extension has the following components:
- Debugger visualizers for Boost.Array, Boost.Container, Boost.Geometry, Boost.MPL, Boost.Polygon, Boost.Tuple and Boost.Variant
- Geometry Watch tool window displaying geometries in a common coordinate system, e.g. Boost.Geometry or Boost.Polygon polygons
- Graphical Watch tool window displaying graphical representation of variables, e.g. Boost.Geometry models or vectors of values
- Plot Watch tool window displaying plot representation of variables, e.g. vector of doubles
Feel free to report bugs, propose features and create pull requests. Any help is appreciated.
You can download this extension from Visual Studio Gallery.
You may contact me at Boost.Geometry mailing list.
You need Microsoft Visual Studio 2015 Update 3, .NET Framework 4.5.2 and Visual Studio 2015 SDK.
To install after building double-click the *.vsix file from bin/Debug or bin/Relase directory.
This extension works with Visual Studio 2013, 2015 and 2017.
- place a breakpoint somewhere in the code
- start debugging
- after a breakpoint hit enable the tool window from the menu

Geometries in spherical_equatorial and geographic coordinate systems are displayed in a way allowing to see what coordinates were used to define a geometry. Note that various libraries may require coordinates in a certain range. This extension tries to display any coordinates as good as possible.
Segments may be densified in order to reflect the curvature of the globe. This behavior is enabled by default but can be disabled in Tools->Options->Graphical Debugging->Geometry Watch.

Geometries in spherical_equatorial and geographic coordinate systems are displayed in a convenient, compact way.
Segments may be densified in order to reflect the curvature of the globe. This behavior is enabled by default but can be disabled in Tools->Options->Graphical Debugging->Graphical Watch.

Watch window displaying plot representation of variables in a single image. Type of plot can be set in Options.
Supported containers of values convertible to double and containers of points:
- C-style array
- Pointer to elements with size specifier e.g.:
ptr,5
- STL: array, vector, deque, list
- Boost.Array: array
- Boost.Container: vector, static_vector
where points can be of any supported point type (coordinate system is ignored):
- STL: complex, pair
- Boost.Geometry: point, point_xy
- Boost.Polygon: point_data
Geometry Watch and Plot Watch has zooming/cropping feature.
Options for each Watch can be found under Tools->Options->Graphical Debugging
The extension attempts to obtain data through direct memory access if possible. From this feature benefit all supported containers of fundamental numeric types and geometries using such coordinate types. E.g.:
int arr[5]
std::array<float, 5>
std::vector<double>
std::deque<std::pair<float> >
std::list<std::complex<double> >
boost::container::vector<int>
boost::geometry::model::linestring< boost::geometry::model::point<double, 2, boost::geometry::cs::cartesian> >
boost::polygon::polygon_data<int>
- etc.
This behavior is enabled by default but can be disabled in options under Tools->Options->Graphical Debugging->General
The extension supports Visual Studio themes. The visualization of variables may be drawn in two versions, dark or light depending on the brightness of the theme background color.
