HUD

The goal of HUD, is to be able to extremely quickly put together a graphical interface. It is built on bgfx, and therefore supports many rendering backends, including OpenGL, Metal and Vulkan.

It can be used either directly through the C++ interface or through the Python bindings.

It built around views. Currently supported views are:

  • ImagePane - shows an image.
  • PointLayer - renders points in 2D.
  • ZStack - Stacks views on top of each other.
  • HStack - Stacks views horizontally.

Views are rendered by hud.AppWindow. It is easy to key handlers to the window using .add_key_handler to respond to key events.

Click handlers can be attached to views to do something when the user clicks the view.

Installing python bindings

sudo apt-get install libglfw3-dev libeigen3-dev

git submodule update --init --recursive
mkdir build && cd build &&
cmake .. -DCMAKE_BUILD_TYPE=Release &&
make -j4

Install bindings with pip install ..

Examples

The example examples/python/stereo_image.py shows a small example which uses the HStack, ImagePane, ZStack and PointLayer views.

Run it with python examples/python/stereo_image.py.
