For debugging rotational tracking, this example is quite handy since it does not render VR graphics, but just visualizes the IMU with 3 axes. I wrote it to debug the VIVE controller IMU. It uses the model matrix patch from @ChristophHaag opengl3 branch and is written in GL3 as well, but is very minimalistic.
It uses the MIT licensed
math_3d.h
header to do the linear algebra required for GL3. This is also on @ChristophHaag's GL3 branch, but I created aext_deps
folder inexamples
, so multiple examples can share it.I added it to meson and CMake. For meson it builds as soon the dependencies are available, for CMake it builds when the SDL examples are enabled.
