Hi,
Some thinking about opencv and 3D engine.
Before 3.3 opencv uses as 3D api OpenGL or DirectX and 3D engine Vtk in Viz module. Now in the opencv_contrib OGRE 3D engine is available in OVIS module. Opencv team thinks about a better support for data sets: Deal with Unity or Unreal (2017-11-13). I use openscenegraph in the opencv program. I wonder if I should go on with openscenegraph or may be changed to a new 3D engine for a better compatibility with opencv.
Suggestions about 3d engine in opencv are welcome.
