Orbbec Unity Sample

preview gif


  • Windows machine
  • Orbbec Astra
  • Unity 2019.2.9f1 (could work for others, but only tested with this)
  • Visual Studio 2019 (could work for others, but only tested with this)


  • Depth stream visualiser
  • Colour stream visualiser
  • Body tracking (joints only). If you stand far back enough, spheres will appear representing joints
  • VFX Graph example using both depth and colour

Known issues

  • Free body tracking will only work until March 21 2020
  • If you have your own licence, add it in AstraController.cs
  • Colour and depth streams are misaligned, currently Orbbec SDK’s depth registration does not help much
  • ColourToTexture and DepthToTexture implementations could be improved. Currently data type mismatches and lack of read/writable option for RenderTextures created in the UI makes the implementation sub-optimal.
