Coordinate System​

BME4 uses a left-handed coordinate system same as Unity3D and Cinema 4D.

  • X+ goes right, Y+ up and Z+ front
  • The order of quaternion is X Y Z W
  • The euler angle uses Y X Z (yaw, pitch, roll) as rotation order and degree as unit
  • Grid length is 1 meter in the sense of modeling softwares
