Determines the type of orientation as a combination of standard DX/DY/DZ directions. This enumeration defines a model orientation looking towards the user's eye, which is an opposition to Camera main direction. For example, V3d_Xneg defines +X Camera main direction.
This enumeration defines only main Camera direction, so that the Camera up direction should be defined elsewhere for unambiguous Camera definition. Open CASCADE does not force application using specific coordinate system, although Draw Harness and samples define +Z-up +Y-forward coordinate system for camera view manipulation. Therefore, this enumeration also defines V3d_TypeOfOrientation_Zup_* aliases defining front/back/left/top camera orientations for +Z-up convention as well as V3d_TypeOfOrientation_Yup_* aliases for another commonly used in other systems +Y-up convention. Applications using other coordinate system can define their own enumeration, when found suitable.
