Detailed Description

Nuke Node input binding. Note that this is NOT an Op input!

If _upstreamEngine is not null the InputBinding is connected to a GeomOp with a GeomOpEngine. _upstreamFirstOp will be a GeomOp, and _upstreamEngine can be called directly.

Otherwise _upstreamFirstOp will be some other Op type and can be type tested.

In both cases _upstreamOpsPerView will contain the list of Ops at the requested OutputContexts.

Member Function Documentation

◆ geomEngine()

GeomOpEngine * DD::Image::GeomOpEngine::InputBinding::geomEngine ( ) const

inline

Returns a GeomOpEngine pointer if the connected input object is another GeomOpEngine (a GeomEngine).

◆ baseOp()

Op * DD::Image::GeomOpEngine::InputBinding::baseOp ( ) const

inline

If the input is an Op type, return its Op::firstOp(), which may not be at any specific desired OutputContext. To get a specific frame/view Op variant use the opAt() and opAtContext() methods.

◆ inputFrameForOpTime()

double GeomOpEngine::InputBinding::inputFrameForOpTime ( double member_geop_frame ) const

Possibly remap the member GeomOp frame to a time-warped input Op frame. Also rounds the frame to three decimal places (ie .001, a thousandth of a frame)

Referenced by DD::Image::GeomOpEngine::inputOpAt().

◆ opAt()

Op * GeomOpEngine::InputBinding::opAt	(	double	frame,
		int32_t	view = `-1`
	)		const

Returns the matching Op input for a specific frame and view, if one exists. The frame number is rounded to three decimal places (ie .001, a thousandth of a frame) to make it more likely that a match will occur, and possibly remapped. If view is non-valid then the 'main' view (view index 1) is used instead.

◆ opAtContext()

Op * GeomOpEngine::InputBinding::opAtContext ( const OutputContext & ctx ) const

Returns the matching Op input for the provided OutputContext (frame & view) if one exists. The OutputContext's frame number is rounded to three decimal places (ie .001, a thousandth of a frame) to make it more likely that a match will occur.

◆ opsForView()

GeomOpEngine::OpInputTimeMap & GeomOpEngine::InputBinding::opsForView ( int32_t view )

Returns the time/InputOp map for a specific view. If the view doesn't exists the map will be empty.
