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

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

inline

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

Referenced by DD::Image::operator<<().

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.

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)

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.

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.

const GeomOpEngine::OpInputTimeMap & GeomOpEngine::InputBinding::opsForView

(

int32_t

view

)

const

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