Detailed Description

Provides the transformable scene Op standard transform knobs with prim edit functionality. This interface is only intended to be attached to AxisOp subclasses and there are a number of assumptions to that effect, such as the getAxisOp() method.

This interface contains a local transform matrix and an optional local-parent transform matrix which are normally filled in by Knobs. The local-parent enables an arbitrary parenting hierarchy to be decomposed and contained within the AxisOp subclass allowing the node to be disconnected or disassociated from a parenting network or scenegraph. The node is thus effectively localized and can be copied, pasted into other scripts, etc.

Member Function Documentation

◆ getAxisOp()

virtual AxisOp * DD::Image::SceneOpI::getAxisOp ( )

pure virtual

Return the AxisOp subclass the interface is attached to. Should return 'this'. This can be further cast to an AxisSceneOp (or CameraSceneOp/LightSceneOp) using 'op_cast()' like so: 'AxisSceneOp* axisSceneOp = op_cast<AxisSceneOp*>(getAxisOp())'. Must implement.

Implemented in DD::Image::AxisSceneOp, DD::Image::CameraSceneOp, and DD::Image::LightSceneOp.

Referenced by _createParentPrims(), _getLocalParentTransformAnimation(), _getLocalTransformAnimation(), _getSceneOpInputParentTransformAt(), _getSceneOpLocalAxisTransformAt(), _getSceneOpLocalParentAxisTransformAt(), _getSceneOpTransformComponentsAt(), _getSceneOpWorldTransformAt(), _sceneOpKnobChanged(), _validateTransforms(), _writeTransformOps(), addConstrainOptionsKnobs(), addTransformKnobs(), asAxisSceneOp(), asCameraSceneOp(), asLightSceneOp(), buildBasePrimPath(), geometryComposeState(), geometryEditVersionState(), geometryStateVaries(), opKnob(), setReadOnlyLocalParent(), writeInputOpAsAssetPath(), and writeKnob().

◆ sceneInput()

virtual int32_t DD::Image::SceneOpI::sceneInput ( ) const

inlinevirtual

Return the node input to use for the scene source, usually a GeomOp. -1 indicates an internal scene source with no input connection. Default implementation returns -1.

Reimplemented in DD::Image::AxisSceneOp, DD::Image::CameraSceneOp, and DD::Image::LightSceneOp.

◆ sceneInputOp()

virtual GeomOp * DD::Image::SceneOpI::sceneInputOp ( ) const

inlinevirtual

Return the sceneInput() input cast to a GeomOp, if possible. Default returns null.

Reimplemented in DD::Image::AxisSceneOp, DD::Image::CameraSceneOp, and DD::Image::LightSceneOp.

◆ parentInputSceneOp()

virtual SceneOpI * DD::Image::SceneOpI::parentInputSceneOp ( ) const

inlinevirtual

Return the AxisOp::parentInput() input cast to a SceneOpI, if possible. Default returns null.

Reimplemented in DD::Image::AxisSceneOp, DD::Image::CameraSceneOp, and DD::Image::LightSceneOp.

Referenced by buildBasePrimPath().

◆ constrainInputSceneOp()

virtual SceneOpI * DD::Image::SceneOpI::constrainInputSceneOp ( ) const

inlinevirtual

Return the AxisOp::constrainInput() input cast to a SceneOpI, if possible. Default returns null.

Reimplemented in DD::Image::AxisSceneOp, DD::Image::CameraSceneOp, and DD::Image::LightSceneOp.

◆ primarySchemaType()

virtual const usg::Token & DD::Image::SceneOpI::primarySchemaType ( ) const

pure virtual

Return the name of the primary USD schema this node is handling. For example usg::GeomTokens.types.Camera, or usg::lux::LuxTokens.types.DistantLight. Must implement.

Implemented in DD::Image::AxisSceneOp, DD::Image::CameraSceneOp, and DD::Image::LightSceneOp.

◆ getAppliedApiSchemaTypes()

virtual usg::TokenArray DD::Image::SceneOpI::getAppliedApiSchemaTypes ( ) const

inlinevirtual

Returns a list of additional named schema APIs this node is handling. For example a LightSceneOp would likely apply usg::lux::LuxTokens.types.LightAPI and optionally usg::lux::LuxTokens.types.ShapingAPI.

Default implementation returns an empty array.

Reimplemented in DD::Image::LightSceneOp.

◆ parentPrimCreateType()

virtual const usg::Token & DD::Image::SceneOpI::parentPrimCreateType ( ) const

inlinevirtual

Return the prim type to create for missing prims. Default implementation returns the value of the 'parent_prim_type' knob.

Referenced by _createParentPrims(), and buildBasePrimPath().

◆ buildBasePrimPath()

usg::Path SceneOpI::buildBasePrimPath ( ) const

virtual

Return the full path of the -primary- prim and all its parents created by this node. This is the 'top' prim where any child prims are rooted under.

For example if this is an AxisOp it's typically a single Xform prim, but a CameraOp or LightOp may have additional prims after the main Xform (ie for a stereo camera rig) so this connection point needs to be explicitly identified.

Retrieve the base prim name by calling name() on the returned path.

Base class implementation

Reimplemented in DD::Image::AxisSceneOp, DD::Image::CameraSceneOp, and DD::Image::LightSceneOp.

inlinevirtual

Return the default filter string to apply in the prim path knob. Default is a filter for Xforms.

Reimplemented in DD::Image::AxisSceneOp, DD::Image::CameraSceneOp, and DD::Image::LightSceneOp.

◆ transformCache()

const AxisValsSet * DD::Image::SceneOpI::transformCache ( ) const

GeometryProviderI: Return true if the AxisOp this is attached to should provide geometry for the given purpose. SceneOps usually do not generate renderable geometry like meshes, so by default if purpose is usg::GeomTokens.overlay then return true, otherwise false.

Reimplemented from DD::Image::GeometryProviderI.

◆ buildGeometryStage()

void SceneOpI::buildGeometryStage	(	usg::StageRef &	stage,
		const usg::ArgSet &	requestArgs = `{}`,
		const fdk::TimeValueSet &	sampleTimes = `fdk::TimeValueSet()`
	)

overridevirtual

GeometryProviderI: Provide the cached exported stage. The cached stage is only created when this method is called. If the cached stage has the same composeState as the exporter then buildGeometryLayer() is called with any additional sample times but the cached stage itself is left untouched. stage is then set to the exporter's cached stage.

Reimplemented from DD::Image::GeometryProviderI.

◆ writeScenePrimsToLayer()

void SceneOpI::writeScenePrimsToLayer	(	usg::LayerRef &	layer,
		bool	appendTo,
		const fdk::FrameValueSet &	times
	)

Write prims this SceneOp generates to an external layer, ignoring the SceneOp's state.

This method is assumed to be called from a separate object which owns the Layer and is handling the allocation and clearing of the layer & clearing any attributes.

layer is assumed to have been created, configured and valid. The list of sample times is a request to the SceneOp and is not guaranteed to result in those exact time samples in the output layer. For example a Knob may not be animated and will only set the default sample, or the keyframes being output are sparse.

◆ _createAuthoringProvider()

AuthoringProvider * SceneOpI::_createAuthoringProvider	(	Knob *	k,
		uint64_t	componentId
	)

protectedvirtual

Subclass implementation of SetValueProvider to create the correct AuthoringProvider subclass and store in the SceneOpNode. Default implementation creates an AxisValsProvider.

Reimplemented in DD::Image::CameraSceneOp, and DD::Image::LightSceneOp.

Referenced by DD::Image::CameraSceneOp::_createAuthoringProvider(), DD::Image::LightSceneOp::_createAuthoringProvider(), and SetAuthoringProvider().

◆ buildSourceSceneState()

virtual fdk::Hash DD::Image::SceneOpI::buildSourceSceneState ( const fdk::Hash & hash )

inlineprotectedvirtual

Called by SceneOpNode when determining the global source scene state hash. Subclasses can implement this to take any additional values into consideration when determining extractor state, like local knob values, but must careful not to include possibly animating values like Op::hash().

Note that is assumed to be called on the firstOp() and not any specific OutputContext, so all Knob value queries should to be done directly on a Knob and must avoid relying on Op::knobs() storing into local Op variables.

This should always be called from the main thread.

Base class does nothing.

Reimplemented in DD::Image::CameraSceneOp.

◆ getExtractKeyRange()

void SceneOpI::getExtractKeyRange	(	SceneOpNodeI::SharedData &	data,
		fdk::TimeValue &	firstKey,
		fdk::TimeValue &	lastKey
	)

protectedvirtual

Retrieve the first/last range of keyframes for all prim attributes that will be extracted from. If there are no keyframes (no animation) then set the first/last keys to fdk::defaultTimeValue(). This special value helps a provider quickly determine there are no animated values and thus speed up value retrievals.

Default implementation retrieves any xform attribute keyframes, or if none sets the first/last keys to fdk::defaultTimeValue().

◆ extractSceneData()

bool SceneOpI::extractSceneData	(	SceneOpNodeI::SharedData &	data,
		const fdk::TimeValueSet &	addlSampleTimes = `fdk::TimeValueSet()`
	)

protectedvirtual

Extract the scene data that needs to be cached or processed for the entire scene range. Usually called by SceneOpNode updateSourceSceneData() when the source scene state changes. This should always be called from the main thread.

Important note: the particular Op instance this method is called on is unimportant as the data created by this method is intended to be shared by all sibling Ops. One random Op instance will be called for each configuration change (a stage, prim path or input change) so avoid storing any local data into this Op instance.

Not all prim data needs to be cached if cheap to retrieve from USD, however a good example of expensive data is extracting and decomposing transform matrices which need to be euler filtered over the entire scene. In these cases it's cheaper to do the processing all at once and cache the result.

Default implementation calls extractSceneXformData() and returns true.

◆ extractSceneXformData()

void SceneOpI::extractSceneXformData	(	SceneOpNodeI::SharedData &	data,
		AxisValsArray &	axisValsSamples,
		bool &	isDefaultXforms,
		const fdk::TimeValueSet &	addlSampleTimes = `fdk::TimeValueSet()`
	)		const

protectedvirtual

Default implementation extracts the transform info by decomposing the parent and local matrices and runs a euler filter to remove flips, caching the resulting data for the PrimValueProviders to later retrieve. This work is only done when the stage contents change, either via recomposition or layer/stage edits.

◆ getXformDataAt()

AxisVals SceneOpI::getXformDataAt	(	SceneOpNodeI::SharedData &	data,
		const OutputContext &	context
	)		const

protectedvirtual

Retrieve the transform data for a single time sample at OutputContext. Assumes that extractSceneData() has already been called to first perform any global scene data processing and any caches are ready to be read from.

Default implementation retrieves the AxisVals from the transform cache and does any required interpolation.

◆ _validateTransforms()

void SceneOpI::_validateTransforms	(	bool	for_real,
		ndk::XformParameters &	outputXformParams
	)

protectedvirtual

Call this from owner (Axis)Op's implementation of Op::_validate() to build the local _xformComponents.localParentAxis, _xformComponents.localAxis and final local transform matrices for the current (Axis)Op's store state.

Default implementation builds _xformComponents.localParentAxis from the local parent TRS knobs. _xformComponents.localAxis has already been built during Knob store by the 'transform' Axis_Knob but a subclass could override that result via _getSceneOpLocalAxisTransform().

The local transform matrices are build by calling _buildLocalTransforms() with the updated individual transform components, then those are used to build the final concatentated output transforms in outputXformParams.

Note that the concatenated world matrices (l2w, w2l) in outputXformParams should not be calculated in this method and should be handled by the caller.

		fdk::Mat4d &	preConstraintXform,
		const ndk::ConstraintMatrixParams &	constraintParams,
		ndk::XformParameters &	finalLocalXforms
	)		const

protectedvirtual

Build the final local transforms from the individual transform components, applying any additional constraints.

By default this is called by _validateTransforms() and _getSceneOpWorldTransformAt() so the same transform calculations are done for both evaluation paths.

Note that the concatenated world matrices (l2w, w2l) in finalLocalXforms should not be calculated in this method and should be handled by the caller.

		int32_t *	nAnimatedExpressions = `nullptr`,
		int32_t	view = `-1`
	)		const

protectedvirtual

Does the local parent transform animate? This is only an indicator that the transform -MAY- vary in time, not that its value actually does. Default implementation returns true if the local parent knobs have animation enabled or if the constraint input Op varies and it is applied to the local parent TRS. If the knob(s) are animated and keyTimes provided then the knob animation keys times are appended to it. If view is > -1 then the times are retrieved from just that view. If any knobs have expressions but no keyframes then this will also return true, and nAnimatedExpressions will be set > 0, if provided.

Mat4d SceneOpI::_getSceneOpWorldTransformAt ( const OutputContext & context ) const

protectedvirtual

Calculate the final world transform at a specific OutputContext.

Note that this does the same transform calculation as _validateTransforms() but samples all knobs and inputs at a different context than the one the AxisOp is at by calling the individual transform component 'At(context)' methods.

protected

Same but controls the default value testing via the ignoreDefaultTest arg.

If ignoreDefaultTest is false we test if the knob is at its default value and only write the knob if it is off default. USD, like Nuke, will use the default value of the knob as fallback if an explicit value is not authored.

However, often the Nuke knob's default will not be the same as the USD property default, and in those cases we always want to author the USD property so that we don't allow USD to use the default fallback. Examples of this are the various CameraOp lens values like focal length, hAperture, vAperture, etc which historically have a default difference to the UsdGeomCamera schema. We don't want to suddenly change Nuke's (arbitrarily chosen) historic camera defaults to conform to USD's (arbitrarily chosen) defaults.

protected

Same but the attribute Value can be filled in from multiple source ArrayKnobs. This is need when multiple source Knobs contribute to one attribute Value. If any of the source knobs are animated then the output attribute will have time samples.

Note - targetPropertyType is required since a specfic type cannot be divined from multiple source knobs.
