Detailed Description

Subclass of GeomOp that supports a ShaderOp input and local transform for ease of object setup.

Connection to legacy 'Material' class is not allowed, although connection to Iops for simple textures is.

Do not use this class if there is not at least 1 input for the merge source (ie input 0)! If your class does not need a merge input or material input then subclass directly from GeomOp instead.

Member Function Documentation

virtual int DD::Image::SourceGeomOp::materialInput ( ) const
inlinevirtual

Return the node input to use for the material binding. Default is the optional_input() which is normally the last input, or (maximum_inputs() - 1).

Referenced by default_input(), DD::Image::SourceGeomOp::SourceEngine::editComposedStage(), input_label(), DD::Image::SourceGeomOp::SourceEngine::processScenegraph(), and test_input().

int DD::Image::SourceGeomOp::minimum_inputs ( ) const
inlineoverridevirtual

Default is 2: merge input and material input(optional). Subclasses that add additional inputs should keep the merge input at 0 and add inputs starting at 1, taking into account the material input will be last.

Do not use this class if the subclass will not support merge input 0!

Reimplemented from DD::Image::GeomOp.

int DD::Image::SourceGeomOp::maximum_inputs ( ) const
inlineoverridevirtual

Default is 2: merge input and material input(optional). Subclasses that add additional inputs should keep the merge input at 0 and add inputs starting at 1, taking into account the material input will be last.

Do not use this class if the subclass will not support merge input 0!

Reimplemented from DD::Image::GeomOp.

int DD::Image::SourceGeomOp::optional_input ( ) const
inlineoverridevirtual

Material input is always the last input index, which is (maximum_inputs() - 1), and draws as a stub arrow on the right side of the node. Note - the minimum and maximum input counts must include this optional input in their totals, otherwise the arrow will not appear on the node.

Do not use this class if the subclass will not support merge input 0!

Reimplemented from DD::Image::Op.

bool SourceGeomOp::test_input ( int  node_input,
Op op 
) const
overridevirtual

Allow ShaderOp or Iop only for eMaterialInput. Connection to legacy 'Material' class is not allowed!

Reimplemented from DD::Image::GeomOp.

References DD::Image::Op::iop(), materialInput(), and mergeInput().

Op * SourceGeomOp::default_input ( int  node_input) const
overridevirtual

Disconnected eMaterialInput is assigned a black default constant ShaderOp, matching legacy behavior.

Reimplemented from DD::Image::GeomOp.

References DD::Image::Iop::default_input(), DD::Image::GeomOp::default_input(), materialInput(), and DD::Image::Op::outputContext().

void SourceGeomOp::knobs ( Knob_Callback  f)
overridevirtual

Calls the GeomOp base class with is_source_geo=true so that the display knobs are correct for a Source object, then calls addSourceKnobs() to let a subclass add it's own knobs.

Reimplemented from DD::Image::GeomOp.

virtual void DD::Image::SourceGeomOp::addSourceKnobs ( Knob_Callback  f)

Knob * SourceGeomOp::makeTransformKnob ( Knob_Callback  f)
protectedvirtual

Make an Axis_Knob called "transform" which will drive the local transform. Calling this will cause a parent Xform prim containing the tranform before createPrims is called. Plugins can implement their own implementation of this to support custom transform knobs.

fdk::Mat4d SourceGeomOp::handlesParentTransform ( DD::Image::ViewerContext ctx)
protectedvirtual

Return the parent transformation for the handles.

The parent transformation is a part of the transformation of the target prim that in the transformation order comes before the actual transformation produced by the Axis_Knob. Depending on the value of the transformation operation order knob, when Prepend, the parent transformation is the concatenated transformation of the parents of the target prim, or when Append, it's the concatenated transformation of the parents and the local transformation of the target prim.

This is called in build_handles() when the handles are building.

Reimplemented from DD::Image::GeomOp.
