Imath::M44f transform()
Returns the transform for the procedural.
Definition: ProceduralHolder.h:49
const char * node_shape() const
Implemented to distinguish these nodes from others.
virtual void build_handles(DD::Image::ViewerContext *ctx)
Implemented to draw the procedural.
The IECoreNuke namespace holds all the functionality of libIECoreNuke.
Definition: BoolParameterHandler.h:40
IECore::ConstParameterisedProceduralPtr procedural()
Returns the procedural which is being held.
IECoreGL::ConstScenePtr scene()
