Detailed Description

The type for missing parent prims we create.

The plugin author must at least implement the createPrims() method.

Member Function Documentation

createPrims()

virtual void DD::Image::SourceGeomOp::SourceEngine::createPrims ( usg::GeomSceneContext &  context, const usg::Path &  path  )

protectedpure virtual

Subclasses implement this to create primitives. context is the scene context path is the suggested path for the new prims.
