Detailed Description

Converts elements of a VTK scene graph into vtk-js elements.

vtkVtkJSSceneGraphSerializer accepts nodes and their renderables from a scene graph and a) composes the elements' data and topology into a Json data structure and b) correlates unique identifiers for data objects in the Json data structure to the data objects themselves. It is designed to operate with vtkVtkJSViewNodeFactory, which handles the logic for scene graph traversal.

When constructing the Json description for a single scene graph node and its renderable, the Add(node, renderable) step processes the renderable into its corresponding vtk-js form. For many renderables this is a no-op, but current restrictions in vtk-js (such as the lack of support for composite mappers and the requirement for data conversion to vtkPolyData) require a nontrival conversion step for certain renderable types. The subsequent ToJson(renderable) is a straightforward conversion of the renderable's data members into a vtk-js Json format.
