# The exporter will behave as any other ParaView exporter (VRML, X3D, POV...)
# but will generate several types of files. The main one is the scene graph
# description define as a JSON object with all the corresponding binary+base64
# pieces that come along with it. But also with it come a single standalone HTML
# file that can directly be used to see the data in a browser without any plugin.
#
# This code base should be cleaned up to follow VTK standard and even be
# integrated into VTK itself. But for now it is provided as is.
