This section describes the geometry loaders in Cornerstone Core.
If you read the Segmentation rendering section you can see that a Segmentation can be rendered as a Volume (Labelmap), or it can be rendered as a Contour, or Surface (not implemented yet).
Geometry loaders are used to load geometry data from a file or URL in general. Currently,
we only support loading and caching the Contour geometry using the
createAndCacheGeometry (which accepts only the data, so no loading yet) however, additional loaders such as XML, JSON, OBJ, STL, PLY, etc. can be added in the future so that the geometry data can be loaded in different formats.
