class_docstr: TriSurface represents a set of coordinates in 3D space which
  define a surface via a triangulation algorithm (usually Delauney
  triangulation). They key dimensions of a TriSurface define the
  position of each point along the x-, y- and z-axes, while value
  dimensions can provide additional information about each point.
