7.2 Points, Lines, and Planes

Topic Version	1	Published	09/11/2015	Topic Change History
For Standard	RESQML v2.0.1

Table 7.2-1 summarizes the different construction types available for the geometry of points, lines, and planes. Changes for this latest version of RESQML include a much richer list of construction types and a simplified (restricted) design that supports only HDF5 for explicit point arrays (previously both XML and HDF5 arrays were supported).

Table 7.2-1 Point, Line and Plane Geometry
Construction Type	Definition/Explanation
Point Geometry
Point3d HDF5 Array	Explicit HDF5 array of N*3 coordinates, (X,Y,Z)
Point2d HDF5 Array	Explicit HDF5 array of N*2 coordinates (X,Y) for a 3D point (X,Y,0)
Point3d ZValue Array	Points extracted from another representation, and then modified to have new Z coordinate values
Point3d Lattice Array	Points in a lattice created from a start point and offset vectors
Point3d From Representation Lattice Array	Points extracted from a representation, using a lattice of indices to space the sampling
Point3d Parametric Array	Points defined parametrically using parametric lines
Line Geometry
Parametric Line Geometry	Parametric line geometries are described in more detail in the next table
Parametric Line From Representation Geometry	Parametric line extracted from a representation
Plane Geometry
Horizontal Plane Geometry	Definition of the infinite geometry of a horizontal plane provided by giving its unique Z value.
Titled Plane Geometry	Used to describe the infinite geometry of a potentially tilted plane from three points.

Point, line, and plane geometry are described in the following figures ( Figure 7.2-1 , Figure 7.2-2 , Figure 7.2-3 ). Each individual construction is also described in the RESQML Technical Reference Guide.
