Overview

   This factory creates a feature with a point cloud of the specified size with
   general values using the parameters supplied.

   The number of points in the created point cloud is defined based on the
   SIZE_SPEC parameter. If EXTENTS is specified, then the points in the cloud
   are defined by X_LL, Y_LL, X_UR, Y_UR, AVERAGE_X_SPACE, and AVERAGE_Y_SPACE.
   If ORIGINSIZE is specified, then the points int he cloud are defined by
   WIDTH, HEIGHT, X_LL, Y_LL, AVERAGE_X_SPACE, and AVERAGE_Y_SPACE.

   The X_COMPONENT_TYPE, Y_COMPONENT_TYPE, and Z_COMPONENT_TYPE parameters
   may be used to specify the type of the x, y, and z components.
   When an integer type is specified, the component values will be simple
   ascending integers (e.g. 0, 1, 2, ...), and the component will have a scale
   and offset value specified by other keywords (e.g. AVG_X_SPACE and X_LL).
   When a floating point type is specified, the component values will be
   multiplied out (e.g. X_LL, X_LL + 1*AVG_X_SPACE, X_LL + 2*AVG_X_SPACE, etc.).

   The ROTATION parameter specifies how to rotate the point cloud after it is
   generated.

   As points are generated, they are given Z values based on the Z_PATTERN
   parameter. The Z values will be assigned as follows:

      SINGLEVALUE - every point in the cloud will have a z value specified by
      MIN_Z

      CHECKERPATTERN - the points will have z values between MIN_Z and MAX_Z
      arranged in a gradient throughout the point cloud.

      TRIG - the points will have z values between MIN_X and MAX_Z arranged in a
      trigonometric pattern through the point cloud.

      NONE - the points will not have z values.

   As points are generated, they will receive the point components specified by
   POINT_MEASURES. Values for the components are generated as follows:

      Angle, Classification, Color, Intensity, Returns- will be assigned values
      between their min/max parameters as defined by the VALUE_PATTERN
      parameter. The minimum for returns is 1. If the VALUE_PATTERN is
      SINGLEVALUE, the component will have a value specified by its minimum.
      If the VALUE_PATTERN is CHECKERPATTERN, the component will have values
      arranged in a gradient throughout the point cloud. If the VALUE_PATTERN is
      CHECKERBOARD, the component will have values alternating between its
      min/max.

      Flight Line - starts at 1 and increases as specified by the
      ROWS_PER_FLIGHTLINE parameter

      Flight Line Edge - will be 0 or 1 depending on if this is the last or
      first row with a particular flight line value

      GPS Time, Posix Time - will start at START_TIME and increase based on
      TIME_INCR parameter

      GPS Week - will start at MIN_GPS_WEEK and increase in a gradient pattern
      through the point cloud with the last point having a value of MAX_GPS_WEEK

      Number Of Returns - will have the value specified by MAX_RETURN_NUM

      Point Id - a unique number assigned by the system

      Scan Direction - will be 0 or 1 depending on the current value of the
      flight line

   The COMPONENT_LIST keyword may be used to generically specify additional
   components. The format of this keyword is
      [<component name>,<component type>,<min value>,<max value>]+
   All components will be assigned values based on VALUE_PATTERN.
   Note that for string components, CHECKERPATTERN will be treated as
   CHECKERBOARD.
