Dyna_point
geometric-functions dyna_point
syntax
- dyna_point(startpoint, endpoint, distance)
- dyna_point_with_ends(startpoint, endpoint, distance)
definition
-
dyna_point(startpoint, endpoint, distance) results in a new domain-unit, with three generated [[subitems subitem] (see description) :
- Point: the generated point data items
- SequenceNr: the relation between each point and it’s segment.
- Ordinal: the order of the points in each segment.
The dyna_point function results in a set of entries with the points generated by the dyna_point function.
Points are generated at segments, configured by the startpoint and nextpoint data items. In the figure above the light green lines are the segments, the dark green dots the dyna_points.
The distance between the points is configured with the distance parameter or literal.
The dyna_point_with_ends functions like the dyna_point function, only the end coordinates are always added to the resulting attributes.
applies to
- startpoint and endpoint data items with fpoint or dpoint value-type
- literal or parameter dist with float32 or float64 value type
conditions
The domain unit and values-unit of the startpoint and endpoint arguments must match.
