Construct a temporal rigid geometry from a reference geometry and a temporal pose

trgeometry(geometry, tpose) → trgeometry

SELECT asText(trgeometry(
  geometry 'Polygon((0 0,1 0,1 1,0 1,0 0))',
  tpose 'Pose(Point(0 0), 0.0)@2001-01-01'));
-- POLYGON((0 0,1 0,1 1,0 1,0 0));Pose(POINT(0 0),0)@2001-01-01

Both arguments must share the same SRID. The reference geometry may be a polygon or a polyhedral surface; the pose may be of any temporal subtype.

Append a single instant to an existing trgeometry, growing the underlying pose path

appendInstant(trgeometry, trgeometry [, maxdist float [, maxt interval]]) → trgeometry

SELECT appendInstant(
  trgeometry 'Polygon((0 0,1 0,1 1,0 1,0 0));[Pose(Point(0 0), 0.0)@2001-01-01]',
  trgeometry 'Polygon((0 0,1 0,1 1,0 1,0 0));Pose(Point(5 0), 0.0)@2001-01-02');

Append an entire sequence to an existing trgeometry

appendSequence(trgeometry, trgeometry) → trgeometry

SELECT asText(appendSequence(trgeometry 'Polygon((0 0,1 0,1 1,0 1,0 0));
  [Pose(Point(0 0), 0.0)@2001-01-01, Pose(Point(10 0), 0.0)@2001-01-02]',
  trgeometry 'Polygon((0 0,1 0,1 1,0 1,0 0));
  [Pose(Point(20 0), 0.0)@2001-01-03, Pose(Point(30 0), 0.0)@2001-01-04]'));
-- POLYGON((0 0,1 0,1 1,0 1,0 0));
-- {[Pose(POINT(0 0),0)@2001-01-01, Pose(POINT(10 0),0)@2001-01-02],
--   [Pose(POINT(20 0),0)@2001-01-03, Pose(POINT(30 0),0)@2001-01-04]}
