Detailed Description

A module for running the Sweep-Line algorithm.

Modified for use laying out grid patterns of rebar inside polygons in the XY plane.

Function Documentation

def concrete.SweepLine.check_for_common_point

(

args

)

 check_for_common_point(args)

def concrete.SweepLine.checkForIntersect

(

args

)

 Make sure rebar line intersects with base line
 
 @param sweep_line rebar line
 @param compareLine base line

def concrete.SweepLine.couplesGenerator

(

args

)

 couplesGenerator(args)

def concrete.SweepLine.ExplicitSweepLines

(

args

)

 A sweepline algorithm that allows the caller to provide
 explicit line to be checked for intersection.
 
 @param poly_list a Polygon.PolyList object
 @param sweepLines an iterable (not a dict) of LineSegment objects
 @param cover the cover for the concrete object
 @param flip add consideration for overlap violating cover
 @param single_piece a boolean that indicates that the rebar piece
                     will be going around a corner and neds to be a single
                     piece. this means that the cover will not be respected 
                     at the corner so that the layouts can be merged after.
 
 @return a list of SmartRebarLayout objects

def concrete.SweepLine.frange

(

args

)

 frange(args)

def concrete.SweepLine.lineSegmentsGenerator

(

args

)

 lineSegmentsGenerator(args)

def concrete.SweepLine.Magnitude

(

arg1

)

Returns

Instance of type float

     Magnitude == Length
 
     C++ signature :
         double Magnitude(Point3D)

def concrete.SweepLine.scrubPoint

(

args

)

 clean up extremely small values by setting them to 0
 
 e.g.
 
 P3D(7.2345e-17, 0., 1200) becomes P3D(0., 0., 1200)

def concrete.SweepLine.SweepLine

(

args

)

 The Sweep-Line algorithm
 
 @param poly_list List of intersections of the concrete polyhedron
                  with the grid plane
 
 @param poly_xform the xform associated with poly_list
 
 @param distanceBetweenRebar The distance between rebar
 
 @param sweep_length The distance needed to cover the whole
                     polyhedron when traversing the sweep_line_path
 
 @param sweep_path A unit vector indicating the path the sweep
                   line should take
 
 @param sweep_dir A unit vector indicating the angle of the
                  rebar
 
 @param cover The distance from the edge of the polyhedron for the rebar
 
 @return a list of Proxie.Layout3D objects representing rebar segments
 
 @note this function expects the line segments to be instances of the
       LineSegment class. See plugins/ConcretePad/LineSegment.py
