ddg.datastructures.halfedge.grid module
- ddg.datastructures.halfedge.grid.get_coordinate_polylines(hed)[source]
Finds parallel coordinate lines in a grid-like half-edge data structure with quadrilateral faces.
- Parameters:
- hedhalf-edge data structure
- Returns:
- x_lines, y_linesdeque , deque
Consists of deques consisting of half-edges representing the polylines. Each polyline is only represented by one chain of half-edges with fixed direction
Notes
The y-direction ist given by v0.edge where v0 ist the first vertex of hed.verts.
