ShowOutwardNormals | Cellzilla2D Home |
Description
Generates a graphic for the outward pointing normal unit vectors to the edges of a polygon.
Needs["Cellzilla2D`"];
Return Value
ShowOutwardNormals[{{x1,y1}, {x2,y2}}, dir, flag]
dir is any list of graphics directives
flag if True, prints the polygon; if not, only shows the arrow.
ShowOutwardNormals[Tissue, options] displays the normal vectors to cells and/or edges as specified by the options
Options
"Cells"->{} List of cell numbers; the outward pointing normal vectors will be drawn for each edge of the specified cells, with the styles defined by option "Style".
"Edges"->{} List of edges numbers; opposite normal vectors will be drawn with the styles defined by option "Style" for each edge specified. Since an "outward" direction is undefined in the absence of specific edges, two oppostive vectors are drawn for each edge.
"Style"-> {} - any Graphics option or directive, e.g., Red or Dotted.
