PolyFill(polylines)
Takes a list of polylines and calculates triangles that would fill
in the polylines. Multiple lines can be used to make holes inside a
polyline, or fill in 2 seperate lines at once.
-
- Parameters:
polylines
(type=List of lists containing vectors, each representing a
closed polyline.)
- Returns:
-
a list if tuples each a tuple of 3 ints representing a
triangle indexing the points given.
(type=list)
Notes:
- 2D Vectors will have an assumed Z axis of zero, 4D Vectors W axis is
ignored.
The order of points in a polyline effect the direction returned
triangles face, reverse the order of a polyline to flip the normal of
returned faces.
Example:
The example below creates 2 polylines and fills them in with faces,
then makes a mesh in the current scene:
import Blender
Vector= Blender.Mathutils.Vector
# Outline of 5 points
polyline1= [Vector(-2.0, 1.0, 1.0), Vector(-1.0, 2.0, 1.0), Vector(1.0, 2.0, 1.0), Vector(1.0, -1.0, 1.0), Vector(-1.0, -1.0, 1.0)]
polyline2= [Vector(-1, 1, 1.0), Vector(0, 1, 1.0), Vector(0, 0, 1.0), Vector(-1.0, 0.0, 1.0)]
fill= Blender.Geometry.PolyFill([polyline1, polyline2])
# Make a new mesh and add the truangles into it
me= Blender.Mesh.New()
me.verts.extend(polyline1)
me.verts.extend(polyline2)
me.faces.extend(fill) # Add the faces, they reference the verts in polyline 1 and 2
ob= Blender.Object.New('Mesh')
ob.link(me)
scn = Blender.Scene.GetCurrent()
scn.link(ob)
Blender.Redraw()
