This new module provides access to a geometry function.

def 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.
|
|
@type polylines: List of lists containing vectors, each representing a closed polyline.
|
|
@rtype: list
|
|
@return: a list if tuples each a tuple of 3 ints representing a triangle indexing the points given.
|
|
@note: 2D Vectors will have an assumed Z axis of zero, 4D Vectors W axis is ignored.
|
|
@note: 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.
|

I{B{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()
