ポリラインの文字を作るスクリプト

Blenderでリグ等に文字列を表示する場合に
テキストオブジェクトからメッシュを作成するものの
フォント選んで 文字入力して　変換して　と手順を踏むものの　そんな手間かけるのも煩わしいし
もっとシンプルな見た目の文字が欲しかったので
自分でポリゴンのフォントを作って　文字列のオブジェクトを作成するスクリプトを作ってみた

パブリックドメインのドットフォントを参考に 各文字は1つの繋がったメッシュになるようにした
```py
import bpy
# メッシュを作成する文字列
str = "AbCD4fhjk"

ちなみに文字のメッシュの情報の書き出しはこんな感じ
![image.png](https://qiita-image-store.s3.ap-northeast-1.amazonaws.com/0/151493/bac232b3-e162-63e8-f611-9553aaf11533.png)
選択したオブジェクト名を辞書のキーにするようにメッシュのデータを出力してるだけ
うまく使えば　ファンタジーの独自文字をモデリングしておいて変換表を作れるかも？
```py
import bpy
objects = bpy.context.selected_objects
print("{")
for obj in objects:
    mesh = obj.data
    #頂点座標
    v_data_list = []
    for v in mesh.vertices:
        pos = v.co
        v_data_list.append([pos[0],pos[1]])
    #稜線
    e_data_list = []
    for e in mesh.edges:
        e_data_list.append([e.vertices[0],e.vertices[1]])
    print("\"%s\":(%s, %s)," % ( obj.name, str(v_data_list), str(e_data_list) ))
