Unity 球状にグリッドをつくる 2

放射線が光り輝きすぎるので

放射はやめて、緯線と経線を引いてみた
･･･といっても、円にするのが大変なので六角形だけど・・・

南北に30°ずつ、東西は60度ずつポイントを置く

緯度別に6個ずつ経度の異なるポイントを置いて、まず緯線を書く。
緯線をつくるpointの配列位置が同じobject同士を繋いで経線を書く。
最後に南北60°のpointと南極、北極をつなぐ。
CSVファイルは多いし、コードの重複感も否めないが、
とりあえずいったんこれで良しとする。

サイズを変えて、同心球（丸くないけど）を三段階

さ、deployしてサイトを更新しよう！
