nw.jsでデスクトップアプリを作る(17) - SVG pathをthree.js shapeに変換する

公開:2015-03-01 10:29
更新:2017-09-22 05:40
カテゴリ:nw.js,three.js,svg,javascript,webgl,html5,nw.jsでデスクトップアプリを作る

今日ようやくthree.jsで表示することができた。がまだ問題は残っている。

原因はまだわからない。

実装するにあたっては下記のコードを参考&拝借している。

SVG path to Three.js shape

で肝のコードtransformSVGPath()だが、下記コードも参考&拝借している。

three.js/webgl_geometry_extrude_shapes2.html at master · mrdoob/three.js · GitHub

SVG path to Three.js shape」にも含まれている。もともと「asutherland/d3-threeD · GitHub」に含まれているものであったらしい。

変換するとなぜか上下が反転してしまうので変換時にy座標を反転するようにしている。

またしてもこのコードはIEとFirefoxでは動作しない。私のコードのつくりが悪いのだと思うが。

## SVGからthree.jsのshapeへの変換
[エドワード・マイブリッジ](http://upload.wikimedia.org/wikipedia/commons/7/73/The_Horse_in_Motion.jpg)の「Horse in motion」をInkscapeでトレースし、各馬をセル化したものをthree.jsのshapeに変換し表示しています。

見ていただくとわかりますが、Bugが残ってます。あとIEとFirefoxでは動作しません。私のコードが悪いようです。
下記のURLから動くデモが見れます。
