前回の クラスタリングの定番アルゴリズム「K-means法」をビジュアライズしてみた が好評だったので、３Ｄ空間でも K平均法をビジュアライズしてみました。ちょっと重めなのでクリックすると始まります。さらにクリックして、１ステップずつ動かしてみてください。3次元にしてみると、宇宙空間のように見えてきて美しいです。前回からは数式の上ではほとんど変わってなくて、２次元空間上での距離だったのが３次元での距離になったぐらいです。K平均法については、前回のエントリ クラスタリングの定番アルゴリズム「K-means法」をビジュアライズしてみた をご覧ください。ちなみに、3次元座標の計算は、Flash 10 から導入された Matrix3D を使っています。ソースは [as]FP10をそろそろ。Matrix3Dとか [NUTSU] を参考にさせてもらいました。Zソートしてないので、たまに奥のものが手前に

Sprite.jsはJavaScript製のオープンソース・ソフトウェア。JavaScriptを使ってゲームを作る場合、キャラクターの描画には二種類の方法が考えられるだろう。一つは画像を使う方法、もう一つはドット単位やCanvasを使って直接描画する方法だ。 32体の人形が歩き回るデモ 後者はあまりに面倒だ。だから大抵画像を使った方法を選択するはずだ。そんな時、歩いたりジャンプしたりするアクションごとに画像が分かれていると、予め読み込んでおくデータ数が増えてしまう。それを解決するのがSprite.jsだ。 Sprite.jsがユニークなのは、一枚の画像を使って一つのキャラクターを表現する所にある。つまりGoogleなどがよく使っている小さなアイコン画像を固めて一つの画像ファイルにし、CSSを使って表示場所を切り替えて描画するSpriteをアニメーションに使っているのだ。 キー入力で動くデモ

SVGスプライトをつくってみよう1
SVGの最も有用な使用法の一つ、「複数のベクターグラフィックを一つのデータにまとめて、使いたい時に呼び出す」という「SVGスプライト」があります。 「SVGを使おう！」でもほんの少しお話ししましたが、cssスプライトとの大きな違いとしては、やはり「スタイルを都度変更できる」ところでしょう。 カラーバリエーションやサイズバリエーション、ちょっとした違いごとに同じグラフィックをいくつも作成する必要が無くなります。また、ベクターグラフィックなのでサイズを気にする必要もまったくありません。 極端に言えば、10×10pxのSVGを1000×1000pxに引き延ばそうが何ら問題はないのです。（※画像と同様 描画は重くなりますけれど・・） 今回はこの「SVGスプライトのつくり方」として、基礎となる部分をお話しさせていただきます。 この部分をしっかり理解しておくとIllustratorなどからSVGスプラ
