Spinfade 2
So here comes the second version with 3D animation. You must have wondered why I call it Spinfade if you've only seen the initial version; but you'll understand here - it spins and letters fade in, thus it is Spinfade! Ha ha. Planning to make messages fade into one another.
第二弾！３次元での表現は相変わらず素晴らしいねー。いつも７５０を３次元の変形指数（物体が近づく、遠くへいったりするときにどれだけ変形するか。１の変形が最大、無限大「∞」の変形が最少）にしていたのですが、今回は変形が大きすぎて、メッセージを描く小さい四角の間に隙間ができてしまったりしたので、思い切って２０００にしました。次回は、メッセージが次のメッセージへと、形が変わるようにします。
