Structure SynthとSunflowでミラーの立方体を描画する

Structure SynthとSunflowでミラーの立方体を描画するには、以下のスクリプトを実行します。

// 黄色っぽい立方体
{ z 3 y 1 s 2 color #d0c040 } box
// 水色っぽい立方体
{ x -3 y 1 s 2 color #7799ff } box
//ミラーの立方体
{ y 1 s 2 } box::mirror
// 白色の立方体
{ x 3 y 1 s 2 color #ffffff } box
// 明るい灰色の地面
{ y -1 s 200 0.1 200 color lightgray } box

次に、Structure SynthでSunflowにエクスポートする時に以下のテンプレートファイルを使用します。
