SketchUp でパラメトリックモデリング [03]

Rhinoceros の Grasshopper や Revit の Dynamo にはまだまだ機能的には追いついてはいませんが、今年の２月末に、SketchUp でパラメトリック・モデリングを実現するプラグイン Viz for SketchUp が Early Beta 版 (ver.0.1.0) としてリリースされました。

当初、WIN only でしたが、今回のアップデート (ver.0.3.0) で MAC にも対応するようになりました。前回５月末のアップデート (ver.0.2.1) ではカスタムノードに対応しましたが、今回さらに新たなノードが追加され、Extrude やテクスチャマッピングもできるようになりました。

現状、まだマニュアルやノードの解説などが見当たらないため、とりあえずサポートされているノードをヘルプメッセージを頼りに一覧表にしてみました・・

ver.0.2.1 にあったいくつかのノードは、ver.0.3.0 で統合されたりしているものもあるようなので、古いソースとは互換性がなっくなっている様です。というか、絶賛開発中ということですね・・・

公開されているサンプルファイルを開いて、いろいろ試してみようと思います・・
