Rendering学習日記

日々3DCGの世界は進歩しているけど、勉強して理解したことをまとめていきたい。RenderMan互換レンダラーやグローバル・イルミネーション。いろんなことに好奇心を持ち面白くなってくる。目指せShader書き!!

<< はじめてのFujiyama Renderer その29 | main | Guile RMan #13 サンプルテスト >>

Guile RMan #12 RiReadArchive

Aqsis1.6とguile-rmanでのスクリプトの書き方、ReadArchiveの書式がわかりました。

(RiReadArchive "cone.rib" (list ))

パラメータ部分をlistにしときます。
