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。

以下は、Nupatchのcone.ribを保存します。

Aqsis1.6とguile-rmanでのサンプルが動くように調整しました。

以下、test0.scmを実行します。
Some deprecated features have been used. Set the environment variable GUILE_WARN_DEPRECATED to "detailed" and rerun the program to get more information. Set it to "no" to suppress this message.

export GUILE_WARN_DEPRECATED="detailed"
