はじめてのFujiyama Renderer　その1

Fujiyama Rendererをさわる。
CentOS6.3 x86_64でビルドした。

Python APIを利用する。
fujiyama.pyはbinフォルダに置いた。

はじめてのFujiyama Renderer　その8　視野変換

とりあえず、カメラ位置と注視点位置から視野変換するPythonスクリプトをRenderMan資料placecam.cを参考に求めてみました。ありがとうございます。
まちがっているところもあるかもしれませんが、それっぽくカメラ位置が求められています。
Fujiyama Rendere0.1.1では、変換の順序は、プロパティを設定する順序に
影響しません。記述の順番は関係しません。
順序を設定するためのプロパティは'transform_order'、
'rotate_order'になり、デフォルトではそれぞれ、ORDER_SRTと
ORDER_XYZになっています。
変換はスケール、回転、移動の順に行われています。
回転はx,y,z軸回転の順に行われています。

以下のfujicam.py、Pythonスクリプトを実行し、出力された変換をコピペでシーンに張り付けてください。なおroll、coneangleは未対応です。
