Lightflowのカラーサンプル

POV-Rayではcolor.incというカラーサンプルが定義されている。Lightflowで似たようなことができないか使い方を検討やってみた。
まず、Pythonで読めるように、ファイルをEditorを使って整えた。
ファイル名はcolorinc.py
以下のように記述した。



#! /usr/bin/env python

#colorinc.py

後はLightflowでシーン記述したファイルの中で実際に呼び出すために、
import colorincと記述しておき、色呼び出しの際は、
colorinc.DimGray
colorinc.BlueViolet
と記述してあげると、指定の色が呼び出される。
以下、サンプルを参考にしてください。
