The 3delight.ini Configuration File

Some of the default options are settable through the 3delight.ini initilization file. The renderer looks for it in four different locations, in order:

1. In 3Delight's installation directory, as specified by the $DELIGHT environment variable.
2. In the directories specified by the $DELIGHT_CONF environment variable (a colon separated list).
3. In user's home directory, as specified by the $HOME environment variable. It also looks for an `.3delight.ini' file in the same directory.
4. Finally, 3Delight tries to load `3delight.ini' in the current directory.       ← Do we need this ???

If 3Delight encounters the file in more than one location, it uses the latest keys and values it finds. This enables the user to have a site specific initialization file in the $DELIGHT or $DELIGHT_CONF directories and user specific settings in their home directory.

Each line in the configuration file is of the form "key value1 [value2 ... value_n]". The key being a recognized 3Delight configuration options as listed in the table below.
