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 the following 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, the 3delight.ini in the current directory.       ← Do we need to keep this ???

If 3Delight encounters the file in more than one location, it uses the latest keys and values it finds. So that later options settings override former ones. 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 one of the recognized 3Delight configuration options as listed in the table below.

The following text is the default 3delight.ini file content (included in the 3Delight's installation directory):

# This 3Delight.ini file allows you to set some configuration options.  The format
# of this file is simple: each line is a key/value pair linking an option to a
# specific value. Lines starting with a "#" charachter are ignored (they serve as
# comment lines). Example:
#
#   networkcache.directory /var/tmp/3DelightCache
#
# Recognized keys are listed below:
#
#   networkcache.directory
#       Specifies the location of 3Delight's texture cache.
#
#   networkcache.size
#       Specifies the size, in GB, of the texture cache.
