Creating and Using a Config File

 back to top

Some parameters for RapidCompact CLI are directly available with the respective commands. However, many relevant options (like the choice of a specific algorithm for a certain task, or the resolution for a specific type of texture image) are only available via the settings mechanism of RapidCompact CLI. The ratio behind this is to ease usage of the command line, especially for users that are not familiar with all the details, while still allowing you to configure all relevant parameters when necessary.

One way to configure the settings is to use a config file. The config file is a text file in JSON format, which can be easily edited. To create one that already contains the default values for all the available settings, use the command write_config with a filename. Example:

         rpdx --write_config rpd_config.json         

Additionally it is possible to just use the short command write_config without an argument. The resulting file will always be named as default: rpd_config.json Example:

         rpdx --write_config

This example writes a config file with filename "rpd_config.json". This special filename is used by RapidCompact CLI to check, on startup, for an existing config file inside the current directory. If the file has another filename, or if it is placed at another location, you can use the read_config command to read it when launching RapidCompact CLI. Example:

         rpdx --read_config someDirectory/myConfig.json         

Changing the settings inside a config file is pretty straightforward - just use your favorite text editor to alter the default values and save the file. When looking into a config file, you will notice that settings' names are using a URN-like scheme, separating several parts of the name by a colon. Examples:

             [...]
             "decimation:method" : "quadric",
             "rendering:imageWidth"  : 1024,
             "rendering:imageHeight" : 1024,
             [...]

The colons are used to separate different parts of each setting's name, where the first part is always the subsystem of RapidCompact CLI that uses the setting. In the above example, for instance, the prefix "rendering" tells us that the following part "imageWidth" refers to a setting inside that subsystem (and nowhere else). For example, the width of images for texture generation will not be affected by this setting.

 

Changing Settings using the Command Line

 back to top

Sometimes, you might want to try out different settings without having to use a config file. This is easily possible by using the command set (shorthand: s). Example:

         rpdx -i myMesh.ply -s decimation:method edgeLength --decimate v:10% -e myMesh-decimated.ply         

In this example, a mesh is loaded and its 3D geometry is decimated to 10% of the original vertices. Instead of using the standard decimation method or the one from the default config file, it is explicitly set to edgeLength before the decimater is used.

In general, the default value of a setting can be overriden in both ways, using a config file or using the command line. Both methods, using a config file and using s on the command line, override the current values of the given settings, so the current value of a setting also depends on the order in which previous read_config or s commands are executed. If you have use for this, you can also split up one large config file into multiple smaller ones, to separate different aspects of configuration. This is possible since the settings specified inside the config file do not need to be complete. Instead, a config file will only override settings for the parameters that are specified, leaving unspecified settings untouched. Example:

         rpdx --read_config decimation_config.json --read_config rendering_config.json ...         

Finally, to print the current value of a setting, there is also a get command (shorthand: g).

 

Changing Logging Verbosity

 back to top

By default, RapidCompact CLI will print some information to the standard output while executing commands. By specifying a log level, you can influence how verbose this output will be. To do so, use the "logging:infoLevel" setting. The corresponding values are:

• 0 - NONE: quiet mode, no logging
• 1 - ERRORS: only errors are shown
• 2 - WARNINGS: only errors and warnings are shown
• 3 - INFOS: errors, warnings and regular info messages are shown
• 4 - DEBUG: verbose mode, all information available is shown
