Features

This section covers version 3.7 changes and new features that apply to POV-Ray for Unix. See the section Changes and New Features Summary for information about non-platform specific changes.

New Features

1. Reworked the built-in --benchmark
• The built-in benchmark now accepts the +L<path> command-line option
• and now ONLY reads the provided any INI file.
• It also accepts +wt to set the number of work threads
• and now also accepts the --version parameter
2. Added preliminary Linux support for these two features:
   • CPU timer; might return incorrect results depending on the platform.
   • signal catching when aborting a render by hitting Ctrl+C
3. Added support for the +P option to allow pause when done.
4. Unix default file gamma changed from from 1.0 to 2.2.

Display Options

The Unix version now has a single binary which supports display using the X Window System, or using the SVGA library with the console on GNU/Linux systems only, or via text graphics otherwise. If the command-line options or INI files turn on display, the following heuristic is used to determine what kind of display should be used. If the DISPLAY environment variable is set, the X Window display is used. Otherwise, if the user is on the console, and has permission to do so, SVGAlib is used. Otherwise, text graphics are used.

Text graphics display a crude 75x24 ASCII version of the image which can be useful none the less to monitor the render progress on a text terminal. Using text graphics and the Verbose +v option simultaneously will not work very well.

Note: See the section Known Bugs for more information about a problem with the X11 windows.
