New 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.

1. Reworked --benchmark:
• The built-in benchmark now accepts +L<path> command-line options
• now ONLY reads the provided any INI file.
2. Added preliminary Linux support for these two features:
   • CPU timer; might return incorrect results depending on the platform.
   • signal catching (e.g. when aborting a render by hitting Ctrl+C).
3. Added support for 'pause when done' in linux build.
4. Added support for --benchmark on unix works together with +wt and print built-in features with --version
5. 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 (SVGAlib) on the console (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.
