Features
This section lists significant new features in the Unix version of POV-Ray 3.6, compared to the last release (3.5). It does not list new features of the rendering engine, but only of the Unix version.
I/O Restrictions
The Unix platform specific part of the I/O Restrictions feature has been redesigned for POV-Ray 3.6. The configuration file format has changed as well as the way the settings are interpreted. How the I/O Restriction can be controlled in the Unix version is described in the I/O Restrictions Documentation.
As a quick summary, I/O Restrictions control where the POV-Ray core code may and may not read or write files. By default, this is turned on and is fairly restrictive (read/write is allowed in the directory that the main input file is in, and read is allowed in the standard installation directories).
Note: The I/O Restriction code may not be completely mature yet. Please report any bugs you may find.
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.
Benchmark Mode
POV-Ray 3.6 for Unix provides a new mode to render a built-in version of the standard POV-Ray benchmark scene. See the Benchmark Rendering Mode documentation for details.
Sample scene render scripts
POV-Ray 3.6 includes a set of shell scripts to automatically render all the samples coming with POV-Ray and that generate HTML files to easily browse the sample scenes. See Rendering the Sample Scenes for more information.
KDE integration
The binary package for x86-Linux (povlinux.tgz) comes with
an install script that generates some useful entries in the
KDE panel for convenient
access to the POV-Ray documentation and configuration files.
The generic Unix source distribution also comes with the
kde_install.sh script to perform the same task.
This script is derived from the install script above.
What's new in POV-Ray for Unix
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.
- Reworked
--benchmark: - The built-in benchmark now accepts
+L<path>command-line options - now ONLY reads the provided any INI file.
- 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).
- Added support for 'pause when done' in linux build.
- Added support for
--benchmarkon unix works together with+wtand print built-in features with--version - Unix default file gamma changed from from 1.0 to 2.2.
