Use the given title for the window -icon Start iconified -borderwidth <width> Use a border of the given width in pixels -help Output these X Windows options File Formats: The default file format for SINIX is "TGA" format (+ft). Optionally, the "PPM" format, popular on UNIX platforms, or the new "PNG" format can be set as the default output format by setting "Output_File_Type = p" or "Output_File_Type = n" in your .povrayrc file or by using +fp or +fn on the command-line. If you are generating histogram files in the CSV format (comma separated values), then the units of time are in tens of microseconds (10 x 10^-6 s), and each grid block can store times up to 12 hours. Interrupting POV-Ray: To interrupt a rendering in progress, you can use CTRL-C (SIGINT), which will allow POV-Ray to finish writing out any rendered data before it quits. You can also press the 'q' or 'Q' keys in the rendering preview window to interrupt the trace if the Test_Abort (or +X) flag is set. Post-processing Images: For UNIX systems, the PBM utilities are an excellent choice for post-processing utilities, especially if you are running on a console. They are included in the switls package shipped with SINIX/windows (this package is not installed by default). Not that the xv delivered with SINIX/windows is not able to display TGA images. You have to convert them to a different file format. In order to convert an image in TGA format to GIF format, you may issue the following commands: tgatoppm <file.tga | ppmquant 256 | ppmtogif >file.gif -- Siegfried Hempfer | Tel: +49/(0)89/636-41553 | Experience: Something SNI AG, OEC ES DX2 | Fax: +49/(0)89/636-41215 | you don't get until Otto-Hahn-Ring 6 | eMail: hempfer.muc@sni.de | just after you need it.

This file contains the documentation specific to the SINIX version of POV-Ray. This archive contains both an X (x-povray) and a non-graphical (povray) version of POV-Ray 3.00a. The non-graphical version is about twice as fast as the X version due to the special math library. /****************************************************************************** * Note that this port is not supported by the POV-Ray Team(tm). * Use at your own risk. *****************************************************************************/ The port was based on the source code available from www.povray.org. I used the CDS 1.1 compiler with the following flags: -O -Wb,-r4000 -Wb,-mips3 -Kr4000 The non-graphical version was linked with the additional flags -dn -lm_r4000 Using -lm_r4000 instead of -lm_s seemed to fix the problems I had with some pov files. I tested this program on an RM400 running SINIX-N 5.42B0032. The package itself is based on the linux distribution with the binaries and the README replaced. For a default installation, go to /usr/local/lib and do a mkdir -p /usr/local/lib mkdir -p /usr/local/bin cd /usr/local/lib gzip -cd < INSERT_PATH/povray.3.00a.tgz | tar xvf - mv povray3/povray /usr/local/bin mv povray3/x-povray /usr/local/bin mv povray3/povray1 /usr/share/man/man1 cp povray3/povray.ini $HOME/.povrayrc The preferred location for installing POV-Ray for SINIX is under /usr/local/lib/povray3 for all of the INI, scene, and include files, and /usr/local/bin for povray and x-povray. Each user will also need to have an INI file to tell POV-Ray where to look for these files. The POV-Ray man page, povray.1, should be placed in a similarly accessible location, such as /usr/share/man/man1. If it is expected that many people will be using one version of POV-Ray, it would be a good idea to edit povray.1, under the section 'FILES' to specify where all of the documentation, scenes, and include files are actually stored, if they aren't installed as suggested above. INI files: POV-Ray allows the use of files to store common configuration settings, such as the output format, image size, and library paths. If the environment variable POVINI is set, then POV-Ray will look at the file that POVINI is pointing to to read configuration information. If POVINI is not set, then POV-Ray will try to read the file ".povrayrc" in your home directory, or failing this, it will try to read the file "povray.ini", in the current directory. The POVRAYOPT environment variable is no longer used by POV-Ray. The default povray.ini file that is shipped with the SINIX archive assumes that POV-Ray will be installed under /usr/local/lib/povray3. If you are not installing POV-Ray there, you should edit the Library_Path specifications in this file to point to the location where POV-Ray is installed. Each user should copy this file to ".povrayrc" in their home directory. The other INI files, like zipfli.ini and tgaflc.ini are of limited use under UNIX, but are included as examples of how to automate operations from within POV-Ray, and can be customized to use whatever programs you have installed. X Window System display: During rendering, the window will be updated after every scanline has been rendered, or sooner if the rendering is taking a long time. To update it sooner you can click any mouse button in the window or press (almost) any key. Pressing or during rendering will refresh the whole screen. The rendering will pause when complete if the Pause_When_Done (or +P) flag is set. To exit at this point, press the 'q' or 'Q' key or click any mouse button in the rendering window. The xpovicon.xpm is a color icon for use with fvwm or other window manager which can use external icons. To have fvwm use the icon, move it to the directory pointed to by your PixmapPath, often /usr/include/X11/pixmaps/, add the following line to your .fvwmrc: Style "Povray" Icon xpovray.xpm and re-start X Windows. Re-starting fvwm will not be enough. If you don't restart, or choose not to do this this, POV-Ray will use a similar built-in monochrome icon. The X-windows version also supports these standard command-line options in addition to those given in the generic POV-Ray documentation: -display Preview on the specified display -geometry Start with the given size and position -visual Use specified visual if available -title Use the given title for the window -icon Start iconified -borderwidth <width> Use a border of the given width in pixels -help Output these X Windows options File Formats: The default file format for SINIX is "TGA" format (+ft). Optionally, the "PPM" format, popular on UNIX platforms, or the new "PNG" format can be set as the default output format by setting "Output_File_Type = p" or "Output_File_Type = n" in your .povrayrc file or by using +fp or +fn on the command-line. If you are generating histogram files in the CSV format (comma separated values), then the units of time are in tens of microseconds (10 x 10^-6 s), and each grid block can store times up to 12 hours. Interrupting POV-Ray: To interrupt a rendering in progress, you can use CTRL-C (SIGINT), which will allow POV-Ray to finish writing out any rendered data before it quits. You can also press the 'q' or 'Q' keys in the rendering preview window to interrupt the trace if the Test_Abort (or +X) flag is set.
