On the Unix platform PPPPOOOOVVVV----RRRRaaaayyyy can be either a text-mode only program, or can optionally have preview capabilities using the _X _W_i_n_d_o_w _S_y_s_t_e_m. Under Linux, PPPPOOOOVVVV----RRRRaaaayyyy can optionally use the SVGA library to preview renderings. This manual page only lists the basic PPPPOOOOVVVV----RRRRaaaayyyy and Unix specific features and command-line options for this version of PPPPOOOOVVVV----RRRRaaaayyyy. For a complete description of the features of PPPPOOOOVVVV----RRRRaaaayyyy and its scene description language, or for a better explanation of the meaning of the command-line and INI file options, please consult the documentation that should accompany all versions of PPPPOOOOVVVV----RRRRaaaayyyy. On some sites this will be installed in /usr/freeware/lib/povray31. Some of the Unix specific features are: Support for X Windows display automatically uses the best visual class and deepest depth available. For visuals that do not support 24 bits of color per pixel, Floyd-Steinberg error diffusion dithering is used, along with a dynamically allocated and optimized palette to produce the best display possible with the current visual, depth, and available colormap. ICCCM compliance for the X Windows version means that the preview window will behave like standard X Windows programs, communicate properly with the window manager, and will accept the standard command-line options. See _X(_1) for more information. Support for SVGAlib display automatically detects the available SVGA display modes to choose the size which best fits the rendered image. When rendering an image that is too large for the current display, the displayed image is scaled to fit on the screen. For displays that do not support true-color modes, Floyd-Steinberg dithering is used. ASCII graphics in the text-mode version allow a basic view of the current rendering on text-only terminals. Page 1 (printed 4/6/99) PPPPOOOOVVVV----RRRRaaaayyyy((((1111)))) PPPPOOOOVVVV----TTTTeeeeaaaammmm ((((4444 MMMMaaaarrrrcccchhhh 1111999999999999)))) PPPPOOOOVVVV----RRRRaaaayyyy((((1111)))) An interrupt handler allows rendering to be interrupted in a safe way, so that any data not currently written to disk will be saved before exiting. Control-C or SIGINT will cause a user abort, and save the current rendering, before exiting. See _k_i_l_l(_1) for more information. Platform and architecture independent rendering means the same scene will render in the same way on all computers and operating systems (with the exception of the rendering speed, of course). OOOOPPPPTTTTIIIIOOOONNNNSSSS Options can be specified with either a leading '+' or a leading '-'. Many options are switches, meaning a '+' turns the option on, and a '-' turns the option off. For other options, it doesn't matter if a '+' or a '-' is used.
