- Version 1.0
- IBM-PC Specific Intructions
- -------------------------------
-
- This file contains the documentation specific to the IBM-PC version of
- POV-Ray. See POVRAY.DOC for general program info and installation
- instructions.
-
- The executable POVRAY.EXE was compiled using the Intel Code Builder
- 32 bit protected mode compiler. A 386 or 486 and at least 2 meg of RAM
- are required to run this program. A math co-processor and VGA display
- are recommended.
-
- See IBMPCEXE.DOC for more info.
-
- -----------------------------------------------------------------------------
-
- Running POV-Ray:
- ----------------
- POV-Ray is run from the command line by typing the program name,
- povray.exe followed by command line options.
- For example,
-
- C:\POVRAY>povray +isimple.pov +osimple.tga +w160 +h120 +d -v +x
-
- Options may also be specified in a separate file, the name of which
- is placed on the command line. Or they may be specified in the
- environment variable, POVRAYOPT, as in:
-
- set POVRAYOPT=+w160 +h120 +x +d0 -v
-
- The environment variable is good for setting global default options
- that will be in effect no matter what directory you're working in.
- Options on the command line override the environment variable.
- It is recommended to set the environment variable in your AUTOEXEC.BAT
- file and to add the directory containing POVRAY.EXE to your path
- statement in your AUTOEXEC.BAT file.
-
- There is also at least one third-party utility available
- that runs POV-Ray from within Micorsoft Windows and provides an
- easy interface for picking files and setting options.
-
- POV-Ray outputs Targa (.TGA) files which need to be converted before
- they can be viewed on a standard VGA. See file section below for more
- info.
-

-
- Command Line Display Options:
- -----------------------------
- POV-Ray can display a rough version of the scene file while it creates
- the image by using the options listed below. To learn how to see the file
- in its final form, see the files section below.
-
- +d = Alone, will autodetect the display type and display the image
- to the screen as it's being worked on. Try specifying the display
- type explicitly if autodetect doesn't work. +d? will invoke a
- message to report what display POV-Ray is detecting.
-
- -v = Usually, you should use -v in conjunction with +d. This
- will turn off the line number text display. It will work
- with some display options. You can experiment to see which.
-
- +d#p = The first character after d is the display type, resolution is
- automatically selected. The second character is the palette type
- or color selection method.
-
- Some Examples
- --------------
- +d0h = Autodetect the VGA display type
- and display the image to the screen
- as it's being worked on.
- Use the Sierra HiColor chip and
- dithering to display more than 32,000
- colors on screen. Looks great!
- +d1 = Display to standard VGA screen 320x200.
- Try this if your SVGA display is not supported.
- +dG0 = Display to a VESA VGA adapter and
- use the HSV palette option.
- +dG3 = Display to a VESA VGA adapter and use
- the 332 palette option.
- +d4 = Display to a TSENG 400 chipset VGA using
- the 332 palette option.
-
- If your card isn't autodetected correctly try all the options.
- If no option works, just use +d1 for standard VGA.
-
- DISPLAY OPTIONS:
- +d0 Autodetect (S)VGA type (Default)
- +d1 Standard VGA 320x200
- +d2 Standard VGA 360 x 480
- +d3 Tseng Labs 3000 SVGA 640x480
- +d4 Tseng Labs 4000 SVGA 640x480
- +d5 AT&T VDC600 SVGA 640x400
- +d6 Oak Technologies SVGA 640x480
- +d7 Video 7 SVGA 640x480
- +d8 Video 7 Vega (Cirrus) VGA 360x480
- +d9 Paradise SVGA 640x480
- +dA Ahead Systems Ver. A SVGA 640x480
- +dB Ahead Systems Ver. B SVGA 640x480
- +dC Chips & Technologies SVGA 640x480
- +dD ATI SGVA 640x480
- +dE Everex SVGA 640x480
- +dF Trident SVGA 640x480
- +dG VESA Standard SVGA Adapter 640x480
- +dH ATI XL display card
-
- PALETTE OPTIONS:
- +d?3 Use 332 palette with dithering
- (Default and best for VGA systems)
- +d?h Use Sierra HiColor option. Displays
- 32,000+ colors with dithering. Looks great!
- +d?0 Use HSV palette option for VGA display
- +d?G Use Grayscale palette option for VGA display
- +d?T For Truecolor 24 bit cards. Use 24 bit color.

-
- File Formats:
- -------------
- The default file format for the IBM-PC is Targa (+ft). This format
- is a 24 bit color image allowing over 16 million colors to be created.
- Most IBM-PC systems do not have the capability to directly display
- Targa images. They must be converted to 256 color GIF images so they
- can be viewed on a VGA or SVGA display. To convert a TGA file to a GIF
- file, get a copy of PICLAB or Image Alchemy which can be found from
- the same source as the POV-Ray files. The program documentation
- of these programs describes how to convert a TGA to a GIF.
-
- Many SVGA cards now have a Sierra HiColor chip for 16 bit color.
- Get a copy of the program TGVIEW and you can see your rendered images
- in "almost" full color without converting them to a GIF file.
