-
-
- This file contains the documentation specific to the Inmos version of
- POV-Ray. See POVRAY.DOC for general program info and installation
- instructions.
-
- The executable POVRAY.TLD was compiled using the Logical Systems C
- compiler version 93.1.
-
- ---------------------------------------------------------------------------
-
-
- To compile the program, you must rename INMOSCON.H to CONFIG.H and then
- invoke the INMOS batch file. This will preprocess, compile, assemble and
- link all of the necessary files.
-
- The Transputer specific source files are CONFIG.H and INMOS.C. INMOS.LNK
- is the TLNK command file and, of course, INMOS.BAT is the "quick and dirty"
- batch that automates the installation.
-
- ---------------------------------------------------------------------------
-
-
- 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>ld-one povray cio +isimple.pov +osimple.tga +w160 +h120 +b16 +v
-
- 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 +b16 +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 LD-ONE, CIO, and POVRAY to your
- path statement in your AUTOEXEC.BAT file.
-
- Note: You will need to set the buffer option (+b) on in order for POV-Ray
- to run on the Transputer. I have found that a value of 16 works well, but
- if you are rendering large images, you will have to set it larger.

-
- File Formats:
- -------------
- The default file format for the Transputer is Targa (+ft). This format
- is a 24 bit color image allowing over 16 million colors to be created.
- Most Transputerized 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.
