- with further optimizations.

- Notes for QRTPRO.EXE
- ==============================================================================
-
- This archive contains a port of QRT version 1.5 for use on IBM
- compatible machines with *at least* an 80386(SX) CPU. The program will
- use a math coprocessor if one is installed in the machine, if not
- a protected mode '387 emulator will be loaded and used. The program
- *may* execute in a machine with 2 megs of RAM although 4 is better.
- The program POVMOD included in the archive of POV-Ray 1.0 or 2.0 may
- be used to change the amount of disk space the virtual memory manager will
- use. (POVMOD.EXE is in the POVIBM.ZIP file in the POVSOURCES library
- of the Graphics Developers Forum (GO GRAPHDEV) on CompuServe) The
- region size is currently set to 2048K in this EXE which should be
- enough for QRT. See the doc file with POVMOD (POVMOD.DOC) for further
- information.
-
- For further documentation on QRT download the file QRT15E.ZIP from
- the raytrace libs in GRAPHDEV on CompuServe. That file contains Doc's
- as well as a Turbo C 2.0 real mode compile of the program that will run
- on any IBM compatible machine. (No use duplicating Doc files in several
- files, the real mode executable program is quite a bit smaller than
- this one, a good part of the file size of that ZIP is Docs.) This compile
- runs approximatly 40% faster than the real mode version in QRT15E.ZIP
- however. It will also report the time required to trace the image, in
- seconds, in the statistics report at the end of the run.
-
- For a quick starter the syntax to run one of the example files
- included here (from the command line prompt) is:
-
- QRTPRO < MIRRORS.QRT
-
- This will generate a 24 bit TARGA file called MIRROR.TGA.
-
- =========================================================================
-
- If you get a message about a conflicting protected mode environment
- being detected, reboot your machine with *no TSR's or memory management*
- programs. QRTPRO should now run with most *current versions* of memory
- managers on the market installed. Some VCPI applications, however, are
- still incompatible. This version will run under OS/2 2.x as a background
- task. DPMI_MEMORY_LIMIT (under DOS SETTINGS) must be set for 2+ Megs.
- To run stand-alone under Windows 3.x your machine *MUST* have a
- coprocessor installed. If your machine does not have a coprocessor
- installed you must copy the VEMD.386 file to your Windows subdirectory
- and add the following line to your SYSTEM.INI file in the [386enh]
- section:
-
- device=<path>\VEMD.386
-
- Where <path> is the DRIVE and PATH to the directory that contains VEMD.386.
- Case is not significant.
- =========================================================================
-
- This version of QRT writes a TARGA type 2 (uncompressed) file
- *ONLY*. It also assumes the video display is EGA or VGA for text
- output, although any should work. You may end up with wierd
- attributes on a mono display. Various programs can be used to
- convert the output to an S-VGA viewable file. Lee Crocker's program
- "PICLAB", available in the Graphics Support Forum on Compuserve, will
- do an excellent conversion to a GIF file which can then be viewed
- with any GIF viewing program. The image can be edited and/or
- converted with a commercial paint program such as ColoRix.
-
-
- See READ_ME.TXT for information on QRT's author and the program.

- Have Fun!
