- Notes for PVPRO BETA 0.5
- Based on DKBTRACE
- by David Buck
- -----------------------------------------------------------------------------
-
- THIS IS A BETA VERSION!
-
- This is a 32 bit version of PVRay. It has been compiled for 32 bit
- protected mode with Intel's 386/486 Code Builder Kit. Please Note: It
- *ABSOLOUTELY REQUIRES* the following:
-
- 80386SX, 80386DX or 80486 Based machine.
- 80387SX, 80387DX or the built in 80486 CoProcessor or a 487SX.....
- AT LEAST 2 Megs of RAM, preferably 4Megs. (The more the better though,)
- (it'll use it all. )
- (Note: I have been told that some people have been unable to run the )
- ( program with only 2Megs of RAM installed in their machine. )
-
- A Hard Disk is Preferred. Since a Virtual Memory Manager is linked into the
- program the disk can be used as swap space much like what Windows 3 (TM)
- does to add additional "memory". (See PVPROMOD.DOC for notes on how to modify
- the amount of hard disk space that will be used by the Virtual Memory
- Manager. This is *NOT* dynamic and must be adjusted according to your
- individual systems available resources.)
-
- The program *WILL NOT RUN* on 8088, 8086 or 80286 based systems!
-
- If you get a message at startup about an incompatible extended program
- in operation, *REBOOT* your machine IMMEADITATLY, --- dont continue!!!
- File corruption can result if you continue!!! (This according to Intel
- Doc's) Then re-start with a "bare" system.
-
- The program will only run in harmony with relitivly new extended memory
- applications. The other application *must* be DPMI 0.9 compliant for both
- of them to operate at the same time. (Most are not, disk caches, XMS->EMS
- converters etc.) The program will not run with QEMM installed. If you
- intend to be tracing only (I.E. "single tasking" so to speak) QEMM's
- functions are un-needed anyway. PVPRO *WILL* run in concert with QEMM
- 5.1x UNDER WINDOWS 3.0 in ** 386 ENHANCED MODE **. VCPI applications are
- incompatible with PVPRO.
-
- Please let me know if you find any errors or quirky operation.
-
- The Display option seems to work. It has only been verified on a Tseng
- 3000/4000 based cards and an ATI VGA Wonder at this time however. **The
- VESA modes are disabled in this version, still working on them.** In most
- cases the hardware autodetect routines should work fine. See the doc
- files for more info on the video hardware supported.
- ** NOW SUPPORTS DIRECT RENDER TO SCREEN IN 32,768 COLORS on TSENG 4000
- based cards with the Sierra HiColor DAC! Use +d0H in PVRAY.DEF to
- enable autodetect and the HiColor modes. --- Note: Some cards may have
- problems running HiColor modes at less than 640x480 resolution. My revision
- C5 Diamond Computers SpeedSTAR+ HiColor works fine in the 320x200 mode,
- most cards *do* seem to, although it's not an "advertised" mode.
- Original IBM.C port by John Gallagher.
-
- A "Trace Time" has been added to the statistics report at the
- end of a run. It will report the number of Min & Sec that the
- actual trace took. (Excluding parsing and swap file setup since they
- are *highly* variable depending on the machine/disk speed and the size
- of the swap file allocation.) It displays to the nearest second, the
- 10th's and 100th's will always be 00. (I.E. XXXXX.00 Seconds).
-
- Other than these differences PVPRO is exactly the same as the DOS
- version. It will, however, trace MUCH-MUCH larger image sources. It didn't
- crash on me with the composite in ROMAN.DAT tripled, I have also mapped in
- as many as 3 200+K GIF's in the same image.
-
- If you come up with any interesting huge models please let me know!
- I am also interested (just for curiosity's sake) in anything that DOES manage
- to crash the program. I have found it to be about 20% faster than the
- MSC 6.0a DOS version, as well as about 40% faster than a Turbo C compile on
- my 25Mhz Non-Cached '386. I've been told that the speedup on a '486
- based machine is even better.
