Some bugs. Fixups useless?
by Charlie Chernohorsky 10 Jul '02

10 Jul '02

Hi all, this is my first post.. :ox Since bug-list is suffering nowadays, I repost it here: (and just hope this isn't a faux pas) 1. L-system "Thinking" screen freezes up upon this: (Under W98 it announces a restricted instruction or st. like that) Bug { angle 6 axiom F F=[F+F- F=-F+F] } It's somehow caused by spliting related push-pops into multiple lines. 2. Vertical lines all over the screen, when using mode with color bit depth more than 4 bits (16 colors) on a Chips&Techs card. It supports VESA well enough and my own plotings are clear. None of the textsafe options did help. 3. Therefore while wondering thru video.asm I found some bad things: VESAtruewrite in 24+b/color mode forms B-G-B instead of R-G-B (caused by commenting out some lines, but most of the cards require B-G-R anyway, so that branch is rarely passed thru I guess) VESAtruewrite/read and put/gettruecolor in 24+b/color mode call VESAtrueaddr three times! (While calling it once is enough!) So, I rewrote these, it now does about 150% of job in the same time. But then I realised that development is possibly heading a very different way (no asm), so my last question is, should I send video.asm fixups to someone or instantly throw away? thanx, charlie ______________________________________________________________________ Reklama: Volkswagen nyni nabizi akcni model Golf Edition s klimatizaci v cene 36 900 Kc zdarma. http://ad2.seznam.cz/redir.cgi?instance=28672%26url=http://www.volkswagen.c…

Fwd: XFractint 20.02.4 boundary tracing bug on 24-bit servers
by Scott D. Boyd 26 Jun '02

26 Jun '02

I'm forwarding the following email (bug report) to this list. I was able to reproduce the bug described in his email, although I run a 16-bit X-server. I don't *think* the bug is only in my pre-compiled Xfractint package. Jonathan or Tim - can you reproduce the bug? Scott Boyd ---------- Forwarded Message ---------- Subject: XFractint 20.02.4 boundary tracing bug on 24-bit servers Date: Mon, 24 Jun 2002 00:29:43 +0300 From: George Tsegas <gtseg(a)skiathos.physics.auth.gr> To: sdboyd56(a)swbell.net Hello there. I recently downloaded the XFractint 20.02.4 binary from your web page. The "hit feature" of this release is, of course, its support for non-8-bit color depths, which is really convenient since there's no need any more to start a seperate 8-bit X-server in order to run xfractint correctly. I stumbled on one minor bug, though, that seems to be related to the 24-bit color depth support: using the "Boundary Tracing" drawing mode in some cases seems to lead to an infinite loop: XFractint seems to "freeze", drawing halts and the program only responds to <Ctrl>+C. The bug is reproducible by starting xfractint (on a 24-bit server), then choosing "Run saved command set" and selecting Peter Moreland's "Blue" command set from the file "fractint.par". It stops after only a small line segment is drawn on the top-left corner of the window. Same thing happens with other fractal types too, though not always. The exact same procedure does work correctly on an 8-bit server, on the same machine. Hardware: Athlon XP 1900+, 512MB DDR RAM (standard clocking) Gainward/NVidia GeForce4 Ti 4400 (standard clocking) Software: RedHat Linux 7.2 (+all the official RedHat updates) Kernel 2.4.9 glibc 2.2.4 XFree86 4.1.0, server running @ 1280x1024x24bit NVidia closed-source kernel module + GLX driver, ver. 1.0 29.60 KDE 2.2.2 ('official' RedHat packages) Thanks again for your effort. Please let me know if I should forward this bug report to somebody from the {X}fractint development team. -- George Tsegas gtseg(a)skiathos.physics.auth.gr "The only real way to look younger is not to be born so soon."

CVS

Hi Tim, I'll have a go at hosting CVS if you like, I've yet to determine what my cable connection is like for such things so I'll stick a recent patch of xfractint in and set you and Jon up with accounts on my cygwin setup so you can use ssh to access the repository. I've also written up some quick howto's for the other UTron project coders so I'll post them as well. Probably get it done over the weekend, watch this space :-) >On another subject, what is the problem re Fractint and XP? Probably the same as with NT and win2K, they all use a HAL type setup so direct hardware access is out. Though 2K and XP can both use directx. I wonder if any windows whizz out there could do a directx wrapper in fractint for video and keyboard access, that'd be cool :-) Cheers, Robin. ------------------------------------------------- This mail sent through UK Online webmail

XFractint source file permissions
by Jonathan Osuch 10 Jun '02

10 Jun '02

Tim, How do we want the permissions set on all the source files? Do we want to modify the distribution to change all the instances where file names contain capital letters? I know, I just fixed Xfractint so this would work, but I find the capital letters irritating. Jonathan

A problem compiling Xfractint 20.2.04
by Scott D. Boyd 05 Jun '02

05 Jun '02

Tim or Jonathan, I've *finally* gotten around to trying to compile Xfracint 20.2.04. Seems like curses.h is missing. Should I grab a copy from an older version? Below is the last 3 lines from the "make" command: gcc -I. -DXFRACT -DNOBSTRING -g -DBIG_ANSI_C -DLINUX -Os -c -o realdos.o realdos.c realdos.c:10:20: curses.h: No such file or directory make: *** [realdos.o] Error 1 Until later, Scott Boyd

Scott, I've got Mandrake 8.2, but my modem doesn't work with it. Therefore as I'm in Windows, I can't check that this is exactly right without rebooting and I can't be bothered to do that. On the desktop there ought to be a shortcut to the Mandrake Control Centre, then in the system part there is something like Software Manager. You might need your CD in it for it to be able to list the packages, but apart from that it's intuitive. I don't think you can make do with just the header file, you need the library and so the whole package. From, Rupert P.S. If this is a load of nonsense please excuse me because I have only had Linux for a few months and Mandrake 8.2 a few days. >From: "Scott D.

Bootable Xfractint CD
by Tim Wegner 03 Jun '02

03 Jun '02

Jonathan, I have been experimenting with partimage, a Linux program somewhat like Norton Ghost for backing up partitions. A good way to use it is to boot Linux from a bootable CD and run partimage from there. I bought a 100 mb drive, and can back up all my computers to this drive over the network. (see http://www.partimage.org and http://rescuecd.sourceforge.net/ for more info. Unfortunately this takes just a bit of knowledge to use.) It occurred to me that it would be very easy to create a bootable CD booting Linux with Xfractint on it. These CDs create a RAM disk with a miniature Linux on it. Linux, of course, can access Windows file systems, so the resulting fractals could be saved to disk and accessed under windows. This could be put on one of those baby-sized CDs. I am not sure how practical this is. To be workable, it would have to be extremely easy to use since the target audience for this would be people who have Windows but don't want to install Linux. More Linux- knowledgeable people would already have Linux on their PCs. Just a thought. Tim
