Paul?

Hey, did Paul get CVS access? Paul, were you able to compile the branch with VC++ 2005 Express? I did put some tweaks in there to get everything to compile with no warnings on the Express edition. I haven't put a copy of VS.NET 2003 Academic Edition in the mail for you yet, but its coming... -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

DivideBrot5 status
by Jonathan Osuch 19 Sep '08

19 Sep '08

Tim, I've gotten the floating point version of DivideBrot5 to work in both Fractint and Xfractint. The bf math also works. bn math does not work. Along the way several functions that hadn't been used before in Xfractint were fixed for both the fp and bn math. Also fixed the bn math version of manzpower. Manzpower now works with some small artifacts appearing in the center of lake(s). The artifacts go away when the intlength is increased to 4 (from 2). I'll change the default to 4. The only thing left is to fix DivideBrot5 with the bn math. Jonathan

I just got an email from MS where I learned that there is a SP1 for Visual Studio 2008: "Finally, we've been excited for some time about the new features in Visual Studio 2008 SP1. So it's gratifying when others notice. Check out this InfoWorld review, "Visual Studio 2008 SP1 Is Icing, and More Cake," which takes a look beyond the bug fixes in Visual Studio 2008 Service Pack 1 (SP1)..." - Hal Lane ######################### # hallane(a)earthlink.net # #########################

atan2_bf() problem
by Jonathan Osuch 06 Sep '08

Tim, It appears that atan2_bf() in bigflt.c isn't working correctly. This affects cmplxlog_bf() and thus ComplexPower_bf() in fractalb.c. This can be seen by starting up the manzpower fractal type and then switching to arbitrary precision math using debug=3200. I found this while I was coding the dividebrot5 fractal. In the case of the dividebrot5 fractal, Fractint locks up. With the manzpower fractal, an image is generated, but not the correct one. Jonathan

Athlon woes
by Tim Wegner 03 Sep '08

03 Sep '08

I built a computer last year using an Athlon with a Gigabyte motherboard. I had troubles with Fractint - with any SVGA mode the computer would hang after the completion of the image. I always assumed this was an Windows XP issue. Today I tried Fractint with freedos on the same computer, with the same results. So apparently it's an incompatability bgetween fractint and my compuiter. Truecolor, 320x200, diskvideo, and even tweaked modes work. SCGA modes fail, and only after the image completes. This behavior appears to have nothing to do with recent versions. Has anyone else had trouble with Athlon? Hmm, maybe I need to look at bios settings. Tim
