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

Paul de Leeuw has been working for some time on a Windows API port of Fractint. At his request I have put the program and the source in http://www.fractint.org/ftp/experimental/MANPWIN.zip and http://www.fractint.org/ftp/experimental/ManpWinSrc.zip His version supports truecolor and can due color cycling. He'd love to have some help. I'm itching to get back into Fractint myself but haven't decided where to dive in yet. I have a full life, so until I actually do this it's just an idea :-) Paul, since your source, though based on Fractint, is yours, maybe the first thing to do is to put the code under an open source license. I'd suggest GPL (but this would be up to you). In fact maybe what I ought to take on is the mundane task of GPL'ing fractint. This would mean going through the code module by module, and changing the license of the files we have copyright to, and gaining permission or rewriting or removing the rest. Tim

Next patch

Tim, I've decided to back the assembly language formula parser changes out of the next patch. Still can't get it to work. Running the C code through -Wall has fixed a couple of bugs that we barely new existed. I do want to run the patch through the DOS code and see what breaks before I release it. That may take a while. As it stands, the next patch is going to be huge. There are only a couple of actual bug fixes in it (or will be in it). Jonathan

Tim, The diff for the version 20.2.03 patch is now on the developer's web site. The Xfractint source is there also. I'll work on the Fractint files now. Jonathan

Xfractint

Tim, The parser assembly code is running but produces no image. I've fixed several segmentation faults, including one that was occurring when a fractal type has no parameters. Increasing the iteration count increases the time the non-image takes to generate. It appears the formula is being processed more or less correctly. I know there are still some problems with certain op codes, but I can't check them until I can see an image. It looks like the pointer to Z is set correctly and the new value is getting back to the C code. There may be a problem with eax as it is passed back to C, but that should make the code bailout all the time. Have you run into anything like this before? I'm hoping the solution occurs to me shortly, it usually does within hours of sending one of these emails. 8-)) Jonathan
