Part of the problem is the difference between the formula parsers. The Xfractint code is using the C parser and Fractint uses the assembly parser. There is something else going on, also, because the image generated using Fractint with debug=90 (to force the use of the C code) doesn't match what we are seeing. I'll have to look into it.
Yes, my Win32 port also uses the C parser and there are some FOTDs that don't render right there as well. I have gone over the C parser code at one time attempting to find something offensive that would lead to the difference, but I didn't spot any obvious errors in all my reviews. I'm not an x86 assembly guru, so I haven't really studied the x86 assembly parser code and attempted to correlate it to the C code. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
