Xfractint boundary tracing
by Jonathan Osuch 18 Jun '03

Tim, Do you have any recollection of any platform differences that would cause problems with enumerated data types? The Xfractint boundary tracing ends up in an infinite loop (actually there are several different loops) because the coming_from variable (of enumerated type direction) is ending up with values that are out of the bounds of the type.

Virtual video test results
by Tim Wegner 10 May '03

Jonathan asked: > Any results? HP-Pavilion with NVIDIA Vanta This works OK with virtual=no, but with virtual=yes, even non-virtual SVGA modes have problems going back to text. Something as simple as SF4 ESC gives a scrambled screen. BTW, it is possible that the virtual feature works, but since it messes up the text screens, I have no way to set it up to try it. I'm inclined to think that the virtual windows parameters should be settable even if the current mode is not a virtual mode. There could be words on the screen to the effect that these parameters only take effect in virtual mode. Dell Optiplex with ATI 3D Rage Pro - virtual screen modes works fine. Sony VAIO laptop with Rage Mobility 1 M AGP - works fine. Old no-name 120 Mhz Pentium with Diamond VIPER V550. Same behavior as HP - OK with virtual=no, scrambled screen otherwise. Summary. ATI video boards are OK, but Nvidia boards have problems. I believe the Diamond viper uses an Nvidia chipset. Since virtual=no works OK, I suggest you release this patch and let our loyal public help tabulate what works and what doesn't. We'll get more feedback that way. Or at least, move the proposed patched version to a public area. Tim

passes=2 in float-only Xfractint

Tim, Somewhere in the conversion to the float-only code we managed to fix passes=2. I've run the classic and float-only Xfractint code through indent. How do you want to distribute the source? Jonathan

Float-only Xfractint assembly version julia is broken
by Jonathan Osuch 13 Apr '03

Tin, The assembly version of the julia code in the float-only source is broken due to hard coded fractal types (sheesh!). It's fixed in mine. Jonathan

Time to run source through indent?

Tim, Before I start on anything, how do we want to handle running the source through indent? Jonathan
