Jonathan,

As to your 3D pixel question, we'll hopefully get to that... but just a moment ago, in the Fractint 20.02.5 program file, I saw this icon named 'MAKEFCFG.EXE'. "Hmm... what's that do?" I wondered, even as I reflexively gave it a click... Suddenly a small dos screen opened, quickly closed and a file named "fractcfg.old" appeared in the folder.
No big thing, but as I then opened the program, I discovered that my choice of video modes is now severely constrained: F2 to F10 and SF1 to SF3 are my only remaining options. I deleted the .old file, but the former functionality has not returned. Any suggestions?


As to the original question, ideally a 3D pixel would allow us to write/render formulas such as

M3D {
Zrng = (-2,2)
a = Xpt(3Dpix), b = Ypt(3Dpix), c = Zpt(3Dpix)
x1 = y1 = z1 = 0:
x2 = x1^2 - y1^2 - z1^2 + a
y2 = 2*x1*y1 + b
z2 = 2*x1*z1 + c
x1 = x2, y1 = y2, z1 = z2
j = x1^2 + y1^2 + z1^2
j < 8 }

for objects such as 'http://ixitol.com/3DMset.GIF', which required the 40-odd lines of code in Gerald K. Dobiasovsky's 'Rot3d_T-set' formula.

Gerald's formula is innovative and ingenious, but ad hoc. A built-in 3D pixel would surely save rendering time and ultimately provide many more options for resolution, colors and so forth.

Of course, there are a lot of ramifications to this idea; but even the most basic implementation would be a good start, and it would be fun to see where it eventually leads...

Thanks for your consideration of this idea.

Russell
