Makes me wonder how they raytraced insane scenes in days of yore...
different computing paradigm, I suppose?  '80s Cray vs. 2004 AMD/Intel
is more apples 'n' oranges than '80s Intel vs. 2004 AMD/Intel; the
'80s Cray is still 'more powerful' than today's consumer machines I
guess.

Yeah, where's my 100 gb sticks of RAM?  :P

What about the epsilon value? Will this version be able to do a

How deep will it be able to zoom into mandelbrot patterns?

And would a Linux portation of this code run with 2.6 kernel?

It hasn't changed as the floating-point precision remains the same.

the current official unix source release builds and runs OK on an AMD64
gentoo 2.6.3 system.

  A 64-bit CPU has 64-bit long integers and 64-bit pointers. That's about it.

  The FPU has basically nothing to do with the CPU. It's practically its
own independent microprocessor. The bitness of the CPU has no effect
whatsoever on the FPU.
  The 'double' type floating point numbers in practically all computers
has always been 64 bits long and this hasn't changed in any way.

  The only advantage you will get from a 64-bit binary is that you will
be able to use scenes which use more than 4 gigabytes of memory. (With
the AMD64 processor there's also a slight speed advantage due to the
features the processor supports and which the compiler can use to
optimize the binary for speed.)

  (Another theoretical advantage of a 64-bit system is that your scene
files can be larger than 4 gigabytes, as well as the result image,
although this is quite improbable in practice (a 4GB raw image would
have a resolution of about 43600x32700).)

I have Windows XP and an AMD Athlon 64.  But when I try to install it, it
says I have the wrong processor type.  Do I have to "set" something yet or
what?  And how do you install an *.msi file anyhow?!

First you need the *64-bit version* of Windows XP, called Windows XP
Professional x64, which you can download for free at:

https://microsoft.order-9.com/winxp64/product.asp?catalog%5Fname=MSTrialandEval&category%5Fname=winxp64&product%5Fid=winxp64&id=dl

The 64-bit version is currently a time-limited trial and hasn't been
released as a final version for purchase.

Once you're running Windows XP Pro x64, then you will be able to install the
64-bit version of POV-Ray for Windows.  Installing a .msi should be as
simple as double-clicking on it - a .msi is a "Windows Installer" file.

You need to create a dual boot system. You can download an evaluation
version of the 64 bit XP from M$. I'm sure you know that you should
install separate OS on different drives. My laptop has only one HD so
I had to partition it into 2.
