There is a link to a POV patch (over v2.2) that does this in
http://povray.org/links/3D_Programs/POV-Ray_Unofficial_Patches_and_Front_End_Programs/POV-Ray_Patches_v2_2/

Ooooh... sounds like fun. :-) (Yes, I've seen the animations from the
renderer that already does this.)

Actually, this shouldn't be too far off as a MegaPov feature. (of course,
post-3.5)

My favorite by far. Anybody want to volunteer to write this patch?

I already know why it won't be implemented, you notice there was an evil

Free and easy! Just change some jumpers on the motherboard... :)

BTW, this FAQ also talks about non-uniform transformations, saying they are only
possible in mesh modellers by moving the vertexes. Indded they are quite
possible in MegaPOV isosurfaces.

Firstly: You can't modify an arbitrary object with an isosurface.
Secondly: Yes, you can modify an isosurface function with another function.
But is this really a transformation? When you modify a function with another
function, you just create a third function. There are no specific
transformations involved.
Yes, you can, for example, convert a cylinder-shaped isosurface into a
cone-shaped isosurface. This is, however, done by actually creating another
function, not by transforming.
Of course it is possible to think that any transformations are possible
for an isosurface if you like.

I think that if you try to make your computer 5 times faster by overclocking
(and notice that it's not enough to se the MHz amount 5 times larger for
this), you will fry your CPU.

For the user, yes. Doesn't cost the POV-Team a dime.

That depends on where you started. If I'd started with my K6/233 at 50 MHz,
then decided to overclock to five times that, it'd probably work (but it'd
run hot... my K6 is the last .35u K6 made, for just that reason.)

Ok, I will have to expand the requirements: full simulation of frequency
shifting(Doppler effect), taking gravitational effects into account, etc.
