Hi folks.

I posted a still from this in povray.binaries.images yesterday... Well
anyway, I finally suceeded in finishing the actual animation. (Overnight
render, 6 hours 45 mins - 2 hours parsing + 4 3/4 hours rendering!)

When the first frame is rendered, POV-Ray sits there generating a 2MB
include file containing all the fractal data. (This is *not* included in the
time given above.) Once this file exists, it is reused for each frame (since
the fractal itself doesn't change during the animation).

I shrank the animation down to 320 x 240, but it's still a tad big -
2,335,026 bytes (ie, about 2MB). It can be found (hopefully!) at

http://www.btinternet.com/~Orphi/Video/Mandel-Flight-3-Small.m1v

(Assuming the people who host my website get their stuff right of course!!!)

I'm still not *quite* happy with the way it looks... the "particles" don't
look right at all, but the lighting is fairly good...

Comments?

Andrew.

Any chance of having the light sources fade out rather than cutting off 
abruptly?  Even if they only fade out over three or four frames, it 
could make it quite a bit easier to watch.

Yes, I've been thinking the same sort of thing myself... If I can figure the
math out, it might be worth doing. (It took me ages to get it like it is
now - and I still haven't managed to get the spread of particles right yet.
They are all "lined-up" too much. *sigh*)

Andrew.

for fading a light_source #declare a spline containing the colors to be
stepped through, then in your light source reference the spline with "(how
long particle has existed)/(lifespan)", the spline does all the rest.  Thus
if you do

#declare light = spline{
    linear_spline
    0.0, <1,1,1>
    1.0, <0,0,0>
}

the light will be dimmer the longer the particle exists.
