What ho
Here's a first try at trefoil bombardment. Because the dispacement macro
returns a vector, I can add several together to produce multiple impacts.
Implementing the displacements in the trefoil program was a little fiddly
because I had to call it for the bricks, steps, step sideboards, handrail
posts and handrails separately. Somewhat arbitrarily, I've used thin
semitransparent beams to show the impact axis, and they've turned out
rather well - they look like some kind of projected beam weapon!
This is a scaled-down version from a 1600x1200 image (~900k), which can be
viewed at:
http://www.infradead.org/~wmp/trefoil_pow.jpg
The large image took ~1.5 hours to render, over half of which was parsing. I
reckon I could streamline my code a bit to improve that - I think I might
be doing some unnecessary calculation / variable declaration somewhere. I
also need to put a cutoff radius in the displace macro - you can just see
that the stairs in shadow on the column which threads the lower-right loop
have been perturbed by the beam where it passes close.
Cool, eh?

Very cool. What happens when the bullet paths intersect?

No problem, it's the projectile's shockwave.

Very much so!
If only the background... err... don't know but in a way
it could be more mysterious. Maybe foggier, or darker?
Looks a bit flat the way it is.

That is such a cool knot-thing, so why are we all so excited to see it get
bombarded? Don't know, but it is really impressive. It begs for an entire
science-fiction/fantasy story. The medieval floating knot-fortress zapped
by the invaders, killing young prince Somebody's family. Now he must get
revenge on the technologically superior aliens, armed only with whatever
magic made the knot float in the first place....I suppose he should have a
winged-horse sidekick and a gorgeous babe girlfriend, too.
Nice, nice work.

Awesome. Simply Awesome!
Keep up that bombardment!

I can't be the only one looking at the last two threads and thinking .oO

I thought they looked like vapour trails left by a projectile. Yes very
cool.
