For effect only, some sort of mechanism, possibly magic, senses where all the balls are on the table and turns on an led under it bright enough to shine through the felt.
As a ball moves from that position, the led fades out over a second or two and as subsequent leds are activated and faded out
along the balls path an illuminated "tracer" effect is achieved for all the ball's trajectories.
Safer than dropping acid.

a "predicted path" would be good too, when you are lining up your pool/snooker cue - not sure how that would be achieved though. |
|
| |
Magic. (Or some kind of sensor in the pool cue's tip.) |
|
| |
I like this - it caused me to spawn one of my own. |
|
| |
I've seen slow motion footage of snooker, taken with a
heat-sensitive camera. It looked just like this would...

Ya know what? You could do a very simple version of this by having two layers of clear film with some kind of liquid between them that when disturbed changes color. You could do that by having a heavy and a light liquid of dark and light color respectively that when touched mixes up for a second before separating back to their density determined layers. |
|
| |
Or you could just have a dark viscous liquid that's pushed out of the way for a second as the ball passes over and have a bright light underneath that shines through the thinned bit until it closes up. |
|
| |
The thing about the lights though is you could have them sparkle, have different colors for the different balls, generally put on a pretty crazy lightshow. |
|
| |
And while you're at it sensing balls anyway, why not add sound effects? "bing" "Pow!" "BOOM!!!" Depending on how hard you hit them. You could also have riccochet sounds as well. |
|
| |
Yup, it would be pinball meets pool. |
|
| |
Or just play on a very large flatscreen. It could display any
image - green as a background; ball-traces; how-the-shot-
should -have-been-played, etc etc. |
|
| |
Instead of a regular plastic screen, you could have a softish
transparent
polymer to mimic the feel of baize. |
|
| |
Yea, you could basically play on a touchscreen and open up all kinds of possibilities. |
|
| |
For that matter you could despense with the real balls all together and just have a virtual pool table activated by sensing something in the tips of the cues. Having digitally created balls would allow you to do stuff like have them explode or.. ok, that's the only thing that comes to mind. |
|
| |
This would so very cool on the break. Fireworks,
almost! [+] |
|
| |
Use a normal video projector and a camera pointed at the table from above. If the zoom is carefully set, you should be able to minimize or eliminate the tunnel effect. |
|
| |
Each frame will be slightly behind real-time, and should self-mix with past frames giving a fade-away ball trail. |
|
| |
(OK, I just have to try this when I get home...) |
|
| |
No, that's the genius of it. Damn elegant. |
|
| |
Brilliant, [doc]! I give it two buns up! [+][+] |
|
| |
I get the real tracers without the acid.
Not quite fireworks off the break, but still cool. Being able to see tracers left by each ball teaches you trajectories at a gut level and made learning to play pool very easy. (+) |
|
| |
This would go great with the tone of a deep bell
being struck every time a ball hits the wall or
another ball. |
|
| |
//Each frame will be slightly behind real-time, and

|
| |
This sounds cool...except each recursive image gets
smaller and smaller...doesn't it? |
|
| |
No - not if the projector is set up to give a 1:1 image. It's a
very nice idea! |
|
| |
Similar effects were used on TV back in the ?70's? before
complex special effects were cheap. The effect was often
used in music videos, where the moving performer would be
followed by a trail of perhaps a dozen delayed and
progressively dimmer images. |
|
| |
Good thinking, [Freefall]. |
|
| |
As a side-effect, you should be able to dispense with the usual overhead lighting. The general effect is that each captured frame adds to the one before, eventually blowing out to full white at the cue ball. If the camera has auto white balance, it should cap the video level, resulting in an interesting contrast-enhanced lighting of the table. |
|
| |
JUST DO IT. Someone? Awesome idea. Thankfully the anno's
supplied some halfbaked how too's. |
|
| |
Kicking an old idea, but just saw something like this on Youtube. See link. |
|
| |
[Freefall] not quite how I imagined it. |
