CueTable Diamond System Calculator

[cuetable]

For those who might be interested in this subject, here is a new program I just wrote over the past few weeks. It can be used for both pool and billiard games. For more information you can find the instruction on the same page

Goodness! Is there anything you can't do???!!!

LOL shhhhh the APA coaches will now be bringing laptops with wyfy to league night.

Nice job on this to the maker. :smile:

 

[MilwShooter]

it does glitch out if you change the bank to the long rail (Now that I've been playing with it for a little bit). Is this something that you're still toying around with?

 

[Vinnie]

What do the gray numbers in parentheses represent?

 

[Sam Waltz]

App it ASAP pretty please!

I'd love to have this as an iPhone App! :thumbup:
Sweet deal man, very nicely done!

 

[OrigZaphod]

Very Nice!

I'd love to that only for the regular diamond system and banks...

Verry nice calculator. Why did you do this calculator with 2 tips of running english. That seems like a lot of english on the cue. Can the calculator be made to not have as much running enblish or no english at all
Thanks

Apple's safari doesn't support shockwave, which is needed to display cuetable properly. Otherwise, cuetable could become an instant popular iphone/ipod app.

I may be wrong but I think electronic devices like IPOD and smart phone are already illegal. (for many tournaments)

That's right. You are Wei Too Extreme!
Before you know it, you will have cuetable set up so all you have to do is setup the balls on the table and ask it to tell you what is the best pattern to use and what your pre-shot routine should be. :thumbup:

Nice work as always Wei!

That's a nice first start, Wei!

One essential thing you'll need to do to make it more accurate is handle track shifts between the 3rd and 4th rail as the cue ball origin moves away from the corner. See Byrne's or Caudron's books (among many others) for different ways of estimating this.

Unfortunately, by starting to add information like that explicitly and trying to match it to actual tables, you'll run into the problems/weaknesses that are inherent in these kinds of systems in general. They aren't derived from physics models, but are empirical approximations that only work under specific circumstances (i.e. the ball/cushion efficiencies, rail/ball/table friction coefficiences, etc, that they were designed on). That's why the books don't agree on how best to do it - the authors' tables are all different

Good luck!
Robert

p.s. You could also add some curving after each cushion, since the ball path *always* curves after cushions unless it is sliding into the rail with no followor draw at contact.

 

[Robert Raiford]

Actually, now that I look at it closer I see that you are accounting for *some* of the shifts. I was looking at long rail cue ball origins when making the previous comment.

Specifically, you are not changing the 3rd-4th rail tracks when the cue ball origin is anywhere on the long rail when the 3rd rail target is less than say 50.

For example, 70-35 goes to 35 on both the 3rd and 4th rail, when on a 'true' table it is much more likely to go to 40 on the 4th rail (i.e. around +1/2-diamond offset). You might score points with a carom like that, but your banking will really suffer if you don't correct. There are similar discrepancies in those 3rd rail ranges.

Safari does support shockwave, just not the iPhone version. Reguardless, it could still be made as an iPhone app which wouldn't even use safari. Man.... I would pay A LOT for cuetable apps.

I can't wait to play with this!!!

Very nice Wei! Keep it up man!!

 

[cuetable]

Thanks everyone for the kind words on this long overdue project I have for several years. There are still a lot to be done but I just don't have enough time and resource for it. Eventually I would love to bring 3 additional systems to this. For any discussion about this software, please post to cuetable.com so we can keep all the useful ideas together.

Rob, if you have some spare time, shoot me an email.

What do the gray numbers in parentheses represent?

when the starting point - aiming point < 50
gray number show 3rd rail offset

when the starting point - aiming point > 50
gray number show 4th rail offset

You can further adjust the offset by changing the blue number. Attached is what I have found on table 11 in Amsterdam Billiards Club in New York (-10 and -15)
