Background
While developing prototypes for future versions of the software, we have gathered some really a few great ideas from advanced instructors including Tom Simpson of PoolClinics, Jerry Briesath of ThePoolSchool and Ira Lee of HighRock Production. We feel some of the prototype modules can be greatly helpful to people so we are going to provide them to the public.

Cut-Angle Calculator will be the first installment. There are two other interactive modules coming by the end of year 2007.

Special Thanks

How to Use
You can drag either the cue ball, the object ball or the ghost object ball around to get an instant calculation of the cut angle, the parallel projected ghost ball overlap percentage and the extended aiming line/tangent line markings on the rail. You can also use arrow keys to have finer movements.

We will update the website link soon. See you all in Vegas this Thurs... :)

Enjoy!

Hi Wei,

Adding the cut angle calculators should be a nice enhancement to have.

It occurred to me that the Cuetable application might be a very instructive interactive tool for learning the Diamond system and how to apply it to kick shots. Would this be something of value that you could incorporate into the cuetable application?

Thanks,
Allen

Thanks for the kind words, indeed we are doing something towards that direction.

We are looking to get educators and instructors involved in making more educational interactive modules for people.
 
Dear friends:

Thanks for your kind emails. Here are some goals for this project:

To Help Billiard Education
Fellow billiard instructors and players can use this free tool to visualize shots and to encourage further aiming studies.

To Bring Billiards into Education
High school students can use this fun teaching aid when they are learning trigonometry. We would like to invite high school teachers and associated educators to work on lesson plan ideas. Together we can bring pool back to school and get more younger minds interested in our sport.

For those who are at BCA and interested in setting up a group brainstorming session all together. I can be found around the CueTech room on May 17 and 18 around noon time.
 
When the first Wei Table came out, several years ago, it was a great boon to the pool forums, and has continued to help posters diagram shots that they have trouble with, or saw someone make, and wonder how to perform themselves. Now, the addition of Cue Table Public Library creates a splendid opportunity to use this at all levels of play. I encourage every poster here to learn to use this "easy-to-use" tool, and pass it along to everyone you know.

margin of error calculator

Wei, I was just fiddling around with the cut-angle calculator. It surely is nifty tool.

I think you can add much more to this tool without much additional overhead. Since you're already measuring and displaying the distance between the ghost ball and CB, you can use this measurement and a bit of extra computation to display the "margin of error" (in degrees off the CB aimline, green line in your figure) allowable to pot the ball in a standard 4.5'' pocket (the pocket being represented by the ghost object ball in your tools). You also would need the distance between the OB and pocket to do this calculation, but I'm assuming that would be easy to do since you already have a tool to meausure the distance between the ghost ball and the CB.

You can display the margin of error number right below the CB/GCB distance. It'll give the user an idea exactly how "geometrically tough" a shot is compared to other shots. The formula to obtain the margin of error is fairly easy to derive, and I used it to start this thread...

Let me know what you think, or if you need help.

Your tools are awesome!

Thank you JSP, the current module is actually a "simplified" version of what I have. We did that to help people understand the basic idea clearly.

Your idea is a great one. It has be brought up by Jude and David Maurer (of AcCueShot™) before. Maybe we can all design a improved interface together to make this a intuitive and useful tool

I am right outside of Zion Canyon now getting ready to assemble my BikeFriday together. Maybe the rock formation can bring some good ideas to my head :)

Thanks again for the kind words and great suggestion, please keep them coming. Also, if anyone needs graphics or resources in making public educational tools, please feel free to contact me. I will try my best to help :)

This is extremely cool. I know a lot of work must have gone into it and best of luck with any additional tweaking you might add. I've been playing with it (the cuetable!) for hours. :D
