Introduction

This is a simple simulation software which teaches how to aim at a ball when playing pool.

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.

Once you are familiar with all the basic functions, you can use the software in full-sized version for better viewing.

Illustrations

 

Object Ball (OB)
 Ghost Object Ball (GOB)

Object Ball Travel Line

The ball you are aiming at. The imaginary ball position you want the object ball to go to The imaginary line that goes through the center of OB and GOB
Cue Ball (CB)
 Ghost Cue Ball (GCB)
 Aiming Line
The ball you are using to hit the target The imaginary ball position that is 1 ball width away from the OB and at the exact opposite direction of GOB. The imaginary line that goes through the center of CB and GCB
Grid Line
 Symbol On/Off
 Tangent Line
Lines conneting each diamonds along the rails of the table. There are also markings along the rail for 1/10 diamonds measurements You can toggle on/off any balls and lines for better display. The imaginary line drawn from the contact point that's perpendicular to the line connecting the centers of CB and OB
Cut-Angle
 GCB/OB Overlap Percentage
 CB/GCB Distance
The angle formed by the Aiming Line and OB Travel Line. Please note we didn't set a limit for angles greater than 90 degrees. The percentage of overlap on OB from the frontal parallel projection of GCB. The distance between the center of CB to GCB in inches based on a 9 foot regulation pool table.

Calculation

 

Projected Ghost Cue Ball

Frontal isometric projected view of the imaginary cue ball based on the Cut-Angle.

For measuring purpose, each ring inside marks 1/8 ball and each notch along the top edge marks 30 degrees.

The red cross shows the exact contact point between CB and OB.

Please note there is no vanishing point in this parallel perspective view and it does not exist in real life.

Special Thanks

While developing prototypes for future versions of CueTable, we have gathered some really a few great ideas from advanced instructors including:

Tom Simpson - PoolClinics
Jerry Briesath - ThePoolSchool
Joe Tucker - The Third Eye Trainer
Ira Lee - HighRock Production
Tony Robles - Tony Robles Pool School

We feel some of the prototype modules can be greatly helpful to people so we are going to provide them to the public.

Project goals

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.

This is our small token to help to the public education of pool and billiard. Please feel free to contact us if you have any good ideas in making this applet even more useful for people.
