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.
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. (It will be on the extended Object Ball Line)
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
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.
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.
Project 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.
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.
Join us
This is our small token tohelp 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.
"CueTable is cool, helpful
and a lot of fun. The graphics and capabilities are great and they
bring pool diagrams off the napkin and into the 21st century!"
