TP Zoom Functions

ZOOM Functionalities of TP

Mouse Button 2 , right Mouse button

Using Mouse Button 2 (MB2) one can indicate on a trackplot a zoom window of an area which one likes to see enlarged.

In this example the pilot got scored to the SS, 1st TP , says the program.

Using the MB2 , means Move mouse into one corner of the area you want to zoom, press MB2, keep button pressed and move Mouse, release MB2
and you got a little window which will now get displayed enlarged.
The code calculates the the center of this window as the new center reference.
And takes the average of height and width to make a new square window.

Within the MB2 ZOOM window one can do another MB2 ZOOM again and zoom in further

It shows that the recorded track point was outside of the circle.
The MB2 Zoom Window got a an option to show time stamps or not.
And display a 10 meter grid.
First one clicks any of the options either on or off. Then click the redraw button .

Dynamic distance measurement to cursor position

One can also activate a Distance measurement, which wil show a list of turnpoints as reference points.
Select, make blue, one of them and the Distance text will then be replaced a by changing value. Which gives the cursor distance to that reference point in km.

Shift MB1 scores pilot to cursor position

Designed for those tracks where a pilot walks after landing closer to the next turnpoint or goal.

Activate dynamic cursor distance measuring.
Place cursor to where you reckon pilot landed.
Shift MB1 then takes this position and creates a new score that can then be accepted.
Ok, the new score does not really make it all the way to the XML bulk output.
Recommend you write down the new score and fix up the score in RACE by hand.
And everytime you run a Auto Redo, the pilot will get his original score back in the XML.
Use the Problem button to report and log the troublemaker.

One Step back Zoom function

Using MB1, left Mouse Button, resets the Zoom to the previous Zoom Window. Only one step back is possible.

Closing ZOOM window by Double Click MB1

Double Click on MB1 closes the window, that works for most windows. But not the main TP window.

Fixed Zoom windows

In the trackplot window one has got in the upper right corner a choice of TakeOff, Start of Speed Section SS, Tunrpoints and Goal area to be zoomed into.

The preprepared Zoom window offers more options.

Marked waypoints can be used to validate visually if a pilot can claim a turnpoint.

The program chooses waypoints which got created at the task date and displays them. Using the comment info from the GPS. Waypoints from eMap and eTrex do not have a comment section and can not be used. The Waypoints date and time info is displayed in a separate window. The time is in Zulu, add 2 hours for South Africa.

It up to the organizers/task committee to decide if the waypoint gets accepted.

Here we have a pilot who missed Starttarp.
The track goes red after Starttarp. Indicating that Starttarp was not accepted.

Zoom without any display options shows that he missed

Switch on the Option to display any possible turns in between track points. Turn radius is driven by the average speed in km/h of the Paraglider.
Use 20 to 30 km/h at speed
Program checks if pilot would have managed to fly a circle between 2 track points.
And displays possible solutions.
It is up to the scoring team to accept visually a possible valid turnpoint.
Program can not determine if any of the circles is acceptable

No luck here.

Let's look at interpolated points in between the track points.
The interpolated points are calculated by using the previous direction and speed and the next track point and trying to find a point in between.
