Re: Calibration plot

Hi.

As you see from the graph in the middle of the egg the “aspect ratio” is 1.5. The circles have to be ‘elongated’ 150% in order to plot as round circles on the egg. See this post as well.

Here are the text output of the plotted data;

Pen Radius; 31.50
Egg radius = 21.00
Egg length = 58.00

At egg max diameter;
Step length pen = 0.99
Step length egg = 0.66
Aspect ratio = 1.50

L=  0.01, Inkscape y value=   0.00, aspect ratio= 6.462
L=  3.75, Inkscape y value=  50.00, aspect ratio= 3.481
L=  7.50, Inkscape y value= 100.00, aspect ratio= 2.445
L= 11.25, Inkscape y value= 150.00, aspect ratio= 2.036
L= 15.00, Inkscape y value= 200.00, aspect ratio= 1.807
L= 18.75, Inkscape y value= 250.00, aspect ratio= 1.655
L= 22.50, Inkscape y value= 300.00, aspect ratio= 1.566
L= 26.25, Inkscape y value= 350.00, aspect ratio= 1.523
L= 30.00, Inkscape y value= 400.00, aspect ratio= 1.507
