depicted with perspective projection viewer distance from center: 10r
line distancd: 10°
line width: 2°
axial tilt: 37.5°
rotation: 7.5°
base color: #22326b
plotted with several adapted cubic bezier-curves
The plotcurves were calculated by some fancy python code. The bezier-curve
controlpoints are placed on tangents of the function-curve. They are
furthermore positioned in a way to minimize the average quadratic distance
between the bezier-curve and the function. This gives an accuracy, so that
the deviation is in no point greater than 0.00001.
