Tiling with lines of constant thickness

[hshackle]

Hi! Thanks a lot for creating this package; I've found it very helpful. I have a question regarding the tiles.ipynb example. The thickness of the geodesic lines that are drawn vary with the distance from the boundary. Is there any way to modify this code so that the thickness is constant, or is this not easily doable with the current code?

This is possible.

hwidth sets the width of the line in hyperbolic space. This is why the thickness appears to vary when projected into the Poincare disk. You can simply draw the lines normally by replacing hwidth and fill with stroke_width, stroke, and fill='none'. Change

d.draw(tile, hwidth=0.02, fill='white')

into

d.draw(tile, stroke_width=0.02, stroke='white', fill='none')
