This is still an incomplete version of Hyperbolic! You can play with it, but it's still oriented towards development and testing.

To run what is available right now, just launch draw.py.

You can rotate the hyperbolic plane (i.e., making an elliptic transformation) around a point just moving the mouse pointer to that point and scrolling the mouse wheel.

You can translate the hyperbolic plane (i.e., making a hyperbolic transformation) along a segment just clicking in one point and then releasing the mouse button in another.

There is so far no way to make parabolic transformations, although you can just replace them with elliptic transformations whose fixed point is very close to the border.

• Pressing key M you can switch between the Poincaré and Klein model for the hyperbolic plane.

So far it isn't possibile to do anything else...

Stay tuned!
