Question on using "Hyperbolic Geometry in the Poincare Disk"

Beth Riggs shared this question 2 years ago
Needs Answer

I am attempting to use the custom tools in "Hyperbolic Geometry in the Poincare Disk". The author is "soundmanbrad."

I am either using the tools wrong or something isn't working in the file. For example, the "Hyperbolic Midpoint" tool... I cannot figure out how to get it to construct the midpoint of a hyperbolic line segment.

Can you help me?

Please contact the author of the resource for details about how they created the tools.

In the Details page of the app you are referring to, select "Contact author of resource" and add your message in the appearing input box.

If you post your file here, and describe your steps, maybe someone can help.

Hi, I've encontered some problems too with the available custom hyperbolic tools, especially with Hyperbolic circles, perpendiculars and midpoints; I worked around some of the issues and managed to build working tools for all points inside the unit circle; it's not a pretty solution but it works. Hope it helps!

Hallo, das Applet oben ist wieder ein Beispiel dafür, dass mit Verwendung von


benutzerdefinierten Werkzeugen (custom tools) die Deckkraft von Linien (opacity) nicht mehr


verändert werden kann!

Ein sehr nützliches Werkzeug in der hyperbolischen Ebene ist der Kreis des Apollonios:

Zu drei Punkten A,B,P gibt es genau einen Kreis durch P, zu dem A,B symmetrisch liegen!

Dazu: Möbiuswerkzeuge, die man leider nicht mehr wegen obiger Einschränkung

sinnvoll verwenden kann.

Gruss

W.F.
