Apollonius

Apollonian gasket drawing

Here are three ways to draw an apollonian gasket! If you have a mouse, drag the centers of three circles around. Or, keeping the outer circle fixed, drag two mutually tangent inner circles. You can also specify three bends to generate a gasket which contains those three bends tangent to one another. You can adjust the presentation of the circles, including an indicator of the bend. If you prefer to draw the circles yourself, you can also download a csv list of the circles.

Style Width px. Firefox can't reliably draw more than 10,800px.

Labels This feature seems to only really work on Firefox right now. Inkscape does not support the feature "transform-origin" yet, so it can't render the labels in the correct spots. Edge (and probably Chrome) does something I don't understand.
