A on C discs

Med
Lrg

Description :

A on C. Discs drawn in order round the base circle and with
the last placed disc on top.
The points mark the other side of the envelope circles across
a diameter from point A (the cusp of the curve)





A outside C discs

Description :

A outside C. Discs drawn in order round the base circle and with
the last placed disc on top.
The points mark the other side of the envelope circles across
a diameter from point A (the cusp of the curve)





A in C discs

Description :

A in C. Discs drawn in order round the base circle and with
the last placed disc on top.
The curve has in interior loop hidden by the solid elements.
The points mark the other side of the envelope circles across
a diameter from point A (the cusp of the curve)

Description :

A on C. Discs drawn in order round the base circle and with

Description :

A on C. Equal height cones.
The tips of the cones mark the centres of the envelope circles
and hence the base circle C.

A outside C. Equal height cones.
The tips of the cones mark the centres of the envelope circles
and hence the base circle C.

Description :

A on C. Rings drawn in order round the base circle and with
the last placed ring on top.

Description :

A in C. Rings drawn in order round the base circle and with

The interior loop of the curve is visble in this image as the circle
elements are just the outlines of the circles, rather than solid.
