[TRAC-3575] Strange conic behavoir
I'm a new user and I haven't done much yet with Geogebra.
Recently I developed a "Clifford Torus" worksheet.
Well isn't that nice?
In the proces of building I learned a lot of many beautiful ascepts of Geogebra.
It's really a great tool but I discovered a strange behavior of some conics.
Try for example:
Conic c1: Is correct.
Conic c2: Correctness of this conic depends on the position of axes within the graphic window.
Conic c3: Always incorrect.
These exceptional cases seem to indicate that something is caused by internal rounding errors.
Perhaps this behavior of conics is well known and accepted.
In that case, sorry for bothering.
If someone is interested:
For the rebel die-hards who refused to surrender:
See attached worksheet that shows incorrectness of some conics
caused by small displacement of certain points.
Don't waste too much time. These are exceptional cases.
