Efficiently fill an ellipse with a k-many random ellipses
One way to get non-overlapping ellipses is to place their centers far enough apart that they don't overlap no matter how they are oriented: use HardcorePointProcess to determine the centers, within a ...

Conic sections: intersection of a plane and a cone. How can I change the equation of the plane to get conic sections automatically?
For any plane equation {a,b,c}.{x,y,z}=d, we use MeshFunction->Function[{x, y, z}, {a, b, c} . {x, y, z} - d and ...
