It is well known that the Cartesian equation for a general parabola in 2D space is $$(Ax+Cy)^2+Dx+Ey+F=0$$ or in parametric form, $$(at^2+bt+c, pt^2+qt+r)$$
- What is the Cartesian system of equations for a general parabola in 3D space?
- Is there a matrix representation?
- What is the parametric form?
- What is the aperture?
