The Animated Triangle (Pilot's POV)
More SCIENCE!
This is a presentation of a hypothetical range of possible triangular inside loops of varying corner radii.
This time, we're looking at the triangular loop directly from the pilot's point of view. This was done in VideoF2B by moving the flight hemisphere's center to the exact point where it thinks the camera is located.
The presented example uses a typical modern flight radius of 22 meters (about 72 feet).
Note how the triangle degenerates into the simple inside loop when the corner radius reaches a certain magnitude. For this example, that's a radius of about 8.4 meters. It does not make sense to draw the triangle beyond that radius, so this animation then "deflates" the loop back down to the triangle :)
Ignore some of the goofy-looking reference lines. The drawing algorithm is very naive. It doesn't clip geometry behind the camera because, well, normally we don't move the sphere to these extremes.

Cones betwixt two abysses

Solution of a known cone tangent to two arbitrary planes at once. The only constraint is that the vertex of the cone must lie on the intersection line between the planes. Big thanks are due to Professor Sonja Gorjanc from the University of Zagreb for helping me figure out this solution. www.grad.hr/geomteh3d/radne_eng.html
It was triangle, then it become a circle
amazing technology!
