Hello, I'm wondering if anyone can tell me where these formulas for RA and RP (apoapsis and periapsis) come from.
RA = \frac{a(1-e^{2})}{(1-e^{2}sin^{2}(LatB))^{3/2}}
RP = \frac{a}{(1-e^{2}sin^{2}(LatB))^{1/2}}
If you multiply RA by \frac{1-e^{2}sin^{2}(LatB)}{1-e^{2}}, you can get RP...
Hello,
I have a few dozen nodes spaced in a helix shape and an object trying its best to follow the path of the nodes. The nodes are like pylons/cones on the road, and the object is the car trying to navigate and follow them. The helix isn't perfect, so I am thinking to use a spline curve to...
