Developer Insights #9 – Orbit Tessellation – Kerbal Space Program
start and end parameters (shown here in degrees) affects the position and length of the curve and the more points we generate the better the lines match the ideal curve. Drawing an Orbit Let’s assume that we have the following: A parametric equation of our orbit. The exact equation is outside the scope of this post, but for those curious, you can see better results if it uses the eccentric anomaly as its parameter. A start and an end parameter that we’ll step between. A full orbit’s parametric equation generally ranges from 0 to 2π radians, or 0 to 360 degrees.
