Does anyone know how real track builders create constant radius corners when the ground is not flat? Usually a track is designed in top view (not just BTB, but CAD and other methods too). However if you take a circle and project it down onto a slope (imagine a perfect shadow), the resulting line will no longer be a perfect curve from the driver's point of view.
In top view this corner is perfectly circular:
But when projected onto a steep slope like this (imagine just moving a node downwards):
I think the driver's experience would be that the corner's radius changes:
So, should a track's top view be changed to take this effect into account?
