===== Torus-shaped contact surface on next ===== | |||
On next as of 2022-3-19 one can specify a torus-shaped tyre contact surface using these new parameters: | |||
* '''wheel-radius''' (default 0) | |||
* '''tyre-radius''' (default 0) | |||
* '''wheel-axle-x''' | |||
* '''wheel-axle-y''' | |||
* '''wheel-axle-z''' | |||
The contact point will be the lowest point on a torus with radius '''tyre-radius''' wrapped around a wheel with radius '''wheel-radius''' centred on point '''(x, y, z)''' with orientation defined by '''wheel-axle'''. This contact point will depend on the aircraft's orientation relative to the ground. | |||
If not specified, '''wheel-axle''' defaults to (0, 1, 0), giving a conventional vertical wheel in line with the aircraft. Other values may allow modelling of, for example, a Bf109's non-vertical undercarriage. | |||
Default values of zero for wheel-radius and tyre-radius give a fixed contact point at (x, y, z) as before. | |||
