[Flightgear-devel] control surface normalization

2004-12-15 Thread Jon Berndt
Do 3D models use a "normalized" range to model aerosurface rotation, or actual degree magnitude? I've been looking at the JSBSim flight control code and the addition of the code that "normalizes" aerosurface (elevator, aileron, etc.) rotation positions confuses the code, and appears to only be r

I have a situation where I am getting an error and I am not sure why. I have a class MyClass that has a copy constructor. The class has a private member that is a const pointer (the pointer is constant - not what the pointer points to): class MyClass { public: MyClass(const MyClass &mc); // co
