\brief This overall visualization scale gets multiplied with the individual scales. Setting to zero turns ignores all visualizations. Default is 0.  The below settings permit the debug visualization of various simulation properties. The setting is either zero, in which case the property is not drawn. Otherwise it is a scaling factor that determines the size of the visualization widgets. Only bodies and joints for which visualization is turned on using setFlag(VISUALIZE) are visualized. Contacts are visualized if they involve a body which is being visualized. Default is 0. Notes: to see any visualization, you have to set NX_VISUALIZATION_SCALE to nonzero first. the scale factor has been introduced because it's difficult (if not impossible) to come up with a good scale for 3D vectors. Normals are normalized and their length is always 1. But it doesn't mean we should render a line of length 1. Depending on your objects/scene, this might be completely invisible or extremely huge. That's why the scale factor is here, to let you tune the length until it's ok in your scene. however, things like collision shapes aren't ambiguous. They are clearly defined for example by the triangles & polygons themselves, and there's no point in scaling that. So the visualization widgets are only scaled when it makes sense. Range: [0, inf) Default: 0

The two directions are: uAxis = (dirOfAnisotropyWS ^ contactNormal).normalize() vAxis = contactNormal ^ uAxis This way [uAxis, contactNormal, vAxis] forms a basis. It may happen, however, that (dirOfAnisotropyWS | contactNormal).magnitude() == 1 and then (dirOfAnisotropyWS ^ contactNormal) has zero length.

\brief The difference between 'normal' and 'strong' friction is that the strong friction feature remembers the 'friction error' between simulation steps. The friction is a force trying to hold objects in place (or slow them down) and this is handled in the solver. But since the solver is only an approximation, the result of the friction calculation can include a small 'error' - e.g. a box resting on a slope should not move at all if the static friction is in action, but could slowly glide down the slope because of a small friction error in each simulation step. The strong friction counter-acts this by remembering the small error and taking it to account during the next simulation step. However, in some cases the strong friction could cause problems, and this is why it is possible to disable the strong friction feature by setting this flag. One example is raycast vehicles, that are sliding fast across the surface, but still need a precise steering behavior. It may be a goodidea to reenable the strong friction when objects are coming to a rest, to prevent them from slowly creeping down inclines. Note: This flag only has an effect if the NX_MF_DISABLE_FRICTION bit is 0.
