struct PxFrictionType
Enum for selecting the friction algorithm used for simulation.
PxFrictionType::ePATCH selects the patch friction model which typically leads to the most stable results at low solver iteration counts and is also quite inexpensive, as it uses only up to four scalar solver constraints per pair of touching objects. The patch friction model is the same basic strong friction algorithm as PhysX 3.2 and before.
PxFrictionType::eTWO_DIRECTIONAL is identical to the one directional model, but it applies friction in both tangent directions simultaneously. This hurts convergence a bit so it requires more solver iterations, but is more accurate. Like the one directional model, it is applied at every contact point, which makes it potentially more expensive than patch friction for scenarios with many contact points.
PxFrictionType::eFRICTION_COUNT is the total numer of friction models supported by the SDK.
