Detailed Description

enumeration that determines the way in which two material properties will be combined to yield a friction or restitution coefficient for a collision.

When two actors come in contact with each other, they each have materials with various coefficients, but we only need a single set of coefficients for the pair.

Physics doesn't have any inherent combinations because the coefficients are determined empirically on a case by case basis. However, simulating this with a pairwise lookup table is often impractical.

For this reason the following combine behaviors are available:

eAVERAGE eMIN eMULTIPLY eMAX

The effective combine mode for the pair is maximum(material0.combineMode, material1.combineMode).

Enum

enum PxCombineMode::Enum

Enumerator
eAVERAGE	Average: (a + b)/2.
eMIN	Minimum: minimum(a,b)
eMULTIPLY	Multiply: a*b.
eMAX	Maximum: maximum(a,b)
eN_VALUES	This is not a valid combine mode, it is a sentinel to denote the number of possible values. We assert that the variable's value is smaller than this.
ePAD_32	This is not a valid combine mode, it is to assure that the size of the enum type is big enough.
