PxDefaultSimulationFilterShader

Defined in include/extensions/PxDefaultSimulationFilterShader.h

PxFilterFlags PxDefaultSimulationFilterShader(PxFilterObjectAttributes attributes0, PxFilterData filterData0, PxFilterObjectAttributes attributes1, PxFilterData filterData1, PxPairFlags &pairFlags, const void *constantBlock, PxU32 constantBlockSize)

Implementation of a simple filter shader that emulates PhysX 2.8.x filtering.

This shader provides the following logic:

If one of the two filter objects is a trigger, the pair is acccepted and PxPairFlag::eTRIGGER_DEFAULT will be used for trigger reports
Else, if the filter mask logic (see further below) discards the pair it will be suppressed (PxFilterFlag::eSUPPRESS)
Else, the pair gets accepted and collision response gets enabled (PxPairFlag::eCONTACT_DEFAULT)

Filter mask logic: Given the two PxFilterData structures fd0 and fd1 of two collision objects, the pair passes the filter if the following conditions are met:

1) Collision groups of the pair are enabled
2) Collision filtering equation is satisfied
