PxVec3 mPeriod: Size of the unit cell for periodic boundary conditions. If 0, the size of the simulation domain is specified by the mGridSize * mParticleContactDistance.

PxU32 mGridSizeX: Size of the x-dimension of the background simulation grid. Translates to an absolute size of mGridSizeX * mParticleContactDistance.

PxU32 mGridSizeY: Size of the y-dimension of the background simulation grid. Translates to an absolute size of mGridSizeY * mParticleContactDistance.

PxU32 mGridSizeZ: Size of the z-dimension of the background simulation grid. Translates to an absolute size of mGridSizeZ * mParticleContactDistance.

PxReal mParticleContactDistance: Two particles start interacting if their distance is lower than mParticleContactDistance.

PxReal mParticleContactDistanceInv: 1.f / mParticleContactDistance.

PxReal mParticleContactDistanceSq: mParticleContactDistance * mParticleContactDistance.

PxU32 mNumParticles: The number of particles in this particle system.

PxU32 mMaxParticles: The maximum number of particles that can be simulated in this particle system.

PxU32 mMaxNeighborhood: The maximum number of particles considered when computing neighborhood based particle interactions.

PxU32 mMaxDiffuseParticles: The maximum number of diffuse particles that can be simulated using this particle system.
