Public Members

PxU64 tempBufferCapacity

Initial capacity of temp solver buffer allocated in pinned host memory. This buffer will grow if more memory is needed than specified here.

PxU32 maxRigidContactCount

Size of contact stream buffer allocated in pinned host memory. This is double-buffered so total allocation size = 2* contactStreamCapacity * sizeof(PxContact).

PxU32 maxRigidPatchCount

Size of the contact patch stream buffer allocated in pinned host memory. This is double-buffered so total allocation size = 2 * patchStreamCapacity * sizeof(PxContactPatch).

PxU32 heapCapacity

Initial capacity of the GPU and pinned host memory heaps. Additional memory will be allocated if more memory is required.

PxU32 foundLostPairsCapacity

Capacity of found and lost buffers allocated in GPU global memory. This is used for the found/lost pair reports in the BP.

PxU32 foundLostAggregatePairsCapacity

Capacity of found and lost buffers in aggregate system allocated in GPU global memory. This is used for the found/lost pair reports in AABB manager.

PxU32 totalAggregatePairsCapacity

Capacity of aggregate pair buffer allocated in GPU global memory.

PxU32 maxSoftBodyContacts

Capacity of softbody contact buffer allocated in GPU global memory.

PxU32 maxFemClothContacts

Capacity of femCloth contact buffer allocated in GPU global memory.

PxU32 maxParticleContacts

Capacity of particle contact buffer allocated in GPU global memory.

PxU32 collisionStackSize

Capacity of the collision stack buffer, used as scratch space during narrowphase collision detection.

PxU32 maxHairContacts

Capacity of hair system contact buffer allocated in GPU global memory.
