 Extract filter object type from the filter attributes of a collision pair object.

 Enables the usage of the articulations feature. This function is called automatically inside PxCreatePhysics(). On resource constrained platforms, it is possible to call PxCreateBasePhysics() and then NOT call this function to save on code memory if your application does not use articulations. In this case the linker should strip out the relevant implementation code from the library. If you need to use articulations but not some other optional component, you shoud call PxCreateBasePhysics() followed by this call.

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

Filter shader to specify handling of collision pairs.

Collision filtering is a mechanism to specify how a pair of potentially colliding objects should be processed by the simulation. A pair of objects is potentially colliding if the bounding volumes of the two objects overlap. In short, a collision filter decides whether a collision pair should get processed, temporarily ignored or discarded. If a collision pair should get processed, the filter can additionally specify how it should get processed, for instance, whether contacts should get resolved, which callbacks should get invoked or which reports should be sent etc.

Note:
A default implementation of a filter shader is provided in the PhysX extensions library, see PxDefaultSimulationFilterShader.
See also:
PxSceneDesc.filterShader PxSimulationFilterCallback Filter method to specify how a pair of potentially colliding objects should be processed.Return the PxFilterFlag flags and set the PxPairFlag flags to define what the simulation should do with the given collision pair.
This methods gets called when:
  • The bounding volumes of two objects start to overlap.
  • The bounding volumes of two objects overlap and the filter data or filter attributes of one of the objects changed
  • A re-filtering was forced through resetFiltering() (see PxScene::resetFiltering())
  • Filtering is requested in scene queries
Note:
Certain pairs of objects are always ignored and this method does not get called. This is the case for the following pairs:
  • Pair of static rigid actors
  • A static rigid actor and a kinematic actor (unless one is a trigger or if explicitly enabled through PxSceneFlag::eENABLE_KINEMATIC_STATIC_PAIRS)
  • Two kinematic actors (unless one is a trigger or if explicitly enabled through PxSceneFlag::eENABLE_KINEMATIC_PAIRS)
  • Pair of particle systems
  • Two jointed rigid bodies and the joint was defined to disable collision
  • Two articulation links if connected through an articulation joint
  • Cloth objects and rigid body actors
Note:
This is a performance critical method and should be stateless. You should neither access external objects from within this method nor should you call external methods that are not inlined. If you need a more complex logic to filter a collision pair then use the filter callback mechanism for this pair (see PxSimulationFilterCallback, PxFilterFlag::eCALLBACK, PxFilterFlag::eNOTIFY).
Parameters:
[in] attributes0 The filter attribute of the first object
[in] filterData0 The custom filter data of the first object
[in] attributes1 The filter attribute of the second object
[in] filterData1 The custom filter data of the second object
[out] pairFlags Flags giving additional information on how an accepted pair should get processed
[in] constantBlock The constant global filter data (see PxSceneDesc.filterShaderData)
[in] constantBlockSize Size of the global filter data (see PxSceneDesc.filterShaderDataSize)
Returns:
Filter flags defining whether the pair should be discarded, temporarily ignored, processed and whether the filter callback should get invoked for this pair.

PX_INLINE void PxContactPair::bufferContacts ( PxContactPair newPair,
PxU8 *  bufferMemory 
) const [inherited]

Helper method to clone the contact pair and copy the contact data stream into a user buffer.

The contact data stream is only accessible during the contact report callback. This helper function provides copy functionality to buffer the contact stream information such that it can get accessed at a later stage.

Parameters:
[out] newPair The contact pair info will get copied to this instance. The contact data stream pointer of the copy will be redirected to the provided user buffer. Use NULL to skip the contact pair copy operation.
[out] bufferMemory Memory block to store the contact data stream to. At most requiredBufferSize bytes will get written to the buffer.

) [inherited]

Construct a batch query with specified maximum number of queries per batch.

If the number of raycasts/sweeps/overlaps per execute exceeds the limit, the query will be discarded with a warning.

Parameters:
maxRaycastsPerExecute Maximum number of raycast() calls allowed before execute() call. This has to match the amount of memory allocated for PxBatchQueryMemory::userRaycastResultBuffer.
maxSweepsPerExecute Maximum number of sweep() calls allowed before execute() call. This has to match the amount of memory allocated for PxBatchQueryMemory::userSweepResultBuffer.

const physx::PxTolerancesScale &  scale,
bool  trackOutstandingAllocations = false,

)

Creates an instance of the physics SDK with minimal additional components registered.

Creates an instance of this class. May not be a class member to avoid name mangling. Pass the constant PX_PHYSICS_VERSION as the argument. There may be only one instance of this class per process. Calling this method after an instance has been created already will result in an error message and NULL will be returned.

Parameters:
version Version number we are expecting(should be PX_PHYSICS_VERSION)
foundation Foundation instance (see PxFoundation)
scale values used to determine default tolerances for objects at creation time
trackOutstandingAllocations true if you want to track memory allocations so a debugger connection partway through your physics simulation will get an accurate map of everything that has been allocated so far. This could have a memory and performance impact on your simulation hence it defaults to off.
pvd When pvd points to a valid PxPvd instance (PhysX Visual Debugger), a connection to the specified PxPvd instance is created. If pvd is NULL no connection will be attempted.
Returns:
PxPhysics instance on success, NULL if operation failed

Creates an instance of the physics SDK.

Calling this method after an instance has been created already will result in an error message and NULL will be returned.

Calling this will register all optional code modules (Articulations, HeightFields, Cloth and Particles), preparing them for use. If you do not need some of these modules, consider calling PxCreateBasePhysics() instead and registering needed modules manually.

Variable Documentation

const PxU32 INVALID_FILTER_PAIR_INDEX = 0xffffffff [static]

A constraint.

A modifiable contact point. This has additional fields per-contact to permit modification by user.

Contact point data including face (feature) indices.

Header for contact patch where all points share same material and normal.

A constraint is expressed as a set of 1-dimensional constraint rows which define the required constraint on the objects' velocities.

Each constraint is either a hard constraint or a spring. We define the velocity at the constraint to be the quantity

v = body0vel.dot(lin0,ang0) - body1vel.dot(lin1, ang1)

For a hard constraint, the solver attempts to generate

1. a set of velocities for the objects which, when integrated, respect the constraint errors:

v + (geometricError / timestep) = velocityTarget

2. a set of velocities for the objects which respect the constraints:

v = velocityTarget

Hard constraints support restitution: if the impact velocity exceeds the bounce threshold, then the target velocity of the constraint will be set to restitution * -v

Alternatively, the solver can attempt to resolve the velocity constraint as an implicit spring:

F = stiffness * -geometricError + damping * (velocityTarget - v)

where F is the constraint force or acceleration. Springs are fully implicit: that is, the force or acceleration is a function of the position and velocity after the solve.

All constraints support limits on the minimum or maximum impulse applied.

Note:
Not all fields are currently exposed to the user.
