flags for configuring properties of the scene
| enum PxSceneFlag::Enum |
| Enumerator | |
|---|---|
| eENABLE_ACTIVE_ACTORS | Enable Active Actors Notification. This flag enables the Active Actor Notification feature for a scene. This feature defaults to disabled. When disabled, the function PxScene::getActiveActors() will always return a NULL list.
Default: False |
| eENABLE_CCD | Enables a second broad phase check after integration that makes it possible to prevent objects from tunneling through eachother. PxPairFlag::eDETECT_CCD_CONTACT requires this flag to be specified.
Default: False |
| eDISABLE_CCD_RESWEEP | Enables a simplified swept integration strategy, which sacrifices some accuracy for improved performance. This simplified swept integration approach makes certain assumptions about the motion of objects that are not made when using a full swept integration. These assumptions usually hold but there are cases where they could result in incorrect behavior between a set of fast-moving rigid bodies. A key issue is that fast-moving dynamic objects may tunnel through each-other after a rebound. This will not happen if this mode is disabled. However, this approach will be potentially faster than a full swept integration because it will perform significantly fewer sweeps in non-trivial scenes involving many fast-moving objects. This approach should successfully resist objects passing through the static environment. PxPairFlag::eDETECT_CCD_CONTACT requires this flag to be specified.
Default: False |
| eADAPTIVE_FORCE | Enable adaptive forces to accelerate convergence of the solver.
Default: false |
| eENABLE_PCM | Enable GJK-based distance collision detection system.
Default: true |
| eDISABLE_CONTACT_REPORT_BUFFER_RESIZE | Disable contact report buffer resize. Once the contact buffer is full, the rest of the contact reports will not be buffered and sent.
Default: false |
| eDISABLE_CONTACT_CACHE | Disable contact cache. Contact caches are used internally to provide faster contact generation. You can disable all contact caches if memory usage for this feature becomes too high.
Default: false |
| eREQUIRE_RW_LOCK | Require scene-level locking. When set to true this requires that threads accessing the PxScene use the multi-threaded lock methods.
Default: false |
| eENABLE_STABILIZATION | Enables additional stabilization pass in solver. When set to true, this enables additional stabilization processing to improve that stability of complex interactions between large numbers of bodies. Note that this flag is not mutable and must be set in PxSceneDesc at scene creation. Also, this is an experimental feature which does result in some loss of momentum. |
| eENABLE_AVERAGE_POINT | Enables average points in contact manifolds. When set to true, this enables additional contacts to be generated per manifold to represent the average point in a manifold. This can stabilize stacking when only a small number of solver iterations is used. Note that this flag is not mutable and must be set in PxSceneDesc at scene creation. |
| eEXCLUDE_KINEMATICS_FROM_ACTIVE_ACTORS | Do not report kinematics in list of active actors. Since the target pose for kinematics is set by the user, an application can track the activity state directly and use this flag to avoid that kinematics get added to the list of active actors.
Default: false |
| eENABLE_GPU_DYNAMICS | |
| eENABLE_ENHANCED_DETERMINISM | Provides improved determinism at the expense of performance. By default, PhysX provides limited determinism guarantees. Specifically, PhysX guarantees that the exact scene (same actors created in the same order) and simulated using the same time-stepping scheme should provide the exact same behaviour. However, if additional actors are added to the simulation, this can affect the behaviour of the existing actors in the simulation, even if the set of new actors do not interact with the existing actors. This flag provides an additional level of determinism that guarantees that the simulation will not change if additional actors are added to the simulation, provided those actors do not interfere with the existing actors in the scene. Determinism is only guaranteed if the actors are inserted in a consistent order each run in a newly-created scene and simulated using a consistent time-stepping scheme. Note that this flag is not mutable and must be set at scene creation. Note that enabling this flag can have a negative impact on performance. Note that this feature is not currently supported on GPU. Default false |
| eENABLE_FRICTION_EVERY_ITERATION | Controls processing friction in all solver iterations. By default, PhysX processes friction only in the final 3 position iterations, and all velocity iterations. This flag enables friction processing in all position and velocity iterations. The default behaviour provides a good trade-off between performance and stability and is aimed primarily at game development. When simulating more complex frictional behaviour, such as grasping of complex geometries with a robotic manipulator, better results can be achieved by enabling friction in all solver iterations.
