References PxBase::isKindOf().

virtual void PxShape::release (  )  [pure virtual]

Decrements the reference count of a shape and releases it if the new reference count is zero.

Note that in releases prior to PhysX 3.3 this method did not have reference counting semantics and was used to destroy a shape created with PxActor::createShape(). In PhysX 3.3 and above, this usage is deprecated, instead, use PxRigidActor::detachShape() to detach a shape from an actor. If the shape to be detached was created with PxActor::createShape(), the actor holds the only counted reference, and so when the shape is detached it will also be destroyed.

See also:
PxRigidActor::createShape() PxPhysics::createShape() PxRigidActor::attachShape() PxRigidActor::detachShape()

Implements PxBase.

Referenced by PxRigidActorExt::createExclusiveShape().

virtual void PxShape::setContactOffset ( PxReal  contactOffset  )  [pure virtual]

Sets the contact offset.

Shapes whose distance is less than the sum of their contactOffset values will generate contacts. The contact offset must be positive and greater than the rest offset. Having a contactOffset greater than than the restOffset allows the collision detection system to predictively enforce the contact constraint even when the objects are slightly separated. This prevents jitter that would occur if the constraint were enforced only when shapes were within the rest distance.

Default: 0.02f * PxTolerancesScale::length

Sleeping: Does NOT wake the associated actor up automatically.

Parameters:
[in] contactOffset Range: [maximum(0,restOffset), PX_MAX_F32)
See also:
getContactOffset PxTolerancesScale setRestOffset

virtual void PxShape::setFlag ( PxShapeFlag::Enum  flag,
bool  value 
) [pure virtual]

Sets shape flags.

Sleeping: Does NOT wake the associated actor up automatically.

Parameters:
[in] flag The shape flag to enable/disable. See PxShapeFlag.
[in] value True to set the flag. False to clear the flag specified in flag.
Default: PxShapeFlag::eVISUALIZATION | PxShapeFlag::eSIMULATION_SHAPE | PxShapeFlag::eSCENE_QUERY_SHAPE

See also:
PxShapeFlag getFlags()

virtual void PxShape::setFlags ( PxShapeFlags  inFlags  )  [pure virtual]

Sets shape flags.

See also:
PxShapeFlag getFlags()

virtual void PxShape::setGeometry ( const PxGeometry geometry  )  [pure virtual]

Adjust the geometry of the shape.

Note:
The type of the passed in geometry must match the geometry type of the shape.

It is not allowed to change the geometry type of a shape.

This function does not guarantee correct/continuous behavior when objects are resting on top of old or new geometry.

Parameters:
[in] geometry New geometry of the shape.
See also:
PxGeometry PxGeometryType getGeometryType()

virtual void PxShape::setLocalPose ( const PxTransform pose  )  [pure virtual]

Sets the pose of the shape in actor space, i.e. relative to the actors to which they are attached.

This transformation is identity by default.

The local pose is an attribute of the shape, and so will apply to all actors to which the shape is attached.

Sleeping: Does NOT wake the associated actor up automatically.

Note: Does not automatically update the inertia properties of the owning actor (if applicable); use the PhysX extensions method PxRigidBodyExt::updateMassAndInertia() to do this.

Default: the identity transform

Parameters:
[in] pose The new transform from the actor frame to the shape frame. Range: rigid body transform
See also:
getLocalPose()

virtual void PxShape::setMaterials ( PxMaterial *const *  materials,
PxU16  materialCount 
) [pure virtual]

Assigns material(s) to the shape.

Sleeping: Does NOT wake the associated actor up automatically.

Parameters:
[in] materials List of material pointers to assign to the shape. See PxMaterial
[in] materialCount The number of materials provided.
See also:
PxPhysics.createMaterial() getMaterials()

virtual void PxShape::setName ( const char *  name  )  [pure virtual]

Sets a name string for the object that can be retrieved with getName().

This is for debugging and is not used by the SDK. The string is not copied by the SDK, only the pointer is stored.

Default: NULL

Parameters:
[in] name The name string to set the objects name to.
See also:
getName()

virtual void PxShape::setQueryFilterData ( const PxFilterData data  )  [pure virtual]

Sets the user definable query filter data.

Default: (0,0,0,0)

See also:
getQueryFilterData()

virtual void PxShape::setRestOffset ( PxReal  restOffset  )  [pure virtual]

Sets the rest offset.

Two shapes will come to rest at a distance equal to the sum of their restOffset values. If the restOffset is 0, they should converge to touching exactly. Having a restOffset greater than zero is useful to have objects slide smoothly, so that they do not get hung up on irregularities of each others' surfaces.

Default: 0.0f

Sleeping: Does NOT wake the associated actor up automatically.

Parameters:
[in] restOffset Range: (-PX_MAX_F32, contactOffset)
See also:
getRestOffset setContactOffset

virtual void PxShape::setSimulationFilterData ( const PxFilterData data  )  [pure virtual]

Sets the user definable collision filter data.

Sleeping: Does wake up the actor if the filter data change causes a formerly suppressed collision pair to be enabled.

Default: (0,0,0,0)

See also:
getSimulationFilterData()
