static inline PxShape *createExclusiveShape(PxRigidActor &actor, const PxGeometry &geometry, PxMaterial *const *materials, PxU16 materialCount, PxShapeFlags shapeFlags = PxShapeFlag::eVISUALIZATION | PxShapeFlag::eSCENE_QUERY_SHAPE | PxShapeFlag::eSIMULATION_SHAPE)
Creates a new shape with default properties and a list of materials and adds it to the list of shapes of this actor.
This is equivalent to the following
PxShape* shape(…) = PxGetPhysics().createShape(…); // reference count is 1 actor->attachShape(shape); // increments reference count shape->release(); // releases user reference, leaving reference count at 1
As a consequence, detachShape() will result in the release of the last reference, and the shape will be deleted.
Sleeping: Does NOT wake the actor up automatically.
Note
The default shape flags to be set are: eVISUALIZATION, eSIMULATION_SHAPE, eSCENE_QUERY_SHAPE (see PxShapeFlag). Triangle mesh, heightfield or plane geometry shapes configured as eSIMULATION_SHAPE are not supported for non-kinematic PxRigidDynamic instances.
Note
Creating compounds with a very large number of shapes may adversely affect performance and stability.
- Parameters
actor – [in] the actor to which to attach the shape
geometry – [in] the geometry of the shape
materials – [in] a pointer to an array of material pointers
materialCount – [in] the count of materials
shapeFlags – [in] optional PxShapeFlags
- Returns
The newly created shape.

static inline PxShape *createExclusiveShape(PxRigidActor &actor, const PxGeometry &geometry, const PxMaterial &material, PxShapeFlags shapeFlags = PxShapeFlag::eVISUALIZATION | PxShapeFlag::eSCENE_QUERY_SHAPE | PxShapeFlag::eSIMULATION_SHAPE)
Creates a new shape with default properties and a single material adds it to the list of shapes of this actor.
This is equivalent to the following
PxShape* shape(…) = PxGetPhysics().createShape(…); // reference count is 1 actor->attachShape(shape); // increments reference count shape->release(); // releases user reference, leaving reference count at 1
As a consequence, detachShape() will result in the release of the last reference, and the shape will be deleted.
Sleeping: Does NOT wake the actor up automatically.
Note
The default shape flags to be set are: eVISUALIZATION, eSIMULATION_SHAPE, eSCENE_QUERY_SHAPE (see PxShapeFlag). Triangle mesh, heightfield or plane geometry shapes configured as eSIMULATION_SHAPE are not supported for non-kinematic PxRigidDynamic instances.
Note
Creating compounds with a very large number of shapes may adversely affect performance and stability.
- Parameters
actor – [in] the actor to which to attach the shape
geometry – [in] the geometry of the shape
material – [in] the material for the shape
shapeFlags – [in] optional PxShapeFlags
- Returns
The newly created shape.
-
static PxBounds3 *getRigidActorShapeLocalBoundsList(const PxRigidActor &actor, PxU32 &numBounds)
Gets a list of bounds based on shapes in rigid actor.
This list can be used to cook/create bounding volume hierarchy though PxCooking API.
- Parameters
actor – [in] The actor from which the bounds list is retrieved.
numBounds – [out] Number of bounds in returned list.
-
static PxBVH *createBVHFromActor(PxPhysics &physics, const PxRigidActor &actor)
Convenience function to create a PxBVH object from a PxRigidActor.
The computed PxBVH can then be used in PxScene::addActor() or PxAggregate::addActor(). After adding the actor & BVH to the scene/aggregate, release the PxBVH object by calling PxBVH::release().
