class PxFEMMaterial : public PxBaseMaterial

Material class to represent a set of FEM material properties.

Subclassed by PxFEMClothMaterial, PxFEMSoftBodyMaterial

Public Functions

virtual void setYoungsModulus(PxReal young) = 0

Sets young’s modulus which defines the body’s stiffness.

Parameters

young[in] Young’s modulus. Range: [0, PX_MAX_F32)

virtual PxReal getYoungsModulus() const = 0

Retrieves the young’s modulus value.

Returns

The young’s modulus value.

virtual void setPoissons(PxReal poisson) = 0

Sets the Poisson’s ratio which defines the body’s volume preservation.

Completely incompressible materials have a poisson ratio of 0.5. Its value should not be set to exactly 0.5 because this leads to numerical problems.

getPoissons()

Parameters

poisson[in] Poisson’s ratio. Range: [0, 0.5)

virtual PxReal getPoissons() const = 0

Retrieves the Poisson’s ratio.

See also

setPoissons()

Returns

The Poisson’s ratio.

virtual void setDynamicFriction(PxReal dynamicFriction) = 0

Sets the dynamic friction value which defines the strength of resistance when two objects slide relative to each other while in contact.

Parameters

dynamicFriction[in] The dynamic friction value. Range: [0, PX_MAX_F32)

virtual PxReal getDynamicFriction() const = 0

Retrieves the dynamic friction value.

Returns

The dynamic friction value

virtual void release() = 0

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

virtual PxU32 getReferenceCount() const = 0

Returns the reference count of the object.

At creation, the reference count of the object is 1. Every other object referencing this object increments the count by 1. When the reference count reaches 0, and only then, the object gets destroyed automatically.

Returns

the current reference count.

virtual void acquireReference() = 0

Acquires a counted reference to this object.

This method increases the reference count of the object by 1. Decrement the reference count by calling release()

virtual const char *getConcreteTypeName() const = 0

Returns string name of dynamic type.

Returns

Class name of most derived type of this object.

template<class T>
inline T *is()
template<class T>
inline const T *is() const
inline PxType getConcreteType() const

Returns concrete type of object.

See also

PxConcreteType

Returns

PxConcreteType::Enum of serialized object

inline void setBaseFlag(PxBaseFlag::Enum flag, bool value)

Set PxBaseFlag

Parameters
  • flag[in] The flag to be set

  • value[in] The flags new value

inline void setBaseFlags(PxBaseFlags inFlags)

Set PxBaseFlags

See also

PxBaseFlags

Parameters

inFlags[in] The flags to be set

inline PxBaseFlags getBaseFlags() const

Returns PxBaseFlags.

See also

PxBaseFlags

Returns

PxBaseFlags

inline virtual bool isReleasable() const

Whether the object is subordinate.

A class is subordinate, if it can only be instantiated in the context of another class.

Returns

Whether the class is subordinate
