Detailed Description

A class for describing a shape's surface properties.

You can create a material which has different friction coefficients depending on the direction that a body in contact is trying to move in. This is called anisotropic friction.

Anisotropic friction is useful for modeling things like sledges, skis etc

When you create an anisotropic material you specify the default friction parameters and also friction parameters for the V axis. The friction parameters for the V axis are applied to motion along the direction of anisotropy (dirOfAnisotropy).

Default material: You can change the properties of the default material by querying for material index 0.

void PhysxMaterial::load_from_desc ( const PhysxMaterialDesc materialDesc)

Loads the entire state of the material from a descriptor with a single call.

Definition at line 108 of file physxMaterial.cxx.

void ReferenceCount::local_object ( ) [inline, inherited]

This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.

This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

void ReferenceCount::ref ( ) const [inline, inherited]

Explicitly increments the reference count.

User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.

This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

void PhysxMaterial::save_to_desc ( PhysxMaterialDesc materialDesc) const

Saves the state of the material object to a descriptor.

void PhysxMaterial::set_dir_of_anisotropy ( const LVector3f  dir)

Sets the shape space direction (unit vector) of anisotropy.

This is only used if the flag MF_anisotropic is set.

Definition at line 311 of file physxMaterial.cxx.

References PhysxManager::vec3_to_nxVec3().

void PhysxMaterial::set_dynamic_friction ( float  coef)

Sets the coefficient of dynamic friction.

The coefficient of dynamic friction should be in [0, +inf]. If set to greater than staticFriction, the effective value of staticFriction will be increased to match. If the flag MF_anisotropic is set, then this value is used for the primary direction of anisotropy (U axis).

Definition at line 196 of file physxMaterial.cxx.

void PhysxMaterial::set_dynamic_friction_v ( float  coef)

Sets the dynamic friction coefficient along the secondary (V) axis.

This is used when anisotropic friction is being applied. I.e. the flag MF_anisotropic is set.

Definition at line 251 of file physxMaterial.cxx.

void PhysxMaterial::set_flag ( PhysxMaterialFlag  flag,
bool  value 
)

Sets the value of a single flag.

Definition at line 276 of file physxMaterial.cxx.

void PhysxMaterial::set_friction_combine_mode ( PhysxCombineMode  mode)

Sets the friction combine mode.

  • CM_average : Average: (a + b)/2.
  • CM_min : Minimum: min(a,b).
  • CM_multiply : Multiply: a*b.
  • CM_max : Maximum: max(a,b).

Definition at line 339 of file physxMaterial.cxx.

void PhysxMaterial::set_restitution ( float  restitution)

Sets the coefficient of restitution.

A coefficient of 0 makes the object bounce as little as possible, higher values up to 1.0 result in more bounce.

Definition at line 136 of file physxMaterial.cxx.

void PhysxMaterial::set_restitution_combine_mode ( PhysxCombineMode  mode)

Sets the restitution combine mode.

  • CM_average : Average: (a + b)/2.
  • CM_min : Minimum: min(a,b).
  • CM_multiply : Multiply: a*b.
  • CM_max : Maximum: max(a,b).

Definition at line 367 of file physxMaterial.cxx.

void PhysxMaterial::set_static_friction ( float  coef)

Sets the coefficient of static friction.

The coefficient of static friction should be in the range [0, +inf]. If the flag MF_anisotropic is set, then this value is used for the primary direction of anisotropy (U axis).

Definition at line 165 of file physxMaterial.cxx.

void PhysxMaterial::set_static_friction_v ( float  coef)

Sets the static friction coefficient along the secondary (V) axis.

This is used when anisotropic friction is being applied. I.e. the flag MF_anisotropic is set.

bool ReferenceCount::test_ref_count_integrity ( ) const [inline, inherited]
bool ReferenceCount::test_ref_count_nonzero ( ) const [inline, inherited]

Does some easy checks to make sure that the reference count isn't zero, or completely bogus.

Returns true if ok, false otherwise.

References ReferenceCount::do_test_ref_count_nonzero().

Referenced by CopyOnWritePointer::test_ref_count_nonzero().

bool ReferenceCount::unref ( ) const [inline, virtual, inherited]

Explicitly decrements the reference count.

Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete().

User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.

This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

The return value is true if the new reference count is nonzero, false if it is zero.

It must have previously been added via a call to weak_ref().
