Static Protected Member Functions inherited from Vx::VxBase  
static void  resetVxBaseCounter () 
Defines a volume and shape in space that the Dynamics can use to compute collision for a rigid body.
The shape and volume are defined by creating a primitive geometry using one of the Vx::VxGeometry subclasses.
It also holds the specific collision response properties associated with the shape.
It provides utility functions that enable the user to:
Geometries can be shared between collision geometries and are referencecounted.
Allows the user to tune different levels of the disabled status for collision geometries.
Vx::VxCollisionGeometry::VxCollisionGeometry  (  VxGeometry *  geometry, 
VxMaterial *  material  
) 
Constructor with geometry and material.

Vx::VxCollisionGeometry::VxCollisionGeometry  (  VxGeometry *  geometry, 
VxMaterial *  material,  
const VxTransform &  transform  
) 
Constructor with geometry, material and transform.
The geometry is referencecounted. Does not take ownership of the material.

virtual 
Destructor.
Also destroys the contained geometry if it's not referenced by another collision geometry; otherwise decrements its reference count.
void Vx::VxCollisionGeometry::addFilterBox  (  const VxOBB &  filterBox  ) 
Adds a filter box to this collision geometry.
Inside this box, contacts with other collision geometries or intersections with line segments will not be created.
bool Vx::VxCollisionGeometry::assignResponseID  (  ResponseType  id  ) 
Assigns the given response ID to this collision geometry.
The response IDs in a collision geometry define the actions (or responses) which should occur once the collision geometry collides with another collision geometry. The actions (or responses) which are performed are defined by response models . Each response model which is registered in a universe has a unique, associated response ID , which can be associated to collision geometries using this function. When two collision geometries intersect, every pair of response IDs of the respective collision geometries, will lead to a different response. After construction a collision geometry has the response ID VxUniverse::kResponseRigidBody assigned, and will thus cause compliant contact response when colliding with a collision geometry which also has the ID VxUniverse::kResponseRigidBody.

virtual 
Creates and returns a new VxCollisionGeometry.
If you specify true, the geometry is also cloned; otherwise it is shared.

Reimplemented in Vx::VxCompositeCollisionGeometry.
void Vx::VxCollisionGeometry::enableCollision  (  bool  value  ) 
True to enable collision; false to remove this geometry from the collision detection.
This VxCollisionGeometry may be not removed from its part as it can be still in used for the mass property or for fluid interaction.

virtual 
Sets the fast moving flag.
By default, intersections between collision geometries are only computed at the beginning of the step, using the current position of collision geometries. Then, the dynamics is computed and the collision geometries are moved. This makes it possible for objects to pass through each other undetected if they are going fast enough. This is a typical discretization issue.
A fastmoving collision geometry will force Vortex to take the collision geometry's part velocity into account for the purpose of collision detection. This is achieved by considering an extruded volume from the position at the beginning of the step, and the projected position at the end of the step, based on the velocity.
Setting this flag will eliminate some discretization issues of fastmoving objects, hence the name.
However, the drawback is that the point of impact will still be set as if it occurred at the beginning the step. For more precision, see continuous collision detection.

void Vx::VxCollisionGeometry::enableFluidInteraction  (  bool  value  )

bool Vx::VxCollisionGeometry::replaceAllResponseIDs  (  ResponseType  newID  )

) by the new response ID (newID

void Vx::VxCollisionGeometry::setContactTolerance  (  double  value  )

param[in] buoyancyCenter Currently only used if the geometry is completely submerged. param[in] drag Drag coefficient must be positive param[in] buoyancyForceScale Accounts for the difference of volume between the collision geometry and the real object. param[in] magnus Magnus coefficient must be positive (defaults to 0). Currently implemented for the sphere and the cylinder geometry only.
Reimplemented in Vx::VxCompositeCollisionGeometry.
void Vx::VxCollisionGeometry::setFluidInteractionForceFn  (  VxFluidInteractionForceFn  fn  ) 
Sets the fluid interaction force function.
The interaction of all fluids added to the universe is computed using this function.

virtual 
Sets the geometry for this collision geometry.
Reimplemented in Vx::VxCompositeCollisionGeometry.
void Vx::VxCollisionGeometry::setIntersectFilter  (  VxIntersectFilter *  f  ) 
Sets an intersect filter for this collision geometry.
An intersect filter allows interactive collision geometry pair disabling. It is especially useful for disabling pairs with collision geometries added to composite collision geometries, as the child collision geometries are not supported by VxUniverse::disablePairsWith calls or collision rules .

virtual 
Sets the material associated to the geometry.
[in]  iMaterial  Must be either a valid VxMaterial , created by the VxMaterialTable or NULL (for the default material). 
Reimplemented in Vx::VxCompositeCollisionGeometry.
bool Vx::VxCollisionGeometry::setRequestID  (  int  id, 
bool  updateExistingPairs = true 

) 
Sets the requestID of the collision geometry.
This ID is typically used to define sets of collision geometries. Each set is specified by a different request ID set by the user, starting at 0.
Each pair of request IDs corresponds to a VxCollisionPairRequest in which different parameters used by the collision detection are stored. Use this method to set request IDs for those collision geometries.
The default request ID depends on the type of geometry inside this collision geometry. See VxGeometry::getDefaultRequestID for more information.
updateExistingPairs
== true (default), the change takes immediate effect on existing overlaps with the AABB of this collision geometry in the collision detection. Otherwise, the change will take effect only on new overlaps.

virtual 
Sets the static flag.
A static collision geometry cannot move. This is an assumption used by the broad phase of collision detection, yielding some performance gains.
The transform of a static collision geometry cannot be changed while it remains static. It will not be recomputed automatically like other collision geometries, even if you move it or call the updateAbsoluteTransform method. The only way change it's transform is to remove the static flag.
If this collision geometry is not in any universe, calling this method has no effect.
Reimplemented in Vx::VxCompositeCollisionGeometry.
void Vx::VxCollisionGeometry::setTemporaryDisabledStatus  (  TemporaryDisabledStatus  status  ) 
Sets the temporary disabled status.
When a geometry is temporarily disabled, the disabled pairs involving this geometry are still maintained. The VxCollisionGeometry::kTemporaryDisabledShortTerm option can be applied at no cost.
No collision involving this geometry is computed but the geometry position is still maintained so there is still a runtime cost for this geometry. The VxCollisionGeometry::kTemporaryDisabledLongTerm option is similar to calling setCollisionEnabled(false) except that the disabled pairs are still maintained. There is a cost to use this option but once set to kTemporaryDisabledLongTerm
, there is no more runtime cost for this geometry.
void Vx::VxCollisionGeometry::setTransformAbsolute  (  const VxTransform &  absoluteTransform  ) 
Sets the absolute transform .
Sets the transform by computing the offset necessary to obtain the specified absolute transform from the transform of the object containing the collision geometry.
If there is no object containing the collision geometry, this sets the absolute transform directly, without any computation.
Note that this method will have no effect if the static flag is set.
void Vx::VxCollisionGeometry::setTransformRelative  (  const VxTransform &  transform  ) 
Sets the relative transform .
Note that this method will have no effect if the static flag is set.

virtual 
Updates the collision geometry's absolute transform.
The collision geometry's absolute transform is computed at the beginning of each step. Therefore after the integration (at the end of the step) the absolute transform of the collision geometry is one step late.
Note that this method will have no effect if the static flag is set.
Note: This could be required if the collision geometry is disabled (see setCollisionEnabled) and an uptodate transform is needed. If a collision geometry is disabled, it is not used in the collision detection. So we do not update the absolute transform automatically in this case as a performance optimization.
Reimplemented in Vx::VxCompositeCollisionGeometry.
