Detailed Description

A single potential-collision event involving a pair of primitives.

This class implements a cloth-cloth collider based on Bridson's 2002 paper (BriFedAnd02). We use it for several types of deformable collisions: cloth-cloth, cloth-hair and hair-hair. We also use it for thin plate rigid body collisions. This class can only be used for collision detection. The cloth subclass does the Bridson/Fedkiw/Anderson collision response.

For deformable objects, the input objects should be updated to the end-of-step positions and velocities. This collider will proposes changes to that end-of-step velocity which can then be used to obtain a new end-of-step position. The start-of-step position is calculated by assuming that explicit integration was used - i.e., by computing x - dt*v.

This class does both self-collision and object/object collision. It supports "point fusing," where two points in the same object (or one point in each of the two objects) are fused together into a single virtual point. (Typically, the user sets that up using a hard DOPs constraint.) For collision purposes, those points are treated as a single point - so, if two edges collide, but they share a virtual point as an endpoint, the collision will be ignored.

		int	leafId,
		int &	outPrimId,
		int &	outEdgeId
	)		const

protectedpure virtual

Given a leaf iterator and the id of a leaf, convert the leaf id to a primitive id and (optionally) an edge id.

Implemented in RBD_ColliderBFA.

virtual BV_LeafIterator* SIM_ColliderBFA::createLeafIt	(	const SIM_Object &	object,
		const SIM_Time &	timestep,
		bool	startPosOnly
	)		const

protectedpure virtual

This method should create a BV_LeafIterator class. This class will iterate over the individual geometric entities to be used for OBB intersection - in most cases, each leaf will contain a single primitive from the geometry. The time used to retrieve the geometry is determined by the startPosOnly flag: true: return the position at the start of the timestep - i.e., position at object - vel*timestep false: return the positions at both the start and end of the timestep. The leaf iterator should return points in simulation (world) space, not local object space.

Implemented in RBD_ColliderBFA.

virtual bool SIM_ColliderBFA::doCheckTangle ( ) const

inlineprotectedvirtual

returns true iff tangling triangles should not be processed for collision detection The RBD collision detection uses this to allow objects that are tangled at the start of the timestep to untangle without the attempt to disentangle triggering a collision.

Reimplemented in RBD_ColliderBFA.

Collision detection for rigid bodies. These bodies: 1) define velocity via start/end transforms 2) never need to update their bounding volume trees. 3) need proxy triangulated geometry, since the source geometry may not be triangles.

Test if this class generates events located at the centre of the triangles/edges or at the surface. This choice usually depends on the model of collision response.

int SIM_ColliderBFA::getFusePointId ( int pid ) const

inline

Retrieve the "simulation" point id (or "equation number") associated with the given point. This allows for testing if points from two different gdps are "fused" into a single point within the simulation. It is stored as an attribute on the GU_Detail. Collisions between fused points are ignored. If the attribute is absent, fusing is disabled.
