Detailed Description

The U4DBVHCollision virtual class is in charge of testing collisions in the Broad-Phase stage.

Member Function Documentation

collision()

virtual void U4DEngine::U4DBVHCollision::collision ( U4DBVHNode< U4DDynamicAction > *  uTreeLeftNode, U4DBVHNode< U4DDynamicAction > *  uTreeRightNode, std::vector< U4DBroadPhaseCollisionModelPair > &  uBroadPhaseCollisionPairs  )

inlinevirtual

Method which detects collisions.

Parameters

uTreeLeftNode	Left tree node
uTreeRightNode	Right tree node
uBroadPhaseCollisionPairs	Container holding broad-phase collision pairs

Reimplemented in U4DEngine::U4DBVHModelCollision.

collisionBetweenTreeLeafNodes()

virtual void U4DEngine::U4DBVHCollision::collisionBetweenTreeLeafNodes ( U4DBVHNode< U4DDynamicAction > *  uTreeLeftNode, U4DBVHNode< U4DDynamicAction > *  uTreeRightNode, std::vector< U4DBroadPhaseCollisionModelPair > &  uBroadPhaseCollisionPairs  )

inlinevirtual

Method which detects broad-phase collision among tree nodes.

Parameters

uTreeLeftNode	Left tree node
uTreeRightNode	Right tree node
uBroadPhaseCollisionPairs	Container holding broad-phase collision pairs

Reimplemented in U4DEngine::U4DBVHModelCollision.

collisionBetweenTreeVolume()

bool U4DEngine::U4DBVHCollision::collisionBetweenTreeVolume	(	U4DBVHNode< U4DDynamicAction > *	uTreeLeftNode,
		U4DBVHNode< U4DDynamicAction > *	uTreeRightNode
	)

Method which tests collision among trees.

Parameters

uTreeLeftNode	Left tree node
uTreeRightNode	Right tree node

Returns

Returns true if the trees are colliding

descendTreeRule()

bool U4DEngine::U4DBVHCollision::descendTreeRule	(	U4DBVHNode< U4DDynamicAction > *	uTreeLeftNode,
		U4DBVHNode< U4DDynamicAction > *	uTreeRightNode
	)

Method used for the Tree descend rule.

Parameters

uTreeLeftNode	Left tree node
uTreeRightNode	Right tree node

Returns

Returns true if the left node first child is not a null pointer

startCollision()

virtual void U4DEngine::U4DBVHCollision::startCollision ( std::vector< std::shared_ptr< U4DBVHNode< U4DDynamicAction >>> &  uTreeContainer, std::vector< U4DBroadPhaseCollisionModelPair > &  uBroadPhaseCollisionPairs  )

inlinevirtual

Method which starts the broad-phase collision detection process.

Parameters

uTreeContainer	Tree container
uBroadPhaseCollisionPairs	Container holding broad-phase collision pairs

Reimplemented in U4DEngine::U4DBVHModelCollision.
