Member Function Documentation

◆ computeData() [1/2]

void CollisionVolumeOBB::computeData	(	const Vect &	minWorldVertex,
		const Vect &	maxWorldVertex,
		const Matrix &	worldMatrix
	)

Calculates the data for OBB. In this case the center.

Parameters

minWorldVertex	The min local vertex.
maxWorldVertex	The max local vertex.
worldMatrix	The world matrix.

◆ computeData() [2/2]

void CollisionVolumeOBB::computeData	(	Model *	pModel,
		const Matrix &	worldMatrix
	)

overridevirtual

Calculates the data for OBB. In this case the center.

Parameters

pModel	the pointer to a model.
worldMatrix	The world matrix.

Implements CollisionVolume.

◆ debugDraw()

void CollisionVolumeOBB::debugDraw	(	const Vect &	color,
		int	depth
	)		const

overrideprivatevirtual

Draws it collision volume.

Used for debuggin purposes. Depth value is used only for Octree collision value. All other collision volumes ignore it.

Parameters

color	the color to render the collision volume.
depth	the depth to render collision volume.

Implements CollisionVolume.

◆ getInverseWorldMatrix()

const Matrix & CollisionVolumeOBB::getInverseWorldMatrix ( ) const

Gets the inverse world matrix of OBB.

Returns: The world matrix.

◆ getLocalHalfDiagonal()

const Vect & CollisionVolumeOBB::getLocalHalfDiagonal ( ) const

Gets the half diagonal of OBB in local space.

Returns: The half diagonal.

◆ getMaxLocalVertex()

const Vect & CollisionVolumeOBB::getMaxLocalVertex ( ) const

Gets the maximum vertex in local space.

Returns: The maximum vertex.

◆ getMinLocalVertex()

const Vect & CollisionVolumeOBB::getMinLocalVertex ( ) const

Gets the minimum vertex in local space.

Returns: The minimum vertex.

◆ getScalingFactorSquared()

float CollisionVolumeOBB::getScalingFactorSquared ( ) const

Gets scaling factor sqaured of OBB.

Returns: The scaling factor squared.

◆ getWorldCenter()

const Vect & CollisionVolumeOBB::getWorldCenter ( ) const

Gets the center position of OBB in world space.

Returns: The center.

◆ getWorldMatrix()

const Matrix & CollisionVolumeOBB::getWorldMatrix ( ) const

Gets the world matrix of OBB.

Returns: The world matrix.

◆ intersectAccept()

bool CollisionVolumeOBB::intersectAccept ( const CollisionVolume & collisionVolume ) const

Implements CollisionVolume.

◆ intersectVisitor() [1/4]

bool CollisionVolumeOBB::intersectVisitor ( const CollisionVolumeAABB & AABB ) const

overridevirtual

Visits a collision volume AABB to perform intersect test.

Uses Visitor Pattern. This is the second step of the process.

Parameters

AABB	a collision volume AABB.

Implements CollisionVolume.

◆ intersectVisitor() [2/4]

bool CollisionVolumeOBB::intersectVisitor ( const CollisionVolumeBSphere & collisionBSphere ) const

overridevirtual

Visits a collision volume BSphere to perform intersect test.

Uses Visitor Pattern. This is the second step of the process.

Parameters

collisionBSphere a collision volume BSphere.

Implements CollisionVolume.

◆ intersectVisitor() [3/4]

bool CollisionVolumeOBB::intersectVisitor ( const CollisionVolumeOBB & OBB ) const

overridevirtual

Visits a collision volume OBB to perform intersect test.

Uses Visitor Pattern. This is the second step of the process.

Parameters

OBB	a collision volume OBB.

Implements CollisionVolume.

◆ intersectVisitor() [4/4]

bool CollisionVolumeOBB::intersectVisitor ( const CollisionVolumeOctree & Octree ) const

overridevirtual

Visits a collision volume Octree to perform intersect test.

Uses Visitor Pattern. This is the second step of the process.

Parameters

Octree a collision volume Octree.

Implements CollisionVolume.

◆ setMinMaxLocalVertex()

void CollisionVolumeOBB::setMinMaxLocalVertex	(	const Vect &	minlocalVertex,
		const Vect &	maxlocalVertex
	)

Sets the minimum and maximum vertex in local space.

Parameters

minWorldVertex	The min local vertex.
maxWorldVertex	The max local vertex.

◆ setWorldMatrix()

void CollisionVolumeOBB::setWorldMatrix ( const Matrix & worldMatrix )

Sets the world matrix.

Parameters

worldMatrix The world matrix.
