Detailed Description

cCollisionAABBLeaf contains methods to set up leaf nodes of an AABB tree and to use them to detect for collision with a line.

bool cCollisionAABBLeaf::computeCollision	(	cVector3d &	a_segmentPointA,
		cVector3d &	a_segmentPointB,
		cCollisionAABBBox &	a_lineBox,
		cCollisionRecorder &	a_recorder,
		cCollisionSettings &	a_settings
	)			`[virtual]`

Determine whether the given line intersects this leaf's triangle.

Determine whether the given line intersects the triangle belonging to this leaf node by calling the triangle's collision detection method.

Parameters:

	a_segmentPointA	Initial point of segment.
	a_segmentPointB	End point of segment.
	a_lineBox	A bounding box for the incoming segment, for quick discarding of collision tests.
	a_recorder	Stores all collision events.
	a_settings	Contains collision settings information.

Returns:: Return true if the line segment intersects the leaf's triangle.

void cCollisionAABBLeaf::fitBBox ( double a_radius = 0 ) [virtual]

Create a bounding box to enclose triangle belonging to this leaf node.

Create a bounding box to enclose the three vertices of the triangle belonging to the leaf node.

Parameters:

a_radius

Radius around the triangle

Reimplemented from cCollisionAABBNode.

void cCollisionAABBLeaf::render ( int a_depth = -1 ) [virtual]

Draw the edges of the bounding box for this leaf if it is at depth a_depth.

Render bounding box of leaf node if it is at level a_depth in the tree.

Parameters:

a_depth

Only draw nodes at this depth in the tree. a_depth < 0 render _up to_ abs(a_depth).
