blaze.collision.nbody.broadPhase

struct SPHContact ;

Shape contact

Shape shape1 ;

The first shape

Shape shape2 ;

The second shape

class BroadPhase ;

Broad-phase collison detection

Contact[int] contactPool ;

Contact pair list

Shape[] shapes ;

World shape list

SPHContact [] sphList ;

Particle/shape contact list

this(World world);

Constructor

Params:

World world

the world that the collision detection will be done for

protected void resetContactPool ();

Reset the contact pool.

protected void updatePool (int i1, int i2);

Add new contacts to the contact pool, and update existing contacts

Params:

int i1	index of the first shape
int i2	index of the second shape

protected void scrubContactPool ();

Remove contacts who's bounding boxes are no longer overlaping. All keys left in the arbiter pool are no longer valid.

void addShape (Shape s);

Add shape to the shape list

Parmas:
s = the shape to add

void removeShape (Shape s);

Remove shape from the shape list

Params:

Shape s

the shape to remove

void removeBodyContacts (Body b);

Removes all contacts for a given body

Params:

Body b

the body whose contacts sholud be removed

void query (AABB aabb, ref Shape[] results);

Brute force query for overlapping AABB

Params:

AABB aabb	The box that shapes are being tested for
Shape[] results	The shapes that intersect the box

BUGS:
does not perform contact filtering

void processFluidContacts ();

Process the fluid/shape contacts

abstract void search ();

Update broadphase

uint hash (uint ID1, uint ID2);

Thomas Wang's hash . This assumes Id1 and Id2 are 16-bit.
