Detailed Description

The main collision wrapper, for all trees. Supported trees are:

Normal trees (2*N-1 nodes, full size)
No-leaf trees (N-1 nodes, full size)
Quantized trees (2*N-1 nodes, half size)
Quantized no-leaf trees (N-1 nodes, half size)

Usage:

1) Create a static mesh interface using callbacks or pointers. (see OPC_MeshInterface.cpp). Keep it around in your app, since a pointer to this interface is saved internally and used until you release the collision structures.

2) Build a Model using a creation structure:

Model Sample;
 
OPCODECREATE OPCC;
OPCC.IMesh                      = ...;
OPCC.Rules                      = ...;
OPCC.NoLeaf                     = ...;
OPCC.Quantized          = ...;
OPCC.KeepOriginal       = ...;
bool Status = Sample.Build(OPCC);

3) Create a tree collider and set it up:

AABBTreeCollider TC;
TC.SetFirstContact(...);
TC.SetFullBoxBoxTest(...);
TC.SetFullPrimBoxTest(...);
TC.SetTemporalCoherence(...);

4) Perform a collision query

// Setup cache
static BVTCache ColCache;
ColCache.Model0 = &Model0;
ColCache.Model1 = &Model1;
 
// Collision query
bool IsOk = TC.Collide(ColCache, World0, World1);
 
// Get collision status => if true, objects overlap
BOOL Status = TC.GetContactStatus();
 
// Number of colliding pairs and list of pairs
udword NbPairs = TC.GetNbPairs();
const Pair* p = TC.GetPairs()

5) Stats

Model0.GetUsedBytes()   = number of bytes used for this collision tree
TC.GetNbBVBVTests()             = number of BV-BV overlap tests performed during last query
TC.GetNbPrimPrimTests() = number of Triangle-Triangle overlap tests performed during last query
TC.GetNbBVPrimTests()   = number of Triangle-BV overlap tests performed during last query
