-/**
- * 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:
- *
- * \code
- * Model Sample;
- *
- * OPCODECREATE OPCC;
- * OPCC.IMesh = ...;
- * OPCC.Rules = ...;
- * OPCC.NoLeaf = ...;
- * OPCC.Quantized = ...;
- * OPCC.KeepOriginal = ...;
- * bool Status = Sample.Build(OPCC);
- * \endcode
- *
- * 3) Create a tree collider and set it up:
- *
- * \code
- * AABBTreeCollider TC;
- * TC.SetFirstContact(...);
- * TC.SetFullBoxBoxTest(...);
- * TC.SetFullPrimBoxTest(...);
- * TC.SetTemporalCoherence(...);
- * \endcode
- *
- * 4) Perform a collision query
- *
- * \code
- * // 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()
- * \endcode
- *
- * 5) Stats
- *
- * \code
- * 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
- * \endcode
- *
- * \class Model
- * \author Pierre Terdiman
- * \version 1.3
