/**
|
||||
* 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
