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();
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.GetNbBVPrimTests() = number of Triangle-BV overlap tests performed during last query
