Detailed Description

The btStridingMeshInterface is the interface class for high performance generic access to triangle meshes, used in combination with btBvhTriangleMeshShape and some other collision shapes. Using index striding of 3*sizeof(integer) it can use triangle arrays, using index striding of 1*sizeof(integer) it can handle triangle strips. It allows for sharing graphics and collision meshes. Also it provides locking/unlocking of graphics meshes that are in gpu memory.

int &  stride,
unsigned char **  indexbase,
int &  indexstride,
int &  numfaces,
PHY_ScalarType indicestype,
int  subpart = 0 
) [pure virtual]

get read and write access to a subpart of a triangle mesh this subpart has a continuous array of vertices and indices in this way the mesh can be handled as chunks of memory with striding very similar to OpenGL vertexarray support make a call to unLockVertexBase when the read and write access is finished

virtual int btStridingMeshInterface::getNumSubParts ( ) const [pure virtual]

getNumSubParts returns the number of seperate subparts each subpart has a continuous array of vertices and indices

virtual void btStridingMeshInterface::getPremadeAabb ( btVector3 *  aabbMin,
btVector3 *  aabbMax 
) const [inline, virtual]

virtual void btStridingMeshInterface::preallocateVertices ( int  numverts) [pure virtual]
virtual const char* btStridingMeshInterface::serialize ( void *  dataBuffer,
btSerializer serializer 
) const [virtual]

fills the dataBuffer and returns the struct name (and 0 on failure)

virtual void btStridingMeshInterface::setPremadeAabb ( const btVector3 &  aabbMin,
const btVector3 &  aabbMax 
) const [inline, virtual]

virtual void btStridingMeshInterface::unLockReadOnlyVertexBase ( int  subpart) const [pure virtual]
virtual void btStridingMeshInterface::unLockVertexBase ( int  subpart) [pure virtual]

unLockVertexBase finishes the access to a subpart of the triangle mesh make a call to unLockVertexBase when the read and write access (using getLockedVertexIndexBase) is finished
