btOptimizedBvh::BT_DECLARE_ALIGNED_ALLOCATOR ( )

Reimplemented from btQuantizedBvh.

void btOptimizedBvh::build	(	btStridingMeshInterface *	triangles,
		bool	useQuantizedAabbCompression,
		const btVector3 &	bvhAabbMin,
		const btVector3 &	bvhAabbMax
	)

if the entire tree is small then subtree size, we need to create a header info for the tree

btOptimizedBvh * btOptimizedBvh::deSerializeInPlace	(	void *	i_alignedDataBuffer,
		unsigned int	i_dataBufferSize,
		bool	i_swapEndian
	)			`[static]`

deSerializeInPlace loads and initializes a BVH from a buffer in memory 'in place'

Reimplemented from btQuantizedBvh.

Definition at line 385 of file btOptimizedBvh.cpp.

now update all subtree headers

void btOptimizedBvh::refitPartial	(	btStridingMeshInterface *	triangles,
		const btVector3 &	aabbMin,
		const btVector3 &	aabbMax
	)

we should update all quantization values, using updateBvhNodes(meshInterface); but we only update chunks that overlap the given aabb

virtual bool btOptimizedBvh::serialize	(	void *	o_alignedDataBuffer,

Data buffer MUST be 16 byte aligned.
