Function Documentation

MR_AABBTree_AssignFromAnother()

MRC_API MR_AABBTree * MR_AABBTree_AssignFromAnother	(	MR_AABBTree *	_this,
		MR_PassBy	_other_pass_by,
		MR_AABBTree *	_other )

Generated from a method of class MR::AABBTree named operator=. Parameter _this can not be null. It is a single object. The returned pointer will never be null. It is non-owning, do NOT destroy it.

MR_AABBTree_Construct()

MRC_API MR_AABBTree * MR_AABBTree_Construct

(

const MR_MeshPart *

mp

)

creates tree for given mesh or its part Generated from a constructor of class MR::AABBTree. Parameter mp can not be null. It is a single object. Never returns null. Returns an instance allocated on the heap! Must call MR_AABBTree_Destroy() to free it when you're done using it.

MR_AABBTree_ConstructFromAnother()

MRC_API MR_AABBTree * MR_AABBTree_ConstructFromAnother	(	MR_PassBy	_other_pass_by,
		MR_AABBTree *	_other )

Generated from a constructor of class MR::AABBTree. Never returns null. Returns an instance allocated on the heap! Must call MR_AABBTree_Destroy() to free it when you're done using it.

MR_AABBTree_DefaultConstruct()

MRC_API MR_AABBTree * MR_AABBTree_DefaultConstruct

(

void

)

Constructs an empty (default-constructed) instance. Never returns null. Returns an instance allocated on the heap! Must call MR_AABBTree_Destroy() to free it when you're done using it.

MR_AABBTree_DefaultConstructArray()

MRC_API MR_AABBTree * MR_AABBTree_DefaultConstructArray

(

size_t

num_elems

)

Constructs an array of empty (default-constructed) instances, of the specified size. Will never return null. The array must be destroyed using MR_AABBTree_DestroyArray(). Use MR_AABBTree_OffsetMutablePtr() and MR_AABBTree_OffsetPtr() to access the array elements.

MR_AABBTree_Destroy()

MRC_API void MR_AABBTree_Destroy

(

const MR_AABBTree *

_this

)

Destroys a heap-allocated instance of MR_AABBTree. Does nothing if the pointer is null.

MR_AABBTree_DestroyArray()

MRC_API void MR_AABBTree_DestroyArray

(

const MR_AABBTree *

_this

)

Destroys a heap-allocated array of MR_AABBTree. Does nothing if the pointer is null.

MR_AABBTree_MutableUpcastTo_MR_AABBTreeBase_MR_AABBTreeTraits_MR_FaceTag_MR_Box3f()

MRC_API MR_AABBTreeBase_MR_AABBTreeTraits_MR_FaceTag_MR_Box3f * MR_AABBTree_MutableUpcastTo_MR_AABBTreeBase_MR_AABBTreeTraits_MR_FaceTag_MR_Box3f

(

MR_AABBTree *

object

)

Upcasts an instance of MR::AABBTree to its base class MR::AABBTreeBase<MR::AABBTreeTraits<MR::FaceTag, MR::Box3f>>.

MR_AABBTree_OffsetMutablePtr()

MRC_API MR_AABBTree * MR_AABBTree_OffsetMutablePtr	(	MR_AABBTree *	ptr,
		ptrdiff_t	i )

Offsets a pointer to an array element by i positions (not bytes). Use only if you're certain that the pointer points to an array element.

MR_AABBTree_OffsetPtr()

MRC_API const MR_AABBTree * MR_AABBTree_OffsetPtr	(	const MR_AABBTree *	ptr,
		ptrdiff_t	i )

Offsets a pointer to an array element by i positions (not bytes). Use only if you're certain that the pointer points to an array element.

MR_AABBTree_refit()

MRC_API void MR_AABBTree_refit	(	MR_AABBTree *	_this,
		const MR_Mesh *	mesh,
		const MR_VertBitSet *	changedVerts )

updates bounding boxes of the nodes containing changed vertices; this is a faster alternative to full tree rebuild (but the tree after refit might be less efficient)

Parameters

mesh	same mesh for which this tree was constructed but with updated coordinates;
changedVerts	vertex ids with modified coordinates (since tree construction or last refit) Generated from a method of class MR::AABBTree named refit. Parameter _this can not be null. It is a single object. Parameter mesh can not be null. It is a single object. Parameter changedVerts can not be null. It is a single object.

MR_AABBTree_UpcastTo_MR_AABBTreeBase_MR_AABBTreeTraits_MR_FaceTag_MR_Box3f()

MRC_API const MR_AABBTreeBase_MR_AABBTreeTraits_MR_FaceTag_MR_Box3f * MR_AABBTree_UpcastTo_MR_AABBTreeBase_MR_AABBTreeTraits_MR_FaceTag_MR_Box3f

(

const MR_AABBTree *

object

)

Upcasts an instance of MR::AABBTree to its base class MR::AABBTreeBase<MR::AABBTreeTraits<MR::FaceTag, MR::Box3f>>. This version is acting on mutable pointers.
