resFunc	callback that gets a block of resulting winding numbers
dims	dimensions of the grid
gridToMeshXf	transform from integer grid locations to voxel's centers in mesh reference frame
beta	determines the precision of the approximation: the more the better, recommended value 2 or more
layerOverlap	overlap between two blocks of the grid, set as XY layer count

Generated from a method of class MR::IFastWindingNumberByParts named calcFromGridByParts. Parameter _this can not be null. It is a single object. Parameter dims can not be null. It is a single object. Parameter gridToMeshXf can not be null. It is a single object. Parameter cb can not be null. It is a single object. Never returns null. Returns an instance allocated on the heap! Must call MR_expected_void_std_string_Destroy() to free it when you're done using it.

calculates distances with the sign obtained from generalized winding number in each point from a three-dimensional grid; if sqr(res) < minDistSq or sqr(res) >= maxDistSq, then NaN is returned for such point

dims	dimensions of the grid

MR_IFastWindingNumberByParts_Destroy()

MRC_API void MR_IFastWindingNumberByParts_Destroy

(

const MR_IFastWindingNumberByParts *

_this

)

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

MR_IFastWindingNumberByParts_DestroyArray()

MRC_API void MR_IFastWindingNumberByParts_DestroyArray

(

const MR_IFastWindingNumberByParts *

_this

)

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

MR_IFastWindingNumberByParts_OffsetMutablePtr()

MRC_API MR_IFastWindingNumberByParts * MR_IFastWindingNumberByParts_OffsetMutablePtr	(	MR_IFastWindingNumberByParts *	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_IFastWindingNumberByParts_OffsetPtr()

MRC_API const MR_IFastWindingNumberByParts * MR_IFastWindingNumberByParts_OffsetPtr	(	const MR_IFastWindingNumberByParts *	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.
