Init() [1/4]

MAXON_METHOD Result<Bool> Init	(	PolygonObject *	polyObject,
		Int32	voxelResolution,
		Int32	minResolution,
		BaseArray< Range< Vector >> &	polyRanges,
		const Vector *	pointOverride = nullptr,
		Bool	precise = false
	)

Initializes the voxelization with a polygon object.

Parameters

[in]	polyObject	Pointer to the polygon object to be added to the voxelization.
[in]	voxelResolution	The voxel resolution of the largest dimension.
[in]	minResolution	The minimal resolution of either dimension.
[out]	polyRanges	Calculated bounding boxes for every polygon.
[in]	pointOverride	Override option for the polygon points. If not nullptr, these points will be used for the polygon vertices.
[in]	precise	If true, only the voxels touching a polygon will hold the specific polygon index. If false, all voxels touching the polygon AABB will hold the polygon index.

Returns

True if the voxelization was properly initialized, false otherwise.

		const Vector *	pointOverride = nullptr
	)

Initializes the voxelization with a polygon object.

Parameters

[in]	polyObject	Pointer to the polygon object to be added to the voxelization.

[in]	voxelResolution	The voxel resolution of the largest dimension.
[in]	minResolution	The minimal resolution of either dimension.
[out]	polyRanges	Calculated bounding boxes for every polygon.
[in]	pointOverride	Override option for the polygon points. If not nullptr, these points will be used for the polygon vertices.

Returns

True if the voxelization was properly initialized, false otherwise.

Init() [3/4]
