Functions
FloatGrid	MR::meshToLevelSet (const MeshPart &mp, const AffineXf3f &xf, const Vector3f &voxelSize, float surfaceOffset=3, ProgressCallback cb={})
FloatGrid	MR::meshToDistanceField (const MeshPart &mp, const AffineXf3f &xf, const Vector3f &voxelSize, float surfaceOffset=3, ProgressCallback cb={})
void	MR::evalGridMinMax (const FloatGrid &grid, float &min, float &max)
	eval min max value from FloatGrid
Expected< VdbVolume >	MR::meshToDistanceVdbVolume (const MeshPart &mp, const MeshToVolumeParams &params={})
Expected< VdbVolume >	MR::meshToVolume (const MeshPart &mp, const MeshToVolumeParams &params={})
VdbVolume	MR::floatGridToVdbVolume (FloatGrid grid)
	fills VdbVolume data from FloatGrid (does not fill voxels size, cause we expect it outside)
FloatGrid	MR::simpleVolumeToDenseGrid (const SimpleVolume &simpleVolume, float background=0.0f, ProgressCallback cb={})
VdbVolume	MR::simpleVolumeToVdbVolume (const SimpleVolumeMinMax &simpleVolume, ProgressCallback cb={})
	set the simpleVolume.min as the background value
VdbVolume	MR::functionVolumeToVdbVolume (const FunctionVolume &functoinVolume, ProgressCallback cb={})
template<typename AccessorOrGrid>
void	MR::putSimpleVolumeInDenseGrid (AccessorOrGrid &gridAccessor, const Vector3i &minCoord, const SimpleVolume &simpleVolume, ProgressCallback cb={})
	Copy given simpleVolume into the grid, starting at minCoord Instantiated for AccessorOrGrid in { openvdb::FloatGrid::Accessor, FloatGrid, openvdb::FloatGrid }. The template is used to not include openvdb's mess into this header (forward declaring classes in openvdb is also non-trivial). When used with a Grid, multithreaded implementation of copying is used (so the function is not thread safe). When used with an Accessor, this function could be called from different threads on the same volume (provided that accessors are different, of course).
