bool HeightfieldChunker::ProcessGrid	(	const vtElevationGrid *	grid,
		FILE *	out,
		int	tree_depth,
		float	base_max_error,
		float	vertical_scale,
		float	input_vertical_scale,
		bool	progress_callbackint = NULL
	)

Generate LOD chunks from the given heightfield.

tree_depth determines the depth of the chunk quadtree.

base_max_error specifies the maximum allowed geometric vertex error, at the finest level of detail.

Spacing determines the horizontal sample spacing for bitmap heightfields only.
