Function Documentation

morton_code_set_from_positions() [1/2]

template<class Tmorton, class Tvec, u32 dim>

MortonCodeSet< Tmorton, Tvec, dim > shamtree::morton_code_set_from_positions	(	const sham::DeviceScheduler_ptr &	dev_sched,
		shammath::AABB< Tvec >	bounding_box,
		sham::DeviceBuffer< Tvec > &	pos_buf,
		u32	cnt_obj,
		u32	morton_count )

Generate a set of Morton codes from a buffer of positions.

Parameters

dev_sched	The device scheduler for the computation
bounding_box	The bounding box containing all positions
pos_buf	The device buffer containing the positions
cnt_obj	The count of objects in the buffer
morton_count	The count of Morton codes in the output set (can be different from cnt_obj)

If morton_count > cnt_obj, the extra Morton codes will be set to an error code larger than any valid Morton code.

Returns

The MortonCodeSet, containing the bounding box, the count of objects and the Morton codes. The Morton codes are sorted in ascending order.

Note

morton_count >= cnt_obj

morton_code_set_from_positions() [2/2]

template<class Tmorton, class Tvec, u32 dim>

MortonCodeSet< Tmorton, Tvec, dim > shamtree::morton_code_set_from_positions	(	const sham::DeviceScheduler_ptr &	dev_sched,
		shammath::AABB< Tvec >	bounding_box,
		sham::DeviceBuffer< Tvec > &	pos_buf,
		u32	cnt_obj,
		u32	morton_count,
		sham::DeviceBuffer< Tmorton > &&	cache_buf_morton_codes )

Generate a set of Morton codes from a buffer of positions.

Parameters

dev_sched	The device scheduler for the computation
bounding_box	The bounding box containing all positions
pos_buf	The device buffer containing the positions
cnt_obj	The count of objects in the buffer
morton_count	The count of Morton codes in the output set (can be different from cnt_obj)
cache_buf_morton_codes	A device buffer to be reused for the output Morton codes

If morton_count > cnt_obj, the extra Morton codes will be set to an error code larger than any valid Morton code.

Returns

The MortonCodeSet, containing the bounding box, the count of objects and the Morton codes. The Morton codes are sorted in ascending order.

Note

morton_count >= cnt_obj
