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
