Detailed Description

template<class morton_t, class pos_t, u32 dim>
class RadixTreeMortonBuilder< morton_t, pos_t, dim >

Helper class to build morton codes.

Todo:

use Tvec Tmorton and infer dimension from it

Template Parameters

morton_t	the morton type used
pos_t	the position type (vector)
dim	dimensionality

build morton code table for the tree

index map detail : (the given index correspong to the one of an original position)

Parameters

queue	the SYCL queue to run on
bounding_box	bounding box of the corresponding input coordinates
pos_buf	buffer of position to build morton codes from
cnt_obj	number of position given in the buffer
out_buf_morton	resulting morton buffer (sorted in morton ordering)
out_buf_particle_index_map	resulting index map
