Wraps a group of ndarrays into a single virtual ndarray
This should make it easy when dealing with chunked grids or voxel volumes to compare neighboring chunks.
Note however there is a performance hit in getting/setting values with this module. This could hopefully become less significant with code generation, but I'd like to wait until it's necessary before trying it.
npm install ndarray-group
dims specifies the dimensions of the group (by array as opposed to elements),
[2, 2]: Takes four ndarrays and returns a wrapper twice as high and wide as each child.
[3, 3, 3]: Takes 27 ndarrays, this time thrice as large.
[2, 1, 1]: Takes 2 ndarrays, twice as large on the X axis but otherwise the same.
arrays is a list of ndarrays. Each array must be the same shape, and the
list must be the correct length to fill the proxy ndarray.
Arrays should be sorted in ascending order by axis, e.g.
var group = require'ndarray-group'var fill = require'ndarray-fill'var chunks =for var z = 0; z < 3; z += 1for var y = 0; y < 3; y += 1for var x = 0; x < 3; x += 1chunkspushzeros50 50var grouped = group3 3 3 chunksfillgroupedreturn groupedgetx y z + 1
