point-cluster Build Statusexperimental

Point clustering for 2D spatial indexing. Incorporates optimized quad-tree data structure.

API

ids = cluster(points, options?)

Create index for the set of 2d points based on options.

  • points is an array of [x,y, x,y, ...] or [[x,y], [x,y], ...] coordinates.
  • ids is Uint32Array with point ids sorted by zoom levels, suitable for WebGL buffer, subranging or alike.
  • options
OptionDefaultDescription
bounds'auto'Data range, if different from points bounds, eg. in case of subdata.
depth256Max number of levels. Points below the indicated level are grouped into single level.
output'array'Output data array or data format. For available formats see dtype.

result = ids.range(box?, options?)

Get point ids from the indicated range.

  • box can be any rectangle object, eg. [l, t, r, b], see parse-rect.
  • options
OptionDefaultDescription
lodfalseMakes result a list of level details instead of ids, useful for obtaining subranges to render.
px0Min pixel size in data dimension (number or [width, height] couple) to search for, to ignore lower levels.
levelnullMax level to limit search.
