snap-points-2d
Advanced tools
Runs iterative snap rounding on a set of 2D coordinates to produce a hierarchical level of detail for optimizing online rendering of huge 2D plots.
npm i snap-points-2d
var hlod = require('snap-points-2d')(points, ids, [, bounds])Reorders the points hierarchically such that those which are drawn at the same pixel coordinate are grouped together.
points is an array of 2*n valuesids is an array which gets the reordered index of the pointsbounds is an optional array of 4 values giving the bounding box of the pointsReturns An array of LOD scales. Each record is an object with the following properties:
pixelSize the pixel size of this level of detail in data unitsoffset the offset of this lod within the output arraycount the number of items in the lodNote the points in output are rescaled to the unit box [0,1]x[0,1] and the array points in the input is shuffled during execution.
