A flexible system for generating greedy meshes of ndarrays.
var compileMesher = require("greedy-mesher")
var mesher = compileMesher({
extraArgs: 1,
order: [1, 0],
append: function(lo_x, lo_y, hi_x, hi_y, val, result) {
result.push([[lo_x, lo_y], [hi_x, hi_y]])
}
})
var test_array = require("ndarray-pack")(
[[0, 2, 0, 0],
[0, 1, 1, 0],
[0, 1, 1, 0],
[0, 0, 0, 0]])
var result = []
mesher(test_array, result)
console.log(result);
// outputs: [ [ [ 1, 0 ], [ 2, 1 ] ], [ [ 1, 1 ], [ 3, 3 ] ] ]
npm install greedy-mesher
require("greedy-mesher")(options)
This routine generates a greedy mesher for a given order and list of closures
order
An array representing the order in which to mesh the input.extraArgs
The number of optional arguments to pass to each closure.skip(a,...)
A closure which tests if the given voxel should be skipped. (Default: skips 0)merge(a,b,...)
A closure which tests if voxels a and b can be merged in the mesh. (Default: checks if voxels are equal)append(lo0, lo1, ..., lon, hi0, hi1, ..., hin, val, ...)
