Centers vertices around a point.

Demo

npm install geo-center

var dragon = require('stanford-dragon/3')
var center = require('geo-center')

dragon.positions = center(dragon.positions, {
  center: [0,0,0]
})

var center = require('geo-center')

Returns a copy of positions centered around opts.center.

positions is the vertex array for your mesh. It can be any of:

• Flat array [1,2,3,4,5,6]
• Array of arrays [[1,2,3], [4,5,6]]
• TypedArray new Float32Array([1,2,3,4,5,6])
• Array of TypedArrays [new Float32Array([1,2,3]), new Float32Array([4,5,6])]
• ndarray ndarray(new Float32Array([1,2,3,4,5,6]))

opts is an object that can have the following properties:

• center is the point you want your mesh centered upon. Defaults to [0,0,0].
