Checks if an axis aligned bounding box intersects a camera frustum.
npm install box-frustumbox-frustum
===========
A function to test if an axis aligned bounding box interesects the camera frustum.
Usage/Installation
==================
First, pull this in via npm:
npm install box-frustum
Then you can do a frustum test like this:
require("box-frustum")(
[1, 0, 0, 0,
0, 1, 0, 0,
0, 0, 1, 0,
0, 0, 0, 1],
[[-1,-1,-1], [1,1,1]])
Which will check if axis-aligned bounding box from (-1,-1,-1) to (1,1,1) intersects the frustum for the unit matrix.
require("box-frustum")(m, box)
--------------------------------
module.exports implements the frustum test. It takes two arguments:
* m is an array of 16 float values representing the homogeneous clip coordinate matrix for the camera in row major order.
* box = [lo, hi] is an array of two length 3 arrays giving the bounds for the axis aligned bounding.
Results: true if the box intersects the camera frustum, flase otherwise.
