r03ert0 / make-a-box.js

Created July 22, 2017 19:31

Draw a box with triangles in three.js

	// the box geometry to initialise
	var box=new THREE.Geometry();

	// the trick to make all faces: vectors i, j and k have the coordinates of the triangles in the box
	var i="011010111111100101000000001011110100".split('').map(c=>(c=='0')?0:1),
	j="000000011010111111100101011010011010".split('').map(c=>(c=='0')?0:1),
	k="001011001011001011001011000000111111".split('').map(c=>(c=='0')?0:1);

	// this function multiplies each of the coordinates by a transformation matrix that turns them
	// into an arbitrary box
