javascript - THREE.js translation/position weirdness -
i'm trying generate random planes in random position in screen , of random size. problem have don't understand set.position values. representing? tried search every answer couldn't find. here's code planes: var planes = []; (i = 0; < 20; i++) { var geometry = new three.planegeometry(sizewidth*((randomso(1,20)*0.00001)), sizeheight*((randomso(1,10)*0.0001))); var material = new three.meshbasicmaterial( {color: 0x00ff00}); var plane = new three.mesh(geometry, material); plane.drawmode = three.trianglesdrawmode; plane.position.set(-10+i, 0, 0); scene.add(plane); planes[i] = plane; } the x-co-ordinate in above example isn't how i'd want testing. work according screensize, each plane locate in random % of width , height. width of screen 1280 , when set the x co-ordinate let's -20 it's out of screen. should set z co-ordinate of camera differently? don't understand position co-ordinates in :-(
