I'm following the advice in Create a concave halfsphere with Three.js to create a halfsphere in Three.js that I plan on mapping some fisheye video to. An example (with lens cap on) is here.
I'm just trying to get the sphere to show first and it disappears whenever I try and turn it into a half sphere.
See the code at http://codepen.io/bknill/pen/vXBWGv.
var geometry = new THREE.SphereGeometry(5000,16,16, Math.PI/2, Math.PI*2, 0, Math.PI);
var material = new THREE.MeshBasicMaterial({ color: 0x2980b9});
material.side = THREE.BackSide;
var sphere = new THREE.Mesh(geometry, material);
scene.add(sphere);
How can I get this halfsphere to show up?
