I'm trying to create a three.js scene with a cubemap panorama background and a few .obj files with .mtl textures placed in the scene. However, I'm receiving this WebGL error that I can't figure out the source of:
THbindTexture: textures can not be used with multiple targets
Does anyone know what could possibly be going wrong? Here is the relevant code:
var camera, cubeCamera, scene, object, renderer;
var cube, sphere, torus;
var fov = 70,
isUserInteracting = false,
onMouseDownMouseX = 0, onMouseDownMouseY = 0,
lon = 0, onMouseDownLon = 0,
lat = 0, onMouseDownLat = 0,
phi = 0, theta = 0;
var skyLoader = new THREE.TextureLoader();
skyLoader.load( 'pano.jpg', function ( texture ) {
texture.mapping = THREE.UVMapping;
init( texture );
animate();
} );
function init( texture ) {
camera = new THREE.PerspectiveCamera( fov, window.innerWidth / window.innerHeight, 1, 1000 );
scene = new THREE.Scene();
var ambient = new THREE.AmbientLight( 0x444444 );
scene.add( ambient );
var directionalLight = new THREE.DirectionalLight( 0xffeedd );
directionalLight.position.set( 0, 0, 1 ).normalize();
scene.add( directionalLight );
var mesh = new THREE.Mesh( new THREE.SphereGeometry( 500, 60, 40 ), new THREE.MeshBasicMaterial( { map: texture } ) );
mesh.scale.x = -1;
scene.add( mesh );
renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setPixelRatio( window.devicePixelRatio );
renderer.setSize( window.innerWidth, window.innerHeight );
cubeCamera = new THREE.CubeCamera( 1, 1000, 256 );
scene.add( cubeCamera );
document.body.appendChild( renderer.domElement );
document.addEventListener( 'mousedown', onDocumentMouseDown, false );
document.addEventListener( 'mousewheel', onDocumentMouseWheel, false );
document.addEventListener( 'MozMousePixelScroll', onDocumentMouseWheel, false);
window.addEventListener( 'resize', onWindowResized, false );
onWindowResized( null );
var loader = new THREE.OBJLoader();
loader.load( 'nsa_sanantonio.obj', function ( object ) {
object.traverse( function ( child ) {
if ( child instanceof THREE.Mesh ) {
child.material.envMap = texture;
// add any other properties you want here. check the docs.
}
} );
scene.add( object );
} );
}
function onWindowResized( event ) {
renderer.setSize( window.innerWidth, window.innerHeight );
camera.projectionMatrix.makePerspective( fov, window.innerWidth / window.innerHeight, 1, 1100 );
}
function onDocumentMouseDown( event ) {
event.preventDefault();
onPointerDownPointerX = event.clientX;
onPointerDownPointerY = event.clientY;
onPointerDownLon = lon;
onPointerDownLat = lat;
document.addEventListener( 'mousemove', onDocumentMouseMove, false );
document.addEventListener( 'mouseup', onDocumentMouseUp, false );
}
function onDocumentMouseMove( event ) {
lon = ( event.clientX - onPointerDownPointerX ) * 0.1 + onPointerDownLon;
lat = ( event.clientY - onPointerDownPointerY ) * 0.1 + onPointerDownLat;
}
function onDocumentMouseUp( event ) {
document.removeEventListener( 'mousemove', onDocumentMouseMove, false );
document.removeEventListener( 'mouseup', onDocumentMouseUp, false );
}
function onDocumentMouseWheel( event ) {
// WebKit
if ( event.wheelDeltaY ) {
fov -= event.wheelDeltaY * 0.05;
// Opera / Explorer 9
} else if ( event.wheelDelta ) {
fov -= event.wheelDelta * 0.05;
// Firefox
} else if ( event.detail ) {
fov += event.detail * 1.0;
}
camera.projectionMatrix.makePerspective( fov, window.innerWidth / window.innerHeight, 1, 1100 );
}
function animate() {
requestAnimationFrame( animate );
render();
}
function render() {
var time = Date.now();
lon += .15;
lat = Math.max( - 85, Math.min( 85, lat ) );
phi = THREE.Math.degToRad( 90 - lat );
theta = THREE.Math.degToRad( lon );
camera.position.x = 100 * Math.sin( phi ) * Math.cos( theta );
camera.position.y = 100 * Math.cos( phi );
camera.position.z = 100 * Math.sin( phi ) * Math.sin( theta );
camera.lookAt( scene.position );
cubeCamera.updateCubeMap( renderer, scene );
renderer.render( scene, camera );
}
I don't understand how two textures are being applied at once. I got the Objloader code from here. But it also doesn't work with the normal obj/stl loader. I have a demo on my website at http://www.zakziebell.com/nsa (you'll see that my model is black)
