Creating a CubeGeometry equivilent using CSS3DRenderer

问题

I am looking for sample code, that would show how one can create a cube (similar to THREE.CubeGeometry) in ThreeJS using CSS3DRenderer. Something like below

var my_cube = new **CSS3dCubeGeometry**( cube_width, cube_height, cube_depth)

var object = new THREE.CSS3DObject( my_cube );

scene.add( object );

THREE.CSS3DObject doesn't exist and I am looking for a potential implementation of it.

回答1:

You can create a cube with CSS3DRenderer like so:

// params
var r = Math.PI / 2;
var d = 50;
var pos = [ [ d, 0, 0 ], [ -d, 0, 0 ], [ 0, d, 0 ], [ 0, -d, 0 ], [ 0, 0, d ], [ 0, 0, -d ] ];
var rot = [ [ 0, r, 0 ], [ 0, -r, 0 ], [ -r, 0, 0 ], [ r, 0, 0 ], [ 0, 0, 0 ], [ 0, 0, 0 ] ];

// cube
var cube = new THREE.Object3D();
scene.add( cube );

// sides
for ( var i = 0; i < 6; i ++ ) {

    var element = document.createElement( 'div' );
    element.style.width = '100px';
    element.style.height = '100px';
    element.style.background = new THREE.Color( Math.random() * 0xffffff ).getStyle();
    element.style.opacity = '0.50';

    var object = new THREE.CSS3DObject( element );
    object.position.fromArray( pos[ i ] );
    object.rotation.fromArray( rot[ i ] );
    cube.add( object );

}
