从内部投射时,Raycast不会击中网格

Question

我已经设置了一个简单的场景,我将相机放在球体几何体内

var mat = new THREE.MeshBasicMaterial({map: THREE.ImageUtils.loadTexture('0.jpg') , overdraw:true,  color: 0xffffff, wireframe: false });
        var sphereGeo = new THREE.SphereGeometry(1000,50,50);
        var sphere = new THREE.Mesh(sphereGeo,mat);
        sphere.scale.x = -1;
        sphere.doubleSided = false;
        scene.add(sphere);

我设置了一个功能,我可以在那个球体内部环顾四周,我的观点是能够在鼠标上投射光线,击中球体并获得发生击中的坐标.我正在投射一条光线但是相交仍然是空的.

var vector = new THREE.Vector3();
      vector.set( ( event.clientX / window.innerWidth ) * 2 - 1, - ( event.clientY / window.innerHeight ) * 2 + 1, 0.5 );
      vector.unproject( camera );

      raycaster.ray.set( camera.position, vector.sub( camera.position ).normalize());

var intersects = raycaster.intersectObjects(scene.children, true);

一切都适用于测试立方体也放在我的球体内.我的问题是,你是从内部击中物体还是不击中物体是否重要？因为这是我脑海中唯一的解释.

提前致谢.

Answer 1

sphere.doubleSidedsphere.material.side = THREE.DoubleSide几年前改变了.
