javascript - 如何在Three.JS中的一个BufferGeometry中合并两个BufferGeometries？

如何在ThreeJS中的一个THREE.BufferGeometry中合并两个缓冲区几何？

var modelGeometry = null;

geometry = new THREE.CylinderGeometry( 10, 10, 10 );

if (modelGeometry == null)
{
    modelGeometry = new THREE.BufferGeometry().fromGeometry(geometry);
    console.log(modelGeometry);
}

bufGeometry = new THREE.SphereBufferGeometry( 20 , 20, 20 );

var mesh = new THREE.Mesh( bufGeometry, material );

modelGeometry.merge(mesh.geometry, mesh.matrix);

对modelGeometry不做任何事情。如何合并这些几何形状正确？

最佳答案

在BufferGeometry上奇怪地调用merge()给了我一些错误，但是有一种解决方法:

合并两个Geometry对象；

转换为BufferGeometry;

添加到网格

这是为我工作的东西:

    var modelGeometry = new THREE.Geometry();

    cylGeometry = new THREE.CylinderGeometry( 10, 10, 10 );

    // if (modelGeometry == null)
    // {
    //     modelGeometry = new THREE.BufferGeometry().fromGeometry(geometry);
    //     console.log(modelGeometry);
    // }

    modelGeometry.merge(cylGeometry);

    sphereGeometry = new THREE.SphereGeometry( 20 , 20, 20 );

    modelGeometry.merge(sphereGeometry);

    bufGeometry = new THREE.BufferGeometry().fromGeometry(modelGeometry);

    var mesh = new THREE.Mesh( bufGeometry, material );

    scene.add(mesh);
