Question

问题：

如何将N个THREE.BoxGeometry对象合并为一个THREE.BufferedGeometry？

现在我有这样的事情：

var buffer = new THREE.BufferGeometry();

            for (var i = 0; i < meshList.length; ++i) {
                var item = meshList[i];
                var geometry = <THREE.BoxGeometry>item.geometry;
                buffer.fromGeometry(geometry);
            }

            buffer.computeBoundingSphere();

            var buffer_material = new THREE.MeshPhongMaterial({
                color: 0x999999,
                specular: 0x333333,
                shininess: 50,
                side: THREE.DoubleSide,
                vertexColors: THREE.VertexColors,
                shading: THREE.SmoothShading
            });

            var buffer_mesh = new THREE.Mesh(buffer, buffer_material);
            this.Scene.add(buffer_mesh);

不幸的是，这并不完全奏效。我只看到一个盒子（而不是很多盒子）。我需要指定“位置”吗？如果是这样，我该怎么做？

谢谢！

您可以合并THREE.Geometry，然后使用如下模式将结果转换为THREE.BufferGeometry：

var geometry = new THREE.Geometry();

for ( var count = 0; count < 10; count ++ ) {

    var geo = new THREE.BoxGeometry( 5, 5, 5 );

    geo.translate( THREE.Math.randFloat( - 5, 5 ), THREE.Math.randFloat( - 5, 5 ), THREE.Math.randFloat( - 5, 5 ) );

    geometry.merge( geo );

}

geometry = new THREE.BufferGeometry().fromGeometry( geometry );

将多个BoxGeometries转换为单个BufferedGeometry
