3D 通过 Java 进行格式转换
无需安装任何 3D 建模和渲染软件即可转换 3D 文件格式以构建跨平台 Java 应用程序。
对于创建、编辑、操作和保存 3D 图形应用程序，Java 3D API 提供了执行此类功能的高级方法，而无需安装任何 3D 建模和渲染软件。很少有构建不同 3D 几何形状的网格、创建 3D 场景文件、在 Cube 上设置法线或 UV、格式化元素、添加动画属性等等。
将 3D 文件转换为不同格式
转换过程很简单。只需使用加载源 3D 文件 场景类 .由于场景是具有节点、几何、纹理、材质、动画、姿势、子场景等的顶级对象。创建相关的 保存选项 例如 AmfSaveOptions、ColladaSaveOptions、Discreet3dsSaveOptions、DracoSaveOptions、FbxSaveOptions、GltfSaveOptions、RvmSaveOptions、StlSaveOptions、U3dSaveOptions 等，并相应地设置属性。最后使用输出文件调用 save 方法并创建目标格式保存选项对象。此外，使用 API 程序员甚至可以将 3D 场景保存为 HTML。
