一、基本介绍
Revit（RVT）和3D Tiles是两种不同类型的三维数据格式，主要用于建筑、工程和地理信息系统（GIS）领域。
二、和glb关系
转换工具：三维模型：人工建模模型转为3DTiles格式 | Mars3D开发教程
3D Tiles 支持多种几何格式，包括：
Batched 3D Model (b3dm)：这是最常用的格式，可以嵌入 GLB 或者 GLTF 模型。
Instanced 3D Model (i3dm)：用于存储带有多个实例的模型，每个实例可以是一个 GLB 或 GLTF 模型。
Point Cloud (pnts)：用于存储点云数据。
Composite (cmpt)：可以组合多个其他格式的 Tiles。
具体来说，Batched 3D Model (b3dm) 格式中，GLB 模型可以作为它的 payload（有效载荷）来存储。这样，3D Tiles 可以在网络传输和渲染时高效地利用 GLB 模型。
Batched 3D Model (b3dm) 是 3D Tiles 规范中的一种格式，专门用于在大规模 3D 场景中批量存储和传输3D模型。
