3D + MongoDB = 3D Repo
1 like2,625 views
The document discusses the integration of 3D modeling with MongoDB for the UK construction industry's aims to reduce costs by 20% through a common data environment. It outlines features such as non-linear revision history, streamable 3D geometry, and meshes with detailed specifications of their properties. Additionally, it mentions aspects of security, user roles, and future developments such as streaming geometry from cache.
