We version objects at their finest granularity, to make repositories smaller and to allow artists to work concurrently on the same object. In this paper, we present a practical version control system for 3D scenes comprised of shapes, materials, textures, and animations, combined together in scene graphs. For 3D environments though, version control is still an open problem due to the heterogeneous data of 3D scenes and their size. Version control systems are the foundation of collaborative workflows for text documents.

We release 3DFlow as open source for artists to showcase their work and release all our datasets so other researchers can improve upon our work. Furthermore, 3DFlow is independent of the modeling software used because it requires only mesh snapshots, and uses the additional information only for optional overlays. We tested 3DFlow with a large set of inputs using a variety of mesh editing techniques, from digital sculpting to low-poly modeling, and found 3DFlow performed well for all. The output is enhanced by highlighting edited regions and, if provided, overlaying visual annotations to indicated the artist's work, e.g. 3DFlow takes as input a sequence of meshes and outputs a visualization of the workflow summarized at any level of detail. In this paper, we present 3DFlow, an algorithm that computes continuous summarizations of mesh editing workflows. For a variety of reasons, artists are interested in sharing not just their final mesh but also their whole workflow, though the common media for sharing has limitations. Mesh editing software is improving, allowing skilled artists to create detailed meshes efficiently.
