Seurat

Seurat is a scene simplification technology designed to process very complex 3D scenes into a representation that renders efficiently on mobile 6DOF VR systems.

Seurat works by taking advantage of the fact that VR scenes are typically viewed from within a limited viewing region (the box on the left below), and leverages this to optimize the geometry and textures in your scene.

It takes RGBD images (color and depth) as input and generates a textured mesh, targeting a configurable number of triangles, texture size, and fill rate, to simplify scenes beyond what traditional methods can achieve.

Seurat is available as an open source project on GitHub, and includes plugin support for generating depth images for scenes in both Unity and Unreal.
