  Simultaneous reconstruction of geometry and reflectance properties in
uncontrolled environments remains a challenging problem. In this paper, we
propose an efficient method to reconstruct the scene's 3D geometry and
reflectance from multi-view photography using conventional hand-held cameras.
Our method automatically builds a virtual scene in a differentiable rendering
system that roughly matches the real world's scene parameters, optimized by
minimizing photometric objectives alternatingly and stochastically. With the
optimal scene parameters evaluated, photo-realistic novel views for various
viewing angles and distances can then be generated by our approach. We present
the results of captured scenes with complex geometry and various reflection
types. Our method also shows superior performance compared to state-of-the-art
alternatives in novel view synthesis visually and quantitatively.
