  Reconstructing detailed 3D scenes from single-view images remains a
challenging task due to limitations in existing approaches, which primarily
focus on geometric shape recovery, overlooking object appearances and fine
shape details. To address these challenges, we propose a novel framework for
simultaneous high-fidelity recovery of object shapes and textures from
single-view images. Our approach utilizes the proposed Single-view neural
implicit Shape and Radiance field (SSR) representations to leverage both
explicit 3D shape supervision and volume rendering of color, depth, and surface
normal images. To overcome shape-appearance ambiguity under partial
observations, we introduce a two-stage learning curriculum incorporating both
3D and 2D supervisions. A distinctive feature of our framework is its ability
to generate fine-grained textured meshes while seamlessly integrating rendering
capabilities into the single-view 3D reconstruction model. This integration
enables not only improved textured 3D object reconstruction by 27.7% and 11.6%
on the 3D-FRONT and Pix3D datasets, respectively, but also supports the
rendering of images from novel viewpoints. Beyond individual objects, our
approach facilitates composing object-level representations into flexible scene
representations, thereby enabling applications such as holistic scene
understanding and 3D scene editing. We conduct extensive experiments to
demonstrate the effectiveness of our method.
