Neural Radiance Fields (NeRF) mark a pivotal advancement in 3D scene reconstruction and real-time rendering. By integrating deep learning with volumetric rendering, NeRF facilitates the creation of highly realistic novel views from limited 2D image inputs. This technology is vital for fields like medical imaging, augmented and virtual reality (AR/VR), and robotics, where precise scene reconstruction and efficient performance are critical. Unlike conventional 3D modeling approaches, which often face issues with scalability, view limitations, and visual fidelity, NeRF and its evolved iterations address these drawbacks through innovative architectures and optimization strategies. This review provides an in-depth exploration of NeRF, covering its theoretical underpinnings, core challenges, and subsequent improvements. We examine recent developments, including MultiPlaneNeRF, Neural Ray- Surface Mapping (NRSM), and self-supervised frameworks for robotics, highlighting how these advancements enable faster, more adaptable, and scalable 3D modeling. Additionally, the paper investigates NeRF’s real-world applications, identifies persistent obstacles ,and suggests potential avenues for future research, such as dynamic scene modeling and optimization for mobile devices. By synthesizing and critically evaluating existing studies, this review seeks to be a valuable resource for researchers and professionals aiming to engage with and advance this groundbreaking field.
