Comparative Evaluation of 3D Reconstruction Methods for Immersive Visualization of Laboratory Objects

A new comparison of 3D reconstruction methods for immersive lab visualization found that NeRF-based capture produced the most consistently high-fidelity holographic models across a set of common laboratory objects. The study pitted photogrammetry, NeRF, Gaussian splatting, and LiDAR against each other, then had graduate students rate the results for shape, color, texture, and visual defects in a repeated-measures setup.

The biggest takeaway for developers building educational XR content is that the hard cases are still the hard cases: transparent, reflective, and low-texture objects were where NeRF held up best. Across the board, shape and color were reproduced more reliably than texture, which is a useful reminder that “looks right in headset” is still constrained by material properties and capture method, not just renderer quality.

The work is aimed at practical AR/MR learning workflows, not just academic benchmarking. The authors frame these reconstructions as a way to support pre-lab preparation, spatial reasoning, and student engagement, which makes the results relevant to anyone shipping immersive training, simulation, or product-visualization tools where fidelity and turnaround time both matter.

For teams choosing a reconstruction stack, the implication is straightforward: if the target assets include glass, shiny surfaces, or sparse detail, NeRF may be the safer default for visual realism. The exact production tradeoffs versus photogrammetry, splatting, and LiDAR will still depend on capture budget, runtime constraints, and how much post-processing your pipeline...
