SpecTRe-GS: Modeling Highly Specular Surfaces with Reflected Nearby Objects by Tracing Rays in 3D Gaussian Splatting

Figure 1 . Our SpecTRe-GS effectively captures the appearance of reflectors with highly specular surfaces, even in the presence of nearby objects. In the real-world scene shown above, it performs favorably against previous methods [13, 15, 30, 39, 42] , both visually (as the highlighted reflections within the insets) and quantitatively (with PSNR values within the reflective region annotated in the corners).
