Hexels use hexagonal primitives for more efficient 3D scene rendering
Original title: Honeycomb-Surfels: Compact Hexagonal Primitives for Efficient Scene Rendering and Reconstruction
Across 34 scenes, Hexels beat memory-matched 2DGS by 4.53-7.38 dB PSNR with lower training VRAM.
The paper introduces Hexels, planar hexagonal surface elements with a first-order spatial color field for novel-view synthesis and reconstruction. On 34 scenes they improve PSNR over memory-matched 2DGS by 4.53-7.38 dB while using less training VRAM. Surface error falls 28.9% versus memory-matched 2DGS on 15 DTU scans, and mean F1 reaches 34.38% on six Tanks and Temples scenes, versus 31.72% for 2DGS.
- Per primitive, Hexels beat 2DGS by up to 4.74 dB.
- Those comparisons also report 2.31 times faster frames per second.
- Hexels improve 2D image representation compared with Image-GS.
- Unconstrained settings still show quality-memory trade-offs.
From the original article
1 min read at arxiv.orgNovel view synthesis and 3D reconstruction have advanced rapidly with radiance fields and splatting, yet their memory and computational demands limit their use in resource-constrained settings. We introduce Hexels: novel planar hexagonal surface elements with a first-order spatial color field for efficient 3D scene and 2D image representation.
