Show HN: Gaussian Splat of a Strawberry (superspl.at)

Article summary

The article presents a Gaussian splat of a strawberry, created by taking 7920 photos from 90 perspectives with a Nikon Z8 camera and Laowa 180mm macro lens. The images were focus stacked and processed using the slang-splat software. The resulting splat is available for download under a CC BY license. The author also shares their setup and process for capturing the images.

What commenters say

• The strawberry's rotten underside is likely missing from the splat due to the mounting and capture process.
• The use of a needle or thread to mount the strawberry could potentially improve the capture of its underside.
• Some commenters believe that focus stacking is not a necessary preprocessing step for 3D reconstruction and that it can lead to artifacts and errors.
• The quality of the splat degrades when zoomed in, suggesting limitations to the current state of Gaussian splatting technology.
• The author's use of a rotary disk and computer-controlled capture process allows for efficient and high-quality image capture.
• There is interest in exploring the application of Gaussian splatting to microscopy and capturing smaller objects with higher levels of detail.
• The compression of Gaussian splats is an area of ongoing research and development, with multiple formats and techniques being explored.
• The mounting and rotation of the strawberry during capture is a challenging aspect of the process, and different approaches are being considered.
