- Gaussian splats are blurry ellipsoids optimized to match input photos, creating viewable 3D photographs from any angle.
- Macro subjects like insects, with their complex textures, are ideal for splat creation.
- Macro photography's shallow depth of field complicates splat creation, requiring focus stacking for sharpness.
- Focus stacking combines multiple images at different focal points into one sharp photo, with 16 images per stack used here.
- The setup involved a small aperture (f/18) to maximize depth of field, with diffraction minimized in post-processing.
- A rotary disk and boom arm were used to capture the insect from 111 perspectives, with automated and manual adjustments.
- A total of 1776 photos were taken over four hours, limited by the camera's buffer capacity.
- Post-processing included batch focus-stacking, color correction, and background masking before training the splat model.
- The final splat required minimal retouching to remove the mounting and is viewable in 3D online.
