K-Lens One – A Light Field Lens that captures RGB + Depth
www.newsshooter.com/2021/10/31/klens-one-a-light-field-lens-that-captures-rgb-depth/
A mirror system (Image Multiplier) in the K|Lens splits the light rays into 9 separate images that are mapped on the camera sensor. All 9 of these images have slightly different perspectives. The best way to picture it is if you imagine using 9 separate cameras in a narrow array at the same time.

Floating point precision and errors in 3D production
https://blog.demofox.org/2017/11/21/floating-point-precision
https://www.h-schmidt.net/FloatConverter/IEEE754.html
The challenge with precision limits in production is tightly connected to the context of the assets, camera and procedural requirements the render scene needs to support.
For example a far away camera chasing a plane may not reveal issues that the same scene may show with a far away camera’s closeup of a displaced water drop on the plane’s windshield.
This is a rough example, but it helps putting things in perspective.Always best testing for specific patterns or targets within a given setup.

Debayer – A free command line tool to convert camera raw images into scene-linear exr
https://github.com/jedypod/debayer
The only required dependency is oiiotool. However other “debayer engines” are also supported.
- OpenImageIO – oiiotool is used for converting debayered tif images to exr.
- Debayer Engines
- RawTherapee – Powerful raw development software used to decode raw images. High quality, good selection of debayer algorithms, and more advanced raw processing like chromatic aberration removal.
- LibRaw – dcraw_emu commandline utility included with LibRaw. Optional alternative for debayer. Simple, fast and effective.
- Darktable – Uses darktable-cli plus an xmp config to process.
- vkdt – uses vkdt-cli to debayer. Pretty experimental still. Uses Vulkan for image processing. Stupidly fast. Pretty limited.
