    Project mention: Ask HN: What is your new year's resolution? | news.ycombinator.com | 2023-01-01

    Sort of.

    1. I want to start with working through applying shaders to a 3d scene using the Panda3d library (https://github.com/panda3d/panda3d) . This repo covers that: https://github.com/lettier/3d-game-shaders-for-beginners.

    2. Create a simple, custom, graphics-only (no collisions / physics) game engine using Entt (https://github.com/skypjack/entt) and Panda3d. The engine would rely mostly on simple inputs, like mouse clicks, and 3d graphics.

    3. Configure clangd to warn on features outside C++11 then refactor both projects (1 & 2)

    4. Run experiments on the game engine while working through the Vulkan book: https://raw.githubusercontent.com/Overv/VulkanTutorial/maste...

  • allsky

    A Raspberry Pi operated Wireless Allsky Camera

    Project mention: A couple of all-sky camera questions | reddit.com/r/AskAstrophotography | 2022-05-31

    I have been building an all-sky camera for my club, based on a Raspberry Pi 3B+ and the Raspberry Pi HQ camera. I chose the color RPi HQ camera over a monochrome ZWO ASI 120MM because of price, and because the performance was "good enough" for our intended purpose - letting club members see at a glance whether it was worth driving to the observing field. The ZWO performed better than the RPi HQ in that its sensor was more sensitive and it produced a similarly illuminated image in less time, but it would have broken the budget. The allsky software I'm using only supports ZWO cameras and the Raspberry Pi HQ camera.
