Project mention: Redot Engine – Multi-platform 2D and 3D game engine | news.ycombinator.com | 2024-10-01
What is the difference between "Redot" and Godot?
The README for this GitHub contains the same info as the official Godot repo [1], so it's not clear what this fork does differently or changes.

3d-game-shaders-for-beginners
🎮 A step-by-step guide to implementing SSAO, depth of field, lighting, normal mapping, and more for your 3D game.
This is a great series if you’re looking for a tutorial. https://lettier.github.io/3d-game-shaders-for-beginners/inde...

Bullet
Bullet Physics SDK: real-time collision detection and multi-physics simulation for VR, games, visual effects, robotics, machine learning etc.
For typical game physics engines... not that much. Math libraries like Eigen or Blaze use lots of template metaprogramming techniques under the hood that can help when you're doing large batched matrix multiplications (since it can remove temporary allocations at compile-time and can also fuse operations efficiently, as well as applying various SIMD optimizations), but it doesn't really help when you need lots of small operations (with mat3 / mat4 / vec3 / quat / etc.). Typical game physics engines tend to use iterative algorithms for their solvers (Gauss-Seidel, PBD, etc...) instead of batched "matrix"-oriented ones, so you'll get less benefits out of Eigen / Blaze compared to what you typically see in deep learning / scientific computing workloads.
The codebases I've seen in many game physics engines seem to all roll their own math libraries for these stuff, or even just use SIMD (SSE / AVX) intrinsics directly. Examples: PhysX (https://github.com/NVIDIA-Omniverse/PhysX), Box2D (https://github.com/erincatto/box2d), Bullet (https://github.com/bulletphysics/bullet3)...

Project mention: Using Jolt with flecs & Dear ImGui: Game Physics Introspection | dev.to | 2024-04-17
EnTT is a popular alternative to flecs for C++, which has different performance/memory characteristics.
-
GameNetworkingSockets
Reliable & unreliable messages over UDP. Robust message fragmentation & reassembly. P2P networking / NAT traversal. Encryption.
Steam does have a NAT traversal/punchthrough service too. It's apparently usable without Steam according to their README on https://github.com/ValveSoftware/GameNetworkingSockets but honestly the only easy to use implementation I know is in Facepunch.Steamworks which requires a SteamID to initialize

o3de
Open 3D Engine (O3DE) is an Apache 2.0-licensed multi-platform 3D engine that enables developers and content creators to build AAA games, cinema-quality 3D worlds, and high-fidelity simulations without any fees or commercial obligations.

Project mention: Endless Sky: Open-Source Space Exploration, Trading, and Combat Game | news.ycombinator.com | 2024-09-29
-
Early this year, I did game development with Love2D engine (relies on Lua language) and was inspired by its approach, so decided to make something similar myself for the competition.

Panda3D
Powerful, mature open-source cross-platform game engine for Python and C++, developed by Disney and CMU
I have developed a simple simulator [0] to estimate the theoretical power received by the target for a given hardware configuration:
- the global position on the planet
- the date and time
- the size and position of some background elements
- the number, size and position of the panels in the grid
The solar power estimation uses :
- the Python code provided in this article [1] to estimate position of the sun (thank you John Clark Craig)
- the simplified formula [2] to estimate the direct insolation from the sun position
- a custom light projection implemented using Panda3D game engine [3]
