  • µWebSockets

    Simple, secure & standards compliant web server for the most demanding of applications

    Project mention: Nuklear – A single-header ANSI C immediate mode cross-platform GUI library | news.ycombinator.com | 2022-12-23

    Not exaclty -- it looks like it's pretty overkill for my needs

    I'm looking for something more like websocketpp[0], or even just grpc without a requisite proxy. uWebsockets looks really promising, being header only, but in the fine print requires a runtime library. unfortunately, none of that ecosystem seems to use cmake, making integrating it that much more of a pain.

    why use cpp for this, I'm sure some HNer will ask. the ray tracer itself is using cuda, that's why. I've also debated

    - running it as a grpc server and having some proxy in a more web-accessible language

    - creating python bindings and using python to make a websocket/http server for it

    neither of those are out of the question, but they're not my first choices, because I'd like to keep the build & execution simple. introducing dependencies, especially other executables, is in conflict with that.

    i don't need anything particularly scalable -- a threaded implementation, or one using select() would be fine, if not preferable.

  • heavydb

    HeavyDB (formerly OmniSciDB)

  • tiny-cuda-nn

    Lightning fast C++/CUDA neural network framework

    Project mention: A CUDA-free instant NGP renderer written entirely in Python: Support real-time rendering and camera interaction and consume less than 1GB of VRAM | reddit.com/r/Python | 2022-12-20

    This repo only implemented the rendering part of the NGP but is more simple and has a lesser amount of code compared to the original (Instant-NGP and tiny-cuda-nn).

  • Sonar

    Write Clean C++ Code. Always.. Sonar helps you commit clean C++ code every time. With over 550 unique rules to find C++ bugs, code smells & vulnerabilities, Sonar finds the issues while you focus on the work.

  • roc-toolkit

    Real-time audio streaming over the network.

    Project mention: PipeWire 0.3.46 (2022-02-17) | reddit.com/r/linux | 2022-02-17

    There's already support in PipeWire for Roc. It's probably not enabled in most distros, considering Roc's latest stable release is quite ancient.

  • nCine

  • MocapNET

    We present MocapNET, a real-time method that estimates the 3D human pose directly in the popular Bio Vision Hierarchy (BVH) format, given estimations of the 2D body joints originating from monocular color images. Our contributions include: (a) A novel and compact 2D pose NSRM representation. (b) A human body orientation classifier and an ensemble of orientation-tuned neural networks that regress the 3D human pose by also allowing for the decomposition of the body to an upper and lower kinematic

    Project mention: Achieving cheap mediocre FBT using 2 cameras, machine learning, and triangulation | reddit.com/r/VRchat | 2023-01-23

    Also google says that Mocapnet has some sort of blender workflow, which would likely be a valid starting point if you ever stop with the 2d methods.

  • ov2slam

    OV²SLAM is a Fully Online and Versatile Visual SLAM for Real-Time Applications

    Project mention: Questions for SLAM/SfM for Dense 3D Reconstruction (DSO vs ORB, Monofusion etc.) | reddit.com/r/computervision | 2022-03-11

  • tscns

    Project mention: A new nanosecond clock for x86 Linux/Windows | reddit.com/r/cpp | 2022-06-26

    tscns is a low overhead nanosecond clock based on x86 TSC instruction. It provides a resolution with 1 nanosecond precision for both LInux and Windows, and the latency of getting timestamp is less than 10 ns. It's also closely synchronized with the system clock, which makes it a good alternative of standard system clocks.
