  • vcpkg

    C++ Library Manager for Windows, Linux, and MacOS

    Latest mention: Thinking of ending my love affair with vcpkg | dev.to | 2021-01-14

    There are instances where you would need to keep distinct copies of vcpkg sources, and having a tool built in it implies the tool needs to be built before it can be used. There are efforts to bring vcpkg binary distribution. ### The package manager which can't handle multiple library versions You would assume you would have support for maintaining different version for same library but vcpkg can't do that. The only way until https://github.com/microsoft/vcpkg/pull/15565 is resolved is clone vcpkg in seperate folder and build vcpkg, git checkout port related files to older version and built it.

  • spdlog

    Fast C++ logging library.

    Latest mention: What tools similar to std::optional should you be using? | reddit.com/r/cpp | 2021-01-02

    Yeah. I just added spdlog to a project and it's infuriating how the API expects things to be held in a shared pointer. Let me design my own ownership semantics!

  • tinyrenderer

    A brief computer graphics / rendering course

    Latest mention: Learn 3D Computer Graphics Programming from Scratch | news.ycombinator.com | 2020-12-29

    To be fair, Handmade Hero is for a complete game with sound, effects, input, etc. This course looks to be focused on a realtime software renderer with the ability to read/write geometry and textures. HH is also a bit overwhelming.

    I think what specific tutorial might go for depends on that individual's background and goals. I know a bunch of people who work in games/vfx who use tools like Maya/Houdini every day. They don't need a lot of help learning 3d concepts, but are interested to see the pros/cons of different implementations. They aren't always interested in realtime or optimizations. Here are the free resources that normally come up:

    https://github.com/ssloy/tinyrenderer/wiki -- tinyrenderer, tinyraycaster, tinyraytracer

    Latest mention: How I minimize the Webkinz App on Macbook | reddit.com/r/Webkinz | 2021-01-08

    I’m not sure if it’s because my MacBook is older and I never update it, but I had to download a separate application that lets me change the volume of specific windows. The one I use is called BackgroundMusic, it’s free and I find it easy to navigate but there’s all sorts of other options I found on Google!

    Gaming meets modern C++ - a fast and reliable entity component system (ECS) and much more

    Latest mention: My Simple c++ ECS implementation | reddit.com/r/roguelikedev | 2021-01-15

    The API reminds me a bit of EnTT (Disclaimer: I am considered a contributor, even through its just a few lines). It makes heavy use internally of type-erasure (which would among other things remove the need for a common base class component) and other tricks and ideas you might get some inspiration from for your implementation.
