Top 23 C++ Matrix Projects

As for math, that was the easiest choice as of yet. No doubt, GLM is a "gold standard" at this point. For OpenGL it is, at least. But, like with a lot of the other APIs, I decided to build a wrapper around it rather than directly reference the library in the engine's code. And for physics, well, I had not come upon that answer just yet. I did try to make my own physics logic at some point. And while it was, surprisingly, successful, I wanted more than just a simple physics layer. I wanted something more complex and, more importantly, faster than my implementation. I have not decided upon a physics library yet. But I'll cross that bridge when I come to it.

New nodes can be created pretty cheaply too, but too verbose for a comment. The key to tracking the callsites and assigning them IDs is thread_local local variables generated by the macro:
https://github.com/DmitriBogdanov/UTL/blob/master/include/UT...
When callsite marker initializes (which only happens once), it gets a new ID. Timer then gets this 'callsite_id' an passes it to the forwards-traversal. The way we get function names is by simply remembering __FILE__, __func__, __LINE__ pointers in another array of the call graph, they get saved during the callsite marker initialization too. As far as performance goes everything we do is cheap & simple operations, at this point the main overhead is just from taking the timestamps.

In my latest contribution to the open-source library Theoretica, I tackled Issue #81 focused on refining and enhancing the inline documentation for two central components: mat (the matrix class) and vec (the vector class). This issue was raised to improve the readability and usability of these classes, which are essential in mathematical computations and commonly used across various areas in the library. Proper documentation is key to making complex code accessible to other developers and contributors.
