It's actually a fun (for nerds like me, at least) hobby, seeing how it's essentially creating viewable and interactable universes using only math and the power of computers. And the linear algebra and trigonometry involved can be learned without too big of a problem even by not very great or educated mathematicians like me (thank you 3blue1brown for teaching me more than my entire highschool did); and it's a mind-blowing experience itself, combining many "I will never, ever use this IRL" concepts into a practical, working whole.

The features might be "modern" (whatever that means), but C++ is not modern and never will be unless the entire world suddenly starts writing C++20 overnight and all known and maintained code magically transforms as well. Tons of professional C++ developers still write C++ like it's 1998. And tons of actively maintained code is still written in that style as well. And onboarding devs to this new style is not easy either, as it's hard to deny that with all those cool features there has also been an explosion in complexity in an already complex language.

@@clonkex it's a bit messier than that, since you need to take lots of samples per pixel per bounce, and lots of bounces per sample to get a convincing image, so the naive, brute force approach lots of offline renderers use isn't feasible. Different RT GI implementations have different specifics for working around this, but they all generally amount to persisting the amount of light in the world at each point and then iterating on bouncing it around, which has the effect of flowing the light from the source around the scene before it reaches the camera. That said, the actual form of the persisted world lighting is very heavily camera influenced (to the point of being screen space for Q2RTX), so yeah, not a nice clean answer. RT shadows might be pretty much tracing in reverse, but I don't know if I quite count a single bounce as having any direction?

I am programming my own voxel engine in Rust. There is an insane Vulkan powered engine in Rust called Bevy.

Thanks, it is so much more interesting to hear about the engine mechanics than whatever gameplay.

"Flame wars will boost engagement anyway." Truly, a man of inimitable wisdom. (I too have a soft spot for C++, despite being a huge Rust shill. It makes me wanna tear my hair out sometimes, but I did a lot of robotics stuff with it in high school.)

Very nice video! I really appreciate you sharing something non-trivial you've made with bgfx. Not very common on the KZbins. It makes me chuckle (in a good way) to see those Rust-like numeric typedefs and Result in there. After moving to C++17, I sorely missed designated initializers, but liked that I could use some C++-specific features (e.g. templates, namespaces) and ignore the rest.
