✨ NAME ✨

okay so this is the manpage for memoryBarrierAtomicCounter, from the 3G manual bestie 💖

It controls the ordering of operations on atomic counters issued by a single shader invocation. periodt.

🎀 DECLARATION 🎀

void memoryBarrierAtomicCounter(void);

💫 DESCRIPTION 💫

So memoryBarrierAtomicCounter literally just waits on the completion of all accesses resulting from the use of atomic counters, and then returns with no other effect. that's it, that's the whole vibe. no cap. 🫶

When this function returns, the results of any modifications to the value of atomic counters will be visible to any access to the same counter from other shader invocations. the way that visibility just shows up? iconic.

In particular, any modifications made in one shader stage are guaranteed to be visible to accesses performed by shader invocations in subsequent stages when those invocations were triggered by the execution of the original shader invocation (e.g., fragment shader invocations for a primitive resulting from a particular geometry shader invocation). like, the pipeline said "you're welcome" 💅
