| 5 | <code class="function">memoryBarrierAtomicCounter</code> waits on the completion of all accesses resulting from the use of | |
| 6 | atomic counters and then returns with no other effect. When this function returns, the | |
| 7 | results of any modifications to the value of atomic counters will be visible | |
| 8 | to any access to the same counter from other shader invocations. In particular, | |
| 9 | any modifications made in one shader stage are guaranteed to be visible to accesses | |
| 10 | performed by shader invocations in subsequent stages when those invocations were triggered by the | |
| 11 | execution of the original shader invocation (e.g., fragment shader invocations for a primitive resulting | |
| 12 | from a particular geometry shader invocation). | |
