memoryBarrierImage — controls the ordering of operations on image variables issued by a single shader invocation
void memoryBarrierImage(
|
void); |
memoryBarrierImage waits on the completion of all memory accesses resulting
from the use of image variables and then returns with no other effect. When this function returns, the
results of any modifications to the content of image variables will be visible
to any access to the same buffer from other shader invocations. 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).
