Class to place a memory barrier. More...
|Import Statement:||import Qt3D.Render 2.0|
A MemoryBarrier FrameGraph node is used to emplace a specific memory barrier at a specific time of the rendering. This is required to properly synchronize drawing and compute commands on the GPU.
The barrier defines the ordering of memory operations issued by a prior command. This means that if command1 is manipulating a buffer that is to be used as a vertex attribute buffer in a following command2, then the memory barrier should be placed after command1 and setting the appropriate barrier type for vertex attribute buffer.
When a QMemoryBarrier node is found in a FrameGraph branch, the barrier will be enforced prior to any draw or compute command even if these are defined deeper in the branch.
