Using the same texture buffer as SRV and UAV simultaneously on the same compute shader

Meir Ivry · 2012-04-27T11:19:57

Hi, I have a 2D texture buffer that I use on a compute shader. I nead read access to it using SampleLevel method and a write access to it. Since SampleLevel is defined for Texture2D buffer and not for RWTexture2D - using it as UAV only is not an option. Can I use the same texture as Unordered Access View and as Shader Resource Views simultaneously on the same compute shader? Thanks, Meir.

Is it enough to unbind the SRVs and UAVs after each iteration or do I need to dispose them and create new ones each time?[/quote]
Yes, you can unbind them and reuse them (I used to just swap them after each iteration if I need to chain multiple iterations in a feedback fashion). Just make sure you unbind them in the right order (or just to be sure, unbind them both first, them bind them back).
