Description
Clears a UAV to the multi-channel floating point value provided. Should only be called on UAVs with a floating point format, or on structured buffers. Structured buffers are treated as a regular R32_UINT buffer during the clear operation, and the Values.X component is copied directly into the buffer without any format conversion. (Y,Z,W) of Values is ignored. Typed floating point buffers undergo standard format conversion during the write operation. The conversion is determined by the format of the UAV.
