## Detailed Description

BufferInput is a Command which can be added to the list of commands in the Pass of an Effect. When executed, it will expose the buffer as a sample to the shaders in the render pass. The shaders must declare a sampler with the name given in the BufferInput's `sampler` property.

This can be used for sharing intermediate results between the different passes of an effect.

See also TextureInput.
