GPU graphics data buffer, for working with geometry or compute shader data.
ComputeShader programs often need to read or write arbitrary data from or to memory buffers, and some rendering algorithms need a lower level access or control over geometry data than what is provided by the Mesh class. You can use GraphicsBuffer for these cases. You create the buffers from C# scripts, and then fill them with data using either C# scripts or compute shader programs.
A graphics buffer is similar to an array in C#, in that it has a number of elements (count) of the same size (stride). You must supply the intended buffer usage (target) when you create a GraphicsBuffer; for example, you must pass GraphicsBuffer.Target.Index for the buffer to be usable as a geometry index buffer.
When you have finished working with the buffer, you must manually release the GPU memory should be released. You can do this using C# dispose pattern, or by calling Release.
