GPU data buffer, mostly for use with compute shaders.
ComputeShader programs often need arbitrary data to be read & written into memory buffers.
ComputeBuffer class is exactly for that - you can create & fill them from script code,
and use them in compute shaders or regular shaders.
Compute buffers are always supported in compute shaders. Compute shader support can be queried runtime using SystemInfo.supportsComputeShaders. See the Compute Shaders Manual page for more information about platforms supporting compute shaders. In regular graphics shaders the compute buffer support requires minimum shader model 4.5.
On the shader side, ComputeBuffers with default ComputeBufferType map to StructuredBuffer<T> and RWStructuredBuffer<T> in HLSL.

| count | Number of elements in the buffer (Read Only). |
| name | The debug label for the ComputeBuffer. This name shows up in profiling and frame debugger tools, wherever supported. |
| stride | Size of one element in the buffer (Read Only). |
| ComputeBuffer | Create a Compute Buffer. |
| GetData | Read data values from the buffer into an array. The array can only use blittable types. |
| GetNativeBufferPtr | Retrieve a native (underlying graphics API) pointer to the buffer. |
| IsValid | Returns true if this compute buffer is valid and false otherwise. |
| Release | Release a Compute Buffer. |
| SetCounterValue | Sets counter value of append/consume buffer. |
| SetData | Set the buffer with values from an array. |
| CopyCount | Copy counter value of append/consume buffer into another buffer. |
