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.
For a ComputeBuffer that uses a counter, Metal and Vulkan platforms don't have native counters and use separate small buffers that act as counters internally. These small buffers are bound separately from the ComputeBuffer and count towards the limit of possible buffers bound (31 for Metal, based on the device for Vulkan).
On the shader side, ComputeBuffers with default ComputeBufferType map to StructuredBuffer<T> and RWStructuredBuffer<T> in HLSL.

Properties Property Description count Number of elements in the buffer (Read Only). name The debug label for the compute buffer (setter only). stride Size of one element in the buffer in bytes (Read Only). Public Methods Method Description BeginWrite Begins a write operation to the buffer EndWrite Ends a write operation to the 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. Static Methods Method Description CopyCount Copy counter value of append/consume buffer into another buffer.RetroSearch is an open source project built by @garambo | Open a GitHub Issue
