public static function CopyCount(src: ComputeBuffer, dst: ComputeBuffer, dstOffset: int): void;
public static void CopyCount(ComputeBuffer src, ComputeBuffer dst, int dstOffset);

Parameters

src Append/consume buffer to copy the counter from.
dst A buffer to copy the counter to.
dstOffset Target byte offset in dst.

Description

Copy counter value of append/consume buffer into another buffer.

Append/consume buffers keep track of the number of elements in them with a special counter variable. CopyCount takes an append/consume buffer as src, and copies its counter value into dst buffer at given byte offset.

This is most commonly used in conjunction with Graphics.DrawProceduralIndirect, to render arbitrary number of primitives without reading their count back to the CPU.
