Creating an indirect command buffer

Overview

An indirect command buffer stores encoded GPU commands persistently. Using an indirect command buffer, you can encode a command once and reuse it multiple times. You can also encode commands into an indirect command buffer simultaneously with multiple threads on the CPU or with a compute kernel on the GPU.

To create an indirect command buffer, first create an MTLIndirectCommandBufferDescriptor instance and configure the descriptor’s properties. Then call makeIndirectCommandBuffer(descriptor:maxCommandCount:options:) on an MTLDevice instance to create the indirect command buffer.
