bufferWithArgs Draw Arguments のバッファ
argsOffset Draw argument があるバッファのバイトオフセット

説明

"draw procedural geometry" コマンドを追加。

When the command buffer executes, this will do a draw call on the GPU, without any vertex or index buffers. The amount of geometry to draw is read from a ComputeBuffer. Typical use case is generating an arbitrary amount of data from a ComputeShader and then rendering that, without requiring a readback to the CPU.

This is only useful on Shader Model 4.5 level hardware where shaders can read arbitrary data from ComputeBuffer buffers.

Buffer with arguments, bufferWithArgs, has to have four integer numbers at given argsOffset offset: vertex count per instance, instance count, start vertex location, and start instance location. This maps to Direct3D11 DrawInstancedIndirect and equivalent functions on other graphics APIs. On OpenGL versions before 4.2 and all OpenGL ES versions that support indirect draw, the last argument is reserved and therefore must be zero.

頂点シェーダーで、通常、いくつかのバッファからデータをフェッチするのに SV_VertexID や SV_InstanceID の入力変数を使用します。
