如何将MTLTextures组合到currentDrawable中

// 假设你已经有了一个MTLCommandBuffer和一个MTLRenderPassDescriptor
guard let commandBuffer = commandQueue.makeCommandBuffer() else { return }
guard let renderPassDescriptor = currentRenderPassDescriptor else { return }

// 设置颜色附件
renderPassDescriptor.colorAttachments[0].texture = yourMTLTexture
renderPassDescriptor.colorAttachments[0].loadAction = .clear
renderPassDescriptor.colorAttachments[0].clearColor = MTLClearColor(red: 0.0, green: 0.0, blue: 0.0, alpha: 1.0)

// 创建并配置渲染管道状态
let pipelineState = createPipelineState()
guard let renderEncoder = commandBuffer.makeRenderCommandEncoder(descriptor: renderPassDescriptor) else { return }
renderEncoder.setRenderPipelineState(pipelineState)

// 绑定纹理到渲染编码器
renderEncoder.setFragmentTexture(yourMTLTexture, index: 0)

// 执行渲染命令
renderEncoder.drawPrimitives(type: .triangle, vertexStart: 0, vertexCount: vertices.count)
renderEncoder.endEncoding()

// 提交命令缓冲区
commandBuffer.present(currentDrawable)
commandBuffer.commit()
