Renderer Architecture

Render Layers

• Output composed of multiple 'layers'
  • Scene
  • Debug Objects
  • GUI
• These layers are 'merged', resulting in the complete output.
  • Secondary commands executed within a Primary Command Buffer for submission.
  • This architecture is trivially parallelizable; Layers are independent from one another.
    • May require buffering resources for frames in flight.

// Layer Rendering Pseudocode
Clear(primaryCommandBuffer); 

for(layer in layers) {
    layer->RecordCommands(secondaryCommandBuffers[layer]); //This can be done in parallel!
}

await RenderTasksComplete(); 

ExecuteSecondaryCommands(primaryCommandBuffer, secondaryCommandBuffers); //Play back the secondary commands 

Present(primaryComandBuffer); 

SubmitCommands(graphicsQueue, primaryCommandBuffer);

• Use C++ Polymorphism for simplicity
