How to design a flexible framework for rendering algorithms demo

practical for GlobalIllumination code

• A self-contained assert system to check parameter and conditions. It would give a unified feeling.
  • It requires a detailed plan about return value of function call.
• Different Camera, Camera Parameter leads to Uniform Buffer Update.
  • Camera holds a device resource to update by itself ?
  • Camera notify 3rd module to do that ?
• Different Render Target: Final Scene, Scene Depth, Shadow Map, G-Buffer
• Mesh Data & Device Buffer
• Different Render Pass & Different Render Target & Different Vertex Layout
• UI system and Font Rendering
• Separate Init Stage to make it more flexible

Case Study

There is a small framework for D3D12 in DeferredTexturing in github. I would give a review and hope to learn something.

Window and swap chain update

• a class Window to handle stuff involving with windows system.
• a class App register a call back function to handle swap chain rebuild.

User options

• It is a little complicated design.
  • class Setting
  • class SettingsContainer
  • struct ConstantBuffer
    • A wrap to Raw D3D12 Buffer to make it easy to use in Framework.
• It Put it in framework to make it deeply involved with application. It should give a way and let app to do it.
  • Perhaps by pure virtual function to enforce app to implement its own way.

It takes a long time to startup

• After profiling, LoadMaterialResources(meshMaterials, fileDirectory, settings.ForceSRGB, materialTextures)
• Is is possible to apply multi-threading ?

Shader Management

• The exposed interface is quit simple.
  • The main interface is CompileFromFile()
  • The main data type is CompiledShaderPtr
