Renderer draft

Two sides

Renderer (API/platform agnostic) │ Render API (API/platform specific)

• 2D/3D Renderer │ * Render context
  • Forward, deferred, etc. │ * Swap chain
• Scene graph │ * Framebuffer
• Sorting │ * Vertex buffer
• Culling │ * Index Buffer
• Materials │ * Texture
• LOD │ * Shader
• Animation │ * States
• Camera │ * Pipelines
• VFX │ * Render passes
• PostFX │
• Other things │
  • (eg. reflections, occlusion) │

Where do we start?

• We're going to start with OpenGL
  • Simplest, easiest API (although requires stronger design from our side)
• Step 1: build Render API
• Step 2: build Renderer
• Note: these steps have overlap and mostly aren't dependent
• After that we have a base to render anything we want
• In the future (TBD), we will implement other APIs
