Come up with a structure for the second section of the tutorial

[deccer]

All that tbd, we should VC like last time

Basics

• Colors
• Blending (BlendState)
• Dear Imgui? (it might make sense to manipulate light position/color later why not introduce dear imgui here, we could manipulate the color of the 3 corners of the HelloTriangle to see it in action and also how interpolation by the PS affects the outcome
• Gamma Correction
• Blinn-Phong with hardcoded directional light
• Blinn-Phong materials and lights
• Normal Mapping
• Lights from CPU
  • Point
  • Spot
  • Directional
  • Light Geometry (I think we should use them from the start, for point/spot lights)
  • Debug Lights
• RenderTargets (aka Framebuffers, we need them for Shadows and Defered and whatnot)
  • We could also introduce Framebuffer scaling, like modern games provide a way too (render to 50% of screen res etc) (Quake Chanmpions, Path of Exile on top of my head)
• Shadows
  • Implement basic shadow
  • Fixup with bias, front face culling, PCF
  • Point Light Cubes?
  • Cascade Shadow maps
  • Variance Shadow Maps?
• Frustum Culling?
• Forward+ ... (steal from 3dgep?)
• Deferred Shading
  • Tightly Packed GBuffer?
  • Classical Deferred
  • Tiled/Clustered ... (we could steal from 3dgep? but implement it using our "framework")

PBR

• Rendering equation and basic theory
• Used BRDFs
• Physically based lighting
• IBL with SH

Techniques

• Compute Shaders
• Text Rendering
  • SDF Bitmap fonts? (using compute to generate the font bitmap)
• Particles
• Skeletal Animation
• SSAO
• SSR
• Frustum Culling
• Sky + Clouds
• Reflection probes
• GI
  • Voxel Cone Tracing (see 3dgep?)

Post-processing

• HDR + Tonemapping
• Better camera + Bloom
• Depth of Field
• TAA
• Motion Blur
• Lens flare
