Toy Renderer (V2)

Build and Run

cmake -Bbuild -GNinja -DCMAKE_TOOLCHAIN_FILE=$(VCPKG)/scripts/buildsystems/vcpkg.cmake
./build/ToyRenderer/ToyRenderer

Plan

Rendering

• GPU-Driven
• Mesh shaders
• Occlusion CPU & GPU
• MIPMAPS
• LODs
• Frustrum culling
  • AABB bounding box
    • works but still buggy at the extremities of Sponza for big objects, the 8 rather than only 2 extremities should be tested, or something else idk
  • Maybe some more clever techniques like OOB / Convex Hull
  • Use hiearchical test?
• Debug Pass
  • draw triangle wireframe
  • draw square
  • draw boxes
• Allow to display wireframe / Bounding Box conditionnally
• Deferred Pipeline
  • PBR (buggy)
  • IBL
• Forward (not used)
  • for transparent objects only
• "Bindless" textures / indexed textures (Partial, for deferred only)
• Local Illumination
  • SSAO
• Global Illumination
  • A basic version of SSAO
  • A more complex thing like voxel based or something like that?
• Shadows
  • Basic Directionnal lights
  • Percentage closer filtering
    • A better filtering pattern
  • Point lights
  • Shadow Cascade
  • Adapt projection to camera
• Antialising
  • FXAA
  • TAA
  • MSAA for forward
• More
  • Fog!
  • (basic) clothes simulation!
  • Fire

Libs

• Dear ImGui
• FastGLTF
• GLFW
• GLM
• JsonCpp for reading / writing registry.json (for storing CVARS mainly)
• Stbimage
• Shaderc to recompile shaders during execution
• VMA
• Vulkan

Tools

• RenderDoc
• Nvidia Nsight
