GLAB

This serves as my final project for Computer Graphics course at ESIEE during 2017 Fall.

I may continue improving it for fun. Some features may not work well on AMD card.

Features

• CMake
  • Windows + vcpkg
  • Linux
• C++ 11~17
• Wavefront.obj
• Modern OpenGL 4.5+ AZDO
  • Bindless Texture
  • Indirect rendering
  • Direct State Access
  • Shader Storage Buffer
• Batch Rendering
• Deferred Rendering
• Quaternion Rotation
• Cascaded Shadow Maps
• Point light
  • Bloom
  • Volumetric Effects
  • Directional shadow mapping
  • Omnidirectional shadow mapping
• Physically Based Rendering
  • HDR environment
  • Image-based lighting
  • PBR metallic roughness
  • Fresnel Schlick
  • Cook-Torrance BRDF
  • Microfacet GGX+Smith
  • Multiple-Scattering Microfacet BSDFs with the Smith Model
• Separable Subsurface Scattering
  • Phong lighting
  • PBR lighting
  • Gaussian blur
  • Transmittance
  • Shadow
• Post-process
  • ACES tone mapping
  • Basic eye adoption
  • Gamma correction
  • UE4.25 Auto Exposure

To-fix

• Light source should be brighter.
• Adjust bloom range based on depth.
• Redone the pipeline, reduce VRAM cost.

Dependencies

• GLEW - OpenGL loading library
• SDL2 - Window & Context
• ImGui - User interface
• GLM - Math operations
• STB - Image loading
• Magic Enum C++
