Stuff I make while learning to write a PBR rasterizer in OpenGL

Dabrovic Sponza scene with the Adam Head, 2 point lights and a flat shaded sphere

Roadmap:

• Basic OpenGl stuff: VAOs, VBOs, shaders, textures
• Phong materials
• Basic lighting: ambient lights, directional lights, point lights, spot lights
• 3D Model loading
• Basic ImGUI UI: viewport
• Entity hierarchy
• Primitives: cubes, spheres, cylinders, pyramids
• Good ImGUI UI: entities property panel, import models, add lights, multiple cameras, material manager and editor
• Material preview on sphere
• 3D move/rotate/scale gizmos
• Enable/Disable object (Visibility)
• Anti-aliasing
• Selected object outline with stencil buffer
• Face culling, depth testing
• Better GLSL
• Deferred shading
• Shadows
• Normal maps
• HDR
• Ambient Occlusion
• PBR workflow!
• HDRI lighting
• Node graph-based material system
• Great ImGUI UI: Asset Manager, Icons, Render Settings Panel, Image Export
• Ray tracing?
• Compute shaders?

Dependencies (so far):

• OpenGL w/ GLAD & GLFW
• spdlog
• Dear ImGUI - docking branch
• ImGuizmo
• stb_image.h
• Assimp library
