OpenGL Tutorials

This site contains a series of tutorials on computer rendering techniques taught using OpenGL. It contains algorithm descriptions and mathematical details as well as all the programming code required to go from basic windows creation to complex rendering effects. It primarily uses OpenGL 4 (up to feature level 4.4) but also indicates how to implement various effects using OpenGL 3.x if required.

OpenGL Tutorials

Topics covered include (but not limited to):

SDL2 window creation
OpenGL Vertex Arrays (VAO), Vertex Buffers (VBO), Index Buffers (IBO) and Uniform Buffers (UBO)
Debug call-backs
FPS style camera
Point and Spot lighting
Gouraud and Phong shading
BRDFs: Blinn-Phong and GGX shaders
Shader subroutines
Textures (BMP and compressed KTX)
Scene/Model loading using Assimp
Environment mapped refractions
Real-time dynamic reflections (planar and environment mapped)
Real-time Shadow mapping (spot and omni-directional point shadows)
Percentage Closer Filtering (PCF) shadows
Percentage Closer Soft Shadows (PCSS)
Normal Mapping
Parallax Occlusion Mapping
Tessellation shaders (PN triangles)
Deferred Rendering
High Dynamic Range (HDR) and Tone Mapping
Bloom effects
Horizon Based Ambient Occlusion (HBAO)
Volumetric Lighting

These tutorials were created as part of my job but are now made available online in case they may help anyone looking to learn this particular subject matter.
