Description

Physically Based Rendering In OpenGL Using GLTF2 is an OGLDEV YouTube tutorial by Etay Meiri on modernizing an OpenGL pipeline with a glTF 2 metallic-roughness PBR path.

Chapters cover glTF 2 materials, Assimp PBR support, extra textures, vertex and fragment setup, Schlick fresnel, a precomputed BRDF table, specular and diffuse paths, irradiance IBL, and a directional light. Matching source is tagged TUT_64_PBR_GLTF2 on the ogldev repository.

It is for intermediate OpenGL learners who can already load models and write basic shaders and want a structured PBR upgrade.

Access is a free roughly twenty-five-minute YouTube video with source on GitHub and further tutorials on ogldev.org.

It is useful when moving a classic OpenGL sample toward glTF metallic-roughness shading with clear IBL building blocks.
