Work in progress framework using opengl to later use for personal projects

Acknowledgments

Currently used libraries: SDL2, GLM, DevIL, stb_image, GLAD and Assimp

for library licenses see Library Licenses.md

Structure inspired by the OverlordEngine from Digital Arts and Entertainment

Features:

• Basic Physically Based Rendering
• HighDynamicRange Environment maps
• Diffuse IBL
• Deferred and Forward rendering
• Stereoscopic Normal map encoding and decoding for optimal use of G-Buffer
• Buffer Display mode
• Scenegraph Entity Hirachy
• Entity Component System
• Singleton Pattern for things like WINDOW, INPUT, TIME, CAMERA etc
• Observer Pattern for input
• Factory Pattern for Content Managment
• Mesh Filter -> Vertex buffer building depending on material needs
