PBR Engine

This is my second OpenGL engine where the purpose of this project is to learn other rendering techniques and improve both my C++ and OpenGL knowledge.

It's a deferred rendering engine based on the glTF file format.

Features

Implemented

• Physically Based Rendering
  • Metallic Roughness Workflow
  • IBL
  • Specular Glossiness Workflow
• Skybox
• Screen Space Ambient Occlusion
• Fast Approximate Anti-Aliasing
• Debug Mode
• FX
  • Bloom
  • Depth of Field
  • Multiple Tone Mapping

Need to be transfered from the old Engine

• Shadow Mapping (Both Directional and Point)
• Relief Mapping
• Water Rendering

Coming Soon
