OpenGL Renderer

A modern real-time 3D renderer built with C++20 and OpenGL 4.6.
Designed for experimenting with physically-based rendering, post-processing effects, and modern GPU techniques.

What is this?

OpenGL Renderer is an interactive rendering engine that lets you load scenes, configure materials, and visualize the results in real time. It features a clean editor interface built on ImGui, a deferred shading pipeline with PBR lighting, and a live shader editor.

Highlights

  • Real-time rendering — Deferred pipeline with PBR shading, IBL, and tone mapping.
  • Live shader editor — Edit GLSL shaders and see changes immediately.
  • Post-processing stack — SSAO, SSR, FXAA, and more.
  • Scene hierarchy — Outliner, transform gizmos, and material viewer.
  • Soft shadows — SDF-based soft shadow rendering.

Getting Started

  1. Clone the repository and open OpenGL.sln in Visual Studio.
  2. Build for x64 in either Debug or Release configuration.
  3. Run the executable — a window with the editor and viewport will appear.
  4. Load a scene or explore the default scene to get started.
