3D Model Viewer v1.0

🧱 3D Model Renderer

A real-time 3D renderer built with C++, OpenGL, and ImGui, featuring modern rendering techniques such as deferred shading, physically-based materials, and post-processing effects. This project serves as a personal graphics engine prototype with a modular UI for experimentation and learning, following the lessons of the learnopengl site.

✨ Features

✅ Rendering Pipeline

• Forward Rendering
• Deferred Rendering (G-Buffer setup and lighting pass)
• Debug Views: Inspect G-buffer contents like Albedo, Normals, Depth, Material Props, etc.

✅ Materials & PBR

• PBR workflows with support for:
  • Albedo
  • Metallic
  • Roughness
  • Normal Maps
  • Height Maps (Parallax Occlusion Mapping)
• Multiple material slots per model
• Real-time material editing UI

✅ Post-Processing Effects

• Bloom with configurable blur passes
• Exposure and Gamma correction

✅ Lighting System

• Directional and Point Lights
• Real-time UI controls (position, intensity, toggles)
• Visual debug of lighting properties

✅ UI (powered by ImGui)

• System information & OpenGL details
• FPS graph
• Scene overview & object transformations
• Material editor
• Post-processing toggles
• Camera control and debug panels

Deferred Rendering Exercise

Graphics Engine Exercise 1 – Deferred Renderer

Overview

This release contains the implementation of Exercise 1 for the Graphics course: Building a Deferred Renderer.

The objective of this exercise was to construct the core framework for a deferred rendering pipeline, including the necessary model loading, base rendering, G-Buffer setup, geometry pass and lighting pass.
