A modern 3D Game Engine built from scratch in C++ and OpenGL.

Overview

Genesis Engine is a custom-built game engine focusing on high-performance rendering and retro-style aesthetics modernized with advanced lighting techniques. It implements a full BSP (Binary Space Partitioning) pipeline similar to the Quake/Source engines but enhanced with modern lighting capabilities.

Key Features

Lighting & Rendering

• BSP-Based Rendering: Efficient visibility culling and collision detection.
• Offline Light Baking: High-performance static lighting with zero runtime cost.
• Soft Shadows & Ambient Occlusion:
  • Source-Engine style radiosity approximation.
  • Lightmap smoothing (3x3 Blur Pass) for clean, artifact-free shadows.
  • Edge dilation prevents texture bleeding artifacts.
• Colored Lighting: Support for multi-colored point and directional lights (Orange, Blue, Purple, Warm Sun).

Architecture

• Core: C++17 with minimal dependencies (GLAD, GLFW, GLM).
• Physics: AABB-based collision detection against BSP trees (Quake-style trace).
• Asset Pipeline: Custom JSON map format with OBJ fallback.

Building and Running

Prerequisites

• CMake 3.10+
• C++17 Compiler (GCC/Clang/MSVC)
• OpenGL 4.5+ capable GPU
