A lightweight, experimental 3D game engine built with modern C++ and OpenGL, featuring an integrated editor and entity-component architecture.
- Modern OpenGL 4.3+ pipeline with custom shader support
- PBR materials with multi-texturing
- Instanced rendering for large-scale scenes
- Directional and spot lighting
- Skybox support
- Entity-component system for flexible object composition
- Hierarchical scene graph with transform inheritance
- Model importing (OBJ, FBX, glTF via Assimp)
- Built-in geometry primitives
- ImGui based interface
- Gizmo manipulation tools
- Real-time viewport preview
- Project Manager
Note: The editor is in early development and doesn't yet expose all engine features.
Currently Windows-only with MSVC compiler support. Linux support may work with modifications but is untested.
Prerequisites: Windows, OpenGL 4.3+, Visual Studio 2019+, CMake 3.14+
git clone https://github.com/OriginalDCAM/hellfire.git
cd hellfire
mkdir build && cd build
cmake .. -G "Visual Studio 16 2019" -A x64
cmake --build . --config Release#include "hellfire/scene/Scene.h"

auto* scene = new hellfire::Scene("My Scene");
auto material = hellfire::MaterialBuilder::create("Sphere Material");
material->set_texture("textures/earth.jpg", hellfire::TextureType::DIFFUSE);
hellfire::EntityID sphere = hellfire::Sphere::create(scene, "Earth", {
.material = material,
.position = glm::vec3(0, 0, 0),
.scale = glm::vec3(5.0f)
});Hellfire uses a composition-over-inheritance entity-component system, providing flexibility and maintainability. Entities can be composed of any combination of components at runtime, enabling data-driven scene construction and simplified serialization.
- Windows-only (currently)
- MSVC compiler required
- Editor UI incomplete
- No hot-reload for C++ scripts
- Shadows not yet implemented
