# SGE - Simple Game Engine  

SGE (Simple Game Engine) is a learning project aimed at building a minimalistic game engine using **DirectX 12**. This project is structured as a roadmap consisting several tasks, designed to teach and implement various modern rendering techniques and systems. 

This project is **actively under development**, and its purpose is to experiment and test various ideas in graphics engine development.  

### Important:  

- The project may contain **low-quality, messy, and suboptimal code**.  

- Errors, bugs, and missing or incorrect functionality may exist.  

- The code is intended for **personal use** and experimentation only.  

> **Please note**: This project is **not intended for production use** or for creating finished products.  

## Roadmap  

---

  ✔ 1. Initialize D3D12 context: Set up the DirectX 12 framework.

  ✔ 3. Load simple models without animation: Import static models such as teapots, cars, and tanks.

**4. Load mip-mapped textures**: Support diffuse, normal, specular, and gloss maps.  

**5. GPU compressed textures**: Use compressed texture formats for better performance.  

**6. Phong lighting**: Calculate lighting from direct and point lights in the pixel shader.  

**7. Fog effect**: Add fog either in the pixel shader or as a post-process effect.  

**8. Deferred lighting**: Implement direct, capsule, point, and spot lights with a deferred pipeline.  

**9. Cook-Torrance BRDF and Image-Based Lighting (IBL)**: Add realistic PBR lighting.  

**10. HDR pipeline**: Add auto exposure and tone mapping for high dynamic range rendering.  

**11. Bloom effect**: Implement a post-process bloom effect.  

**12. Dynamic environment reflections**: Render cube maps for dynamic reflections.  

**13. Soft shadows**: Implement soft shadows using techniques like SM+PCF, VSM, or ESM.  

**14. SSAO**: Implement screen-space ambient occlusion.  

**15. SSLR**: Add screen-space local reflections.  

**16. Load skinned mesh animations**: Import animated models and process on the GPU.  

**17. Animation blending**: Combine multiple animations (e.g., running and shooting).  

**18. MSAA**: Support multi-sample anti-aliasing.  

**19. Particle system**: Create a system that supports 10,000+ particles.  

## Project Goals  

The SGE project is designed to:  

- Learn DirectX 12 fundamentals and advanced features.  

- Implement modern rendering techniques used in game engines.  

- Build a foundation for further exploration of game engine development.
